Abstract
The invention relates to a thermal treatment process and mainly relates to high-abrasion-resistance gears. The thermal treatment process is characterized in that the process includes the following steps that A, carburizing and quenching are performed, specifically, a gear is carburized at the temperature of 900-955 DEG C; B, water quenching is performed, specifically, the carburized gear is cooled to 780-800 DEG C, kept warm for 2-2.5 hours, put in water for quenching and then cooled to room temperature; and C, tempering is conducted, specifically, the water-quenched gear is subjected to tempering at the temperature of 180-200 DEG C and kept warm for 2-2.5 hours. Accordingly, gear heating is more complete, and the interior tenacity of the gear is improved.
Description
Technical field
The present invention relates to a kind of Technology for Heating Processing, relate generally to.
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 Technology for Heating Processing,
It is more complete that this process makes it heat, and makes the toughness of gear internal improve.
For achieving the above object, the invention provides a kind of Technology for Heating Processing, it is characterised in that: comprise the following steps:
A, carburizing and quenching；
B, shrend；
C, tempering.
Further, in described step A, gear is carried out carburizing at 900-955 DEG C.
Further, in described step B, the gear after carburizing is cooled to 780～800 DEG C, is incubated 2-2.5 hour, puts
Enter after water quenches to room temperature.
Further, in described step C, the gear after shrend is tempered at 180～200 DEG C, is incubated 2-2.5 hour.
The invention has the beneficial effects as follows: the present invention makes gear heating more complete, makes the toughness of gear internal improve.
Detailed description of the invention
The Technology for Heating Processing that the present invention is a kind of, comprises the following steps: A, carburizing and quenching；
B, shrend；C, tempering.
Further, in described step A, gear is carried out carburizing at 900-955 DEG C.
Further, in described step B, the gear after carburizing is cooled to 780～800 DEG C, is incubated 2-2.5 hour, puts
Enter after water quenches to room temperature.
Further: in described step C, being tempered at 180～200 DEG C by the gear after shrend, 2-2.5 is little in insulation
Time.
The present invention makes gear heating 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.
