Rebuilding of a bloom caster from two strands to three

为满足中国高速铁路发展需要,马钢将一台双流大截面圆坯连铸机改造为三流,在消化原引进关键技术和设备的同时,从工艺、设备、控制等方面进行一系列优化和国产化研究。改造后的连铸机投入生产一年多的实践证明达到了预期目标。

In order to meet the development of the high speed train in China,Masteel have rebuilt a bloom caster from two strands to three,and made a series of the optimization and the research on the technique,equipment and control through digesting the key imported techniques and qpuipments.Affer being on stream for one more year,the changed caster has been proved in practise to achieve the expecting aims.
