The complete set of horizontal medium frequency induction heating equipment includes components such as medium frequency power supply cabinet (KGPS/IGBT optional), compensation capacitor bank, horizontal induction furnace body, circulating water cooling system, horizontal conveying mechanism, infrared temperature control device, operation control cabinet, etc. It is suitable for integral or sectional heating of carbon steel, alloy steel, copper and aluminum profiles, various alloy round steels and steel pipes, featuring fast heating speed, wide adjustable temperature range and low workpiece burning loss, and is compatible with continuous heat treatment operation of assembly lines.

Non-standard equipment with corresponding power, furnace chamber length and conveying speed can be customized based on the workpiece diameter, length, heating temperature and hourly output.

Core Features

• Convenient loading and unloading: With horizontal layout, workpieces are placed and conveyed horizontally. Loading and unloading of long bars and pipes is simple, and it is easy to connect with roller tables and pushers to realize automatic assembly line docking.
• Excellent energy consumption performance: Adopting medium frequency variable frequency induction heating technology, the electric energy conversion loss is low, which is improved compared with gas furnaces and resistance furnaces; the closed furnace chamber reduces heat dissipation and lowers the workshop temperature.
• Uniform heating of workpieces: The induction coil is arranged transversely along the workpiece, the axial and radial temperature difference of long profiles is small, which reduces the problems of local overburning and uneven temperature, and stabilizes the heat treatment quality of workpieces.
• Equipped with magnetic shielding structure: Magnetic shielding components are added to the furnace body to reduce magnetic field leakage, lower electromagnetic interference, and ensure the stable operation of the equipment and surrounding electronic control components.
• Digital intelligent control system: Integrated with a digital control panel, heating power, conveying speed and heat preservation time can all be adjusted. Equipped with real-time monitoring via infrared temperature measurement, it is convenient to solidify standardized production processes.
• Complete water cooling structure: The induction coil and furnace frame are equipped with circulating water cooling to continuously dissipate working heat, delay coil aging, and support long-term continuous operation of the equipment.
• Non-standard customization for multiple specifications: Furnace length, equipment power and fully automatic conveying mechanism can be customized according to workpiece material, cross-section size and heat treatment process.
• Continuous automatic conveying: Equipped with horizontal roller table pushing mechanism, workpieces move transversely at a constant speed, and can be directly docked with forging equipment and quenching tanks to form an integrated automatic production line.
• Simple adjustment for production change: Supports no-load start, no need for long preheating. It is convenient to debug when replacing workpiece specifications and processing categories, and is suitable for alternate production of multiple varieties.

Working Principle

The horizontal medium frequency induction heating furnace is based on the principle of electromagnetic induction heating, following the law of electromagnetic induction e=W*-dΦ/dt. The medium frequency power supply converts power-frequency alternating current into medium-frequency alternating current, which is fed into the horizontally wound induction coil to generate an alternating magnetic field; the magnetic field passes through the horizontally placed metal workpiece, and induced eddy current is generated inside the workpiece. Joule heat is generated by virtue of the metal's own resistance, so as to realize uniform penetration heating of the workpiece from the inside out, and complete heat treatment processes such as forging preheating, quenching and tempering, with fast heating response and good heat energy utilization.
