Introduction
Changyi alumia magnesia spinel carbon brick takes the alumia magnesia spinel, corudum or fused magnesia as raw materials, caring the aggrandizement of matrix and being shaped by the high pressure, which has characteristics of anti-erosion, high strength of high temperature, and fine thermal stability, suitable for the bottom and wall of molten steel container.
