Manufacturing method of clad steel plate
Sep 27, 2018

Generally, the manufacturing method of the clad steel plate includes a filled metal ingot rolling method, an explosive cladding method, a rolling pressure bonding method, a build-up welding method etc. 

Considering the characteristics of titanium, the industry often uses explosive cladding method or rolling and crimping method, and the actual production method includes: Explosion cladding method. The rolling and crimping method includes and Thick plate rolling method3. Continuous hot rolling method. The explosive cladding method is usually carried out at a normal temperature, and the rolling and crimping method is to assemble a plate and heat and roll it.

Explosive cladding 

The main points of the explosive cladding method: firstly, the two metal plates to be crimped are placed at a certain interval, and an appropriate amount of explosive is placed thereon. Exploded from one end of the explosive, the explosion speed is several kilometers per second, and the titanium plate can collide from the angle of the substrate steel plate by virtue of the explosion. At the collision point, the base steel plate and the titanium plate exhibit fluid behavior due to a very large deformation speed and an ultrahigh pressure, and the oxide film and the gas adsorption layer on the surfaces of the two metals are removed as a metal jet, and the clean surface is cleaned. The joint is completed in an instant, called cold joining. The titanium steel clad plate manufactured by the method can be further hot rolled to a plate thickness of 4 mm, so it is also called an explosion cladding method.

Thick plate rolling

The thick plate rolling method initially assembles a titanium clad plate and a steel plate (substrate) in an embedded slab. At this time, a suitable intermediate insert is placed between the titanium plate and the steel, and electron beam welding is employed under high vacuum. After being heated in a heating furnace, it is strongly pressed to the required thickness on a thick plate mill, so that the titanium plate and the steel plate are actually joined. Finally, the periphery is cut and separated into 2 sheets.

Continuous hot rolling

The continuous hot rolling method is basically the same as the thick plate rolling method. The difference is that the steel sheets are added between the two sheets, arc welding is performed under the atmosphere, and finally, the continuous thickness is continuously rolled to the required thickness on the continuous hot rolling mill to take the coil. Form taken out. Finally, the periphery is cut and separated into 2 sheets.
