Q:Why is the three oxidation of two silicon is very harmful impurities in silica brick
Can generate the material needs is the best way to see the impurity problem!! the first consideration is whether can get the material impurities with what method choice after the time! Miscellaneous reactions cannot have new impurity formation! Selected cannot and need material reaction reagent!
Q: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: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: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
The amount of addition is related to the shape and weight of the brick. The bricks can be added to 20% weight less than 25kg; bricks above 25kg can be added to 30%; for the specific type of brick can be added 30%. into waste silica brick should pay attention to this problem
Q:Can not use it two brick
Acidic silica brick refractory material, has good ability in acid slag erosion
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:High temperature refractory material?
Basic refractories in Magnesium Oxide and calcium oxide as the main component, the main products are magnesia brick, magnesia chrome brick, magnesia zirconia brick, magnesia brick, magnesia spinel brick, magnesia calcium brick, dolomite brick and the latest development of magnesia spinel brick and so on. With Magnesium Oxide (MgO) more than 80% of the refractory brick called magnesia brick,
Q:What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you
The main damage of silicon carbide side wall brick is stress damage, not chemical erosion. Chemical damage is formed prior to the formation of the groove, and the damage to the chemical erosion is little after the formation of the groove.
Q:Semisilica brick, clay brick, high alumina brick and what is the difference?
The share of A12O3 and SiO2 is different
