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

Step 2., brake flange is put into cementing furnace carburizing, treatment temp is 900 DEG C, and the treatment time is 2 hours;
Step 3., carburizing quench under pressure is 0.3MPa after completing, to be cooled make its naturally cooling to when 50 DEG C;
Step 4., the heat treatment solution being heated to 40 DEG C in advance is sprayed into the surface of brake flange, heat treatment solution is made up of 20 parts of polyvinyl acetate emulsions, 15 parts of sodium polyphosphates, 1.5 parts of salt of wormwood, 0.5 part of anthra-glucoside, 10 parts of ethylene glycol and 55 parts of water;
Step 5., put into dry 5 hours of constant temperature oven to form protective membrane on its surface, constant temperature in-furnace temperature is 100 DEG C.
Preferably, the preparation method of the heat treatment solution that 4. described step uses is: first add 15 parts of sodium polyphosphates and 20 parts of water in container, stirs 10 minutes; Then 1.5 parts of salt of wormwood are slowly added, stirring while adding, stir 5 minutes after interpolation; Then 20 parts of polyvinyl acetate emulsions and 10 parts of water are slowly added, stirring while adding, stir 5 minutes after interpolation; Then 0.5 part of anthra-glucoside is slowly added, stirring while adding, stir 5 minutes after interpolation; Finally slowly add 10 parts of ethylene glycol and 25 parts of water, stir 20 minutes.
The useful effect of the present invention shows:
1) formulating of recipe of the heat treatment solution, used in thermal treatment process is novel, rationally, particularly with the addition of a small amount of anthra-glucoside, it is possible to significantly improve heat treated processing efficiency, form excellent protective membrane, the quality of product is significantly improved.
2), the preparation method of heat treatment solution, by progressively adding and choose reasonable order of addition(of ingredients), it is not only possible to improve the solubility property between each material, moreover it is possible to avoid the possibility of particle agglomeration, the thermal treatment protection function of heat treatment solution is promoted significantly.
3), automobile brake disc thermal treatment process; operating procedure is succinct; by spraying the step of heat treatment solution after increase carburizing; and the formula of appropriate design heat treatment solution and preparation method; form excellent protective membrane; thus realize thoroughly being protected of brake flange surface, then improve the thermal effectiveness of brake flange and the quality of product.
