我国中板轧制过程中板坯产生弯曲现象是普遍存在的问题 ,北京科技大学与马鞍山中板厂联合攻关 ,历经一年半时间 ,使该难题获得解决。改造措施实施后 ,经两年多的现场考核 ,使机架辊的寿命提高近 6倍 ,板坯的结疤减少 90 %以上。同时提高了成材率 ,减少了非计划检修时间 ,获得了 The bending phenomenon of slab in the process of plate rolling in our country is a common problem. After Beijing University of Science and Technology and Maanshan Medium Plate Factory jointly tackled the problem, after a year and a half, the problem has been solved. After the implementation of the improvement measures, after more than two years of on-site examination, the life of the rack roller increased by nearly 6 times, and the scarring of the slab decreased by over 90%. At the same time improve the finished product rate, reducing the unplanned maintenance time obtained
