摘要
中碳冷镦钢是中、高强度紧固件的主要原材料,连铸过程中铸坯表面增碳,将会造成线材成分偏析、组织异常,镦打过程中严重开裂。
Intermediate carbon cold heading steel is the main material of medium and high strength fasteners, If billets surface carbonization made in the process of continuous casting, Wire shall be caused composition segregation, structure abnormity and serious crack in the process of cold heading.
