Problems solved by technology

This method can improve the bonding strength of the interface to a certain extent. However, due to the thin coating, elements such as titanium and iron can penetrate the coating under high temperature or long-term heating conditions and form brittle compounds at the interface, which cannot prevent the interdiffusion of elements. At the same time, due to the lack of good ductility of the coating metal, the problem of uneven interface state will be caused during the rolling process, resulting in the quality of the titanium-steel clad plate prepared by this method cannot be well guaranteed

Abstract

The invention relates to the field of titanium steel composite board preparation and machining, in particular to a method for rolling a nickel interlayer titanium steel composite board through the large rolling reduction. According to the technical scheme, the method includes the following steps that symmetric assembling is conducted according to the steel plate/titanium plate/nickel foil/steel plate sequence, the periphery of a blank is welded, the interior of the blank is vacuumized, and then a combined blank is acquired; the combined blank is heated for 120 min to 360 min, wherein the heating temperature ranges from 940 DEG C to 1000 DEG C; the heated combined blank is rolled, and then the titanium steel composite board is obtained. The titanium steel composite board obtained through the method is good in plate cut, no significant defect is formed on the surface, no titanium/iron compound is generated on a bonding interface, the bonding effect is good, and the bonding strength is larger than 230 MPa and is far larger than that of similar titanium steel composite board in the national standard.

Description

technical field [0001] The invention relates to the field of preparation and processing of a titanium-steel composite plate, in particular to a method for rolling a nickel-interlayer titanium-steel composite plate with a large reduction. Background technique [0002] Titanium has good physical, chemical and mechanical properties, but its smelting technology is complicated and the production cost is high, so the price of titanium is very expensive, which greatly limits the promotion and application of titanium. Combining titanium with other metals (such as steel, copper, aluminum, etc.) -Steel composite materials are widely used in chemical, petroleum and other industrial sectors because of their high strength, excellent corrosion resistance and significant economic benefits. [0003] The existing manufacturing methods of clad steel plates include: filling metal ingot rolling method, explosive cladding method, rolling and crimping method, surfacing welding method and the lik...
