High alumina refractory bricks are the backbone of high-temperature industrial processes. By understanding their properties, applications, and supplier selection criteria, businesses can enhance operational efficiency and reduce downtime. For industries seeking durable, cost-effective solutions, partnering with certified refractory materials suppliers in China ensures access to cutting-edge technology and reliable supply chains.
The Al2O3 content of clay heat Clay insulating refractory bricks is generally more than 40%, and the Fe2O3 content is less than 2.0-2.5%. The clinker in the ingredients is 65-85%, and the combined clay is 35-15%. The crushed bonded clay and the finely ground clinker are mixed and milled, and then mixed with the granular clinker to make semi-dry mud, high pressure molding, and sintering at about 1400 ℃, with good performance.
low porosity clay bricks are mainly used in the regenerators of glass kilns. They can also be used in blast furnaces and hot blast furnaces in the steel industry; cement kilns in the building materials industry; chemical kilns in the chemical industry as kiln linings
Refractory castable is a kind of refractory material that does not need to be formed and has good fluidity after being fired and stirred with water.
Silica brick: an acidic refractory mainly composed of tridymite, cristobalite and a small amount of residual quartz and glass phases. Its silica content is more than 94%, it has anti-acid slag erosion performance, high high temperature strength, high load softening temperature, long-term use in high temperature flower wells without deformation, but low thermal shock stability (heat exchange in water is 1-4 Second-rate).
Silicon carbide castables mainly use 98 silicon carbide as the main raw material, add water reducing agent and micropowder, and use pure calcium aluminate cement as binder to make amorphous refractory materials. Cupola and other high temperature materials to be recorded.
