Production of Ultra-low Ozygen Automobile Gear Steel by Converter-Bloom Continuous Casting Process

摘要：

In view of process conditions of Vanadium Recovery and Steelmaking Plant,Panzhihua New steel and Vanadium Co. Ltd. and on the basis of making choice of a reasonable deoxidization process,some measures have been taken to the development of automobile gear steel (20CrMoH) such as the pre-refining technology during converter tapping,white slag refining in LF,RH Vacuum treatment,and even protective casting technology. Also different and suitable models of argon blowing from bottom of ladle were adopted in the platform after converter,LF refining and calcium treatment. Test results show that the high cleanness 20CrMoH gear steel slab with TO ≤15 ×10 -6 (the average TO is 11. 8 x 10-6) could be obtained through all these measures.
