Abstract
The invention discloses a high-speed steel heat treatment process. The high-speed steel heat treatment process includes the following steps that A, surface hardening is conducted; B, carburizing and quenching are conducted; C, surface carburizing chemical heat treatment is conducted; D, hardening and tempering are conducted; and E, normalizing treatment is conducted. The high-speed steel heat treatment process has the beneficial effects that the structure performance of the structure surface can be greatly improved, and the tooth collapse phenomenon cannot be generated.
Description
Technical field
The invention belongs to technical field of heat treatment, particularly a kind of rapid steel thermal treatment process.
Background technology
At present, in prior art, in rapid steel heat treatment process, the intensity of hardened layer can be increased at a high speed through carbonitriding, but due to misoperation, surface layer excessive concentration may be caused, that the carbide of separating out is separated out with horn shape or netted form, tissue surface structure property can be caused seriously to reduce, easily produce tooth and collapse, and easy stress concentration.
Summary of the invention
Technical scheme of the present invention is achieved in that a kind of rapid steel thermal treatment process, comprises the following steps:
A, carry out hard surfacing;
B, carburizing and quenching;
C, surface carburization thermo-chemical treatment;
D, carry out modified;
E, normalizing treatment.
Preferably, in described steps A, after hard surfacing, tooth face hardness is generally 40 ~ 55HRC.
Preferably, in described step B, after carburizing and quenching, tooth face hardness can reach 56 ~ 62HRC.
Beneficial effect of the present invention: adopt the present invention that tissue surface structure property can be made greatly to be improved, tooth can not be produced and collapse phenomenon.
Embodiment
Embodiment provided by the invention is described in further detail:
A kind of rapid steel thermal treatment process, comprises the following steps:
A, carry out hard surfacing;
B, carburizing and quenching;
C, surface carburization thermo-chemical treatment;
D, carry out modified;
E, normalizing treatment.
Preferably, in described steps A, after hard surfacing, tooth face hardness is generally 40 ~ 55HRC.
Preferably, in described step B, after carburizing and quenching, tooth face hardness can reach 56 ~ 62HRC.
Beneficial effect of the present invention: adopt the present invention that tissue surface structure property can be made greatly to be improved, tooth can not be produced and collapse phenomenon.
In this description, the present invention is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification sheets is regarded in an illustrative, rather than a restrictive.
