Q:What is the silica refractory products?

Refractory brick with silica content greater than 90%.

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.

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:The specific content is what gb/t2608-2012 brick

The provisions of the brick classification, technical requirements, test methods,

Q:The difference between clay refractory bricks and refractory brick in the application.

The ability of alkali resistance is poor, the thermal shock stability is the worst, and it is scrapped at one time. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.

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 introduction of silica brick

The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass

Q:The brick is mainly used in the place?

Partitions used in coking and combustion chambers for coke ovens

Q:What role does silica play in refractories?

Low fractory refers to the alumina content between 10%~30%, SiO2 content is less than 85%, semisilica brick SiO2 = 65%,The SiO2 content of not less than 93%, refractory material to natural quartz rock as the main raw materials are called silica, silica brick, silica brick, quartz glass and special products. China's literature generally put this type of product is called "siliceous refractory products", which is the most important brick.
