摘要
莱钢特钢厂通过采取精料、电炉冶炼全程泡沫渣、LF精炼和VD真空脱气等措施,生产出的SAE8620H钢具有淬透性带窄、纯净度高、晶粒细小均匀、表面质量优良等优点,完全能够满足高性能汽车齿轮的需要。
Through the concentrated feed, electric-furnace smelting with the entire journey foamed slag, LF fining and VD vacuum degasification etc measures, the Special Steel Plant of Laiwu Steel produced American standard SAE8620H steel with narrow hardenability band, high purity, thin and even crystal grain and fine surface quality and so on. This steel grade can meet completely the needs of the high performance automobile gear.
