Abstract
The invention relates to a treatment process and mainly relates to large load gears. The process is characterized in that the process includes the following steps that A, high-frequency induction heating is performed, specifically, high-frequency induction heating is performed at the temperature of 860-900 DEG C, and heat preservation is conducted for three hours; B, quenching is performed, specifically, a gear after being subjected to induction heating is put in water for quenching for one hour; and C, tempering is conducted, specifically, the quenched gear is put in a tempering furnace for tempering treatment, the furnace temperature rises to 590-625 DEG C, heat preservation is performed for five hours, and the treated gear is discharged out of the furnace and air-cooled to room temperature. By means of the treatment process, heating is more completely performed, and the interior tenacity of the gear is improved.
Description
Technical field
The present invention relates to a kind of process technique, relate generally to big load gear.
Background technology
If existing gear pressure work when is excessive, or practicality is more frequent, is easy for causing the damage of gear,
Make between gear can not well toe joint together, and, gear is all in inside, and the most bad replacing, this results in existing gear
In application, gear is had the highest requirement.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of heat treatment work of offer
Skill, the heating of this Technology for Heating Processing is more complete, makes the toughness of gear internal improve.
For achieving the above object, the invention provides a kind of process technique, it is characterised in that comprise the steps:
A, high-frequency induction heating: 860～900 DEG C of high-frequency induction heating, be incubated 3 hours；
B, quenching: the gear after sensing heating is put in water and quenches, 1 hour time；
C, tempering: being put into by gear in tempering furnace and carry out temper, furnace temperature rises to 590-625 DEG C, be incubated 5 hours, come out of the stove
Air cooling is to room temperature.
The invention has the beneficial effects as follows: present invention heating is more complete, makes the toughness of gear internal improve.
Detailed description of the invention
Technical scheme disclosed by the invention is a kind of Technology for Heating Processing, it is characterised in that comprise the steps:
A, high-frequency induction heating: 860～900 DEG C of high-frequency induction heating, be incubated 3 hours；
B, quenching: the gear after sensing heating is put in water and quenches, 1 hour time；
C, tempering: being put into by gear in tempering furnace and carry out temper, furnace temperature rises to 590-625 DEG C, be incubated 5 hours, come out of the stove
Air cooling is to room temperature.
The heating of this Technology for Heating Processing is more complete, makes the toughness of gear internal improve.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art is without wound
The property made work just can make many modifications and variations according to the design of the present invention.Therefore, all technical staff in the art depend on
The available technical scheme of logical analysis, reasoning, or a limited experiment is passed through in the design of the present invention on the basis of existing technology,
All should be in the protection domain being defined in the patent claims.
