我厂是建于五十年代的老厂,二十多年来通过逐步更新改造,生产能力于1985年达到235万吨(设计能力),而炉后铸锭设备由于没有进行较大的改造,生产能力尚停留在原200万吨的水平上。根据我厂生产实际情况,除去十年内乱时期,炼钢生产可大致分为三个阶段。第一阶段是1959年到1966年,由于设备新,生产工艺条件逐渐完善,生产以较高速度发展;第二阶段是1978年到1984年,设备渐趋陈旧,炉前炉后生产能力不配套,问题随产量提高而暴露,致使生产发展速度缓慢,甚至停滞不前;第三阶段是1985年至
Our factory was built in the fifties old factory, over 20 years through the gradual renovation and transformation, production capacity in 1985 reached 2.35 million tons (design capacity), and after-furnace ingot equipment because there is no major transformation, Production capacity is still stuck in the original level of 2 million tons. According to the actual situation of our factory production, except during the 10 years of civil strife, the steelmaking production can be roughly divided into three stages. The first stage is from 1959 to 1966, due to new equipment, production process conditions gradually improved, the production at a high speed development; the second stage is from 1978 to 1984, the equipment is getting old, the stove before furnace capacity is not complete , The problem with the increase of production exposure, resulting in the slow development of production, or even stagnant; the third stage is from 1985 to
