Steel Billet Induction Heating and Reheating Furnace – Efficient Billet Reheating System

Introduction: Traditional Reheating Bottlenecks Restrict Steel Forming

Hot rolling and forging industries have raised higher requirements for billet temperature consistency, production flexibility and environmental compliance. Conventional gas-fired walking beam furnaces feature long heating cycles, large temperature deviation across billet sections, heavy oxide scale loss and delayed startup. They cannot adapt to frequent grade switching and small-batch flexible production. As a high-efficiency billet reheating system, the

steel billet induction heating machine adopts electromagnetic induction heating, bringing a reliable clean heating solution for steel rolling, forging and extrusion manufacturers.

Modular Continuous Structure for Stable Billet Heating

The continuous casting billet induction reheating machine applies a segmented modular coil design. It works with automatic feeding, centering conveying, multi-stage heating and discharging units. Square billets, round billets and continuous casting blooms are fed into the coil steadily. The IGBT medium-frequency power supply generates an alternating magnetic field to heat the billet from inside out. This internal heating mode avoids the surface overheating and core cold defects common in flame heating. The whole line can be used as a standalone furnace or a temperature compensation booster matched with existing furnaces, realizing seamless connection with rolling mills and forging presses.

Precision Temperature Control Reduces Oxidation and Improves Yield

Multi-channel infrared pyrometers are installed along the heating zone to collect real-time temperature data. The PLC closed-loop system dynamically adjusts power, conveying speed and heating curve according to steel grade and billet size. It keeps the temperature tolerance within a narrow range before rolling. Since the heating cycle is greatly shortened, the billet stays at high temperature for less time. Oxide scale loss is remarkably reduced, metal yield rises and surface decarburization is suppressed. Uniform cross-section temperature helps eliminate internal thermal stress, effectively lowering rolling cracking and forging defect rates.

Energy-saving and Eco-friendly Design for Low-carbon Steel Processing

Without open flame and fuel combustion, the induction reheating furnace produces no flue gas, NOx or sulfur emissions, simplifying environmental treatment facilities. Its thermal conversion efficiency is far higher than gas furnaces. It can start and stop instantly without long preheating and heat preservation, which avoids idle energy waste during intermittent production. The water-cooled coil and heat insulation structure cut heat dissipation. Operators set heating recipes on HMI for quick switching among carbon steel, alloy steel and special steel billets, greatly lowering labor intensity and operation cost.

Wide Application and Customized Service for Global Metal Forming

This efficient billet reheating system suits billet preheating for bar rolling, wire rod rolling, seamless pipe piercing and hot forging. It supports multiple billet sizes and alloy materials. Equipment layout, power configuration and feeding mode can be customized based on customer workshop space and production capacity. With stable running performance and convenient maintenance, the steel billet induction heating production line has become a preferred upgrade choice for many steel processing plants. It will continuously empower the transformation of metal forming industry toward high efficiency, clean production and intelligent manufacturing.
