主　　题：low chromium semi-steel grinding ball cross rolling mechanical property 

摘      要：The preparing method,rolling technology and mechanical properties of low chromium semi-steel grinding ball by cross rolling were *** results show that when the low chromium semi-steel bar is forged from55mm to50mm,cross-rolled into grinding ball at 1 000-1 050℃,air cooled and tempered at 550℃for 2h,the best mechanical properties,especially the abrasive resistance under the action of hard abrasive,can be obtained.
