钢包用轻重质复合保温砖的研究与开发

Investigation and development of light and heavy composite insulating brick for refining ladle

精炼钢包永久衬用轻重质复合保温砖的重质部分相当于高铝砖，轻质部分相当于粘土质隔热砖。实际使用表明，采用轻重质复合保温砖作钢包永久衬，节能效果明显．可以获得显著的社会经济效益。

Light and heavy composite insulating brick used in permanent lining of refining ladle is composed of two parts.The heavy part is equal to high alumina brick and the light part is of fireclay insulating brick. Using this kind of brick in the permanent lining of the refining ladle has gained remarkable energy saving result.
