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。
Medium carbon cold heading steel is the main raw material of medium and high strength fasteners. The surface of slab in the process of continuous casting increases carbon content, which will cause segregation of wire composition and abnormal organization, and cause severe cracking during upsetting.
