摘要
本钢采用EBT→LF→VD→连铸235mm×265mm方坯→缓冷→加热→棒材连轧机组→缓冷→精整→检验→包装缴库→发货的工艺流程,成功研制生产了高档轿车齿轮用钢20Cr Ni2Mo SH。产品化学成分均匀,有害元素及气体含量低,末端淬透性稳定,钢材组织均匀,纯净度高,致密度好,满足了高档轿车齿轮用钢的使用要求。
The high grade gear steel 20 Cr Ni2Mo SH for automobile of BX Steel is successfully produced by the follow sheet ： EBT → LF →VD→ caster 235 mm×265 mm square billet→ slow cooling → reheating →continuously roll →slow cooling →finishing →inspection → packaging and pay into treasury → shipment. The product has series of the qualities, including homogeneity of chemical composition, low content of harmful elements and gas, stable end- quench hardenability, compact and uniform organization, high purity, meeting the operating requirements of the high grade gear for automobile.
