在一九七三年七月召开的封闭炉技术经验交流会议上,我们总结了9000KVA旋转密闭硅锰合金电炉自一九六九年二月投产以来的经验和教训,提出了对几个问题的看法,以“9000KVA旋转密闭硅锰合金电炉几个问题的探讨”(以下简称“探讨”)为题,发表在《铁合金》一九七三年第三期上。为了进一步摸索和掌握旋转密闭电炉的生产规律,提高生产水平,改善电炉技术经济指标,在厂党委的正确领导下,通过批林批孔运 At the exchange of experience in closed furnace technology held in July 1973, we summarized the experience and lessons learned since the commissioning of the 9000KVA rotary closed silicon-manganese alloy furnace in February 1969, and put forward several proposals View, to “9000KVA rotary closed silicon-manganese alloy furnace several issues of discussion” (hereinafter referred to as “discussion”) entitled “Ferroalloy” in 1973 third period. In order to further explore and grasp the rotation of closed furnace production law, raise the level of production, improve the technical and economic indicators of the electric furnace, under the correct leadership of the factory party committee, approved by the approved Lin hole
