Embodiment 1
[0021] A method for producing ball mill grinding rods with a size of φ30mm×50mm is that the chemical composition of the grinding rods is selected as (wt, %): 1.8C, 0.9Si, 0.8Mn, 0.2V, 0.09Ti, 2.5Cr, 0.4Cu, 0.15 Ni, P, Sfigure 1 ). The molten steel is smelted in an intermediate frequency induction furnace. The tapping temperature is 1450~1500℃, the pouring temperature is 1400~1450℃, and the box is boxed 10-15 minutes after pouring. The air quenching temperature is 800~900℃. After cooling, it is polished and cleaned. Library.
