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.
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 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
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%.
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.
Anhydrous taphole mud/taphole clay refers to taphole mud made of tar, resin, etc. as binders and corundum, bauxite, clay, silicon carbide, coke powder, etc. as raw materials. Anhydrous carbon taphole mud is made by a mud mill. When rolling, oil is added first, then block materials (clay and asphalt), and then powder materials (coke powder and clinker powder) are added after crushing. After pressing and mixing, the mud can be produced when it meets the standards.
The high-alumina bricks are mainly used in the regenerator of the hot blast stove. The lattice bricks with a certain structure are arranged in an orderly manner, and the upper and lower through holes of the lattice bricks can allow the gas to pass through.
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.
silicon mullite brick is a kind of refractory brick product made of super high alumina bauxite and silicon carbide as raw materials through a special sintering process. It has the characteristics of continuously forming a protective layer and reducing ring formation, and its heat resistance is also very good. The softening temperature under load can reach 1600 ℃, and the service life is long. Mainly used in the transition zone, decomposition zone and cooler of small and medium-sized cement kilns.
