我厂铸工车间1.5吨电弧炼钢炉是全厂唯一的重点炼钢设备。电炉炉盖一直是采用高铝砖人工筑砌,质量低,寿命短,直接影响电炉作业率。筑砌炉盖时,工人劳动强度大,费时很多。为了提高电炉作业率,生产更多更好的铸钢备品备件,支援矿山建设,在厂党委领导下,在群众性技术革新运动中,在吸收外来经验的基础上,我们试制成功了电炉全水冷炉盖。自 I 1.5 tons cast iron plant arc furnace steelmaking plant is the only focus of steel equipment. Furnace lid has been the use of high-alumina brick artificial building, low quality, short life, a direct impact on the operating rate of the furnace. When building a furnace cover, workers are labor-intensive and take a lot of time. In order to improve the operating rate of the electric furnace, to produce more and better spare parts for the steel castings and to support the construction of the mines, under the leadership of the factory party committees and on the mass technological innovation movement, on the basis of absorbing foreign experience, Hearth. from
