Applications - UYGULAMALAR

AURAS-2000 GmbH firması,

Budapeşte/Macaristan Türkiye Temsilcisi (Tarık Tekeş) tarafından satılan kimyasal bazlı AUFLOW-70 kanal refrakter malzemesi, aşınan veya daimi kanal kaplaması olarak çok önemli avantajlara sahiptir.
Döküm kanallarında AUFLOW-80 kullanılır.

Yeni geliştirilen kimyasal bağlı malzeme, yıpranmadan kaynaklanan onarım işlerinin, ısıtma dahil olmak üzere çok hızlı bir şekilde gerçekleştirilmesine imkan sağlar. Isıtma işlemi, su içermeyen refrakter malzemeden dolayı hızlı bir şekilde gerçekleşir. Bu malzemedeki kimyasal bağlanmayı nanoteknolojik prosesler sağlar.
Bu refrakter malzemenin başka pozitif özellikleri de vardır: çok düşük gözenek oranı, buna rağmen nemi çok hızlı uzaklaştırma özelliği, son derece yüksek ısı dayanımı ve mekanik zorlanmaya karşı mükemmel sağlamlık.
Malzeme, iyi temizlenmiş olan duvara nano parçacıklar sayesinde iyice yapışır.
Malzemenin kimyasal bağlanma özelliği ise, 400-500 oC’ye varan duvar sıcaklıklarında hızlı bir sıcak onarımın yapılmasına olanak sağlar.
Kimyasal bağlı AUFLOW-70 ve AUFLOW-80 refrakter malzemeleri yerleştirme yöntemi
Refrakter malzeme, 1 tonluk big-bag çuvallar veya istek üzerine 25’er kg’lık kağıt torbalar halinde, bağlayıcı malzeme AUSOL 1540 ise, 1000 litrelik plastik hazneler veya daha küçük plastik bidonlar içinde teslim edilir.

Refrakter malzeme, sadece birlikte gönderilen bağlayıcı malzemelerle karıştırılabilir. Su veya başka bir bağlayıcı malzemenin ilave edilmesi kesinlikle sakıncalıdır.
Karıştırma işleminde bir cebri karıştırıcının kullanılması avantaj sağlar. Burada malzemenin kıvamı, kullanılacak bağlayıcı malzeme miktarına bağlı olarak nispeten geniş sınırlar içinde ayarlanabilir.
Yakl. %6-7 oranında bağlayıcı malzeme kullanıldığında vibrasyon uygulanabilir. Bağlayıcı malzeme oranı %8-10’u geçince malzeme kendiliğinden akmaya başlar ve herhangi birvibrasyon gerekmez. Bu durumda, yerleştirme işlemi için normal bir beton pompası kullanılabilir.

Yıpranan astar kaplamanın yapışan malzemelerden ve kirden arındırılması şarttır. Bunun için uygun temizleme aletleri kullanılmalıdır. Kalıplar monte edildikten sonra yeni malzeme yerleştirilebilir. Elverişli aletler kullanıldığı takdirde, 1-2 saat içinde 15-25 ton arasında malzeme yerleştirmek mümkündür. Dolayısıyla, normal bir beton pompası ile saatte 14-15 ton malzeme sorunsuzca yerleştirilebilir.

Duvarın sıcaklığı yerleştirme işlemi sırasında doğal olarak 150-500 oC’ye varabilir. Bu sıcaklık, yeni refrakter malzeme yerleştirilirken herhangi bir sorun yaratmaz. Priz alma süresi ise, ortam sıcaklığına ve kullanılan bağlayıcı malzemenin miktarına bağlı olarak 0,2 ile 2 saat arasındadır. Kalıplar ancak malzeme sertleştikten sonra çıkarılmalıdır.

