Automatic Feeding & Pre-inspection

The entire working process starts with automatic feeding and pre-inspection. Equipped with intelligent conveying and detection system, the induction billet heater realizes automatic sorting and feeding of steel billets. Before heating, the system automatically detects the specification, length and surface state of each billet, eliminating unqualified workpieces. The PLC control system accurately matches the optimal heating parameters according to different steel materials and billet sizes, laying a foundation for standardized and consistent heating quality, avoiding manual operation errors and improving overall production stability.

Electromagnetic Induction Rapid Heating

This is the core working link of the high-efficiency induction billet heater. The equipment generates a stable alternating electromagnetic field through the IGBT intermediate frequency induction heating power supply and induction coil. When the steel billet passes through the coil at a constant speed, eddy currents are generated inside the metal. Relying on the self-resistance of steel materials, internal heat is quickly converted, realizing internal and external synchronous heating. Different from external heating modes, this non-contact heating method features fast temperature rise, no open flame and minimal surface oxidation, effectively avoiding billet surface decarburization and deformation problems.

Segmented Constant Temperature & Precision Temperature Control

To ensure uniform heating quality, the equipment adopts segmented gradient heating and constant temperature insulation technology. The heating area is divided into preheating section, rapid heating section and constant temperature homogenization section. The infrared closed-loop temperature measurement system monitors the billet temperature in real time and feeds back data to the control system dynamically. The equipment automatically adjusts power output and conveying speed to keep the temperature difference of the billet within an ultra-small range. It thoroughly solves the common problem of inconsistent internal and external temperature of traditional heating, fully meeting the precise temperature requirements of subsequent forging and extrusion processes.

Automatic Discharging & Intelligent Protection

After reaching the preset process temperature, the uniformly heated steel billets are automatically output through the roller conveying system and sent to the forging or pressing station in real time. The whole process runs continuously and unmanned, greatly improving production efficiency. Meanwhile, the equipment is equipped with multiple safety protection mechanisms including overcurrent, overvoltage, overheating and water shortage protection. Once abnormal working conditions occur, the system will automatically alarm and stop operation, ensuring long-term stable and safe continuous production.
