Tempering Furnace

This tempering furnace is designed for independent operation or seamless integration into fully automatic heat treatment production lines.
The primary function of the equipment is to effectively eliminate internal stresses from the quenching process, optimizing the balance between hardness, toughness, and plasticity to enhance wear resistance and service life.
It demonstrates exceptional processing versatility, accommodating plate thicknesses from 1mm to 500mm, lengths up to 12,000mm, and widths up to 4,000mm, suitable for a wide range of component specifications.
With design power ranging from 10kW to 2,000kW, the system maintains high temperature precision between ±2°C and ±5°C and supports protective atmospheres like nitrogen or argon to prevent oxidation and ensure surface quality.
Engineered for energy efficiency and uniform heating, the furnace features multiple induction opening configurations—including single-sided, double-sided, and adjustable options—with production cycles flexible between 10 and 180 minutes.

Advantages of tempering furnaces:
Stress relief: Tempering can effectively remove the internal stress generated during quenching, preventing the metal from cracking or deforming during subsequent processing.
Improved toughness and ductility: Tempered metals have better toughness and ductility, making them suitable for making parts that require high toughness.
Optimize hardness: Tempering can bring the hardness of metal to a balance point, neither too hard nor too soft, which is suitable for parts that require high strength and wear resistance.
Improved wear resistance: Tempered metal materials are more wear-resistant and can extend their service life.
Energy-saving and environmentally friendly: Modern tempering furnaces have been optimized in terms of energy consumption, making them more energy-efficient than traditional furnaces. They also have a better temperature control system, reducing exhaust emissions.

Common parameters of tempering furnaces:
Operating temperature: The tempering temperature is generally between 150℃ and 650℃, depending on the type of metal material and requirements.
Temperature control accuracy: Precise temperature control can ensure the tempering effect. Common temperature control accuracy is ±2℃ to ±5℃.
Heating methods: Common heating methods include electric heating, gas heating, and coal heating. Modern industry typically uses electric heating and gas heating.
Furnace capacity: The capacity of tempering furnaces can vary depending on the usage requirements. Common capacities include 100L, 200L, and 500L, while larger industrial-scale furnaces can have capacities of 1000L or more.
Heating uniformity: To ensure a good tempering effect, heating uniformity is very important. The furnace is usually designed with multiple temperature control points to ensure that heating is uniform in all parts.
Cooling methods: Cooling systems are generally divided into natural cooling, air cooling and water cooling, etc. Choosing the right cooling method can affect the properties of the metal after tempering.
Furnace atmosphere: Some tempering furnaces use protective atmospheres such as nitrogen and argon to prevent oxidation and improve workpiece quality.
