为考察楔横轧二次楔轧制在超大断面收缩率情况下的成形规律,在H630轧机上进行了不同工艺条件下的超大断面收缩率轧制实验,得到各工艺参数对轧制质量的影响规律,发现在超大断面收缩率情况下二次楔的工艺参数对内部缺陷和拉断加工界限有决定性影响.结果表明,只要参数得当,二次楔轧制可以获得合格的大断面收缩率轴类件.
In order to investigate the forming regularity of secondary wedge rolling of wedge cross-rolling under the conditions of super-large section shrinkage, the rolling experiment of super-large section shrinkage under different conditions was carried out on H630 rolling mill, and the influence of various process parameters on rolling quality was obtained The results show that the process parameters of secondary wedges have a decisive influence on the internal defects and the breaking boundaries when the superconducting shrinkage is high.The results show that as long as the parameters are right, Pieces.
