Features: using high purity magnesia, synthetic quality spinels and as the main raw material,after high-pressure forming, high temperature firing of a kind of high-grade products. It not only fight infiltration capacity is good thermal shock resistance, and excellent, widely used in nonferrous industry zinc play kiln and non-ferrous metalsmelting furnace stove, and steel industry hi-temp stove.
