Characteristics of alkaline refractories
It is represented by magnesia products. It contains Magnesium Oxide 80% to 85% above, the main crystal phase of periclase. The main raw material for the production of magnesia brick magnesite, magnesium hydroxide with seawater magnesia by the sea water extracted by high temperature calcination and etc.). Has good resistance to alkaline slag and iron slag. Magnesium Oxide pure high melting point of 2800 DEG C, therefore, the fire resistance of the magnesia brick with clay brick and brick are high. Since the mid 1950s, due to the use of oxygen converter and open hearth furnace with alkaline refractory materials, alkaline production increased gradually, clay brick and brick production in the reduced. Basic refractory material is mainly used for oxygen converter, open hearth furnace, electric furnace, non-ferrous metal smelting and high temperature thermal equipment.
