变态箱型孔轧制大规格圆钢的生产实践

Production Practice of Rolling Large Gauge Round Steel with Abnormal Box Groove

针对新钢特殊钢有限责任公司锻造厂生产Ф120 mm,Ф130 mm圆钢效率低、成本高问题,提出了以轧代锻的方案和变态箱型孔的设计方法,重点介绍了Ф650 mm轧机轧制Ф120～130 mm圆钢精轧孔型工艺参数的选择和确定,并把变态箱型孔应用于轧制实践,实现了以轧代锻,取得良好的效果.

In order to solve the problems of low-effect and high-cost in produing Φ120 nm, Φ130 mm round-bar steel in the forging plant of Xinsteel special steel Co. , Ltd, this paper puts forward a method to select and use the technological parameter of Φ650 mm rolling mill to roll Φ120 mm-Φ130 mm round-bar finishing groove and puts the abnormal box groove into rolling to replace the forging, thus makes a good econmic effect.
