Silica brick is mainly used for Coke oven, glass kiln, hot-blast stove, tunnel kiln,Acidic furnace non-ferrous metal smelting and some other thermotechnical equipment in good furnace building materials.

$Refractory Silica Brick High Quality$

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:Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450: That is because the brick load softening point the maximum temperature is 1450 degrees.

Q:The brick is mainly used in the place?: 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.

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.

Q:The chemical composition of silica brick and its physicochemical index?: Brick refers to the refractory products in more than 93% of the content of SiO2

Q:The introduction of silica brick: An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.More than 94% silica content. True density 2.35g/cm3. With acid resistance, slag erosion performance. Higher high temperature strength. The softening start temperature is 1620~1670 degrees. Long term use at high temperature without deformation. The thermal shock resistance is low (the heat exchange in water is 1~4 times). The natural silica is used as the raw material, and a proper amount of mineralizer is used to promote the transformation of quartz into quartz in the body. Slowly sintered at 1350~1430 DEG C in the reducing atmosphere. When heating up to 1450 degrees, the total volume of 1.5~2.2% expands, and the residual expansion can close the kerf and ensure the airtight and structural strength of the masonry.

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:What is the silica refractory products?: Refractory brick with silica content greater than 90%.

Q:Common bond brick?: When adding ingredients, the amount of lime added shall be converted to CaO, and the amount of addition varies depending on the product, usually fluctuating at 1.5~2.5%. For example, the production of coke oven silica brick, the dosage of CaO is 2.0~3.0%; the production of electric furnace top brick, the dosage of CaO is 1.4~1.75%.

Q:Can not use it two brick: Acidic silica brick refractory material, has good ability in acid slag erosion
