武钢从西德麦索(MESSO)公司引进的一套RH真空设备,自1979年10月投产至1986年底,迄今已精炼各类试验钢和硅钢共计3789炉约25.4万吨。其中1986年生产1583炉11.1万吨,超过设计能力54％。七年来,武钢在真空精炼的应用上做了不少工作,本文仅从精炼工艺和设备改进等方面作扼要叙述,以期对今后的生产及新RH真空设备的引进和应用有所帮助。一、RH真空设备概况武钢RH真空精炼炉设置在转炉与连铸
WISCO introduced a set of RH vacuum equipment from MESSO Company. Since its commissioning in October 1979 to the end of 1986, it has refined a total of 3789 furnaces and 254,000 tons of all kinds of test steel and silicon steel to date. Among them, 1583 furnaces produced 111,000 tons in 1986, which exceeded the design capacity by 54%. In the past seven years, WISCO has done a lot of work on the application of vacuum refining. This article only briefly describes the refining process and equipment improvement so as to help the future production and the introduction and application of the new RH vacuum equipment. First, the RH vacuum equipment Overview WISCO RH vacuum refining furnace set in the converter and continuous casting
