我厂原设计有2座3.66×6.1米卧式转炉,1座生产,1座检修备用。后来,将转炉炉身加长1米,一次作业产出的粗铜量由过去的40吨增加到50吨。随着生产的不断发展,1969年我们又增建1台转炉;2座生产,1座检修备用。无产阶级文化大革命,特别是批林批孔运动以来,转炉工人认真贯彻抓革命,促生产的方针,大搞技术革新,不断改进操作方法,日产水平超过了设计能 My factory originally designed two 3.66 × 6.1 m horizontal converter, a production, a maintenance spare. Later, the converter body was lengthened by 1 meter and the amount of blister produced by one operation was increased from 40 tons to 50 tons. With the continuous development of production, we built another converter in 1969; 2 production and 1 maintenance standby. Since the great proletarian cultural revolution, especially since the campaign approved the pro-Lin movement, the converter workers have conscientiously implemented the guidelines of revolution and production promotion, vigorously promoted technological innovation and constantly improved their methods of operation. The daily production level surpassed the design energy