Kalıplar alındıktan sonra hemen ısıtma işlemine başlanabilir. Isıtma işlemindeki sıcaklık saat başına doğal olarak 100-200 oC arasında olabilir.
Yukarıda açıklanan yöntem ile, kanal kaplaması 24 saatlik bir periyot içinde “sıcak üzerine
sıcak” şeklinde komple yenilenebilir.
Yeni yerleştirilen refrakter malzemenin miktarı hesaplanırken 1 ton ham demir başına 0,22- 0,35 kg esas alınmalıdır. Burada kullanılacak olan refrakter malzeme miktarının elbette fırın işletimi ile kanal kullanım teknolojisine ve kanalın niteliğine bağlı olacağı göz önünde bulundurulmalıdır.

Kimyasal bağlı AUFLOW kanal refrakter malzemelerinin avantajları...
- Hazırlanan yeni refrakter malzeme daha önce iyice temizlenmiş olan duvar kaplamasının üzerine yerleştirilir. Böylece, malzemeye bağlı işletim giderleri sıradan teknolojilere kıyasla azaltılır.

- Yeni kanal profilinin kaplanması için gereken malzeme, eski kaplamanın temizlenmesi için çıkarılan malzemeden çok daha fazla değildir. Malzeme, eski kaplamaya çok iyi yapışma özelliğine sahip olduğundan, her halükarda kalıcı kaplama ortaya çıkıncaya kadar temizleme yapılması şart değildir.

- Duvarın temizlenmesi normal motorlu kazıma/kırma aletleri ile gerçekleştirilir.

- Orijinal kanal profili çok hızlı bir şekilde tekrar oluşturulabilir ve böylece tek kanallı
teknolojide üretim süresi açısından önemli avantaj sağlanabilir.
- Malzeme kendiliğinden akma özelliğine sahip olduğundan özel yerleştirme ekipmanları gerekli değildir. Ancak, kanaldan sonraki bölümlerde vibrasyon teknolojisi uygulanabilir.

- Malzeme, karıştırıcıdan doğrudan kanalın içine dökülebilir veya çalışma hızının önemli ölçüde arttırılması için beton pompası ile yerleştirilebilir.

- Malzemenin kıvamı, kanalın sıcaklığına bağlı olarak, bağlayıcı malzeme miktarı ile nispeten geniş sınırlar içerisinde ayarlanabilir. Malzemenin dayanıklılığı bundan olumsuz etkilenmez.

- Katı kontrollere tabi tutulması gereken bir ısıtma işlemi öngörülmemiştir. Dolayısıyla,çimento bağlı sıradan ürünlerde ısıtma sırasında meydana gelen sorunlar burada yaşanmaz.

- Malzemenin hidrolik bağlı malzemelere kıyasla çok daha yüksek olan dayanıklılığı sayesinde eritilen malzeme miktarına bağlı refrakter malzeme giderleri de düşürülebilir.

Quick repair in aluminium industry - Aluminyum Endüstrisinde hızlı Onarım çözümleri

In our hurried world the continuous availability of means of production is very important. Therefore the demand of our customers to work without their melting and soaking furnace as short as possible in case of a small damage is understandable. Our experts worked out a new technology, which makes the repair of certain smaller damages of melting and soaking furnaces during a weekend possible. The quick repair can be executed by using a new chemical bonded aluminium repellent refractory material. When repair is completed, the setting time is 3-4 hours, then the shuttering can be removed, and the heating up can be started immediately.

 People should not wait 24 hours for the final forming of hydraulic setting, as in case of cement bonded products.

Heating up speed of furnaces repaired with AUFLOW-80 AL can be 120 ^oC / hour, therefore, by using this material the furnace can be placed back to production in 12-24 hours after the repair instead of the usual 3-5 days heating up.

Knowledge base - Temel Bilgiler

• What is refractory material?
• Grouping of refractory materials
• Refractory, heat-insulating materials
• Properties of refractory materials

What is refractory material?

Every material, which has the melting point over 1500 °C, is called refractory material.
Analysing from another aspect, every material, which has the service temperature over 900 °C, is called refractory material. Materials used below this temperature are called heat-resisting materials.
According to a less accurate wording we call every material refractory, which permanently resists the varied requisitions in an industry furnace on high temperature without significant change. It suggests that refractory materials have to sustain not only high temperature, but loads coming from dead-weight, abrasive and chemical effects when built in structures.

