General Information

The CMAX super-duty silica bricks for glass melting tank is characterized by high purity, less impurity, good corrosion resistance, higher bulk density, complete phase transformation, lower residual quartz, high RUL, lower thermal expansion and stable volume at high temperature. This leads to increase in service life of glass furnace and reduction in energy consumption. These products have found wide application in crown and key areas and been highly appreciated by clients.

 

Feature

CMAX Silica bricks produced by CNBM are characterized by smaller density, good thermal shock resistance, lower thermal conductivity, high RUL and good insulating performance.

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: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: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: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:The specific content is what gb/t2608-2012 brick
Quality assessment procedures, packaging, marking, transport, storage, and quality certificates. Suitable for siliceous refractory bricks.
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:What is the main material of silica brick
An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.
Q:Why will expand when heated brick
Because the production of raw materials are silica brick, brick with SiO2 content of not less than 95% of silica as raw materials, adding mineralizer and binder, through mixing, molding, drying, sintering and other processes in the system
Q:What are the main constituents of refractory bricks?
Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon, aluminum, clay and so on:
Q:Glass kiln brick for physical and chemical indicators?
Glass kiln with high quality silica brick with silicon oxide content, low melt index, mainly used for glass kiln crown, parapet, wall hanging, small furnace arch superstructure and regenerator.
