1. A single length of 3-4M for the length of the hot-rolled bar for the material stacking → bar heating → steel ball rolling → heat treatment quenching and tempering → quality control → storage → test → sorting → packaging → finished → Ship.
2. Hot-rolled steel ball not only high hardness, good hardenability, hardness distribution is extremely uniform hardness gradient, and the microstructure is particularly dense. Steel ball hardness of up to 58-67HRC, internal and external hardness difference is small; impact toughness up to 15-35J / cm2, broken rate of 0.1%.
3. Rolled steel ball High density, roundness is good, accurate diameter. The finished steel ball usually has two kinds of packaging, iron drum: usually packed 850 or 920KGS / drum, tons of bags: Each bag can hold a ton
