Alkaline refractory materials mainly refers to the oxidation of magnesium, calcium oxide as the main component of the refractory, the alkaline slag has a strong anti – erosion ability. Including 
magnesia brick, magnesia brick, magnesia chrome brick, dolomite brick (see magnesia brick).
magnesia brick, magnesia brick, magnesia chrome brick, dolomite brick (see magnesia brick).
Commonly used is brick. Containing magnesium oxide 80% ~ 85% of magnesia brick, on the basic slag and iron slag has good resistance, refractoriness than clay brick and brick. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment.
Characteristics of basic refractory materials
Inorganic non metallic materials with fire resistance higher than 1580. Refractoriness refractory cone specimen under no load, resistance to high temperature and not softening melting down
Celsius temperature. Refractory materials and high temperature technology, which originated in the middle of the Bronze Age. In the Eastern Han Dynasty has made China kiln firing porcelain material and with fireclay refractory sager. At the beginning of twentieth Century, the refractory materials were developed in the direction of high purity, high density and ultra high temperature, and there was no need to burn, and the energy consumption is small. Modern, with the atomic energy technology, space technology, new energy technology development, with high temperature resistance, corrosion resistance, thermal shock resistant, resistant refractory material erosion comprehensive excellent performance has been applied.
