前言目前国内每年轧辊消耗量很大,费用昂贵、供不应求。特别是由于它的质量跟不上形势的发展,磨损量和断辊次数也在增多。我们走访了全国一些钢厂的轧辊使用情况,感到必须扭转这一落后于国外的情况,赶上和超过国际先进水平。我国与国外水平对比见表1:

Preface At present, the annual domestic roll consumption is large, expensive, in short supply. Especially because of its quality can not keep up with the development of the situation, the amount of wear and the number of broken rollers is also increasing. We visited the roll usage of some steel mills across the country and felt it necessary to reverse this backwardness and catch up with and surpass the international advanced level. The comparison between China and foreign countries is shown in Table 1:
