Titanium aluminum steel clad plate

Titanium plate has been brought into full play under many corrosion conditions because of its excellent corrosion resistance. Aluminum has become the most cost-effective conductive material because of its low specific gravity and excellent conductivity. Titanium aluminum steel clad plate is formed by using titanium as corrosion-resistant metal, aluminum as conductive metal and steel as load-bearing metal。

The application of titanium aluminum steel clad plate in sodium chloride electrolyzer fully shows the superior characteristics of each group of metals (resistance to chloride ion corrosion, conductivity of aluminum layer and pressure bearing of steel plate). It not only prolongs the service life and maintenance cycle of the equipment, but also greatly reduces the manufacturing cost of the equipment.



The current titanium / aluminum / steel explosive welding process uses steel plate as the base, aluminum plate as the transition layer and titanium plate as the multi-layer. In the explosive welding process, due to the large amount of explosives, aluminum / steel is easy to be layered, the aluminum plate in the middle layer is seriously thinned, and the bonding performance of titanium / aluminum joint surface is poor. The titanium / aluminum / steel explosive composite plate with specification of 8 / 6 / 24 is used in the current process explosive composite sodium chloride electrolytic cell. The thickness of the transition layer aluminum plate is generally 12 ~ 14mm, so as to ensure the thickness of the transition layer of 6mm and the conductivity of the titanium / aluminum / steel composite plate. However, the aluminum plate has large thinning amount, difficult control and low yield.

Because of the realization of titanium / aluminum welding in the current process, according to the calculation of explosive welding window, the titanium plate forms an effective inclined collision angle, the explosion speed needs to reach 1900 ~ 2000m / s, and the charge amount needs to reach about 60mm. During explosive welding with this charge, the aluminum plate of the transition layer has large deformation, serious thinning, and delamination is easy to occur at the aluminum / steel interface. On the contrary, due to the low explosion speed and insufficient charge, the titanium plate can not form a bending angle and effective inclined collision, that is, the explosive welding of titanium / aluminum can not be realized.

The explosive composite structure of titanium aluminum steel clad plate comprises a steel substrate, a titanium plate and an aluminum plate, the steel substrate is placed on the foundation, the titanium plate is located above the steel substrate, the aluminum plate is located above the titanium plate, the steel substrate and the titanium plate, and the titanium plate and the aluminum plate are separated by support sheets, and the upper side of the aluminum plate is paved with an explosive layer, The explosive layer comprises a main explosive and a high-speed explosive strip, the explosion speed of the high-speed explosive strip is higher than that of the main explosive, the main explosive is evenly laid on the upper side of the aluminum plate, the high-speed explosive strip is continuously laid along the long side direction in the middle of the upper side of the aluminum plate, and the middle of the explosive layer is connected with a detonator. The problem to be solved is the low bonding strength between aluminum and steel, and the excessive use of titanium plate. Aluminum plate is used as corrosion resistant material. However, the corrosion resistance of aluminum is limited, and it is a bit extravagant to use precious titanium as the transition layer.

aluminum provides a method to solve the delamination of aluminum / steel interface in the explosion composite titanium layer of titanium / aluminum / steel in the current process. It is also a method to solve the serious thinning of aluminum in the middle layer in the explosion composite titanium / aluminum / steel in the current process, and to solve the non welding of titanium / aluminum interface in the explosion composite titanium layer of titanium / aluminum / steel in the current process, The preparation method of titanium aluminum steel clad plate can make titanium aluminum steel clad plate have the characteristics of good bonding rate, high bonding strength, taking into account the corrosion resistance of titanium material, good transition of aluminum plate and steel plate strength, and low cost. The titanium / aluminum / steel composite plate on the sodium chloride electrolytic cell has thick aluminum plate and titanium plate.
