Electric steel bar induction heating furnace

steel bar heat treatment production line is an industrial equipment that uses electrical energy to rapidly heat steel bars. Electric furnaces use resistance heating or induction heating technology to convert electrical energy into thermal energy, rapidly increasing the temperature of steel bars for subsequent process operations. This device is widely used in forging heating, rolling heating, and heat treatment processes, and is a core equipment in the field of modern industrial metal heating.

Working principle of steel steel bar induction heating furnace

Steel bar heating electric furnaces are mainly divided into two types: resistance heating furnaces and induction heating furnaces, and their working principles are different

Principle of Resistance Heating

A resistance heating furnace generates heat through resistance wires, similar to the principle of a household electric oven. When current passes through the resistance material (such as nickel chromium alloy) in the furnace, the resistance material generates heat, which is then transferred to the steel rod through thermal radiation and conduction.

Principle of Induction Heating

steel bar induction heating furnace is based on the principle of electromagnetic induction, which forms an alternating electromagnetic field by passing medium frequency or high-frequency alternating current into the induction coil. The steel rod is placed as a conductor in a magnetic field, inducing eddy currents. The eddy currents generate heat through the resistance of the steel rod itself, thereby achieving rapid and uniform heating.

Steel bar heating electric furnace is an important equipment in the metal hot processing industry. With its high heating efficiency, environmental protection and energy-saving characteristics, it is widely used in forging, rolling and heat treatment processes. Through advanced electromagnetic induction or resistance heating technology, steel bars can quickly and uniformly heat up, meeting the high-quality requirements of modern production.
