Industrial Quenching Furnace

A Industrial quenching furnace is a furnace used to heat workpieces before quenching. Quenching involves placing the workpiece inside the furnace and heating it to a quenching temperature above the critical point, holding it for a period of time, and then quickly removing the workpiece from the furnace and immersing it in a quenching solution (oil or water) for further quenching. The furnace's heat source can be electricity or fuel, and the temperature can be measured using thermocouples. Furnaces using electricity or gas/liquid fuels can have their temperature automatically controlled and regulated by instruments.

The core working principle of a Industrial quenching furnace is to achieve phase transformation strengthening of metal workpieces by precisely controlling the three process steps of heating, heat preservation, and rapid cooling, transforming the workpiece from its original structure into a hardened structure with high hardness and high wear resistance, thereby directionally improving the mechanical properties of the workpiece.

• Before quenching, extruded products can be heated uniformly and rapidly;
• The material can be immersed in the quenching tank in a short time;
• Bending and torsional deformation of extruded products due to their own weight and heat can Be avoided, which helps to maintain the shape of the products;
• The mechanical properties of extruded products are uniform after quenching.

• The Industrial quenching furnace is widely used in many fields:
• Automotive: Crankshafts, gears, chassis fasteners, shafts
• Die and Cutting Tools: Stamping dies, plastic molds, milling cutters, saw blades
• Construction Machinery and Mining: Bucket teeth, large gear rings, rolls
• Fasteners: Bolts, nuts, chains, springs
• Aerospace Precision Equipment: Titanium alloys, precision transmission components
• Medical Devices: Stainless steel surgical instruments
• Rail Transportation, Agricultural Hardware Tools

Furnace Shell: The furnace shell is the basic framework of the furnace and the foundation for implementing and controlling the quenching process.

Workpiece Support and Motion Devices: The workpiece support and motion devices inside the furnace ensure the correct movement of the workpieces and meet the requirements of the quenching process. Generally, motion devices are either rotary or linear.

Cooling System: The cooling system is an important component of the Industrial quenching furnace. Its main function is to rapidly cool the workpieces and maintain their microstructure.

Heating System: The heating system is the key technology for heating the workpieces inside the furnace to the quenching temperature. It mainly consists of a combustion system, heating elements, and a temperature control system.

Quenching Medium Supply System: The quenching medium supply system is another important component of the furnace. Its main function is to control the injection speed and direction of the medium, thereby ensuring the cooling quality of the workpieces.
