Problems solved by technology

This method will produce explosion noise, strong impact and smoke pollution, and it is not allowed to be produced around mature areas. In addition, the purchase and use of explosives must also apply for a license, and the management is very strict.

Embodiment 1

[0024] A 10mm thick stainless steel plate is combined with a 30mm thick Q235 steel plate. Firstly, one surface of the two metal materials is respectively processed by a milling machine to obtain a flat and smooth surface, and the degree of work hardening is about 100%.

[0025] After cleaning the two processed surfaces, press the hardened surfaces of the two materials against each other and closely overlap them, and press them on the press with a unit pressure of 0.3 ~ 2Mpa or press them at a pressure of 0.5Pa ~ 1X10 -2 Weld and seal the peripheral joints under the vacuum state of pa; heat the material, gradually heating to above 650°C, keep it warm for about 1 hour, then cool slowly, and the two materials are combined into one. The same method can be used to obtain a double-sided composite material in which the middle layer is plain carbon steel and the upper and lower layers are stainless steel.

Embodiment 2

[0027] Composite two 200mm thickness Q235 continuous casting billets. Firstly, one surface of the two steel billets is machined with a milling machine to obtain a flat and clean surface, and the degree of work hardening is about 100%.

[0028] After purging and cleaning the two processing surfaces, press the two material processing hardening surfaces relatively close together, and press them with a unit pressure of 0.3 ~ 2Mpa or 0.5Pa ~ 1X10 -2 Welding and sealing the peripheral joints under the vacuum state of Pa;

[0029] The material is heated, gradually heated to above 650°C, kept warm for about 2 hours, then cooled slowly, and the opposite surfaces of the two materials are combined into one. It is used as an extra-thick slab material for hot-rolled steel plates. It can also be heated at 650°C after the two materials have been compounded into one, and continue to be heated to the temperature required for rolling, and are directly used for rolling to produce steel plates....

Abstract

The invention discloses a cold deformation recrystallization course-based process method for producing a metal composite material, which aims to compound two or more metal materials with different material qualities or the same material quality. The process method comprises the main steps of: firstly, removing surface layers of the two metal materials by utilizing a mechanical processing method, mainly forming the cold hardening on processing surfaces to ensure that the surfaces are flat and clean; then, ensuring that the processing surfaces of the metal materials face towards each other and are aligned and superposed and completely adhered, and welding the peripheries of joint surfaces of the two metal materials under the condition of pressure compaction and / or vacuum; and gradually heating the welded combining block until the restoring and recrystallization temperature of the material T is more than 0.4T so as to ensure that the tissues of the two metal materials are integrated intoa whole. The invention can be used for compounding a stainless steel plate and a straight carbon steel plate, compounding the metals of nickel and titanium and the straight carbon steel plate, and compounding multilayer thin materials of the same material into thick materials.

Description

technical field [0001] The invention relates to a method for changing physical properties and causing metal compounding by performing heat treatment after deformation and hardening by cold work, and in particular relates to a process method for compounding two or more metal materials of different materials or multiple materials of the same material. Background technique [0002] The method of tightly compounding the same or two different metal materials is generally the process of welding bonding, explosive bonding or rolling bonding. The welding composite method can only weld the peripheral butt joints of the metal materials together, and cannot realize the large-area combination between the metal material plates. Although explosive recombination is not limited by edge recombination, the recombination process often requires the use of a large amount of explosives to generate power through explosion. This method will produce explosion noise, strong impact and smoke pollutio...
