摘要
针对冷镦钢盘条冷锻开裂问题,对盘条质量进行了全面检测分析。结果表明,冷镦钢盘条表面质量问题是导致冷锻开裂的根本原因。通过优化减定径机轧制规程,改进NTM,RSM辊环修磨工艺,加强对导卫装置、导轮、起套辊进行检查和更换,解决了盘条冷锻开裂问题。
In light of the cracking of cold upsetting steel in cold forging, testing and analysis were carried Out of the quality of the cold heading steel wire rod. It is found that the surface quality of the wire rod has contributed to the cracking. By optimizing reducing sizing mills instruction, improving NTM and RSM roll collar coping technology, giving attention to the check-up and replacement of guide fittings, guide wheel and loop rising roll, the cracking of the wire rod is resolved.
