Al2O3 Refractory Ramming Mass

Furnace ramming mass lining is divided in to two kinds of acidic and alkaline,But most of all the basic ramming mass lining of furnace, because of refractory materials have pH points, basic refractories in Magnesium Oxide, calcium oxide as the main component, commonly used is brick.The characteristics of basic ramming mass lining is to have enough refractoriness and softening point load.This is because in the arc under the action of different parts of the ramming mass lining of the inner surface temperature is very high, due to strong slag resistance,In the process of copper smelting slag, at high temperature through the ramming mass lining of the pore penetration in to the inside of the refractory material, melting loss, tissue caused by delamination, peeling.
In fact, basic refractory materials generally refers to Magnesium Oxide or Magnesium Oxide and calcium oxide as the main component of refractory materials.Has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio.Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature devices.The fire resistance of this kind of refractory is higher, and the ability of resisting basic slag is strong.
