New-Generation Intelligent Steel Ball Production Line

A brand-new intelligent steel ball hot rolling heating machine has been officially released for industrial mass production, bringing comprehensive upgrades to the manufacturing of wear-resistant steel balls, bearing steel balls and grinding media. Widely applied in mining, cement, thermal power and chemical industries, traditional steel ball production equipment has long been plagued by unstable roundness, inconsistent hardness, low automation and high material waste. The newly launched integrated production line integrates intelligent heating, precise rolling, automatic heat treatment and intelligent screening, effectively solving industry bottlenecks and boosting the overall quality and production efficiency of finished steel balls.

The core advantage of the new production line lies in its optimized thermoforming and heat treatment system. Equipped with a high-precision medium-frequency induction heating module, the equipment achieves uniform heating at 900–1100℃ for steel bar blanks, ensuring consistent internal metallographic structure before rolling. The upgraded skew rolling mill adopts special spiral pass rollers, enabling continuous rotary forming of steel blanks. The whole forming process is stable and efficient, with a production speed up to 120 steel balls per minute, completely avoiding defects such as ellipticity, surface burrs and hollow cores common in traditional forging and rolling processes.

This new generation of production line achieves full-process intelligent control. The built-in PLC intelligent system realizes one-click parameter switching for different specifications of steel balls, with automatic tracking and adjustment of heating temperature, rolling speed and quenching flow. The supporting intelligent screening module automatically classifies products by diameter, roundness and surface quality, eliminating manual detection errors. The one-time product qualification rate is increased to over 99%, while material utilization rate is improved by 25%.
