Abstract
The invention discloses a heat treatment technique of a reducer seat forging, which comprises the following steps: 1) putting a reducer seat forging in a quenching furnace, heating to 895 DEG C, keeping the temperature for 5 hours, and discharging; 2) putting the discharged reducer seat forging in a 75 DEG C oil-base quenching medium, and sufficiently cooling; and 3) putting the quenched drill pipe sub in a tempering furnace, heating to 695 DEG C, keeping the temperature for 7 hours, discharging, and naturally cooling to room temperature. The technique can enhance the strength, hardness, elongation percentage and ballistic work of the reducer seat forging, thereby enhancing the qualification rate of the reducer seat forging.
Description
Technical field
The present invention relates to the thermal treatment process of reducer pedestal forging.
Background technology
The intensity of existing reducer pedestal forging, hardness, unit elongation, ballistic work have much room for improvement.
Summary of the invention
The object of the present invention is to provide a kind of thermal treatment process of reducer pedestal forging, improve intensity, hardness, unit elongation, the ballistic work of reducer pedestal forging, thus improve the qualification rate of reducer pedestal forging.
For achieving the above object, technical scheme of the present invention designs a kind of thermal treatment process of reducer pedestal forging, comprises the steps:
1) reducer pedestal forging is placed in quenching furnance, is warming up to 895 DEG C, be incubated and come out of the stove after 5 hours;
2) the reducer pedestal forging of coming out of the stove is put into the oil base quenchant of 75 DEG C, fully cool;
3) drill pipe sub after quenching is placed in tempering stove, is warming up to 695 DEG C, is incubated and comes out of the stove after 7 hours, naturally cool to room temperature.
Advantage of the present invention and beneficial effect are: the thermal treatment process providing a kind of reducer pedestal forging, improve intensity, hardness, unit elongation, the ballistic work of reducer pedestal forging, thus improve the qualification rate of reducer pedestal forging.
Embodiment
Below in conjunction with embodiment, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
The technical scheme that the present invention specifically implements is:
A thermal treatment process for reducer pedestal forging, comprises the steps:
1) reducer pedestal forging is placed in quenching furnance, is warming up to 895 DEG C, be incubated and come out of the stove after 5 hours;
2) the reducer pedestal forging of coming out of the stove is put into the oil base quenchant of 75 DEG C, fully cool;
3) drill pipe sub after quenching is placed in tempering stove, is warming up to 695 DEG C, is incubated and comes out of the stove after 7 hours, naturally cool to room temperature.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