Grouping of refractory materials

Refractory materials can be grouped according to various aspects:

- Chemical composition

• Silica products (silica bricks and mortars)
• Aluminium-silica products (fire-bricks, high alumina bricks, concretes, and mortars)
• Basic products (basic bricks and basic masses)
• Carbonic products
• Silicon-carbide (SiC) products
• Zirconia products
• Special products (oxide and non-oxide, BN3)

- Refractoriness

• Refractory (SK18-35)
• High refractoriness (SK36-42)
• Very high refractoriness (over SK42)

- Porosity

• High density (0-16%)
• Dense (16-30%)
• Light (30-75%)

- Production technology

• Shaped refractory materials (refractory bricks and forms)
• Non-shaped refractory materials (refractory concretes, refractory mortars, refractory glues, etc.)

Refractory, heat-insulating materials

Refractory, heat-insulating materials have significantly less bulk density (~0,4-1,6 g / cm3) and higher porosity (~45-80 tf%) than traditional dense refractory materials, and accordingly the coefficient of thermal conductivity is much less.

Can be grouped according to production technology:

• with blowing additive
• with foaming
• with gas generation
• with volatile

material.
These are very often combined.

According to outer form we differentiate:

• Shaped (pressed, drawn, cast, vacuum formed)
• Non-shaped

Refractory, heat-insulating materials can be:

• Ceramic fibre, rock cotton insulating materials
• Calcium silicate materials
• Micro-porous insulating materials (WDS)
• Insulating bricks

Properties of refractory materials

Refractoriness

Refractoriness of refractory material is the temperature, at which the truncate cone shaped sample made of the refractory material curves under its own weight so, that the top of cone reaches its bottom.
Refractory materials are usually made of more components having varying melting points, so there is no definite melting point. The component having the lowest melting point melts on high temperature, and when the quantity and viscosity of the melt exceeds a certain critical value, it distorts under its own weight, and loses its structural stability.
Value of refractoriness is not identical with the service temperature.
Marking: SK (Seger cone) – this is more common
or PK (pyrometric cone)

Chemical composition

Usually we study the Al2O3, TiO2, SiO2, Fe2O3, CaO, MgO, Na2O+K2O, Cr2O3 content of refractory materials. Depending on the type of refractory material we study other components, too; for example SiC, BaO.
Unit: %

Bulk density

Bulk density is the ratio of the weight of refractory material and the volume measured with pores.
Unit: g/cm3, kg/dm3, t/m3

Hydration

The hydrating ability of refractory materials shows that during impregnation of open pores how much water is hydrated compared to the dry mass of the sample.
Unit: %

Porosity

Refractory materials are usually not gas-compact, as these contain smaller, larger closed or open pores.
- Open or apparent porosity is the ratio of the volume of open pores to the total volume of the sample, including the volume of pores.
- Complete porosity is the ratio of total volume of pores to total volume of the sample, including the volume of pores.
Unit: %

Strength

In the most cases the strength of refractory material to be applied has quite an important role, as sometimes this is the most important figure.
Usually the compression strength is studied, but to measure the bending- or tearing strength could be necessary, where it is needed.
The compression strength is the resistance of refractory material to compressive stress.
It could be cold compression strength, or hot compression strength.
Unit: kp/cm2; N/mm2; Mpa
Softening under load

The built-in refractory materials are exposed to various pressures during working. The weight of lining gives compressive stress, but shear, and bending stress may occur, too. So, the softening under load is an important data considering the application.
Softening under load is typical of behaviour of refractory material during usage, and gives the highest temperature of usage.
Unit: °C

Secondary shrinkage, growth

Secondary volume changes of partly burnt or unburnt refractory materials occur on high temperature.
Its numeric value is the percentage of change related to pre-heating, original length, and volume.
Maximal service temperature is the temperature, at which the value of linear secondary shrinkage reaches 1,5%.
Unit: %

Thermal expansion

During a furnace building it is important to know the thermal expansion of the refractory materials used to calculate the dilation (expansion) joints.
Usually the linear thermal expansion is determined in the percentage of original length.
Its value varies depending on the temperature, so the thermal expansion factor is referred to a certain temperature, or range of temperature.
Unit: %
Besides, there is cubical expansion as well.

