The round steel induction heating furnace is a medium-frequency induction device specifically designed to heat round steel bars, operating on the principle of induction heating. It generates Joule heat within the steel through medium-frequency induction currents, thereby achieving the desired heating effect. Due to advantages such as high efficiency, environmental friendliness, and energy conservation, this heating method is widely used in the hot working and heat treatment of round steel.

I. Overview of the Round Steel Induction Heating Furnace:
1. The round steel induction heating furnace primarily consists of a thyristor-based medium-frequency power supply unit, an induction heating coil, feed/pressure rollers, an infrared temperature monitoring system, and a PLC control system. The thyristor medium-frequency power supply serves as the core power source for the equipment; it utilizes fully digital control to achieve adaptive thyristor frequency conversion and adaptive load handling. The induction heating coil features a variable-pitch design to establish a specific temperature gradient, thereby enhancing heating efficiency. The feed/pressure rollers allow for the adjustment of upper and lower roller positions, ensuring the uniform feeding of round steel bars of various diameters and guaranteeing heating consistency. An infrared temperature monitoring system tracks the discharge temperature to ensure that temperature variations remain within a ±20°C range.
2. The round steel induction heating furnace supports various applications, such as forging, quenching and tempering, and rolling of the heated steel. Precise control over heating temperature and duration allows the system to meet diverse processing requirements, ultimately improving product quality and production efficiency.
3. Operation of the round steel induction heating furnace begins with setting the heating temperature and duration according to the specific requirements of the workpiece. Next, the round steel to be processed is loaded into the furnace, and the heating process is monitored in real-time to ensure the target temperature is achieved.
