Titanium clad steel plate and its application fields
Due to its excellent corrosion resistance, titanium is widely used as a material for various chemical reaction vessels and heat exchangers, and is widely used in petrochemical, salt production, electric power, seawater desalination, marine engineering and other fields. However, titanium has a disadvantage, that is, it is difficult to process, resulting in high costs. This problem is especially acute when used as structural components. At present, the effective solution that people come up with is to use titanium clad steel plate.
What is Titanium Plated Steel?
Titanium-steel clad plate refers to a metal clad plate coated with titanium with good corrosion resistance on the surface of ordinary steel plates. It not only has the strength of ordinary steel plate as a structure, but also has the corrosion resistance of titanium metal. The most important thing is that the cost is greatly reduced, so it is widely used in various fields.
At present, the manufacturing methods of titanium clad steel plates mainly include explosive cladding method, thick plate rolling method and continuous hot rolling method. Titanium clad steel plates manufactured by explosion cladding method and thick plate rolling method belong to thick plates and are mainly used as corrosion-resistant building materials. The titanium clad steel plate produced by continuous hot rolling is a thin plate, and the main application field is marine civil engineering.
Application fields of titanium clad steel plate
1. Manufacturing of petrochemical and chemical container equipment
Petrochemical and chemical container equipment manufacturing 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 plays an irreplaceable role in refineries and chemical plants.
Titanium also has special corrosion resistance to bleaching agents such as chlorine dioxide, chlorous acid, and chlorite. Therefore, titanium composite steel plates also have important applications in bleaching equipment in the textile printing and dyeing industry and paper industry.
2. Manufacturing of vacuum salt making equipment
Titanium and its alloys have excellent resistance to seawater, chloride solution corrosion and fluid corrosion. The evaporation chamber made of titanium-clad steel plate has a good effect on slowing down the corrosion of the evaporation tank wall, preventing salt scale scaling, prolonging the production cycle, improving the quality of salt products, and greatly reducing the use cost of salt plant 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, making titanium clad steel an ideal material for seawater desalination equipment.
4. Manufacturing of nuclear power equipment
Thick cladding (multi-layer ≥ 8mm), large plate width (single sheet area ≥ 20m) titanium clad steel sheet is the main material of the condenser tube plate of nuclear power equipment, the demand is large, and the application prospect is very broad.
In summary, titanium clad steel plate has excellent corrosion resistance and strength, and is an ideal material for manufacturing equipment in a corrosion-resistant environment. With the continuous improvement of the production process of titanium clad steel plate, its application will be more extensive and common.
