Background technology
Heat treatment is one of important process in machine-building, and compared with other processing technologys, heat treatment does not change typically
The shape of workpiece and overall chemical composition, but by changing the microscopic structure of inside workpiece, or change the change of workpiece surface
Study point, assign or improve the performance of workpiece, be characterized in improving the inherent quality of workpiece, and this is generally not naked eyes institute
It can see.To make metal and material work piece that there is required mechanical property, physical property and chemical property, except reasonable selection
Outside material and various forming technologies, Technology for Heating Processing is often essential.Metal is material most widely used in mechanical industry
Material, metal microstructure is complicated, can be controlled by heat treatment, so the heat treatment of metal is the main interior of heat treatment
Hold；In addition, aluminium, copper, magnesium, titanium etc. and its alloy also can change its mechanics, physical and chemical properties by being heat-treated, to obtain
Obtain different performances.Technology for Heating Processing generally comprises three heating, insulation, cooling processes, only heats and cools down sometimes
Two processes, these processes overlap, and can not be interrupted.
The Technology for Heating Processing of existing 17Cr16Ni2 materials is quenched+surface induction hardening, and quenched hardening heat control exists：
980 ± 10 DEG C, the temperature control of quenched tempering is at 650 ± 30 DEG C；Due to subsequently there is impewdance matching process, impewdance matching has heat
The chemical composition of zone of influence material in addition is unstable, can be impacted as this technological operation absorb work(will as defined in less than standard
Ask.
The content of the invention
The present invention is exactly in view of the deficienciess of the prior art, provide a kind of heat-treatment technology method, is formd a kind of new
Heat-treatment technology method so that product heat treatment performance has reached technical requirements, meets actual operation requirements.
To solve the above problems, the technical solution used in the present invention is as follows：
A kind of heat-treatment technology method, it is that quenched and surface induction is quenched that Technology for Heating Processing is mainly carried out to 17Cr16Ni2 materials
Fire, its concrete technology method are as follows：
Step（1）, quenched quenching：17Cr16Ni2 materials match it is quenched after, then carry out surface induction hardening processing；
Step（2）, once quenched tempering：To step（1）17Cr16Ni2 materials after processing once matched it is quenched, and together
The processing of Shi Jinhang one-time surfaces induction tempering；
Step（3）, secondary quenched tempering：To by step（2）The secondary proportioning of 17Cr16Ni2 materials progress of processing is quenched, and
Secondary surface induction tempering processing is carried out simultaneously.
As the improvement of above-mentioned technical proposal, step（1）Described in the temperature control of quenched quenching exist：980±10℃；Step
Suddenly（2）Described in the temperature control of once quenched tempering exist：980±10℃；Step（3）Described in secondary quenched tempering temperature
Control exists：650±30℃.
Compared with prior art, implementation result of the invention is as follows by the present invention：
The present invention is by being optimized to the hardening and tempering process in quenched heat treatment step, in original quenched quenching, quenched tempering
Double tempering is being carried out afterwards, the precipitation of carbide is being reduced, so as to improve the impact flexibility of bolt, meets actual operation requirements.
