49mm×51mm异形方钢的热轧成型技术

49mm×51mm Special-shaped Square Steel Hot-rolled Molding Technology

在湖北新冶钢有限公司二轧钢厂500/半连轧机组上,采用无孔型热轧工艺生产宽厚比非常接近的异形方钢,经多次试验和改进,生产成功,其关键成型技术是鼓形宽展的控制。

In the 500/semi-continuous rolling mill group of No.2 Rolling Factory,Hubei Xinyegang Steel Co.,Ltd.,uses non-pass hot rolling process production special-shaped square steel of compared to the very close in width and side,after experiments many times and improves,produces successfully,its key molding technology is the control which the drum shape spreads.
