【摘要】 介绍采用150 mm×150 mm连铸坯试制ML08A l冷镦线材的过程,从化学成分、低倍组织、高倍组织、力学性能等方面分析线材性能。随着硅含量的增加,钢的抗拉强度和硬度增大,延伸性能下降,当成品的硅含量不大于0.10%时,冷镦合格率可大大提高。更多还原

【Abstract】 To introduce trial production course of ML08Al wire rod for cold heading from 150 mm×150 mm continuous casting billet.Properties of wire rod are analyzed from such aspects as chemical component,microstructure of low times,microstructure of high times,mechanical property.Tensile strength and hardness of steel are improved,but elongation reduces with increasing mass fraction of Si.When mass fraction is controlled lower than 0.10%,pass rate of cold heading is increased greatly.更多还原
