For the 55SiCr valve spring steel with strict service condition
its deoxidation
desulfurization and inclusion change are studied by laboratory experiments under a low oxygen condition by adding SiCaBa alloy into the molten steel. The results show that SiCaBa alloy has the effect of deep deoxidation and desulfurization
as well as refining the inclusion size. By adding 0.48 kg/t steel of SiCaBa alloy with 49. 8% Si-25. 6% Ca-11. 1% Ba and a proper amount of refining slag with Fe
