Part treatment process

Abstract

The present invention discloses a part treatment process, which is characterized by specifically comprising: (1) normalizing; (2) annealing, wherein the annealing comprises re-crystallization annealing, destressing annealing, spheroidization annealing, and complete annealing; (3) tempering, wherein the tempering comprises low temperature tempering, medium temperature tempering, high temperature tempering, and multiple tempering; (4) quenching, wherein the quenching comprises salt bath quenching, martensite grading quenching, bainite isothermal quenching, surface quenching, and local quenching; and (5) quenching and high temperature tempering, wherein a quenching and tempering composite heat treatment process is performed. The part treatment process of the present invention has the following beneficial conditions that: the performance of the treated part is good, high hardness, high plasticity, high toughness and high wear resistance are provided, the structure defects are eliminated, and the part can work in a larger dynamic load.

Description

technical field [0001] The invention relates to a part processing technology. Background technique [0002] After the metal is cast, smelted and solidified into parts, the material of the parts needs to be further processed to make the parts have high hardness and relatively strong wear resistance. Many manufacturers will use normalizing, annealing, tempering or quenching heat treatment processes Parts are processed. However, the current processing of parts is only to change a single performance such as hardness or wear resistance. The overall performance of the part is not comprehensive. During use, the service life is short and easy to be damaged due to the lack of performance. Contents of the invention [0003] In order to solve the problems of incomplete processing and poor performance of the above-mentioned parts, the purpose of the present invention is to provide a part with good processing performance, high hardness, high plasticity and toughness, high wear resistan...
