Have you selected the right steel bar quenching and tempering line?

The iron and steel machinery industry is closely related to the induction heating industry, and the steel bar quenching and tempering production line plays an important role in its production process. The quenching and tempering process of steel bar is an important prerequisite to ensure the quality of steel and other metal parts.

FOREVER mechanical and electrical steel bar quenching and tempering treatment equipment replaces oxyacetylene flame, coke furnace, salt bath furnace, gas furnace, oil furnace and other heating methods. The equipment is safe and reliable, energy saving and environmental protection, and high production efficiency.

The hot rolled bar treated by medium frequency induction heating and tempering, quenched to very fine martensite by rapid heating of austenite, and tempered at high temperature to obtain fine tempered sorbite. This tempered sorbite has high tensile strength and yield strength, as well as good statue and toughness. The metal workpiece after quenching and tempering process has good comprehensive mechanical properties.

FOREVER mechanical and electrical steel bar quenching and tempering production line is light in weight, small in size and simple in installation. It can be completed in a few minutes by connecting 380V three-phase power supply, water inlet and water outlet. It covers a small area and is easy to operate. It can be learned in a few minutes.

Automatic control type can adjust heating time, heating power, heat preservation time, heat preservation power and cooling time; It greatly improves the quality of heating products and the repeatability of heating, and simplifies the operation technology of workers.

Especially safe, the output voltage is lower than 36v, avoiding the danger of high voltage electric shock.

The equipment has perfect automatic protection functions such as over-current, over-voltage, over-temperature, water shortage and water shortage, and is equipped with fault self-diagnosis and emergency signal system.

The heating efficiency is as high as 90%, and the energy consumption is only 20% – 30% of the high frequency of the old electronic tube. In standby mode, there is almost no electricity, and it can work continuously for 24 hours.


The inductor can be disassembled and replaced freely and quickly, and the ultra-fast heating greatly reduces the oxidation deformation of the workpiece.

With the development of science and technology, the steel bar quenching and tempering treatment line has been widely used. FOREVER mechanical and electrical steel bar quenching and tempering treatment line has won customers and market by using the advantages of induction heating technology and green energy saving. FOREVER electromechanical steel bar quenching and tempering treatment equipment can greatly reduce heat loss and energy loss, increase production efficiency for users and improve product quality. Are you right about “steel bar quenching and tempering treatment equipment”!

Our company also has other machines: steel bar hardening and tempering production line 、Steel ball induction forging furnace 、steel tube induction preheating furnace 、medium frequency furnace  、steel billet induction reheating furnace 、metal heating forging furnace 、square billet heating furnace and so on.

Welcome to call to inquire about the furnaces details.
