Silica Brick For Coke Oven CMAX

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: Brick refers to the content of more than 93% products SiO2. Brick with SiO2 content of not less than 96% of silica as raw materials, adding mineralizer and binder, through mixing, molding, drying, sintering and other processes in the system. The higher the content of SiO2 in silica raw material, the higher the refractoriness of the product. According to the use of brick varieties, divided into: coke oven silica brick, brick for hot blast stove, electric stove with brick, brick for glass furnaces. According to the transformation is divided into: standard bricks, tiles, bricks and general special brick etc..

Q: What is the main material of silica brickIt's common, the kind we see so often!: An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.

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: 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.

Q: The brick is mainly used in the place?: Partitions used in coking and combustion chambers for coke ovens

Q: Can iron oxide be used as refractory material?: Is widely used in this area. Mentioned refractory material of high school textbooks generally refers to three two aluminum oxide (alumina), alumina is also used as a refractory material, refractory crucible, porcelain, artificial gemstones.

Q: Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450: 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.

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: 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.
