For steel bars, low-carbon alloy steel bars, wind power bolts, anchor bolts, screw rods and hydraulic cylinder rods, choosing a quenching and tempering line is not only about the power of the induction heating system. The bar diameter, length, steel grade, required output and final hardness target should all be considered.

Yuantuo steel bar induction quenching and tempering lines can be configured for Ø20-120 mm bars, with hourly output designed according to the workpiece size and production target. A complete line usually includes loading, rotary feeding, induction heating for quenching, spray quenching, induction tempering, cooling and collecting systems.

During continuous production, the roller axis and the workpiece axis are arranged at a certain angle. The bar rotates while moving forward, which helps improve heating uniformity. The rollers between furnace sections are made of 304 non-magnetic stainless steel with water cooling, helping reduce induction heating of the rollers and improve stable operation.

Temperature control is also a key part of the process. Infrared temperature measurement and PLC closed-loop control can monitor quenching and tempering temperatures in real time. The industrial control system can record workpiece parameters, production data, alarms and historical process information for easier quality tracking.

Before requesting a quotation, buyers are advised to provide bar diameter, length, material grade, required output, hardness target and workshop power conditions. Yuantuo can design a suitable induction heating, quenching, tempering and automatic conveying solution according to the actual production requirements.
