Long Bar Induction Quenching and Tempering Machine | Forever Serbia Project Case

Jul. 31, 2026

Forever Electromechanical achieves another key milestone in the Central and Eastern European market. The customized long bar induction quenching and tempering machine has completed on-site installation, linkage debugging and hot test operation at a metal processing enterprise in Serbia, and has been officially put into continuous mass production. This real overseas project marks the further recognition of Forever’s IGBT induction heat treatment technology among European long steel material manufacturers.

The Serbian client specializes in the production of alloy long bars, mechanical shafts and structural steel components for construction machinery and automotive supply chains. Before cooperation, the factory adopted traditional chamber furnaces for heat treatment. They were plagued by obvious pain points: slow heating speed, serious surface oxidation and decarburization, large hardness deviation along workpieces, high power consumption and low automation. Discontinuous production restricted output expansion, and unstable mechanical properties of finished bars affected the company’s competitiveness in the European market. After comparing multiple equipment suppliers from Europe and Asia, the client finally selected Forever Electromechanical to deliver a full-set continuous induction quenching and tempering production line.

According to the client’s production requirements, Forever’s engineering team optimized the whole line targeting local power grid conditions and processing specifications. The steel bar induction hardening and tempering furnace adopts mature digital IGBT medium-frequency power supply, matched with rotary roller conveying structure and segmented induction coils. Equipped with infrared closed-loop temperature measurement and PLC centralized control system, the equipment realizes automatic feeding, penetrating heating, precise spray quenching, constant-temperature tempering and automatic discharging in one continuous workflow. It effectively controls bar bending deformation, keeps hardness fluctuation within the standard range, and greatly reduces oxide scale loss.

Compared with the original heating mode, the induction heating machine cuts comprehensive energy consumption by over 30%. The whole line supports 24-hour stable continuous operation, reduces manual intervention, and lowers long-term operation and maintenance costs. During the commissioning phase, Forever’s overseas service engineers provided on-site technical guidance, operator training and process parameter optimization. All metallographic inspection and mechanical property tests of treated long bars fully meet EU industrial standards, winning high recognition from the Serbian customer.

As a professional manufacturer of induction heating equipment, Forever Electromechanical keeps launching customized heat treatment solutions for global metal processing factories. This Serbia long bar project expands the brand layout in the Balkan region. Moving forward, Forever will continue to promote energy-saving, intelligent induction quenching and tempering equipment, deliver reliable turnkey production lines for more European manufacturers, and provide full-life-cycle technical support including equipment upgrading, spare parts supply and remote after-sales service.
