Abstract

Abstract

The quality level of 34Mn2V steel produced by continuous casting was presented.Considering the properties and applications of 34Mn2V steel,the technologies,such as ladle Ar stirring,LF/RH refining,mold electromagnetic agitating,overheating degree control during continuous casting and light reduction,were used,as a result,high cleanliness and good surface quality of 34Mn2V steel were obtained,and [H]≤1.8×10^-6;T[O]≤12.0×10^-6,A type inclusions ≤2.0 grade,B and C type inclusions ≤1.0 grade and D type inclusions ≤1.5 grade.The properties of high pressure seamless gas cylinders after punched were stable,the strength and toughness were relatively high and the requirements of service safety can be met.
