Heat treatment of steel: definition of the process
Heat treatment – impact on the structural and phase state of the material using different modes of heating and cooling, in the process, which is achieved by the approach to equilibrium or a particular degree of deviation from it. Heat treatment provides a product of the required properties in the whole volume or part volume.
the Concept of modes of heating and cooling include the following characteristics: the speed of these processes, the temperature, the duration of isothermal curing.
heat treatment of steels are chosen with the account of phase and structural transformations in the material that is done with the aim of obtaining a list of required properties.
Heat treatment is preliminary and final. Pretreatment is used to prepare the structure and material properties to subsequent technological operations (to handle pressure, improve machinability). The properties of the finished product formed during final heat treatment.
the Thermal treatment used during the production of different materials and products, as well as in order to remove their tension. In addition to heat treatment, "Ukrenergoremont" more specializiruetsya and turning works.
Annealing and quenching are the main types of heat treatment of steel.
Heat treatment – this is the main way of influencing the properties of metals and alloys.
Heat treatment of steel consists of three stages
Every kind of heat treating steel consists of the following sequential steps:
- heated to the required temperature with a certain speed;
- extract for through warm-up and completion of structural transformations within the required time and at a predetermined temperature;
- cooling at a certain speed (more or less).
the Measurement of these factors determines the properties of steel.
Heat treating steel must only be performed by professionals because improper carrying out heat treatment, can significantly reduce the quality of the steel. Therefore, refer to the "Ukrenergoremont" which is also specializiruetsya milling works, welding etc.
the misconceptions of the heat treatment implies a deviation from the established regime, namely the lack of heating steel, low speed cooling, warpage, overheating quenching cracks, decarburization.
