采用热喷补技术是国内外提高氧气顶吹转炉炉龄的一项重要措施。我们于1977年4月正式开始对半干法热喷补技术进行实验研究工作,经两年来的实践,已基本上掌握了半干法喷补技术。喷补粘着率可达80％以上,喷补层使用寿命可达2～3炉,对于提高炉龄起到了一定作用。本文仅对鞍钢150吨大型氧气顶吹转 The use of thermal gunning technology is an important measure to raise the furnace age of oxygen top-blown converter at home and abroad. We officially started in April 1977 on the semi-dry thermal spray technology experimental research work, after two years of practice, has basically mastered the semi-dry spray technology. Spray adhesion rate of up to 80%, spray layer life of up to 2 to 3 furnaces, to improve the furnace played a role. This article only 150 tons of large-scale oxygen top-turn Angang
