medium and thick steel plate heat treatment

Sep. 14, 2026

In the field of medium and thick steel plate heat treatment, induction hardening machines have become core processing equipment due to their high heating efficiency, small deformation and controllable performance. With years of in-depth research and on-site commissioning experience in induction heat treatment equipment, Forever Electromechanical has formed mature commissioning technologies targeting the characteristics of medium and thick steel plates, including special material properties, wide thickness range and high uniformity requirements for hardened layers. This article summarizes the systematic on-site commissioning key points based on practical operation experience, solving common industrial problems such as unstable equipment operation, uneven quenching and unqualified hardness.

1. Pre-operation Inspection to Lay a Solid Foundation for Commissioning

Comprehensive pre-inspection before on-site commissioning is essential to eliminate potential faults and ensure smooth operation. Technicians need to fully check the overall mechanical structure, electrical system and cooling system of the equipment to eliminate hidden dangers such as loose circuits and pipeline leakage. Core components including induction power supply, transformer and inductor are inspected one by one to confirm no mechanical damage and normal operation of electrical parts. Meanwhile, the operating status of cooling pumps and quenching pumps is verified, and pipeline pressure and flow are adjusted to maintain stable water circulation and prevent equipment overloading. After completing hardware inspection, start the self-inspection program. After system parameters return to normal, preheat the equipment for 5 to 10 minutes to stabilize the circuit and temperature control system, preparing for formal parameter debugging.

2. Precise Inductor Calibration to Ensure Uniform Heating

Heating uniformity determines the steel plate induction heat treatment machine, and inductor calibration is the core procedure. During commissioning, the inductor shall be firmly fixed to keep a uniform gap between the inductor and the steel plate surface, avoiding local uneven heating caused by inconsistent spacing. Select matched inductor specifications and optimize installation angles and fitting distances according to the thickness, material and width of steel plates. In addition, test the insulation performance of the inductor to ensure qualified insulation resistance and prevent electric leakage and sparking faults. Standard calibration ensures stable magnetic field and uniform overall heating, effectively avoiding local overheating or insufficient heating defects.

3. Fine Adjustment of Process Parameters for Adaptable Processing

Steel plates with different materials and thicknesses cannot be processed with fixed parameters, which requires targeted and refined parameter debugging. The technical team of Forever Electromechanical optimizes three core parameters: heating power, heating time and running speed. For thick steel plates, properly extend heating time and reduce operating speed to ensure sufficient heat penetration and qualified hardened layer depth. For thin plates, adjust heating power to avoid surface overheating and plate deformation. Equipped with an infrared temperature measurement system, the equipment monitors real-time temperature and fine-tunes parameters dynamically according to thermal conductivity and austenitization rules, forming standardized process parameters suitable for various steel plates.

4. Sample Testing and Parameter Solidification for Mass Production

After preliminary parameter debugging, small-batch sample quenching tests are required to verify the processing effect. Technicians conduct hardness testing, hardened layer depth measurement and metallographic analysis to check for hardness deviation, uneven hardened layers and plate deformation. Slightly adjust power, cooling speed and operating rhythm according to test results, and repeat sample tests until all technical indicators meet standards. Qualified and stable process parameters are solidified to form a standardized operation scheme. Meanwhile, multiple protection functions including overvoltage, overheating and water shortage protection are activated to guarantee long-term stable equipment operation and meet the requirements of high-quality mass production.
