Then the main process of rolling titanium-steel clad plate is compared with the main process of rolling individual titanium or rolling individual steel. It is a unique process for the production of titanium-steel clad plates. The existing raw material billet assembly method cannot ensure that the lamination surface of the cladding titanium plate and the base steel plate is in good condition, and the shear strength of the lamination surface is not less than 140MPa.

Abstract

The invention relates to the technical field of composite plate manufacturing, in particular to a titanium-steel composite plate; the technical problem to be solved by the invention is to provide a method for assembling a raw material blank of a titanium-steel composite plate. A method for forming a raw material blank of a titanium-steel clad plate includes the following steps: A. limiting the value range of the compression ratio; B. limiting the carbon and manganese content of the base steel sheet and the plugging steel sheet; C. removing the base material and the cladding material Oxide film and cleaning treatment; D. Align the base material and the cladding material, apply a release agent between the cladding materials, and weld the cladding materials into a whole; E. Pump the gap between the cladding materials Vacuum treatment and hold pressure; F. Place the cladding material after assembly welding between the lower base materials, and the geometric center of the cladding material and the base material is on a straight line; G. Use the sealing steel plate to weld the base material to make The cladding material is sealed between the sealing steel plate and the base material; H. Vacuum treatment and pressure retention are performed on the gap between the base material.

Description

technical field [0001] The invention relates to the technical field of composite plate manufacturing, in particular to a titanium-steel composite plate. Background technique [0002] The main production methods of titanium-steel clad plate include four kinds: explosive compounding method, diffusion compounding method, explosive compounding-rolling method and rolling compounding method. Among them, the rolling compounding method produces titanium-steel cladding plate with large dimensional freedom and good surface quality. , the dimensional accuracy, productivity and yield are all high, and the shear strength is not much different from that of the explosion-rolled clad plate, eliminating the impact of the explosion process on the environment, and using the large-load rolling mill of the iron and steel plant as the main equipment , it is easy to realize large-scale industrial production, so this method has received more and more attention and attention, and has become a resear...
