Chrome corundum brick refers to corundum refractory products containing Cr2O3. At high temperature, Cr2O3 and Al2O3 form a continuous solid solution, so the high temperature performance of chromium corundum products is better than that of pure corundum products. Chromium corundum products are widely used, and the content of Cr2O3 is mostly in the range of 9% to 15%.
Corundum bricks are mainly used in iron-making blast furnaces and blast furnace hot blast furnaces, refining furnaces outside steel-making furnaces, sliding water heaters, glass melting furnaces and petrochemical industrial furnaces, etc.
The heavy part of the raw materials for the chrome zirconium corundum composite brick is sintered tabular corundum, high-purity chromium oxide, high-purity zircon, and Guangxi white cement.As the main raw material, the light part of the raw material is made of 47 mullite, kyanite, floating beads and coke gemstones as the main raw materials. During molding, a separator is set in the middle of the mold, and heavy materials and light materials are added at both ends. After high pressure molding , finished products made of high temperature sintering.
The heavy parts of the chrome-zirconium mullite composite bricks are made of high-purity sintered mullite, high-purity chromium oxide, high-purity zirconia, and Guangbai mud as the main raw materials, and the light part of the raw materials are made of 47 mullite, kyanite, Bleaching beads, coke gemstones and Guangxi white mud are the main raw materials
Brown corundum refractory brick is made of fused corundum as the main raw material. It is formed by high pressure and fired at high temperature. It has high thermal shock stability, low porosity, low expansion, good resistance to melt vapor and gas erosion, and excellent oxidation resistance. Dimensionally accurate advantages.
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.
Magnesia chrome bricks are refractory products with magnesia (MgO) and chromium trioxide (Cr2O3) as the main components, and periclase and spinel as the main mineral components. The main raw materials for the manufacture of magnesia-chrome bricks are sintered magnesia and chromite.
Corundum self flowing castable is a high-tech product developed according to the theory of solid fluid and combined with the application characteristics of refractory materials, which is the first in China. The corundum self-flowing material can be degassed and leveled without vibration with the help of its own gravity, so as to achieve densification.
Silica brick is an acidic refractory mainly composed of tridymite, cristobalite and a small amount of residual quartz and glass phases
