230*114*65mm High refractoriness Magnesite brciks for steel-making furnaces
Desctiption
Magnesia firebrick is alkaline refractory product that made of high grade megnesia molding by high temperature, the main crystalline phase is calcite, it is with properties of high refractoriness, good anti-alkaline slag performance, high refractoriness under load, but the thermal shock resistance is a little week.
Application:
Magnesia firebrick is mainly used in steel-making alkaline open hearth furnace, electric furnace bottom and furnace wall, converter permanent layer, metal mixer working layer, non-ferrous metal smelting furnace, high temperature tunnel kiln, cement rotary kiln lining, glass furnace regenerative chamber checker brick etc.
