Forever Electromechanical Delivers Custom‑Built Slab Induction Heating Machine for Overseas Steel Mill Real‑World Project

Project Background: Bottlenecks of Conventional Slab Reheating

Against global steel decarbonization trends, an important medium‑large steel rolling enterprise in Southeast Asia faced urgent upgrading demands for its slab reheating workshop. The customer mainly produces carbon steel and low‑alloy steel slabs for construction machinery and pressure‑vessel raw materials. Previously, the plant adopted traditional gas‑fired reheating furnaces for slab heating.

Old‑style combustion furnaces brought multiple operational pain points. Long heating cycles caused heavy surface oxidation and decarburization, creating large metal loss. Temperature deviation between slab surface and core was obvious, resulting in unstable mechanical performance of rolled finished products. In addition, high natural‑gas consumption brought rising production costs and large carbon emissions, making it hard to satisfy local environmental protection regulations and export material inspection standards. After technical comparison with several European and Asian equipment suppliers, the client finally chose Forever Electromechanical for a full‑set slab induction heating machine solution.

Core Technical Challenges Faced On‑Site

This real‑world overseas project contained several non‑negotiable technical difficulties. First, the local power grid had voltage fluctuation risks, which required the power supply system to resist grid interference. Second, the induction heat treatment machine needed to adapt to mixed feeding of hot‑charged and cold‑charged slabs, with slab thickness ranging from 120 mm to 260 mm. Strict requirements asked for overall heating uniformity within ±12 ℃ across slab cross‑section. Third, the workshop layout was limited; new induction equipment must seamlessly dock with the existing roller‑table and downstream rolling procedures without large‑scale civil reconstruction. Moreover, local on‑site operators lacked rich experience with large‑scale IGBT induction heat‑treatment devices, calling for simplified human‑machine interaction and complete remote technical support mechanism.

Forever Electromechanical Customized Solution

Forever’s overseas engineering and R&D team carried out targeted optimization based on actual working conditions. The slab induction heating machine
adopted high‑efficiency digital IGBT medium‑frequency power supply, improving power‑factor stability under fluctuating grid voltage. Multi‑group segmented induction coils were arranged according to slab width and thickness, realizing uniform internal‑external heating and restraining over‑heating of slab edges.

The full‑automatic PLC closed‑loop temperature control system connects with the original production line roller‑table, realizing automatic feeding, real‑time temperature monitoring and fault alarm. No major civil‑work modification was needed, greatly shortening installation cycle. The system reserves remote diagnosis interface for overseas after‑sales, matching multilingual operation screen for local staff. The whole line supports 24‑hour continuous heavy‑load operation, meeting the client’s target daily processing capacity of 220 tons of steel slabs.

Commissioning Operation & Measurable Project Benefits

After container transportation, on‑site assembly, 72‑hour full‑load hot commissioning, the slab induction heating machine was officially put into mass production. Actual operating data verified obvious comprehensive improvements. Unit power consumption per ton slab dropped by 27% compared with the original gas furnace. Slab surface oxidation‑decarburization rate decreased sharply, raising finished‑product yield significantly. Cross‑section temperature difference stayed within the design index, and rolled slab mechanical properties fully met export inspection requirements. Direct fossil‑fuel consumption was eliminated, helping the plant lower carbon footprint and satisfy local emission rules.

The client commented that Forever’s slab induction heating machine runs reliably, with convenient daily maintenance. Remote technical support greatly reduced overseas downtime losses. This real overseas case marks another solid achievement for Forever Electromechanical in global large‑section metal induction reheating field, demonstrating Chinese‑manufactured induction heat‑treatment equipment’s competitiveness on energy‑saving, customization and full‑cycle service. Going forward, Forever will keep optimizing slab, billet and plate induction heating solutions to serve more global metal processing customers pursuing green and efficient production
