Silimanite Brick

General Information of Silimanite Brick

Silimanite bricks use silimanite raw materials. The silimanite bricks have around 60% alumina content and low iron content. It offer better CO-resistant properties. And nonstandard shapes could do under customers request.

Characteristics of Silimanite Brick

Compared with the high alumina bricks, silimanite bricks have the better characteristics:

High tensile strength

Strong resistance to crossion

Thermal shock resistant

Typical Application of Silimanite Brick

The silimanite bricks could be used in the steel and non-ferrous metals industry, which are in direct contact with liquid metal are possible. The sillimanite bricks are good for refractory solutions in the glass industry, cement industry and incineration, for industrial processes with rapid thermal shocks, in furnaces for firing biomass and in production kilns of the ceramic and refractory industry.

silimanite brick furnace

Q:Is it good for your cupola to use that kind of refractory, high aluminum brick, clay brick or red silica?: The high aluminum clay brick is slightly more stable and can be used!

Q:I am a student of refractory materials. I would like to know the general rank of national refractory materials company: Zhejiang Sunon Refractories Co., Ltd. is a group member of the factory of industrial economy research China (country), building materials building materials industry center Changxin Branch Center of refractories. The main products are: wear-resistant refractory brick, aluminum silicate fiber board, ordinary magnesia, heavy casting materials, spalling brick kilns, special casting materials, high strength and abrasion resistant castable refractory castable, special pulverized coal burner, MF-170 coating (with fabric), clay brick, corundum wear-resistant plastic, calcium silicate board, lightweight castable and the direct combination of magnesia chrome brick, unburned magnesia chrome brick, anti flaking high alumina brick, mullite brick, antiskinning castable,

Q:What refractory materials are adopted in each part of the blast furnace?: The furnace throat is a part of the direct impact and friction when the burden drops, and the high density and high alumina brick is usually adopted. The upper and middle shaft temperature is only 400~800 degrees, the parts with high alumina brick and sillimanite brick. The lower part of the shaft due to high temperature and dust by scouring and alkali metal vapor erosion, so the requirements for the slag resistance, alkali resistance and high temperature resistance, wear resistance of high quality clay brick, high alumina brick, carborundum brick or corundum brick. Belly temperature reaches 1400~1600, and slag, steam erosion, erosion and corrosion is strong, therefore, the silicon carbide reaction bonded silicon carbide brick.

Q:Sillimanite brick: After calcination at high temperature, sillimanite transforms to mullite and free silica. Generally use the firing process and production of high temperature mud casting method. Its physical and chemical properties are better than those of aluminum bricks, the refractoriness is 1770~1830 degrees, and the load softening point is 1500~1650 degrees centigrade. The utility model is mainly used for the forming of a liquid hole in a glass furnace, a lining of a blast furnace, a furnace throat and a ceramic industrial kiln tool.

Q:What kind of refractory material will be used in the glass kiln?: 2. dense zirconia brickHigh temperature & glass corrosion performance of the brick is slightly lower than that of chromium oxide, also by isostatic pressing forming method, its technical indicators ZrO2>65%, <2.0% porosity, volume density of about 4.25g/cm3, the temperature in E glass is higher than 1370 DEG C have erosion. Used in the E glass melting pool unit kiln glass temperature slightly lower at the end of the transition path, forming the bottom of the pool and forming path path flow tank and bushing support brick etc.. In addition, the dense zirconia brick is used as the backing brick of the dense chrome brick.
