上钢三厂转炉车间原有连铸机四台,配合三座25T氧气顶吹转炉。为了进一步挖掘浇注系统的潜力,扩大连铸坯产量和连铸比,解决第四台连铸机负荷过重,设备缺乏维护问题,因而决定增建第五台连铸机。 第五台连铸机从1976年2月起开始设计、制造、安装和试浇,于1978年8月下旬投入三班作业生产,至1981年8月底,三年来共浇铸钢19085炉53.25万吨。1979年转炉车间连铸坯产量增加了12万吨,连铸比提高了2.98％,1980年连铸坯产量增加了20万吨,
On the steel plant three original converter four continuous casting machine, with three 25T oxygen top blown converter. In order to further tap the potential of the casting system, to expand the continuous casting production and continuous casting ratio, to solve the fourth caster overloaded, the lack of maintenance of equipment, which decided to build a fifth caster. Fifth continuous casting machine from February 1976 onwards began to design, manufacture, installation and test pouring, in late August 1978 put into three shift operations, to the end of August 1981, a total of 3,035,000 tons of steel furnace 19085 were cast steel . In 1979, the output of continuous casting slab in the converter workshop increased by 120,000 tons and the continuous casting ratio increased by 2.98%. In 1980, the output of continuous casting slabs increased by 200,000 tons,
