Forever Electromechanical Rolls Out New-Generation Steel Billet Induction Preheating Machine to Solve Core Industry Pain Points

Against the backdrop of global carbon neutrality goals and metallurgical manufacturing’s push for low-cost, high-precision production, steel billet preheating has become a bottleneck restricting rolling and forging enterprises’ profit margins. Outdated heating equipment leads to excessive power consumption, unstable billet temperature uniformity, heavy metal oxidation loss and frequent production downtime. Focused on these long-standing industrial pain points, Forever Electromechanical has launched a fully optimized new-generation steel billet heating and reheating furnace , delivering systematic energy-saving, intelligent and low-maintenance solutions for steel processing clients worldwide.

The metallurgical heating sector currently faces four prominent universal pain points. First, legacy SCR power supply equipment features low energy conversion efficiency, fixed-frequency operation and severe reactive power loss. Most mid-small rolling mills record power consumption above 85 kWh per ton of billet, with 30% of electricity wasted in idle heat loss, pushing up production costs amid rising energy prices. Second, poor temperature consistency plagues traditional heating lines. Without closed-loop intelligent adjustment, the core-surface temperature difference of steel billets exceeds 40°C, triggering rolling cracks, uneven finished product hardness and a 5%-8% increase in defective rates. Third, severe oxidation burning loss cuts raw material yields. Long high-temperature exposure generates thick iron scale, which not only wastes steel raw materials but also abrades downstream rolling rollers, raising maintenance costs and halting production for frequent scale cleaning. Fourth, low automation and unreliable continuous operation create labor and downtime losses. Conventional equipment lacks automatic parameter matching and early fault warning; coil burnout and power shutdown failures force 2–3 hours of maintenance per breakdown, disrupting 24-hour batch production.

Targeting these pain points, Forever Electromechanical integrates 18 years of induction heating R&D experience to build a comprehensive technical upgrade solution centered on IGBT digital variable-frequency power supply and full closed-loop intelligent control. The core power unit abandons outdated silicon controlled rectifier modules, adopting high-efficiency SiC IGBT inverter technology that dynamically matches output power based on billet size, material and initial temperature. Field test data verifies a 28% reduction in unit power consumption, cutting electricity expenditure by hundreds of thousands of USdollars for large-scale rolling factories annually.

For temperature uniformity, the machine is fitted with multi-point infrared pyrometer closed-loop regulation and segmented coil magnetic field optimization. It restricts internal-external temperature deviation within ±12°C, eliminating forging and rolling defects caused by uneven heating. The optimized rapid heating structure shortens high-temperature exposure time, lowering oxidation burning loss below 0.25% and boosting metal yield significantly. In terms of intelligent operation, the dual-core PLC+DSP control system stores over 100 sets of heating process parameters for one-click switching across carbon steel, alloy steel and stainless steel billets. Equipped with IoT remote monitoring, real-time energy consumption statistics and predictive fault diagnosis, the equipment cuts manual operation dependence by 60% and reduces unplanned downtime by over 70%.

A senior R&D engineer from Forever Electromechanical stated that the company will continue to iterate induction heating core technologies, expand customized solutions for special alloy billets, and assist global metallurgical enterprises in realizing low-carbon, high-efficiency and intelligent production amid stricter environmental and energy consumption standards.
