PRODUCT APPLICATIONS

Induction Hardening of Engineering Machinery Parts

Induction hardening is a widely used surface heat treatment process that enhances the durability and wear resistance of engineering machinery parts. By using electromagnetic induction to heat the surface of metal components, followed by rapid cooling (quenching), this method creates a hardened layer that significantly improves fatigue strength and performance under heavy-duty conditions.

PRODUCT APPLICATIONS

Induction Hardening for Automotive Parts

Induction hardening is a highly efficient heat treatment process widely used in the automotive industry to improve the durability and performance of critical components. By rapidly heating and then quenching the surface of metal parts, induction hardening increases hardness, wear resistance, and fatigue strength without affecting the core properties of the material.

PRODUCT APPLICATIONS

Induction Hardening of Tractor Parts

Induction hardening is a heat treatment process widely used to enhance the surface hardness and wear resistance of steel components. In the agricultural industry, particularly in tractors, this technique plays a critical role in extending the lifespan and performance of key parts subjected to high stress and friction. Components such as gears, axles, shafts, and pins benefit significantly from induction hardening, ensuring better durability and reliability in demanding field conditions.

PRODUCT APPLICATIONS

Motorcycle Parts Induction Hardening

Induction hardening is a critical heat treatment process used to enhance the durability and wear resistance of motorcycle parts. By applying high-frequency electromagnetic fields to heat the surface of metal components, followed by rapid quenching, induction hardening creates a hardened outer layer while maintaining a tough and flexible core.

PROCESS INTRODUCTION

Induction Hardening Process

01
Power Supply Activation

The induction power supply converts 50/60 Hz AC into high-frequency AC (typically 1–400 kHz) using solid-state inverters (IGBT/MOSFET).The output power (ranging from a few kW to several MW) is adjusted based on the hardening requirements.
02
Induction Coil Setup

A copper inductor coil (designed to match the part geometry) is placed near or around the workpiece.The coil carries the high-frequency current, generating an alternating magnetic field.
03
Eddy Current & Resistive Heating (Joule Heating)

The magnetic field induces eddy currents on the workpiece surface.Due to the material’s electrical resistance, these currents generate localized heat (skin effect).Heating occurs rapidly (within seconds) to austenitizing temperature (typically 750–1000°C for steel).
04
Quenching (Rapid Cooling)

Immediately after heating, the part is quenched using:Water;Polymer solutions (e.g., PAG);Oil (for alloy steels);This rapid cooling transforms austenite into martensite, creating a hard surface layer.
05
Tempering (Optional Post-Hardening Treatment)

Some applications require tempering to reduce brittleness while maintaining hardness.Done in a separate furnace or via induction reheating to a lower temperature (~150–400°C).
