Embodiment Construction

[0031] The present invention provides a steel plate pre-hardening process and pre-hardened steel plate. In order to make the purpose, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] see figure 1 , the invention provides a steel plate pre-hardening process, the process comprises the following steps:

[0033] S1, select the base metal steel plate whose material is 65Mn;

[0034] S2, shelling the base metal steel plate; removing the scale on the surface of the base metal steel plate;

[0035] S3, drying the base metal steel plate after shelling;

[0036] S4, apply oil (such as alkane oil or silicone oil, etc.) on the surface of the base metal steel plate;

[0037] S...

Abstract

The invention discloses a steel plate pre-hardening process and a pre-hardened steel plate. The steel plate pre-hardening process comprises the steps of selecting a mother material steel plate, shelling, drying, oiling, slitting, heating to a curling temperature, carrying out vacuum heat preservation, cold pressing, first annealing, finishing, second annealing, cold hardening, tempering testing, fine adjusting. According to the steel plate pre-hardening process, the steel plate with the preset thickness and hardness is processed, the pre-hardened steel plate is used for making parts have certain hardness when being used for manufacturing the parts, no quenching is carried out in the part manufacturing process, machining steps and time are saved, and the production efficiency of parts is improved.

Description

technical field [0001] The invention relates to the technical field of steel plate production, in particular to a steel plate pre-hardening process and a pre-hardened steel plate. Background technique [0002] The hardness range required by some 65Mn steel parts in automobile manufacturing and other industries is not very high, but in actual production, it is necessary to quench the processed parts to obtain a certain hardness, but this will increase the production cycle of parts and reduce the production efficiency. Therefore it is necessary to propose a steel plate pre-hardening process and pre-hardened steel plate. The parts made of pre-hardened steel plate have a predetermined hardness, so it is no longer necessary to heat and quench it, which shortens the production cycle of parts and helps to improve production efficiency. [0003] It can be seen that the prior art still needs to be improved and enhanced. Contents of the invention [0004] In view of the deficienc...
