Q: Common bond brick?
Lime should contain a lot of active CaO, I decompose CaCO3 and MgCO3 not more than 5%, Al2O3+Fe2O3+SiO2 no more than 5%. When the content of large particles, burned Ca-CO3 and over burned lime, the product produced caves, affecting the quality of products.
Q: Why will expand when heated brick
After high temperature after the formation of tridymite and cristobalite and quartz and a small amount of residual glass phase, quartz heating to 220-240 DEG C, in a certain degree of thermal expansion, brick maximum expansion occurs in 100~300 DEG C, 300 expansion before the total amount of expansion is about 70%~75%.
Q: The specific content is what gb/t2608-2012 brick
The provisions of the brick classification, technical requirements, test methods,
Q: Why is the new trend of the high thermal conductivity of silica brick
The use of high thermal conductivity of silica brick, reducing coke fuel consumption, reduce emissions of pollutants such as NOx, with considerable economic benefits and social benefits, is the future direction of the new technology of using coke oven refractory.
Q: Such purpose and scope please give me detailed points thank you because I am learning stage
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 high thermal conductivity of silica brick and traditional brick what is the difference?
The scale quartz is a spear shaped double crystal structure, very compact and favorable to the increase of thermal conductivity. The high thermal conductivity of silica brick in improving thermal conductivity and other performance indicators and traditional coke silicabrick agreement.That is to say, the high thermal conductivity of silica brick all inherited the traditional advantages of coke oven silica brick, on the basis of further highlight the characteristics of high thermal conductivity
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
Q: Why in the production of the brick to detect the volume density
Fast density test, please consult an instrument.
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: Physical solid waste disposal
Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products when firing, reduce cracks, improve the rate of finished products.
