1. Product description
Explosive welding, also known as explosive recombination, is a new technology that uses the energy generated at the moment of explosive explosion as energy to weld metal. Titanium clad steel tube sheet by explosive welding combines the advantages of each metal component to obtain physical and chemical properties that a single metal does not have, such as excellent corrosion resistance and high strength. Titanium steel clad tube sheet by explosive welding has been promoted and applied in machinery, aerospace, ships, construction, nuclear energy, petrochemical and other industrial fields. As the interface between titanium and medium in titanium/steel clad plate equipment, titanium can give full play to its corrosion resistance; Stainless steel has excellent mechanical properties. Titanium/stainless steel welding components can not only meet the needs of industry for titanium, but also play the common ground between the two, greatly reducing the fixed investment cost of chemical equipment.
2. Product Features
At present, in the domestic explosion compound production, the detonating method is to use the instantaneous electric detonator. In order to improve production efficiency, multiple composite plates are used to detonate at the same time. Explosive compounding has the hazard characteristics of open-air blasting. The harmful phenomena, such as explosion shock waves and blasting vibrations, increase with the increase of the quantity of primary explosives. Delayed blasting technology is an effective way to reduce harmful phenomena such as blasting shock wave and blasting vibration. If the delayed blasting technology is introduced into explosive compound production, the harmful phenomena caused by blasting can be effectively reduced on the premise of increasing the number of single compound and improving the production efficiency. When the delayed blasting technology is applied in explosive compounding, the time difference between blasting points will inevitably affect the quality of explosive compounding.
3. FAQ
The solid phase bonding of titanium/steel is the precondition for the appearance of the interfacial reaction phase. Solid phase bonding is achieved through different technologies
The method makes the surface of the two materials form an interface to produce metallurgical bonding. Its essence is: under the effect of pressure, the contact surface is close to the distance between atoms, and a large number of binding points are generated due to adsorption between atoms. The early research on the solid phase bonding mechanism mainly formed the following theories: recrystallization theory, energy theory, metal bond theory, diffusion theory, etc. Due to the limitations of early experimental methods, most of these theories focus on the change or a certain process after bimetallic bonding, and cannot accurately and completely reveal the essence of the solid phase bonding process. With the development of characterization methods such as scanning electron microscope and atomic force microscope, the real surface of metal micro is gradually recognized.
