Q:What role does silica play in refractories?
The production of clay brick refractory clay raw material is natural, its main mineral is kaolinite (formula Al2O3 - 2SiO2 - 2H2O), clay brick containing SiO2 in 45% ~ 65%, belongs to the weak acid refractory materials, have a certain ability to resist acid slag, but easy to be alkaline slag erosion.
Q:The hot blast stove when the temperature did not rise against the brick interface decreased
Insulation of hot blast stove, key insulation silica brick hot stove, hot blast stove is shutdown or need repairing in blast furnace.
Q:The brick is mainly used in the place?
Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.
Q:Common bond brick?
When adding ingredients, the amount of lime added shall be converted to CaO, and the amount of addition varies depending on the product, usually fluctuating at 1.5~2.5%. For example, the production of coke oven silica brick, the dosage of CaO is 2.0~3.0%; the production of electric furnace top brick, the dosage of CaO is 1.4~1.75%.
Q:The production of brick, the ingredients of why join the waste brick
Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.
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:Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450
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.
Q:High temperature refractory material?
Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, the refractory material used for special occasions.Now the definition of refractory materials, has not only depends on whether the refractoriness at 1580 DEG. Refers to the current refractories used in metallurgy, petrochemical, cement, ceramics and other production equipment with inorganic non-metallic materials.
Q:Semisilica brick interpretation
High temperature volume stability. Volume change is small.
Q:The difference between clay refractory bricks and refractory brick in the application??
Brick bearing soft temperature and close to the melting point, high temperature strength, can be in high temperature (above 1400 degrees) under the condition of long-term use,
