New-Generation Hot Rolling Steel Ball Making Machine Line

With the rapid upgrading of mining, metallurgy and building materials industries, the market demand for high-precision, high-wear-resistant steel balls continues to grow, while traditional casting and forging production processes are plagued by low efficiency, unstable product quality and high energy consumption. To solve industry pain points, the newly upgraded full-automatic hot rolling steel ball forging induction heating machine has been officially put into commercial operation, bringing revolutionary changes to the precision manufacturing of grinding steel balls and promoting the intelligent and green transformation of the metal ball processing industry.

Different from conventional steel ball production equipment, this new steel ball forging induction heating machine adopts advanced spiral skew rolling forming technology and integrates a full-process intelligent production system covering automatic feeding, medium-frequency induction heating, precise hot rolling, online shaping, constant-temperature cooling and intelligent sorting. It realizes one-stop unmanned production from raw round steel bars to finished steel balls, completely breaking the limitations of intermittent production of traditional processes. The equipment supports the production of steel balls with specifications ranging from 20mm to 150mm, covering mainstream models required for mining mills, cement plants and thermal power plants, with strong production adaptability and market compatibility.

Technological innovation constitutes the core competitiveness of the new automatic steel ball hot rolling production line. Equipped with a full PLC automatic control system and high-precision infrared temperature measurement device, the line achieves accurate real-time monitoring and adjustment of rolling temperature, stabilizing the core heating temperature at 950℃ to 1100℃. This precise temperature control ensures dense internal structure, uniform texture and excellent mechanical properties of hot-rolled steel balls, effectively improving product wear resistance and impact toughness. Compared with cast steel balls, the dimensional accuracy of products is increased by more than 15%, and the yield strength and service life are significantly improved, greatly reducing the replacement frequency of grinding balls for industrial users.

In terms of production efficiency and energy conservation, the upgraded equipment shows outstanding advantages. The optimized IGBT induction heating technology reduces comprehensive power consumption by more than 20% compared with traditional equipment, achieving low-emission and low-consumption green production. The modular structural design simplifies equipment installation, operation and daily maintenance, and realizes one-person auxiliary operation for the entire line, greatly reducing labor costs. The continuous rolling production mode boosts the hourly output to 8-24 tons, with a finished product qualification rate stabilized above 99%, effectively solving the problems of low output and high defective rate of traditional production lines.
