Steel Billet Heating and Reheating Furnace: High-Efficiency Induction Heating Solution | Forever Electromechanical

Introduction

Steel billet heating and reheating furnace is the core thermal processing equipment for steel forging, rolling and extrusion production. It is mainly used for uniform heating and secondary reheating of carbon steel, alloy steel and special steel billets before hot working. Traditional flame heating furnaces suffer from low efficiency, severe oxidation, uneven temperature and high carbon emissions. To solve these industrial pain points, Forever Electromechanical has independently developed a new generation of induction-type steel billet heating and reheating furnace, delivering energy-saving, high-precision and fully automatic heating solutions for global metal processing enterprises.

Industry Pain Points of Traditional Heating Equipment

In the steel processing industry, billet heating quality directly determines the mechanical properties and yield of finished products. Conventional gas-fired and resistance reheating furnaces have long restricted factory production upgrades. First, external radiation heating leads to huge heat loss and low electrothermal conversion efficiency, resulting in high power and fuel consumption. Second, serious temperature difference exists between the billet surface and core, causing unstable forging quality and high product rejection rate. Third, long-time high-temperature heating produces thick oxide scales, wasting raw materials and affecting surface finish. In addition, traditional furnaces require long preheating time, cannot start and stop flexibly, and fail to adapt to modern intelligent and intermittent production modes.

Core Technical Advantages of Forever Electromechanical Furnace

Forever Electromechanical’s steel billet heating and reheating furnace adopts advanced IGBT intermediate-frequency induction heating technology, generating heat inside the steel billet through electromagnetic induction and eddy current heating. This internal heating method completely changes the limitations of traditional external heating. The equipment realizes rapid heating without preheating, with heating efficiency far exceeding traditional furnaces, effectively reducing comprehensive energy consumption.

The furnace adopts segmented temperature control and closed-loop infrared detection system, achieving precise temperature control within ±3℃. It ensures uniform heating from surface to core of steel billets, thoroughly solves the problem of inconsistent metallurgical structure, and greatly improves the toughness and stability of forged and rolled products. Meanwhile, the fast heating speed shortens high-temperature exposure time, significantly reducing oxide scale and decarburization, which improves material utilization rate by 3%–5%.

Automatic and Green Production Performance

Designed with modular integration and full automation, the heating and reheating furnace supports automatic feeding, constant-temperature reheating, real-time data monitoring and intelligent discharging. It can match 24-hour continuous production lines of steel balls, steel bars and steel pipes, effectively reducing manual intervention and labor costs. Equipped with high-density thermal insulation materials, the equipment minimizes heat radiation loss and improves overall operating safety.

Different from fuel furnaces that produce exhaust pollution, Forever’s induction reheating furnace features zero emission, low noise and low energy consumption, fully complying with global industrial low-carbon and environmental protection standards. It is an ideal upgraded replacement for traditional heating equipment for metal forging and hot rolling.

Application and Market Value

This steel billet heating and reheating furnace is widely applicable to heating and reheating processes of various round and square steel billets, covering mining grinding balls, construction steel bars, petroleum pipes and other metal processing fields. With stable operation, simple maintenance and flexible production switching, it adapts to both mass standardized production and customized small-batch processing.
