    Qualified hot-rolled round steel bars → Heat and Straightness → Quenching → Tempering → Inspection → Packing → Delivery 

 Shandong Huamin Steel Ball Joint-Stock Co., Ltd specializes in researching and producing forged grinding steel balls and grinding steel rods in China. Our expertises designed and installed the first automatic production lines for heat treatment grinding rods in China in 2008 and obtained the related patents. 

The grinding steel rods with heat treatment has the features of high hardness,good wear resistance,no breakage.As a result, the heated grinding steel rods as grinding media can get a lower wear rate and a better longlife in the Rod mills.
