Calcined alumina is a product obtained by calcining aluminum hydroxide at high temperature to partially or almost completely convert it into aAl2O2.
Refractory carstables for ladles is made of high-purity fused corundum as the main material, high-purity spinel is added to the matrix, and an appropriate amount of binder and admixture (dispersant, water reducing agent) are added.
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.
Common low-creep high-alumina bricks can be used in blast furnace hot blast stoves, as well as other industrial kilns, and can also be made into low-creep high-alumina bricks of different sizes according to specific construction requirements, such as lattice bricks, special-shaped bricks, anchor bricks, etc. , mainly used in industrial kilns in long-term high temperature environments
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.
Acid resistant refractory gunning material is used for spraying of blast furnaces, hot blast stoves, hot blast pipes, flue protection layers, working layers, etc.
The chemical composition of bauxite is mainly Al2O3, SiO2, Fe2O3, TO2, accounting for about 95% of the total composition, and the secondary components are CaO, MgO, K2O, Na20, S, MnO2 organic matter and trace components Ga, Ge, etc.
Special Acid-proof Brick Lightweight acid-proof Brick Acid resistant brick is the ideal choose for your project with their features of proof pressure, corrosion resistance, easy to clean and acid-base resistance.
Fireclay bricksis suitable for supporting hot blast stoves of large, medium and small blast furnaces
