Medium frequency casing steel billet induction reheating process

Main technical parameters of steel billet reheating furnace:

● Applicable workpieces: Suitable for reheating of steel billets, square billets, square steel, continuous casting billets, slabs, etc.

● Power supply system: Dual rectifier 12 pulse or 24 pulse 1000-12000KW/500-1200Hz, single power supply can be used independently or multiple power supplies can be used in parallel; The hourly output is 40-300 tons.

● Applicable range: 120mm~160mm square billet, length 3000mm~12000mm.

● Feeding system: Each axis is driven by an independent motor reducer, with multiple axis drives set up and controlled by a single frequency converter to synchronize the operation of multiple axes.

● Guidance system: using 304 non-magnetic stainless steel guide wheels, and maintaining moderate elasticity in the axial direction of the guide wheels to adapt to the allowable bending range of the steel billet.

● Temperature closed-loop system: A closed-loop control system composed of Leitai infrared thermometer and Siemens S7, which automatically adjusts the power supply according to the initial temperature and feed rate of the steel billet entering the sensor, so as to maintain a constant heating temperature before it is discharged from the furnace.

● Energy conversion: Depending on the surface temperature of the steel billet, the power consumption per ton of steel is 40-60 degrees

Advantages and characteristics of steel billet hot rolling heating furnace:

●If a steel billet hot rolling induction heating furnace is used in the steel billet hot processing workshop, the workshop temperature is greatly reduced due to less heat loss, which improves the working conditions in the workshop. Due to the fact that the induction heating process for hot-rolled steel billets does not produce smoke or dust during the processing of workpieces, it purifies the working environment of the workshop and meets the requirements of energy conservation and environmental protection in the new era.

●In terms of electric heating for production equipment, resistance furnaces are rarely used for heating raw materials before hot forming because the heating temperature of the raw materials is relatively high and limited by electric heating elements. Therefore, induction heating is mainly used. Induction heating of raw materials before hot forming has been used in processes such as forging, hot stamping, hot extrusion, and hot cutting of raw materials.
