BL1盘条拉拔性能试验研究

Test Research on Drawing Property of BL1 Wire Rod

对BL1盘条进行拉拔性能试验研究 ,通过结果对比 ,摸索出BL1盘条的最佳化学成分、力学性能 ,优化出钢丝最佳生产工艺参数。粗、中拉平均部分压缩率为 2 3% ,拉拔速度为 2 .4m/s ,细拉平均部分压缩率为 14 % ,拉拔速度为 3.5m/s,保持良好的润滑和冷却 ,可将 6 .5mm高线盘条拉拔到 0 .70mm以下 ,总压缩率超过 99%。

To research the drawing property of BL1 wire rod by experiments. The optimum process parameters to produce steel wire are optimized by means of comparing the results and fishing out the chemical composition and mechanical property of BL1 wire rod. When the average section draughts of coarse and medium drawing are 23% and drawing speed is at 2.4 m/s,the average section draught of fine drawing is 14% and drawing speed is at 3.5 m/s,and keeps good lubricating and cooling,the high speed wire rod with 6.5 mm diameter can be drawn to bellow 0.70 mm diameter whose total draught exceeds 99 percent.
