因钢材脱炭而造成质量不合格,是各特殊钢厂普遍存在的重大质量问题之一.大连钢厂在1955年下半年?6钢成品曾一度只达?,脱炭废品遍及每一炉号;大冶钢厂1955年上半年?15钢因脱炭不能交货的共41批,占本身废品总量的74.2%,1956年7月上旬此钢材全部因脱炭而报废;大连和抚顺两厂的几种硅弹簧钢材的脱炭问题长期未能很好地解决,一直采用剥皮的方法给人力、物力带来很大损失,虽然如此,仍然不能完全消除脱炭废品;本溪钢厂的?15钢及102厂的炭素工具钢也因脱炭造成很多废品.钢材脱炭严重,以致常有用户提出退货.我所曾针对这一重大质量问题作了许多研究工作,为便于更好地推广、应用以及在此基础上作进一步的研究提高,特总结于下.
Unfunded quality of steel due to decarbonization, is a common major steel mills all the major quality problems .Dalian steel mills in the second half of 1955? 6 steel products once reached only ?, off-charcoal throughout each heat number ; Daye 1955 first half of steel? 15 due to off-carbon can not be delivered a total of 41 batches, accounting for 74.2% of its total scrap, the early July 1956 all of this steel scrapped and scrapped; Dalian and Fushun two Some of the silicon plant spring off the carbon steel problem has not been well resolved, has been using the skinning method to human, material and great losses, however, still can not completely eliminate the off-charcoal scrap; Benxi Steel? Carbon steels of 15 and 102 also caused a lot of rejects due to decarbonization, so steel was severely decarbonized, so that users often returned goods. I have done a lot of research work on this major quality issue. In order to facilitate better promotion , Application and on this basis for further research and improvement, especially summarized below.
