Method of manufacturing thin titanium/steel composite board

Abstract

The invention discloses a method for preparing a thin-type titanium or steel composite plate, and particularly relates to a method for preparing a composite plate manufactured by the titanium steel-based composite plate through explosion and pack rolling. The method is characterized in that in the preparation process of the thin-type titanium or steel composite plate, the titanium or steel composite plate is compounded and formed by the titanium plate and the steel plate through explosion, then two composite plates are folded and welded into a billet body, and then the thin-type titanium or steel composite plate is formed through rolling. The preparation method adopts the explosive composite process, the rolling billet body has high bonding strength after explosive compounding, the titanium or steel composite plate billet is folded and welded for rolling, and the deformation amount is in 4 to 7 times; therefore, the preparation method not only ensures higher bonding strength of the titanium or steel composite plate after rolling, but also ensures the respective thickness requirements, the prepared titanium or steel composite plate has good processing technological property, the explosive composite billets of the titanium plate and the steel plate after pack rolling have good bonding property, the bending test is performed without layering, the titanium plate surface is free from cracks and impurities, and the method has the advantages of higher bonding strength, corrosion resistance and fatigue resistance.

Description

technical field [0001] The invention discloses a method for preparing a thin titanium / steel composite plate, in particular to a method for preparing a composite plate made of titanium and steel-based composite slabs through explosion and stack rolling. Background technique [0002] For titanium / steel composite plates used in large-scale equipment such as electrolytic cells and reactors in the chemical industry, the substrate and cladding layers are relatively thin. The titanium layer is usually about 1 mm, and the steel plate is usually about 2 to 5 mm. There are currently three commonly used methods for making this type of clad plate: the first type uses the direct explosive clad method, and the titanium / steel clad plate obtained by this method has high bonding strength, but the biggest disadvantage is due to the limitation of the explosive clad process. limitations, the area of ​​the obtained titanium / steel clad plate is small, and it is difficult to level the subsequent cl...

There are currently three commonly used methods for making this type of clad plate: the first type uses the direct explosive clad method, and the titanium / steel clad plate obtained by this method has high bonding strength, but the biggest disadvantage is due to the limitation of the explosive clad process. limitations, the area of ​​the obtained titanium / steel clad plate is small, and it is difficult to level the subsequent clad plate, which cannot meet the requirements of the current equipment; the second type adopts the direct rolling clad method, with this The titanium / steel composite plate obtained by the method has a large plate surface and can meet the requirements of large equipment, but its disadvantages are low bonding strength and high requirements for the capacity of the rolling mill, so it is not widely used in my country at present; the third category The titanium / steel composite plate prepared by this method has a large format and high bonding strength by using the explosion-rolling composite method. However, due to the limited capacity of rolling equipment, it is impossible to directly prepare titanium / steel with a thickness of less than 6mm by using this process. Composite board
