近年来国内有些钢铁厂也在积极试验研究硬质合金组合轧辊,目前仍处于试验改进中。总之,我们认为每种工艺都有它一定的适应范围,当前我国轧辊制造试验研究的任务,在于根据不同要求,发挥各自优势,选用经济效果最好的工艺,因此除了致力于离心铸造轧辊的试验研究以外,对已有相当基础的冲洗法复合浇铸轧辊工艺,也应重视与发展,并注意采用花钱不多却能铸造出含有较高合金辊面材料轧辊的滑动水口工艺,探索把复合浇铸轧辊从复合铸铁发展到复合铸钢,以便在更广泛的范围内,发挥这一范围的优点。此外要注意应用硬质合金辊套,研究辊与套之间的先进结合形式。我们应力求在现有条件下,努力提高技
In recent years, some domestic steel mills are also actively testing the combination of carbide rolls, is still in trial and improvement. In short, we believe that each process has its own range of adaptation, the current task of our country roll manufacturing pilot study is to play their respective advantages according to different requirements, the selection of the best economic process, so in addition to commitment to the centrifugal casting roll test In addition to the research, there should be considerable attention and development to the process of compound casting roll with fairly basic flushing method. At the same time, attention should be paid to the process of sliding the nozzle with the roll with the higher alloy roll surface material, Rolls have evolved from composite cast irons to composite cast steels to take advantage of this range in a broader context. In addition, attention should be paid to the application of hard alloy roll covers to study the advanced combination of roll and cover. We should strive to improve our skills under the existing conditions
