H08Mn2SiA盘条拉拔性能研究

研究化学成分对H0 8Mn2SiA盘条拉拔性能的影响。分析认为 ,H0 8Mn2SiA中w(C) =0 .0 5 %,w(Si) =0 .81%,w(Mn) =1.80 %时焊丝拉拔性能最好。H0 8Mn2Si属双相钢 ,在制订拉拔工艺时前 3道面缩率应较高 ,如 6.5→ 5 .3→ 4 .3→ 3 .8mm时 ,可达 3 3 .5 %、3 4 .2 %、2 1.9%较合适。

Drawing Property Research of H08Mn2SiA Wire Rod

To research the effect of chemical composition on drawing property of H08Mn2SiA.It is thought by analyses that the drawing property of welding wire is the best when mass fraction w (C), w (Si), w (Mn)is equal to 0.05%,0.81%,1.80% respectively in H08Mn2SiA wire Rod.H08Mn2SiA is belong to dual phase steel,so higher draught is suitable at former three passes in drawing,for example,when wire rode is drawn from 6.5→5.3→4.3 to 3.8?mm,the draught should be up to 33.5%,34.2%,21.9%respectively.
