steel plate induction hardening furnace is a device used for hardening steel plates. hardening is a heat treatment process that involves rapidly cooling and heating a metal to an appropriate temperature to alter its microstructure and properties.
Classification of steel plate induction hardening furnaces:
1. Salt bath induction hardening furnace: using a molten salt bath to harden steel plates.
2. Gas induction hardening furnace: Hardening is achieved by placing steel plates in a high-speed airflow and rapidly cooling them.
3. Liquid induction hardening furnace: using liquid media such as water or oil for hardening.

Working principle of steel sheet plate induction quenching machine:
1. Heating stage: The steel plate is first heated to an appropriate temperature to achieve the required crystal structure for hardening.
2. Hardening stage: The steel plate is quickly placed in a cooling medium to rapidly cool it, change its crystal structure, and increase its hardness.
3. Tempering stage: It may be necessary to temper the hardened steel plate to reduce its brittleness.
Steel plate induction hardening furnace operation:
1. Set process parameters: including heating temperature, holding time, hardening medium, etc.
2. Loading steel plate: Place the steel plate to be processed in the hardening furnace.
3. Monitoring process: Real time monitoring of temperature, time, and other key parameters to ensure that the hardening process is carried out according to requirements.
4. Unloading and processing: Remove the hardened steel plate from the furnace and may undergo further processing, such as tempering.
steel plate induction hardening heating machines are widely used in industries such as automotive, aerospace, engineering machinery, and tool manufacturing.
