Problems solved by technology

[0005] The invention can solve the problem that the existing equipment has poor heating effect when the steel plate is quenched and heated, the temperature distribution on the surface of the steel plate is uneven, and the steel plate will generate relatively large thermal stress when it is cooled, which causes the steel plate after quenching to easily deformation, warping, etc., and when quenching and heating the steel plate, the installation effect of the flame nozzle is poor, and it is inconvenient to replace, and it is impossible to quickly adjust the spray size of the flame nozzle. The nozzle cannot fit the curved steel plate and other problems

Embodiment Construction

[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0036] Such as Figure 1 to Figure 5 Shown, a kind of metal material surface modification processing method comprises the following steps:

[0037] S1. Selection of steel plate: choose medium carbon steel plate or high carbon steel plate of appropriate size according to the needs of use;

[0038] S2, surface cleaning: manual cleaning and removal of impurities such as scale, burrs, and rust on the surface of the steel plate selected in step S1;

[0039] S3. Pretreatment: pretreat the steel plate by one or more methods of normalizing, annealing, quenching and tempering treatment and spheroidizing annealing, so as to meet the needs of mechanical processing and prepare for the final heat treatment;

[0040] S4, quenching treatment: put the steel plate...

Abstract

The invention relates to a metal material surface modified treatment method. According to the metal material surface modified treatment method, a bottom plate, a conveying rack and a quenching deviceare provided; the conveying rack is arranged at the upper end of the bottom plate; the quenching device is arranged above the conveying rack; and the lower end of the quenching device is arranged on the bottom plate. By the metal material surface modified treatment method, the phenomena that a quenched steel plate is liable to deform and warp due to that the heating effect is bad when existing equipment performs quenching heating on a steel plate, the temperature is distributed non-uniformly after the surface of the steel plate is heated as well as large heat stress is generated when the steelplate is cooled can be solved; furthermore, the problem that the jet size of a flame nozzle cannot be adjusted rapidly due to that the flame nozzle has bad mounting effect and is inconvenient to change when the steel plate is subjected to quenching heating can be solved; meanwhile, the problem that the flame nozzle cannot be matched with an arc-shaped steel plate because the angle of the flame nozzle is generally arranged fixed can be solved.

Description

technical field [0001] The invention relates to the technical field of metal material surface treatment, in particular to a metal material surface modification treatment method. Background technique [0002] The purpose of surface modification of steel plate is to improve the strength, hardness, wear resistance, fatigue strength and toughness of steel plate, so as to meet the different requirements of various mechanical parts and tools, and also meet the requirements of some special steel through surface modification. Special physical and chemical properties such as ferromagnetism and corrosion resistance. [0003] At present, the existing metal steel plates generally have the following defects when surface modification is carried out: 1. When the steel plate is quenched and heated, the heating effect is poor, the temperature distribution of the steel plate surface is uneven after being heated, and the steel plate will generate heat when it is cooled. The large thermal stre...
