3.Application case锛?/strong>
1) ship building
Copper alloy clad plate can provide a cheaper, stronger anti-corrosion and biological pollution of the outer surface. The cost of Copper alloy clad steel plate is lower than that of solid Cu-Ni plate with the same thickness. The Copper alloy clad steel plate can be made of hot rolled steel and copper alloy composite or explosive welding.
2) Vacuum salt making
Material:BF30-1-1 copper plate clad ASTM A36(Q235B) steel plate
Vacuum salt making is a kind of modern salt making method that brine is evaporated in different "vacuum" evaporation tank groups. Due to the pressure drop difference between the tanks, the boiling point is gradually reduced, so that the heat is transferred in turn, and the "secondary steam" can be used for many times. This method has the advantages of high mechanization and automation, low heat consumption and low production cost.
3)Electrolytic copper foil
Material:copper T2 plate clad Q235B steel plate
In the production of electrolytic copper foil, the cathode roller is an inner roller (conductive) made of composite plate of copper T2 plate clad Q235B steel plate
4) Conductive cross arm of box type heating furnace
Material: copper T2 plate clad Q235B plate
copper T2 plate clad Q235B plate has been widely used in the conductive cross arm of box heating furnace.

5.FAQ
1) What are the methods of producing clad plate?
Pouring method, forging method, powder metallurgy method, powder metallurgy rolling method, welding method (diffusion welding, surfacing), rolling bonding method, explosive welding, explosive welding plus rolling method and so on. Based on metal properties, product specifications, service conditions of clad plate, market demand, technological progress and equipment update, rolling clad method, explosive welding and explosive welding rolling method are the main production methods at present.
2) Principle of rolling clad method?
There are two kinds of rolling compound method, cold rolling and hot rolling. The basic principle is: under the strong pressing action of rolling mill, or the combination of preheating action, plastic deformation occurs on the cross section of two metal materials to be compound, resulting in plastic deformation or fracture of the surface to be compound, and then clean, activate, and continue to form a planar metallurgical bonding form under the action of strong stress. It is different from single metal rolling in that a strong pass reduction must be applied, especially the initial pass. Only under this condition can the physical contact between the two metal materials to be compounded be made as full as possible.
3) Principle of explosive welding?
Metal explosive welding is a metal processing technology that uses explosives as energy to weld two or more metal materials into one. Large area metal explosive welding is called metal explosive composite. It is different from other metal clad plate production methods. In a very short time, it is in the order of microseconds, the workpiece is applied with high-voltage pulse load (about 1000000 ATM), the loading stress is far higher than the dynamic yield strength of the metal material; the loading process is instantaneous, within a few microseconds; the workpiece only bears the load locally, and it is in a state of high-speed movement, and the deformation only occurs in the action zone The bonding zone is a wavy metallurgical bonding form.
4) Principle of explosive welding plus rolling?
Based on the advantages of the above two production methods, the thick composite slab is made by explosive welding, and then the required thickness, width and length of composite slab are made by hot rolling or cold rolling according to different conditions or requirements. This is not only a production method, but also a technological progress, and also promotes the improvement of equipment manufacturing, which greatly improves the quality, reliability and service life of the equipment.China Copper Clad Plate
