素形材.1991,1(46) 为开发宇宙而研制的等离子射流技术已应用到了冲天炉这一古老设备上,实现了具有200年历史的冲天炉与宇宙时代最新技术的有机结合。这就是1989年夏在GM的Central Foundry诞生的以六个电动等离子射流管为加热源的45t/h冲天炉。这座等离子熔化炉的研制花了近六年时间投资数亿日元,实现了提高铁水质量、降低生产成本的愿望。该炉是由Westingkouse、
Profiled Materials .1991, 1 (46) Plasma jet technology developed for the development of the universe has been applied to the ancient cupola device, achieving a 200-year-old cupola and the latest technology in the universe. This is the 45t / h Cupola, which was started in June 1989 at the Central Foundry in GM and powered by six electric plasma jet tubes. The plasma melting furnace development spent nearly six years to invest hundreds of millions of yen, to achieve the desire to improve the quality of hot metal, reduce production costs. The stove is made by Westingkouse,
