Steel Billet Reheating Furnace For Forging Process

May. 27, 2026

The Steel Billet Reheating Furnace is the core thermal processing equipment specially designed for the preheating and forging process of various steel billets, widely applied in metal forging, hardware manufacturing, mechanical parts processing, and metallurgical industries. It serves as essential pre-processing equipment before steel billet forging, rolling, and stamping, playing a decisive role in improving forging quality, optimizing processing efficiency, and reducing production costs for forging enterprises.

Different from traditional resistance heating and flame heating equipment, this reheating furnace adopts advanced medium-frequency induction heating technology, which realizes rapid and non-contact heating for solid steel billets such as carbon steel, alloy steel, stainless steel, and structural steel. The equipment can uniformly heat the whole body or fixed local positions of steel billets according to the forging process requirements, effectively solving the common problems of traditional furnaces, including slow heating speed, uneven internal and external temperature, serious oxidation and decarbonization, and large heat loss.

billet forging heat treatment process

In the standard forging production process, cold steel billets need to reach a specific plastic forming temperature through uniform heating before forging processing. The steel billet reheating furnace can accurately control the heating temperature within the optimal forging temperature range of 1100℃ to 1250℃. The precise constant-temperature control system ensures consistent temperature of the billet surface and core, avoiding the forging defects such as cracking, deformation, and uneven material density caused by temperature difference. The heated steel billets have good metal plasticity and low deformation resistance, which greatly reduces the working load of forging hammers and presses, and extends the service life of forging equipment and molds.

This reheating furnace supports continuous and batch automatic production, matching the assembly-line forging production mode. It is equipped with an intelligent feeding and discharging system, which can realize automatic feeding, constant-temperature heat preservation, quantitative discharging and fault alarm. The whole production process does not need excessive manual intervention, effectively improving production efficiency and reducing labor costs. Compared with traditional coal-fired and gas-fired furnaces, the induction reheating furnace has no open flame combustion, no waste gas and smoke emission, completely meeting modern environmental protection production standards and solving the environmental pressure of forging factories.

In terms of energy consumption and operation performance, the equipment has outstanding advantages. The induction heating mode directly converts electric energy into thermal energy inside the steel billet, with high thermal conversion efficiency and little heat dissipation loss. It can save more than 30% of energy consumption compared with traditional heating equipment. Meanwhile, the equipment starts quickly, heats up fast, and can reach the set temperature in a short time without preheating and heat preservation for a long time, which greatly shortens the production cycle and improves the factory’s daily output.
