High Temperature Tempering Furnace Price Quenching and Tempering Heat Treatment Equipment Electric Screw Tempering Furnace
Tempering furnace is a heat treatment device used to heat, hold, and cool quenched metal workpieces at temperatures below the critical temperature. Its core purpose is to eliminate quenching stress, stabilize the microstructure and dimensions, and adjust hardness and toughness to give the workpiece the final performance required for its intended use.
Product Advantage
1. Eliminating quenching stress – ensures dimensional stability, prevents cracking, and extends service life.
2. Adjusting hardness and toughness – achieves a "strength-toughness balance" to meet specific operating conditions (e.g., high elasticity for springs, sharpness and non-chipping for cutting tools).
3. Stabilizing microstructure and dimensions – prevents deformation of precision parts (bearings, molds) during long-term storage or use.
4. High temperature uniformity – ensures consistent tempering quality across the entire furnace, resulting in a low scrap rate.
5. Atmosphere compatibility – allows for use in various environments including air, protective atmosphere, and vacuum.
