目前全球共有约600台氧气转炉正在运行,年产量约45000万t,占总产量的60％左右。自从1952年奥钢联公司在奥地利林茨投产了第一台转炉以来,经过50年的持续改进,现代化高效转炉的设计,能够应对高温、机械冲击和热应力等恶劣条件的挑战,在延长炉壳寿命、增大装料量、降低维护要求等方面取得了很大进展。悬挂系统是延长炉壳寿命的重要因素。为经济生产优质钢种,还开发了副枪、挡渣器、底吹和综合自动化系统。
There are currently about 600 oxygen furnaces in operation around the world, with an annual output of about 450 million tons, accounting for about 60% of the total output. Since the establishment of the first converter in Austria in Linz in 1952, after 50 years of continuous improvement, the design of a modern and efficient converter can meet the challenge of harsh conditions such as high temperature, mechanical shock and thermal stress, Shell life, increasing the amount of loading, reduce maintenance requirements and made great progress. Suspension system is an important factor to extend the life of the shell. For economic production of high quality steel, also developed a sub-gun, slag blocking device, the end of blowing and integrated automation system.
