- 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:Semisilica brick interpretation
- High temperature volume stability. Volume change is small.
- Q:Because of the recent relates to this industry, by way of learning to name for all raw materials, I hope knowledgeable friends exhibitions, thank you.
- Acidic materialMainly siliceous materials, such as quartz, tridymite and cristobalite, chalcedony, flint, opal, white quartzite, silica sand, diatomaceous earth, silicon oxide contained in these siliceous materials (SiO2) at least 90%, pure raw materials are silicon oxide as high as 99% or more. Siliceous materials at high temperature is the acidic nature of chemical dynamics, when the presence of metal oxide, or when in contact with the chemical reaction, and combined with a fusible silicate. Therefore, if there is a small amount of metal oxide in siliceous material, it will seriously affect its thermal resistance.
- 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: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: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:Physical solid waste disposal
- Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.
- 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:What is acid refractory?
- Refractory materials are mainly quartz glass products, combined with fused quartz products, silica brick and unshaped refractories. Semi siliceous refractory materials are generally attributed to this category. As for fireclay refractories, they are also classified as semi acidic or weakly acidic refractories. Also, zircon refractory and silicon carbide refractory for special acidic refractory materials are also classified into this category.
- Q:The brick is mainly used in the place?
- Partitions used in coking and combustion chambers for coke ovens
