Abstract

The invention discloses a metal heating processing technology. The technology comprises the following steps: heating metals in a high frequency induction heating machine, wherein the high frequency induction heating machine is in a vacuum state and the temperature in the high frequency induction heating machine is higher than 1400 DEG C; maintaining the metals in the high frequency induction heating machine at 1400 DEG C for a certain period to ensure the internal and external temperatures to be consistent and the microstructures in the metals to be completely transformed; and taking out the metals, insulating the metals at a proper temperature higher than the room temperature and lower than 650 DEG C for a longer period and then cooling the metals. The technology has the advantages of convenience in operation, time and labor saving and improvement of work efficiency.

Description

A kind of metal heat treatmet technology
Technical field:
The present invention relates to a kind of metal heat treatmet technology.
Background technology:
Nowadays; Metal heat treatmet is one of significant process in the machinofacture; Compare with other complete processings, thermal treatment does not generally change the shape and whole chemical ingredients of workpiece, but through changing the microstructure of interior; Or change the chemical ingredients of workpiece surface, give or improve the use properties of workpiece.Be characterized in improving the inner quality of workpiece, and this generally not to be naked eyes can see, so it is the special process process in the machinofacture, also be the important step of quality control.For making metal works have needed mechanical property, physicals and chemical property, except that reasonable select materials and various forming technology, thermal treatment process is requisite often.Iron and steel is to use the widest material in the mechanical industry, and microstructure of iron and steel is complicated, can control through thermal treatment, so the thermal treatment of iron and steel is the main contents of metal heat treatmet.In addition, aluminium, copper, magnesium, titanium etc. and alloy thereof also can change its mechanics, physics and chemical property through thermal treatment, to obtain different use propertieies.During METAL HEATING PROCESS, workpiece is exposed in the air, and oxidation, decarburization (being that the steel-iron components carbon contents reduces) usually take place, this for thermal treatment after the surface property of part very adverse influence is arranged.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, a kind of easy to operate, time saving and energy saving, metal heat treatmet technology of increasing work efficiency is provided.
The object of the invention is realized through following technical scheme: a kind of metal heat treatmet technology may further comprise the steps:
A, heating: metal is put into the high-frequency induction heating machine heat, be in the state of vacuum in the high-frequency induction heating machine, and temperature inside is higher than 1400 ℃;
B, insulation: let metal in the high-frequency induction heating machine of said temperature, keep certain hour, make internal and external temperature consistent, the microstructure in the metal is changed fully;
C, cooling: metal is taken out, and be lower than 650 ℃ a certain proper temperature being higher than room temperature and carry out the insulation of long period, cool off again.
The present invention compared with prior art has the following advantages:
Metal heat treatmet is metal works to be placed on be heated to suitable temperature in certain medium; And after in this temperature, keeping certain hour; Cool off in different media with friction-motion speed again, control a kind of technology of its performance through changing metal material surface or inner microstructure.
Embodiment:
In order to deepen to understanding of the present invention, will combine embodiment that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
A kind of embodiment of a kind of metal heat treatmet technology of the present invention, thermal treatment process generally comprise heating, insulation, three processes of cooling, and these processes overlap, and can not be interrupted, and may further comprise the steps:
A, heating are one of heat treated important procedures: metal is put into the high-frequency induction heating machine heat; Be in the state of vacuum in the high-frequency induction heating machine; And temperature inside is higher than 1400 ℃; Heating temperature is one of important technical parameter of thermal treatment process, selects and the control Heating temperature, and be the subject matter that guarantees thermal treatment quality.Heating temperature is different and different with the thermal treatment purpose with the metallic substance that is processed, but generally all is to be heated to certain more than the characteristic transition temperature, to obtain high temperature microstructure;
B, when the metal works surface meets the requirements of Heating temperature, also must keep certain hour in this temperature, make internal and external temperature consistent, microstructure is changed fully, be called soaking time during this period of time;
C, cooling also are indispensable steps in the heat treatment process; Method of cooling is different because of technology; Mainly be controlled chilling speed: metal is taken out, and be lower than 650 ℃ a certain proper temperature being higher than room temperature and carry out the insulation of long period, cool off again.
Complete heat treatment is to the whole workpiece heating, then with suitable speed cooling, to change the metal heat treatmet technology of its whole mechanical property.Thermal treatment is one of important procedure in mechanical component and the tool and mould manufacturing processed.It can guarantee and improve the various performances of workpiece, as wear-resisting, corrosion-resistant etc., can also improve the tissue and the stressed condition of blank, is beneficial to carry out various hot and cold processing.
