Long bar induction hardening and tempering line

The long bar induction hardening and tempering line is indeed an efficient solution for heat treatment of workpieces such as long rod materials and bolts. Its core advantages are automation, high efficiency, and stable quality, making it particularly suitable for large-scale production.

Core strengths

Automated continuous production: The entire process from loading to unloading is automated, reducing manual intervention and improving efficiency and consistency.

Efficient and energy-saving: Induction heating directly heats the workpiece with minimal heat loss and low energy consumption.

Stable quality: Accurate temperature control and cooling system ensure uniform hardness, minimal deformation, and high product qualification rate.

Wide applicability: It can handle steel bars with a diameter of 20-300mm and a length of several meters, and is compatible with various materials.

Loading: The workpiece is automatically loaded and transported to the heating zone.

Hardening heating: Induction heating to austenitization temperature (usually 850-950 ℃).

Hardening cooling: rapid cooling with water or oil spray to form martensitic structure.

Tempering heating: Induction heating to the tempering temperature (usually 500-650 ℃).

Tempering cooling: Natural cooling or forced cooling to obtain the required mechanical properties.

Cutting: The finished product is automatically cut and collected.

key equipment

Induction heating power supply: Medium frequency or high-frequency power supply, providing stable heating power.

Induction heater: customized according to the shape of the workpiece to ensure uniform heating.

Hardening cooling system: spray water or spray oil cooling, control cooling speed.

Tempering heating system: Induction or resistance heating, precise control of tempering temperature.

Conveyor system: roller conveyor or chain conveyor, achieving continuous production.

Control system: PLC or industrial computer, integrated monitoring and data recording.

Applicable scenarios
