Embodiment 1

[0052] Carry out billet assembly as follows:

[0053] ①Process two steel plates and two titanium plates with dimensions of 200×160×18mm and 160×120×20mm respectively, two side plates of 120×20×40mm and 200×20×40mm respectively, and grind and polish the surface , to remove surface dirt and oxide layer;

[0054] ② Make a hole on one of the side plates, and weld a seamless carbon steel pipe with a wall thickness > 2mm at the hole;

[0055] ③ Then carry out symmetrical billet assembly in the order of steel plate / titanium plate / titanium plate / steel plate, coat the release agent on the adjacent surfaces of the two titanium plates, and set the side plate around the titanium plate and between the two steel plates , the gap between the steel plate and the side plate and the gap between the side plate and the side plate are welded by argon arc welding, so that all materials become a combination;

[0056] ④ After the welding is completed, connect the seamless carbon steel pipe to the vac...

Embodiment 2

[0059] Roll the titanium-steel clad plate as follows:

[0060] ①Put the combined billet prepared in Example 1 into a heating furnace and heat to 950°C, and keep it warm for 360min;

[0061] ② Take out the combined billet that has completed the heating process, and carry out rolling. The first pass is deformed by 10%, after 12 passes of rolling, the cumulative deformation is 88%, the rolling speed is 0.2m / s, and the final rolling temperature is 660°C;

[0062] ③ After the rolling is completed, the edge of the rolled plate is cut off, and the two titanium plates are naturally separated due to the action of the release agent, so that two titanium-steel composite plates can be obtained.

[0063] The obtained titanium-steel clad plate was tested for bonding strength, and the interface bonding strength was obtained to be 250MPa. Wherein, the bonding strength determination method is carried out according to the shear test method in GB / T 6396-2008.

Embodiment 3

[0065] Roll the titanium-steel clad plate as follows:

[0066] ①Put the combined billet prepared in Example 1 into a heating furnace and heat it to 780°C, and keep it warm for 360min;

[0067] ② Take out the combined billet that has completed the heating process, and carry out rolling. The first pass is deformed by 5%, after 12 passes of rolling, the cumulative deformation is 72%, the rolling speed is 0.1m / s, and the final rolling temperature is 600°C;

[0068] ③ After the rolling is completed, the edge of the rolled plate is cut off, and the two titanium plates are naturally separated due to the action of the release agent, so that two titanium-steel composite plates can be obtained.

[0069] The obtained titanium-steel clad plate was tested for bonding strength, and the interface bonding strength was obtained to be 190-200 MPa. Since the heating temperature and the amount of deformation are close to the lower limit, the bonding strength is low and fluctuates. Among them, t...

Abstract

The invention relates to a material assembling method and rolling method for a titanium-steel clad plate and belongs to the field of titanium-steel clad plate manufacturing and processing. The material assembling method comprises the following steps: a, preparing two steel plates, two titanium plates and four side plates and removing an oxidation layer and oil stains on the surface of each plate; b, forming a hole in at least one side plate and welding a seamless carbon steel pipe at each opening hole; c, symmetrically assembling a blank from one steel plate, the two titanium plates and the other steel plate in sequence, and welding the blank into a combination body; d, after welding, connecting each seamless carbon steel pipe with a vacuum pump, vacuumizing to reach a pressure value no greater than 1*10<-2>Pa and sealing the seamless carbon steel pipe to obtain an assembled blank material. According to the material assembling method of the titanium-steel clad plate, the internal vacuum treatment of the blank material can be completed without the help of a vacuum electron beam welding box, and thus the production procedure is simplified, the cost is saved, the assembling effect is good and the problem of the interface oxidation of the titanium-steel clad plate can be effectively solved.

Description

technical field [0001] The invention relates to a material assembly method and a rolling method of a titanium-steel composite plate, and belongs to the field of preparation and processing of a titanium-steel composite plate. Background technique [0002] Titanium has good physical, chemical and mechanical properties, but its smelting technology is complicated and the production cost is high, so the price of titanium is very expensive, which greatly limits the promotion and application of titanium. Combining titanium with other metals (such as steel, copper, aluminum, etc.) -Steel composite materials are widely used in chemical, petroleum and other industrial sectors because of their high strength, excellent corrosion resistance and significant economic benefits. [0003] At present, there are four main production methods of titanium-steel clad plates: explosive clad method, diffusion clad method, explosion-rolling and direct rolling method. The direct rolling method is the...
