无碳钢包砖在汉钢公司的应用实践

Application Practice of Non-carbon Steel Ladle Brick in the Steel Plant of Hansteel Company

主要讲述了汉钢公司炼钢厂将150 t钢包砖由镁碳质改选为无碳质,并采用综合砌筑的方式。经过两年多的生产实践,取得良好的使用效果,平均包龄提高了约90炉,最高达200炉次,完全可以满足于含碳量要求不太严格的钢种。无碳钢包砖的应用不仅降低了吨钢耐材、煤气成本,而且为新钢种的开发奠定了基础。

The150 t ladle brick by Mg O-C steelworks of Hansteel Company is substituted by no-carbon, combined with comprehensive masonry, after more than two years of practice, a good effect has been achieved. The average age of the package is increased by about 90 furnace and up to 200 times, which can be fully satisfied with the steel with less stringent carbon content. Application of non-carbon ladle brick not only reduces the cost of per ton of refractory, gas, but also lays the foundation for the development of new steel.
