Embodiment Construction

[0048] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0049] like figure 1 Shown, the present invention is used for the comparative analysis method of the quenching liquid of 410 round bar workpieces. First of all, in order to avoid waste and reduce economic losses, the staff used ultrasonic flaw detection to detect 2 scrapped 410 round bar workpieces and numbered them 1# and 2# accordingly, and used different quenching fluids for the intact parts of 410 round bar workpieces. Quenching and cooling treatment, and the 410 round bar workpiece after quenching and cooling treatment is reserved for testing. Secondly, choose the electro-hydraulic servo universal testing machine to longitudinally stretch the 410 round ...

Abstract

The invention relates to a contrastive analysis method for quenching liquid for 410 round bar workpieces. The contrastive analysis method comprises steps of 1, workpiece selection, 2, mechanical property detection, 3, impact property detection, 4, macroscopic morphology comparison, 5, metallographic detection and comparison and 6, summary analysis. According to the contrastive analysis method for the quenching liquid for the 410 round rod workpiece, the quenching liquid with the best quenching cooling effect on the 410 round rod workpiece is selected for use, the quality of the 410 round rod workpiece is improved, internal defects are reduced, the 410 round rod workpiece reaches various quality indexes, and use requirements are better met.

Description

technical field [0001] The invention relates to a method for comparative analysis of quenching liquid used for 410 round bar workpieces, and belongs to the technical field of heat treatment. Background technique [0002] Quenching liquid is the medium used for cooling in the steel quenching process. In addition to the quenching liquid, common media include water, air, etc., which can be used for quenching and cooling as the cooling medium. However, after analyzing its formula, in addition to professional quenching liquid, when cooling with special media such as water, it is easy to break due to the internal stress of the steel itself, thus affecting product quality. [0003] In order to ensure the quenching and cooling effect of a 410 round bar workpiece, to avoid the loss of performance of the 410 round bar workpiece due to the quenching and cooling of the quenching liquid, in order to make the 410 round bar workpiece after quenching and cooling have good mechanical proper...
