1000The introduction of brown corundum brick ：
Brown corundum brick is a kind of refractory brick, with corundum (brown corundum, subwhite corundum, dense corundum, etc.), silicon carbide as the main raw materials, adding special additives to mix, using high pressure molding, after high temperature firing, fine grinding and pre-assembly product. It has the characteristics of low corrosion resistance to slag and iron, good alkali corrosion resistance, etc. It is suitable for the furnace bottom, hearth ceramic masonry, tuyere, iron mouth, slag mouth and other parts of blast furnaces of different volumes.
Production process and application of brown corundum refractory brick:
The composite brown corundum brick is made of bauxite and coke (anthracite) as the main raw materials, and is smelted at a high temperature of 2000 degrees in an electric arc furnace. The hardness is HV1800-2200, and the toughness is higher than that of SIC. The abrasive tool made of brown corundum is suitable for grinding metals with high tensile strength, such as various general steels, malleable cast iron, hard bronze, etc. It can also be used to manufacture brown corundum bricks. A high-grade refractory material.
The advantages and characteristics of brown corundum refractory bricks:
1. The corrosion rate of slag and iron is low.
2. Strong resistance to molten iron and alkaline slag erosion.
3. It is resistant to molten iron erosion and has strong self-repairing ability.
4. Long service life.

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
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%.
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
High alumina brick is mainly used for lining of blast furnace, hot blast furnace, electric furnace roof, reverberatory furnace and rotary kiln. In addition, high alumina brick also widely used as open hearth regenerative lattice brick, pouring system with plug,such as nozzle brick.
Anchor bricks are anchor bricks for industrial kilns. The electric furnace roof is a furnace roof structure supported by metal hanging bricks and refractory bricks. Therefore, the leakage of reactive gas and hot gas in the furnace will damage the metal hanging parts, thereby causing furnace damage. roof collapse accident. Anchor bricks are also called hanging bricks and anchors.
Refractory wet mud used to block the iron outlet can be divided into two categories: water cannon mud and waterless gun mud. On large and medium -sized blast furnaces on high top pressure and high degree of smelting.
