Thermal treatment process for automobile brake disc

Abstract

The invention relates to the technical field of automobile part processing, in particular to a thermal treatment process for an automobile brake disc. The thermal treatment process comprises the following steps: wiping greasy dirt on the surface of the brake disc and scrubbing the brake disc by use of alcohol; putting the brake disc into a carburizing furnace for carburizing, quenching the brake disc after carburizing is completed, and then, naturally cooling the brake disc; spraying a thermal treatment solution which is preheated to a temperature of 40 DEG C to the surface of the brake disc, wherein the thermal treatment solution is prepared from 20 parts of vinyl acetate emulsion, 15 parts of sodium polyphosphate, 1.5 parts of potassium carbonate, 0.5 part of anthraquinone glycoside, 10 parts of ethylene glycol and 55 parts of water; and putting the brake disc into a constant-temperature furnace to dry for 5 hours, thereby forming a protective film on the surface of the constant-temperature furnace, wherein the temperature in the constant-temperature furnace is 100 DEG C. According to the thermal treatment process for the automobile brake disc, the operation process is simple, and the excellent protective film is formed by increasing the process of spraying the thermal treatment solution after carburizing, reasonably designing the formula and the preparation method of the thermal treatment solution, so that the surface of the brake disc is completely protected, and therefore, the thermal treatment effect of the brake disc and the product quality are improved.

Description

technical field [0001] The invention relates to the technical field of processing parts for automobiles, in particular to a heat treatment process for an automobile brake disc. Background technique [0002] In the prior art, heat treatment is an indispensable processing procedure when the brake disc is processed. In the prior art, after the carburizing step of the brake disc during heat treatment, no heat treatment liquid is added as a reinforcing agent, which will result in low heat treatment efficiency, low product quality, damage to the product surface, and other defects, which are prone to rework . Contents of the invention [0003] In view of the technical problems existing in the prior art, the purpose of the present invention is to provide a heat treatment process for automobile brake discs. In order to achieve the above purpose, the present invention adopts the following technical solutions: [0004] A heat treatment process for an automobile brake disc, the step...
