Date:2015-09-29 19:12 From:Zhengzhou Sunrise Refractory Author:admin


Alkaline refractory material refers to that which is easy to react with acid resistant materials, acid slag, acid flux or alumina under the high temperature. Most of the alkaline refractory materials are mainly made of magnesium oxide, calcium oxide and other alkali metal oxides. Alkaline refractory mainly contains magnesite chrome brick, magnesia zirconia brick, magnesia brick, magnesia spinel brick, magnesia calcium brick, dolomite brick and the latest development of magnesium iron spinel brick and so on.

Refractory bricks with Magnesium Oxide (MgO) containing more than 80% called magnesia brick which can be divided into many grades. Magnesia brick has good resistance to alkaline slag and slag, and has higher refractoriness than clay brick and silica brick. Magnesia brick is mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and glass industry as well as some high temperature equipment. Magnesia chrome brick has stronger resistant to alkaline slag, and the thermal shock stability is higher than that of magnesia brick, so the application is more extensive. Magnesia chrome bricks have almost replaced magnesia brick in iron and steel smelting and non-ferrous metal smelting industry. Magnesium calcium brick made from synthetic magnesia calcium sand as raw material, and calcium oxide content is generally in 15-30%, remaining components are mainly oxidized magnesium. Magnesia chrome brick is a refractory brick which is added aluminum spinel, an it is mainly used in cement industry rotary kiln, non-ferrous smelting furnace and garbage incinerator.
