Embodiment Construction

[0016] A kind of 2Cr13 heat treatment method is characterized in that: it is characterized in that comprising several steps:

[0017] (1) Slowly heat 2Cr13 to 30-50°C, keep it at 20°C for 30 minutes, and then cool down slowly.

[0018] (2) Forging and pressing of 2Cr13 material;

[0019] (3) Quenching and tempering treatment of 2Cr13 material; keep it at 1000 degrees for 9 hours, and cool it to 20 degrees when it comes out of the furnace;

[0020] (4) Pre-cooling and quenching of 2Cr13 material; cooling in the air for 10 minutes first, and then immersing in the cooling medium when the workpiece 2Cr13 drops to 25 degrees.

[0021] The cooling medium in step (3) is water, ice-water mixture.

[0022] Carry out cold treatment before step (2), and continue cooling to 10 degrees.

[0023] Step (4) is followed by spheroidizing annealing, the temperature is kept between 500 and 575°C, and the annealing time is 8 to 12 hours.

[0024] Step (4) is followed by graphitization treatmen...

Abstract

The invention discloses a 2Cr13 heat treatment method, belonging to technical field of heat treatment. The method has the advantages of energy saving and emission reduction, and can not generate harmful gas for air. Due to the technical scheme, the method is convenient for production, very low in cost and suitable for wide popularization.

Description

technical field [0001] The invention relates to a 2Cr13 heat treatment method, belonging to the technical field of heat treatment. Background technique [0002] With the development of industrial modernization, the heat treatment process is accompanied by high energy consumption and high pollution. Human beings have changed the composition of the air in some areas during their life and production activities. The main pollutants that cause air pollution are the discharge of harmful substances such as carbon dioxide and sulfur dioxide. [0003] At present, toxic gas is also emitted during the heat treatment process of 2Cr13. Contents of the invention [0004] The present invention aims at the proposal of above problem, and develops a kind of 2Cr13 heat treatment method. [0005] A kind of 2Cr13 heat treatment method, it is characterized in that: comprise several several steps: [0006] (1) Slowly heat 2Cr13 to 30-50°C, keep it at 20°C for 30 minutes, and then cool down sl...
