高铝38 CrMoAl钢增铝合金化工艺研究

Research on Process of Adding Aluminum in High Aluminum 38CrMoAl steel

38CrMoAl钢中[Al]含量极高（ω[Al]为0.7%~1.1%）,采用连铸生产易导致水口的堵塞,如何进行加铝工艺保证38CrMoAl的高铝含量且不影响该钢种的其他元素的成分以及改良精炼渣渣系充分吸收夹杂物、连铸采取相应保护措施、选择合适的保护渣是38CrMoAl进行连续多炉连铸生产的关键。

Because of very high content of [Al]（ω[Al] is within 0.7%~1.1%）in 38 CrMoAl steel, the nozzle iseasy to be clogged during the process of continuous casting production of this steel, so adding aluminum process forensuring high aluminum content in 38CrMoAl steel and not influencing other elements in 38 CrMoAl steel, andimprovement of refining slag system for absorbing inclusion fully, taking the corresponding protective measures forcontinuous casting, selecting the appropriate protecting slag, are the keys for continuous casting production of 38CrMoAl steel with successive heats.
