Q:How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?
Mainly depends on the color and density of brick. Another black clay brick and brick with iron oxide formation and how much the size of bricks
Q:Can not use it two brick
The softening temperature is up to 1640~1670 DEG C, and the volume is stable at high temperature for a long time.
Q:The specific content is what gb/t2608-2012 brick
The provisions of the brick classification, technical requirements, test methods,
Q:The introduction of silica brick
Acidic silica brick refractory material, has good acid resistance and slag erosion, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature.
Q:Such purpose and scope please give me detailed points thank you
Mainly used for coke oven carbonization chamber and the combustion chamber wall, open hearth furnace regenerator and a sediment chamber, soaking furnace, glass furnace, refractory materials and ceramic brick kiln, kiln vault and other load-bearing parts. Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.
Q:The difference between clay refractory bricks and refractory brick in the application.
Clay brick features good thermal shock resistance and low price, but high temperature performance is not well integrated, and the long-term use temperature is not higher than 1300 degrees. It is widely used in low temperature parts of various kilns.
Q:Semisilica brick interpretation
Good thermal shock resistance. In use, more high viscosity glass phase can be formed, and the masonry brick joint and the working surface are dense and the masonry is complete, which is beneficial to improve the impermeability of the masonry and reduce the erosion effect of the slag on the masonry.
Q:The introduction of silica brick?
The characteristics of silica brick:Brick belongs to refractory materials, with strong resistance to acid slag or acid solution erosion ability, high load softening temperature are excellent properties of silica brick, usually 1640-1680 C.The use of silica brick:Mainly used for masonry brick oven carbonization chamber, a combustion chamber and a partition wall, glass furnace and kiln roof, pool wall, high temperature hot blast furnace, glass furnace, load-bearing pool wall, hot blast stove, baking furnace of carbon bearing part of high temperature furnaces etc.. Rongsheng with refractory
Q:The difference between clay refractory bricks and refractory brick in the application??
The ability of alkali resistance is poor, the thermal shock stability is the worst, and it is scrapped at one time. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.
Q:How to improve the thermal conductivity of the coke silicabrick rate?
The content of SiO2 is 98.23% crystalline silica as raw material, with sulfite pulp liquid as binder, millscale and lime as mineralizer, by Jin Hongshi (TiO2) as additive, can improve the rate of thermal conductivity of silica brick for coke oven. When the rutile content is 1.5%, the coefficient of thermal conductivity of silica brick for coke oven is 2.66W/ (m.k).
