随着市场形势的变化,北营轧钢厂二棒材逐步转向生产附加值较高的小规格螺纹钢。2010年成功开发了Φ12mm带肋钢筋四切分轧制工艺。2012年9月份着手开发极限规格Φ10mm带肋钢筋四线切分工艺,并于2013年1月首次轧制取得成功。随着四线切分工艺不断改进与完善,大大提高了北营轧钢厂小规格螺纹钢的市场占有率。
With the change of market situation, the second bar of Beiying Rolling Mill gradually turned to produce small-sized rebar with higher added value. In 2010 successfully developed Φ12mm ribbed steel four splitting rolling process. In September 2012, we started to develop the four-wire cutting method of the ultimate size Φ10mm ribbed steel bar and achieved the first rolling in January 2013. With the continuous improvement and improvement of the four-line cutting process, the market share of the small-size rebar in Beiying Rolling Mill has been greatly raised.
