ZBH44004—88制绳钢丝用无扭控冷热轧盘条第4·5·3条规定:“盘条不得有淬火组织(马氏体和屈氏体马氏体区域),供方在工艺上有保证时,可不作检验。” 经查阅ZBH44004—88标准档案,没有说明本条规定的原由和出处,只见到制定本标准时参考的标准清单和各国标准检验项目对比表,均无显微组织检验要求。后来我按照档案提供的线索查找各国现行标准,结果如下: ISO/DP—83没有找到,只找到ISO8457.2—1989拉拔用非合金钢盘条,其中无显微组织检验要求,该标准正在组织修订,但没见到DP草案。
ZBH44004-88 wire rope without twist twist hot and cold-rolled wire rod Article 4.5.3 stipulates: “There shall be no quenching wire rod (martensite and martensite martensite region), the supplier in the process When warranted, may not be tested. ”After consulting the ZBH44004-88 standard file, did not explain the reasons and sources of this article, only to see the development of this standard reference list of standards and national standard test items comparison table, no microstructure inspection Claim. Later, according to the clues provided by the archives to find the current national standards, the results are as follows: ISO / DP-83 did not find only to find ISO8457.2-1989 drawing non-alloy steel wire rod, which microstructure inspection requirements, the standard is Organizational revision, but no DP draft.