Resistance against temperature change
(thermal shock resistance, chilling, abschreck)

The effect of temperature changes is that crackles may occur on the refractory bricks. The reason for this is the significant quantity of glassy phase in the bricks, inside pressure, phase changes occurring during burning.
We express the resistance against temperature change with a heat variation (chilling) number, which shows, that how many times the studied refractory material stood the heating and cooling, until the 50% of area exposed to heat variation started cracking.
Unit: number of cycles

Thermal conductivity

Refractory materials are not insulating perfectly, and let the some heat through. We call this property thermal conductivity. It depends also on the temperature of the refractory material.
Unit: W/mK

Relative density

Relative density is the ratio of weight and volume of powdered, dried, pore-free refractory material.
Unit: kg/dm3, g/cm3
Heat capacity

Heat capacity is the heat quantity, which increases the temperature of a unit of refractory material by 1°C. Its numeric value depends on the temperature.
Unit: kJ/kg0C

Gas permeability

Gas permeability is the property of porous refractory material, which lets air, or gas through as an effect of pressure difference. It shows the kind of porosity of material (pore dimension, pore spreading).
The gas permeability coefficient is perm, marked: Pm
The material has 1 Pm gas permeability coefficient, if during 1 second 1 cm3, 1 poise viscosity gas flows through 1 cm2 surface of the 1 cm long test sample as an effect of 1 dm/cm2 pressure difference.
The gas permeability decreases while the temperature increases, as the viscosity of gases is increasing.

Slagging

The slagging of refractory materials is very important especially for furnace linings contacting the melts.
The kinds of slag effect are so various, and the composition, viscosity and circulation circumstances of the slag are so different, that reproducing among laboratory conditions is not, or quite limitedly possible.
The most common test method is the so-called jar-method: we make a 50 mm hole into the test sample, we place the corrosion agent (glass, slag, etc.) in. Then we heat the test sample in a furnace on given temperature. After cooling down, we cut the test sample and we determine the extent of scouring and infiltration.

Solubility (in acids, alkalis)

Special kind of refractory material is the acid-proof material.
Acid-proof refractory materials resist the chemical effects of acid gases, acid fluid and alkalis. The mix of concentrated vitriolic acid and concentrated nitric acid is used for testing the acid-proof materials.
The numeric value of solubility is determined by the per cent weight reduction occurring after solvent effect in proper circumstances.

Electric resistance and conductivity

Refractory materials are not conductive on normal temperature, so their resistance is quite large. However, if the temperature is increased, the resistance will decrease and some refractory materials become semiconductor over 1000 °C. Conductivity is significantly influenced by contaminations, especially the iron-contaminations are damaging.

Deformation under permanent load (creep)

Refractory materials, which get significant load during use besides the temperature, may specially deform.
The reason is that in refractory materials melt-phase is forming on 1000-1100 °C, and its viscosity and quantity, as well as the quantity, dimension, form of grains and pores determines the rheological (flowing, deformation) properties of the material.
The creep of built-in refractory materials is generated by slag- or glass melt, or flue dust. The properties of built-in materials are changing as an effect of melt or flue dust. Materials may show 10-20% deformation under quite small load compared to the original size. The creep is going quite slowly, on especially low temperature. This process doesn’t stop, and continues upon permanent load by almost constant speed.

Abrasion resistance

The abrasion of built-in refractory material can happen variously: dissolution in slag-, or iron melt, cracking, slacking by gas or other agents and mechanical abrasion. The latest occurs when the lining on quite low temperature (600-1200 °C) is exposed to some abrasive effect (e.g.: shaft furnace).
