What refractory bricks should be used in each part of a blast furnace

Description: Blast furnace is a large high temperature metallurgical furnace for smelting molten iron from coke reduced iron ore. The furnace lining of different heights of the temperature, pressure, physical and chemical nature of the change, the severity of working conditions are different, so the lining damage mechanism, damage condition is also different, the selection…

magnesia-aluminum brick

Application of different magnesia-alumina bricks in kilns

Description: Magnesia alumina bricks include ordinary magnesia alumina bricks, magnesia alumina spinel bricks and modified magnesia alumina spinel bricks. In the firing process of magnesia alumina bricks, MgO and Al203 react at high temperatures to form a high temperature mineral phase of magnesia alumina spinel (MgO·Al203). Magnesium-aluminum spinel has a small thermal expansion coefficient and…
