It is predicted that the average annual consumption per ton of steel refractory in the next five years will decrease by about 0.5 to 1.0 kg. By 2005, the single consumption per ton of steel refractory in my country's iron and steel industry will drop to 28 kg. Cal··· ...

The magnesia-aluminum spinel in the magnesia-aluminum spinel brick is a general term for minerals with the same crystalline structure as the mineral name. Generally, spinel refers to MgAl2O4 or MgO·Al2O3 of common structure, that is, magnesia-aluminum spinel (MA). Ma··· ...

Product introduction: also known as siliceous insulation brick. Lightweight refractory material with silicon dioxide above 91% and bulk density below 1.2g/cm3. The refractoriness and softening temperature under load are not much different from ordinary silica bricks w··· ...

Lightweight fire brickis a kind of thermal insulation refractory material, which refers to the fire brickwith high porosity, low bulk density and low thermal conductivity. Lightweight fire bricks are characterized by a porous structure (the porosity is generally 40-85··· ...

High alumina fire brick is a neutral refractory material with alumina content exceeding 48%. It is formed and calcined from bauxite or other raw materials with high aluminum content. Above 1770 has high thermal stability and fire resistance.High alumina fire brick Usa··· ...

High alumina brick is a kind of refractory material, in which the content of Al2O3 reaches 55%~75%, and the refractoriness is above 1770℃. The refractoriness of high alumina bricks is higher than that of clay bricks and semi-silica bricks, and they belong to advanced··· ...

On June 16, 2021, a blast furnace in a steel plant was equipped with three ball-type hot blast furnaces. The hot blast temperature continued to show a downward trend, the high-alumina balls were seriously bonded, and the resistance of the pebble bed increased.1. Bondi··· ...

Alumina grinding ball Refers to the use of bauxite, roller powder, industrial alumina powder, high-temperature calcined alpha alumina powder and other materials as raw materials, through batching, grinding, powder (pulp, mud), molding, drying, firing, etc. It is produ··· ...

The fused cast azs block also called zirconia corundum brick is a white solid formed by pure alumina powder and zircon sand containing 65% zirconia and about 34% silica in the electric furnace after being melted and injected into the model for cooling. Fused zirconia ··· ...

When firing alkaline oxide-based refractory products, such as high-purity fused and re-bonded Mg0-Cr203 bricks, and special high-purity magnesia bricks with Si02 less than 1% directly bonded to MgO-Cr2O3, it is necessary to tunnel at ultra-high temperature (1800-2000 ··· ...
