Product Overview

Description



Forged and Casted Steel Ball


Product Description




Rolling Ball Introduction:
Hol-rolled steel ball is a newly emerged technology in recent years. The process principle is that two screwedroll molds rotate in the same direction and drive the steel rod to rotate in the opposite direction and move forward to produce the balls of desired sizes under the force of the mold.
It has the following features:
1.High production efficiency,Great yield, high degree automatization.
2.Stable quality, uniform hardness, good hard enability, micro structure dense, high impact toughness, low breakage rate.
3.Advanced heat treatment process, low labor intensity, no pollution, lower production costs.
