目前国内交流串级调速技术在单机上使用已有一定的经验,一些单位也进行了在连轧机上的试验研究。我们组成了三结合试验小组,在北京钢铁学院200毫米四机架交流串级调速热连轧机上进行试验,取得初步成果,为700毫米交流串级调速半连续式热连轧机的设计制造取得一些有价值的数据。 At present, the domestic exchange cascade speed control technology has been used on a single machine has some experience, some units also conducted a pilot mill on the research. We formed a triple combination of experimental group, in the Beijing Institute of Iron and Steel 200 mm four-rack AC cascade speed tandem hot mill test and achieved initial results for the 700 mm AC Cascade semi-continuous hot-rolling mill design and manufacture Get some valuable data.
