Problems solved by technology

In the production process of explosion + rolling compound method and rolling compound method, the slab needs to be heated and kept warm before rolling. During the process of heating and keeping warm, the bonding interface will generate brittle compounds such as TiC, TiFe and TiFe 2 , the formation of compounds will reduce the bonding strength of the clad plate. The existing explosion + rolling clad method and rolling clad method to prepare titanium steel clad plate need to use a heating furnace to heat and keep the billet for a long time. The longer the time, the bonded The more compounds generated at the interface, it will seriously affect the bonding strength of the composite plate
[0004] In the existing hot-rolling and compounding technology for preparing titanium steel clad plates, the heating temperature of the billet is generally above 850°C, and it is difficult to compound at low temperature.

Abstract

The invention provides a method for preparing a titanium-steel composite plate by adding a pure iron interlayer through electromagnetic induction heating rolling. The method comprises the following steps: S1, cutting a plate blank and carrying out surface treatment; S2, assembling and fixing the composite plate blank; S3, carrying out argon protection; S4, carrying out induction heating of the composite plate; and S5, carrying out rolling. The characteristics that pure iron interlayer metal is good in mobility and easy to combine with pure titanium and carbon steel are utilized, electromagnetic induction heating is adopted to replace traditional resistance wire heating furnace heating to achieve rapid heating of the composite plate blank in the protective gas atmosphere, the production process is simplified, the titanium-steel composite plate has a certain temperature difference through electromagnetic induction heating, the warping degree of the rolled composite plate blank is reduced, and the titanium-steel composite plate with high bonding strength and good deformation coordination can be efficiently prepared.

Description

Technical field[0001]The present invention relates to a method of manufacturing a metal composite sheet, and more particularly to a method of adding a pure iron intermediate layer electromagnetic induction heating rolling to prepare titanium steel composite panels.Background technique[0002]Titanium is used in large quantities of various chemical reaction vessels and heat exchanger materials due to its excellent corrosion resistance, but the disadvantage is costly. In particular, this problem is especially prominent as structural components, and effective solution is to use titanium steel composite panels. The titanium steel composite panel combines valuable metal titanium plates with inexpensive steel sheets, and both titanium corrosion resistance, and steel sheets as structural strength, it is important that the cost is greatly reduced.[0003]The main method of preparing a titanium steel composite plate has explosive compounding, explosive + rolling composite method and rolling comp...
