Problems solved by technology

It is difficult to meet such requirements in actual production, because the shape and thickness of forgings are different, and the heating and cooling speeds are inconsistent, resulting in inconsistent mechanical properties and hardness values ​​of various parts of forgings.

Embodiment Construction

[0017] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:

[0018] As shown in the figure, a heat treatment method for special-shaped forgings includes the following steps:

[0019] S1: After the special-shaped forgings are released from the furnace, they are placed on the transfer device at equal intervals, and the transfer device transports the special-shaped forgings to the first station for heating;

[0020] S2: After the special-shaped forging is heated, it is transported to the second station by the transfer device, quenched in the low-temperature bath salt, and stays in this stage for 2min-5min;

[0021] S3: The special-shaped forging is transported to the third station by the transfer device, and is naturally cooled at the third station;

[0022] S4: The special-shaped forging is transported to the fourth station by the transfer device, and is cleaned and air-dried;

[0023] S5: The special-shaped forging i...

Abstract

The invention relates to a heat treatment method of special-shaped forgings, which comprises the following steps: S1: after discharging the special-shaped forgings, putting the special-shaped forgings on a conveyer at equal intervals, conveying the special-shaped forgings to a first station by the conveyer, and heating; S2: after heating the special-shaped forgings, conveying to a second station by the conveyer, and quenching in a cold bath salt for 2-5 minutes; S3: conveying the special-shaped forgings to a third station by the conveyer, and naturally cooling in the third station; S4: conveying the special-shaped forgings to a fourth station by the conveyer, cleaning and airing; and S5: conveying the special-shaped forgings to a fifth station by the conveyer, and carrying out tempering. All the stations are connected together by the conveyer, so that the special-shaped forgings can be conveyed to the corresponding positions at one time, thereby avoiding scalds and other hurts caused by manual operation.

Description

technical field [0001] The invention relates to a heat treatment, in particular to a heat treatment method for a special-shaped forging. Background technique [0002] In terms of heat treatment process: After heat treatment, the mechanical properties of forgings should be stable, and the hardness value of each part should be uniform and uniform. It is difficult to meet such requirements in actual production, because the shape and thickness of forgings are different, and the heating and cooling speeds are inconsistent, resulting in inconsistent mechanical properties and hardness values ​​of various parts of forgings. Therefore, in the process of heat treatment, the quality and performance have been fluctuating greatly, and each batch is different, which requires us to further improve and guarantee the heat treatment quality of this product. Contents of the invention [0003] In order to overcome the deficiencies in the technical background, the invention provides a heat tr...
