Embodiment Construction

[0011] The present invention will be further described below in conjunction with the examples, but not as a basis for limiting the present invention.

[0012] Example. The anti-deformation heat treatment process for metal parts includes the following process steps:

[0013] (1) The metal parts are pickled in 15% hydrochloric acid solution, ultrasonically treated in the later stage of the treatment, and finally rinsed with pure water and dried;

[0014] (2) Metal parts are coated with a protective layer, and the components in the protective layer are proportioned according to the following parts by weight: 45 parts of glass frit, 2 parts of iron oxide, 5 parts of chromium oxide, 8 parts of copper oxide, 2 parts of aluminum oxide, acrylic acid 6 parts, 15 parts of polyvinyl acetate emulsion, 15 parts of ethanol solution;

[0015] (3) Heating by laser flame spraying, heating to a temperature of 860°C, and continuing heating for 12 minutes;

[0016] (4) Cooling the metal parts,...

Abstract

The invention discloses a heat treatment process for anti-deformation of metal parts, which comprises the following process steps: (1) pickling treatment of metal parts in 15% hydrochloric acid solution, ultrasonic treatment in the later stage of treatment, and finally washing with pure water, blowing Dry; (2) Metal parts are coated with a protective layer, and the components in the protective layer are proportioned according to the following parts by weight: 45 parts of glass frit, 2 parts of iron oxide, 5 parts of chromium oxide, 8 parts of copper oxide, and 2 parts of aluminum oxide , 6 parts of acrylic acid, 15 parts of polyvinyl acetate emulsion, 15 parts of ethanol solution; (3) Heating by laser flame spraying, heating to a temperature of 860 ° C, and continuing heating for 12 minutes; (4) Cooling metal parts, the temperature is cooled to 120 ° C , the cooling medium is a polyalkylene glycol polymer aqueous solution with a concentration of 14%. The invention can prevent the deformation of the metal parts and ensure the quality of the metal parts.

Description

technical field [0001] The invention relates to a heat treatment process, in particular to a casting anti-deformation heat treatment process. Background technique [0002] Metal heat treatment is a process that heats, heats and cools a metal workpiece in a certain medium, and controls its performance by changing the surface or internal structure of the metal material. Metal heat treatment is one of the important processes in mechanical manufacturing. Heat treatment generally does not change the shape and overall chemical composition of the workpiece, but changes the molecular structure inside the workpiece by heating, or changes the chemical composition of the surface of the workpiece, endows or improves the properties of the workpiece. Use performance. The current metal workpiece heat treatment process often has a large deformation of the metal workpiece due to the single process. Contents of the invention [0003] The purpose of the present invention is to provide a me...
