What Is The Specific Method For Hot Rolling Production Of Titanium Steel Composite Plates?

1. One of the methods for the production of titanium steel clad plate is hot rolling, which requires the formation of an iron-based material and a titanium cladding material, and the coating has at least one cladding surface side plate assembly, and the coating material of the base material and 20 to 30 g/m2 Mo or V are required. It is heated at the temperature of the melting point, oxidized between 50 degrees Celsius and 1050 degrees Celsius to reduce titanium oxides, and then hot rolled.

2. The oxide that needs to be added is MoO3.

3. The heating temperature is between 845 degrees Celsius and 1050 degrees Celsius.

4. Oxide V2O5 needs to be added.

5. The heating temperature is between 740 degrees Celsius and 1050 degrees Celsius.

This technology is actually a process for producing titanium-steel composite plates through hot rolling, which has excellent cladding properties and is also very economical in production cost. In the production process of stainless steel composite plates, hot rolling processing is more popular and suitable for mass production. However, this is not suitable for the production of titanium-steel composite plates. This is because titanium is prone to reaction; at high temperatures, it can potentially undergo chemical reactions with air or other metals, so the properties of titanium require it to be clad during hot rolling. Achieving good cladding is difficult. Therefore, when producing titanium-steel composite plates through hot rolling, other materials need to be added between titanium and the base material to prevent the formation of compounds at the boundary between titanium and iron.

Another simple production method

Steel Plate Rolling and Air Cooling: The steel plates are rolled on hot rolling mill to 6 mm thick steel plates and air cooled4.

Surface cleaning and rolling: The surfaces of the steel and titanium plates are cleaned after air cooling, and then rolled at 850℃ for 2 - 5 passes4.

Chemical composition requirements: The chemical composition of the steel plate is C: 0.16%, Mn: 0.61%, Si: 0.2%, S: 0.23%, P: 0.019%, Cr: 0.3%, Ni: 0.3%, Cu: 0.3%, As: 0.08%, and the balance is Fe; the chemical composition of the titanium plate is Fe: 0.08%, O: 0.08%, C: 0.05%, N: 0.0112%, Si: 0.01%, H: 0.01%, and the balance is Ti4.
