Manufacturing Methods and Applications of Titanium Clad Steel Plates
In modern industrial materials, titanium clad steel plates have gradually become a hot spot in materials science research due to their unique properties and wide range of applications. This article will provide a detailed explanation of the manufacturing methods of titanium clad steel plates and explore their applications in different fields.
What Is A Titanium-clad Steel Plate?
The titanium-steel clad plate refers to a metal-clad plate coated with titanium with good corrosion resistance on the surface of the ordinary steel plate. It not only has the strength of an ordinary steel plate as a structure but also has the corrosion resistance of titanium metal. The most important thing is that the cost has been greatly reduced, so it is widely used in various fields.
At present, there are three main manufacturing methods for titanium-clad steel plates, namely, the explosive-clad method, the thick plate rolling method, and the continuous hot-rolling method. The titanium-clad steel plates manufactured by the explosive-clad method and thick plate rolling method are thick plates and are mainly used as corrosion-resistant construction materials. The titanium-clad steel plates manufactured by continuous hot rolling are thin plates, and the main application field is marine civil engineering.
Explosive Welding Method
First, a certain distance is maintained between the two metal plates, and then an appropriate amount of explosives is placed on top. The explosive is detonated from one end with a speed of thousands of meters per second, causing the titanium plate to collide with the substrate steel plate at an angle. At the collision point, the substrate steel plate and the titanium plate exhibit fluid behavior due to the extremely high deformation speed and ultra-high pressure. The oxide films and gas adsorption layers on the surfaces of the two metals are expelled as metal jets, and the clean surfaces bond instantly.
Thick Plate Rolling Method
The thick plate rolling method initially assembles the titanium plate (composite material) and the steel plate (substrate) into an embedded slab. At this time, a suitable intermediate embedding material is placed between the titanium plate and the steel, and then electron beam welding is used in a high vacuum. Finally, after heating in a heating furnace, the assembly is strongly rolled to the desired thickness on a thick plate rolling mill, effectively bonding the titanium plate and the steel plate. The periphery is then cut, separating it into 2 plates.
Continuous Hot Rolling Method
The continuous hot rolling method is basically the same as the thick plate rolling method, except that a steel plate is added between the two plates. Arc welding is conducted under atmospheric conditions, and finally, continuous rolling is performed on a continuous hot rolling mill to the required thickness, with the result taken out in coil form. The periphery is then cut, separating it into 2 plates.
Application Fields
1. Petrochemical and Chemical Container Equipment Manufacturing
The manufacturing of petrochemical and chemical container equipment is the traditional application field of titanium-clad steel plate materials, and its consumption has always been the first. Titanium has good stability in various acid, alkali, and salt media in the chemical industry. Therefore, titanium-clad steel plates play an irreplaceable role in petroleum refineries and chemical plants.
Titanium also has special corrosion resistance to bleaching agents such as chlorine dioxide, chlorous acid, and chlorite. Thus, titanium-clad steel panels also have important applications in bleaching equipment in the textile printing and dyeing industry and papermaking industry.
2. Vacuum Salt-Making Equipment Manufacturing
Titanium and its alloys have excellent resistance to seawater, chloride solution corrosion, and fluid erosion resistance. The evaporation chamber made of titanium-clad steel plates has good effects on slowing down corrosion and preventing salt scaling on the evaporation tank wall, prolonging the production cycle, and improving the salt quality, which greatly reduces the use cost of salt factory equipment.
3. Desalination Field
Titanium and titanium alloys have excellent resistance to seawater, chloride solution corrosion, and fluid erosion, and titanium is non-toxic and harmless, which makes titanium-clad steel plates an ideal material for seawater desalination equipment.
4. Nuclear Power Equipment Manufacturing
Thick cladding (multilayer ≥ 8mm), large plate width (single sheet area ≥ 20m) titanium-clad steel plate is the main material for condenser tube sheets in nuclear power equipment, and the demand is very large, and the application prospect is very broad.
In summary, titanium clad steel sheets have become an indispensable part of modern industrial materials due to their unique manufacturing methods and wide range of applications. With ongoing technological advancements and expanded applications, titanium clad steel plates will demonstrate their unique value in more fields.
