We know that in order to obtain high performance and high quality of metal work-piece, it is necessary to carry out Metal heat treatment furnace, change the surface micro-structure of metal steel, improve its strength, hardness, bending strength, service life and so on.
Metal heat treatment is a process in which the metal work-piece is heated to a suitable temperature in a certain medium and kept in this temperature for a certain period of time and cooled at different speeds. Metal heat treatment is to give or improve the performance of the work-piece by changing the micro-structure of the work-piece or changing the chemical composition of the surface of the work-piece. It is characterized by improving the internal quality of the work-piece, which is generally not visible to the naked eye.
Quenching and tempering are closely related and often used in conjunction with each other. In order to obtain a certain strength and toughness, quenching and high temperature tempering process is called quenching and tempering. After quenching to form supersatured solid solution, some alloys are kept at room temperature or slightly higher for a long time in order to improve the hardness, strength or electrical magnetism of the alloy.
Heat treatment is to heat the material to a certain temperature, heat preservation for a certain time, at a certain rate, cooling to room temperature or lower, so as to improve the microstructure of the material, in order to obtain excellent properties of the material. Generally refers to the metal material, especially the “steel” treatment.
The heat treatment method of high temperature tempering after quenching is called quenching and tempering treatment. High temperature tempering refers to tempering between 500 ℃ and 650 ℃. The properties and materials of the steel can be adjusted to a great extent by quenching and tempering, and its strength, plasticity and toughness are good, and it has good comprehensive mechanical properties. Tempered sorbite was obtained after tempering and tempering treatment.
