北京冶金设备研究院开发高效连铸技术取得成效,近两年先后为宣钢炼钢厂1号、2号、4号连铸机进行改造设计,4号机已于近日投产,拉速稳定在1.8～2.5m/min,单流年产量可超15万t。上海浦钢公司转炉炼钢厂2号连铸机实施的改造工程于2000年4月初已竣工投产,拉速稳定在2.5m/min左右。该 Beijing Institute of Metallurgical Equipment Development of high efficiency continuous casting technology has achieved success, the past two years has Xuanhua Steel Mill No. 1, No. 2, No. 4 continuous casting machine to transform the design, Unit 4 has been put into operation recently, pull speed stable at 1.8 ~ 2.5m / min, single-stream annual output can exceed 150,000 t. Shanghai Pudong Iron and Steel Company converter plant on the 2nd continuous casting machine to implement the transformation project in early April 2000 has been completed and put into operation, pulling speed stabilized at 2.5m / min or so.
