Hot rolled steel ball technology
Hot rolled steel ball technology:Ball diameter range Φ20-Φ150mm. Rolling ball milling is used in a variety of chemical composition billets rolled round bars, its diameter is equal to the nominal diameter of the ball. The main production process of hot rolling steel ball as follows:1, After the round bar examination, by length cut into steel ball billet.2, The steel billet heated to a suitable temperature in a continuous heating furnace before rolling.3, After the red-hot state steel billet feeding into the ball mill, forward rotation in between special spiral grooved rollers, and is continuously rolled into a ball. Each steel skew ball mill can roll 60-360 steel ball per minute.4, The red hot ball rolled into special designed online heating treatment furnace for quenching – tempering heat treatment, so can get high uniform hardness ball.5, After inspection steel balls sent to the finished goods warehouse, after packaging then sent to customers.
