Problems solved by technology

The explosive cladding method is usually carried out at room temperature, and refers to the method of using the impact force generated by the explosion of explosives to cause the workpieces to collide rapidly to achieve welding. The substrate of the composite board has a large deformation and is only suitable for the composite of thick metal plates.
The explosion-rolling composite method has disadvantages such as complex procedures, many factors affecting the bonding strength of composite plates, high energy consumption, long production cycle and high production cost. These series of problems greatly limit the use of this method.
In addition, the above two methods also have adverse effects such as high noise and environmental pollution, which are not conducive to environmental protection. Therefore, a working environment far away from the crowd is often required. As a result, some enterprises can only choose relatively remote locations for production, and their transportation costs etc. will also increase

Embodiment Construction

[0030] A method for preparing a zirconium-steel composite plate, the specific steps are as follows:

[0031] (1) Select a carbon steel plate 1 with a thickness of 100 mm and a carbon content of less than 0.2% and a zirconium plate 2 with a thickness of 10 mm, cut the steel plate 1 to a length and width of 2190 mm × 1190 mm, and cut the zirconium plate 2 to a size of 2100 mm × 1100 mm, using The thousand impeller uses an automatic grinding machine to process the surface to be bonded of the zirconium plate 2 and the surface to be bonded of the steel plate 1, so that the surface to be bonded has no oxide layer, impurities and voids, and the surface of the plate shows the true color of metal;

[0032] (2) To prepare release agent 5, take aluminum oxide powder and polyvinyl chloride powder with a mesh size greater than 200 and mix them with water according to the ratio of (2-3): (1-2): 100 and stir evenly, and evenly smear on the zirconium The non-bonded surface of board 2, with a ...

Abstract

The invention discloses a zirconium steel composite board, and a preparation method thereof. The zirconium steel composite board comprises carbon steel layers, a diffusion layer, and zirconium layers;the diffusion layer comprises carbon steel diffusion layers in the zirconium layers, and zirconium diffusion layers in the carbon steel layers. According to the preparation method, calendering combination after soldering and sealing is adopted, production can be carried out at a common working environment, problems of explosive cladding processing such as remote environment is needed, time is long, labor is consumed, and danger degree is high are solved.

Description

technical field [0001] The invention relates to a composite material and a manufacturing method of the composite material, in particular to a zirconium-steel composite plate and a preparation method thereof. Background technique [0002] Zirconium-steel composite plate is a new type of bimetal composite material with zirconium as cladding and steel as the base layer. It not only has the excellent corrosion resistance of zirconium, but also has the strength of carbon steel plate as a structure. [0003] At present, the manufacturing methods of zirconium steel clad plate mainly include explosive cladding method and explosive billet-rolling method. The explosive cladding method is usually carried out at room temperature, and refers to the method of using the impact force generated by the explosion of explosives to cause the workpieces to collide rapidly to achieve welding. The composite board substrate has a large deformation and is only suitable for the composite of thick met...
