目前转炉最高炉龄当数美国LTV公司(USA·LTVsteel Company·该公司有转炉2×210、2×255、2×285(CB))创下的转炉炉龄世界纪录18600炉。其工艺的主要机理是,出钢后用喷枪将氮气吹进炉内喷吹渣,把其均匀地喷镀于炉衬表面,施行挂渣作业。该技术的具体内容为美国专利。日本新日铁津君1号转炉(250t)1975年11月创下了10110炉,日本复吹转炉创下8000炉炉龄。日本一般不追求单炉炉龄有多高,而是要拿“经济炉龄”。日本钢铁界对炉龄的增加与综合炉料单耗、大修带来
The current converter maximum furnace age when the number of the United States LTV Company (USA · LTVsteel Company · The company has converter 2 × 210, 2 × 255, 2 × 285 (CB)) set a record converter furnace age world record 18,600 furnaces. The main mechanism of the process is that after the tapping, the nitrogen gas is blown into the furnace to blow the slag by tapping gun, and the slag is uniformly sprayed on the surface of the lining to carry out the drossing operation. The specific content of the technology for the United States patent. Japan’s Nippon Steel and Tianjin Jun 1 converter (250t) in November 1975 hit 10110 furnaces, Japan Fukui converter hit 8000 furnaces. Japan generally do not pursue how high a single furnace, but to take “economic furnace ”. Japan’s iron and steel industry on the increase in furnace and integrated charge unit consumption, overhaul brought
