New type of building materials "basic refractories" (Magnesium Oxide, light burned magnesia, etc.) magnesium chloride.

Alkaline refractories mainly refer to refractories with light burned magnesia balls and light burned magnesia powder, which have strong corrosion resistance to alkaline slag.

The commonly used is the magnesium ball. The magnesia ball containing more than 80% to 85% of Magnesium Oxide has good resistance to alkaline slag and iron slag, and its refractoriness is higher than clay brick and silica brick. It is mainly used for open hearth, oxygen converter, electric furnace, non-ferrous metal smelting equipment and some high temperature equipment.

Characteristics of alkaline refractories

The refractory is more than 1580 centigrade inorganic nonmetallic materials. Refractoriness magnesium chloride refers to the centigrade temperature of the refractories cone specimen that does not soften and melt under the condition of no load. Refractories come together with high temperature technology, which originated in the middle of the bronze age. China's Eastern Han Dynasty has used clay refractories as kiln materials and casket for firing porcelain. At the beginning of twentieth Century, refractory materials developed towards high purity, high density and ultra high temperature products. At the same time, unshaped refractory and refractory fiber, which did not need to be burned and had small energy consumption, appeared. In modern times, with the development of atomic energy technology, space technology and new energy technology, the refractory materials with high temperature resistance, corrosion resistance, anti hot vibration and scour resistance have been applied.
