Zhiyao refractory high alumina refractory bricks are aluminum silicate refractory bricks with an Al2O3 content of not less than 55%. According to the different grades of bauxite clinker used, different quality requirements, and the choice of formula binding agent, the appropriate ratio Distributed and calcined after molding using a brick press.

According to the different grades of bauxite clinker used, different quality requirements, and the choice of formula binding agent, the appropriate ratio Distributed and calcined after molding using a brick press.
The raw material content of the Shanxi inverted kiln is 192% of the Yang, 80% of the chemical raw materials are matured, primitive-rich, beautiful in appearance, the mouth is blue-black, khaki, and blue dust. The combustion is sufficient, and it is an ideal raw material to produce DL-80 and DL-75 high alumina bricks on the top of electric furnaces.
In the past, huge manufacturers of refractory bricks produced 20-30% of the top bricks used in electric furnaces due to the lack of fire due to the low fire volume of the earth and soil clinker produced by the shaft furnace. The raw materials are matched with the production of general bricks, or they produce an unshaped refractory ground powder. Use, waste materials, and can’t make full use of them. Because-the main solid phase of alumina clinker is corundum and moss. Therefore, we have adopted the inverted flame kiln resource to be finely burned to make it have a good structure, which has a good foundation for mass production of electric furnace top bricks, blast furnace bricks, etc., and creates favorable conditions for exporting foreign exchange.
The company is a comprehensive enterprise integrating scientific research, production, engineering design, kiln construction, and support services. The company mainly produces and sells steel, glass, cement, lime, calcium carbide, coking, carbon, electrolytic aluminum, boilers, and garbage incinerators. , Metal magnesium, chemical, and other kiln supporting projects with shaped and unshaped refractory materials.
