随着炼钢工艺的发展,对耐火材料的要求亦日趋严格。为了提高转炉炉衬寿命,降低耐火材料消耗,七十年代中期发展了抗渣性强、耐冲刷、热震性好的镁碳砖。本文叙述了美、日、西德等国镁碳砖的主要性能及在生产中应用的效果,为鞍钢采用这种新型耐火材料起到一定作用。 With the development of steelmaking technology, the requirements for refractory materials are also becoming more stringent. In order to improve the lining life of the converter and reduce the consumption of refractory materials, magnesia carbon bricks with strong slag resistance, erosion resistance and good thermal shock resistance were developed in the mid-1970s. This paper describes the main properties of magnesia-carbon brick in the United States, Japan and West Germany and its application in production. It plays a role for Ansteel to adopt this new refractory material.
