摘要
为了不进行较大设备投资,不增加轧制道次,实现用大规格坯料轧制小规格棒材,在棒材厂的组合传动三机架连轧机列上开发了轧辊切分工艺,该切分工艺包括两个预切分道次,一个切分道次,采用并联扁六角切分孔型,经三个道次将方轧件切分成两条扁六角轧件,该工艺达到了预期目的,同时取得吨材生产成本下降 10%,机时产量增加 50%的效果。
In order to produce the small-size bar in use of the big-size billet without making much investment in e-quipment and adding rolling pass, roll slitting bar rolling technique is developed on continuous rolling mill with three-stand, group-driven by single motor. This slitting technique is introduced as follow: it consists of two pre-slitting passes and one slitting pass, adopting parallel flat-hexagonal pass, a square piece is sliced into two flat-hexagonal pieces by three passes. The desired goal of the technique has been reached, and the results in the production cost of tonnage bar decreased by 10% and in the yield of man-hour increased to 50% have been attained.
