Q:Common bond brick?
Manufacturing for silica brick binder hi-li sulfate pulp waste liquid and lime milk. When lime milk is used as a bond, it acts as a plasticizer. To increase the strength of lime brick in the drying process, as mineralizer in the firing, promote the transformation of quartz.
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 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 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: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:Such purpose and scope please give me detailed points thank you because I am learning stage
Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.
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, but the anti alkali erosion ability, thermal shock stability is the worst, a scrap. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.
Q:How much is the highest melting point of silicon?
Acidic silica brick refractories, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature. More than 94% silica content.
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:Why is the three oxidation of two silicon is very harmful impurities in silica brick
Heating calcination is the best way to extend this sort of impurity removal. Remove impurities
