简要说明了宝钢一炼钢新建 2RH真空脱气设施的必要性 ,重点介绍了 2RH采用的顶枪技术、真空系统、纯水闭路循环机械冷却水系统及EIC三电一体化控制系统。新建的 2RH真空脱气设施不仅脱碳、脱氢速度快 ,而且具有化学加热钢水、喷粉脱硫、喂丝吹氩等功能 ,真空槽可保持较高的温度 ,大大减少了槽内结冷钢的可能性 The necessity of newly built 2RH vacuum degassing facilities in a steelmaking plant of Baosteel is briefly described. The top gun technology used in 2RH, the vacuum system, the pure water closed - circuit mechanical cooling water system and the EIC three - in - one integrated control system are introduced. The new 2RH vacuum degassing facilities not only decarburization, dehydrogenation speed, but also with chemical heating molten steel, dusting desulfurization, feeding wire blowing argon and other functions, the vacuum tank can maintain a high temperature, greatly reducing the tank cold-rolled steel The possibility of
