What is conditioning?quenching and tempering heat treatment production line is defined as the double heat treatment of quenching and tempering.
1, the purpose of tempering and tempering treatment: to make the workpiece have good comprehensive mechanical properties.
2. High temperature tempering: refers to tempering between 500 and 650 ℃.
3. the effect of quenching and tempering: the properties and materials of the steel are adjusted to a great extent, the strength, plasticity and toughness of the steel are better, and it has good comprehensive mechanical properties.
4. Steps for quenching and tempering:
(1) the first step: quenching, heating temperature depending on the composition of steel, quenching medium is selected according to steel hardenability and steel size.
(2) the second step: tempering is to normalize the mechanical properties of quenched and tempered steel in order to relieve stress, increase toughness and adjust strength.
5, quenching and tempering applications: automotive shafts, gears, aero-engine turbine shafts, compressor disks, etc.
