Rolling method of titanium steel composite board

Abstract

The invention provides a rolling method of a titanium steel composite board. The rolling method comprises the following steps of: 1, selecting the titanium steel composite board provided with a titanium plate as an upper layer and a steel plate as a lower layer; 2, pre-treating a surface; 3, heating and soaking in a heating furnace; and 4, rolling on a hot mill, and removing scale and cooling by utilizing high-pressure water. According to different physical characteristics of the titanium plate and the steel plate under the high-temperature state, through setting the proper heating and soaking processes, and adopting the high pressure water to remove the scale and cool in the rolling process, an oxide skin on the surface of the titanium steel composite board is greatly reduced, and sundries on the surface of the titanium steel composite board are eliminated, meanwhile, the titanium plate and the steel plate are cooled at different water flows, so that the deformation degree of the titanium plate corresponds to the deformation degree of the steel plate, head buckle or unwarp phenomenon of the titanium steel composite board in the rolling process can be effectively prevented, and damage about a roller is greatly reduced; and the titanium steel composite board, rolled by the invention, has the advantages of clean and tidy surface, no foreign matters to press and good plate cut.

Description

technical field

[0001] The invention belongs to the technical field of metal material processing, and in particular relates to a rolling method of a titanium-steel composite plate. Background technique

[0002] Composite plates are plates of two or more metal materials that are melted and welded together by means of explosion or rolling. Titanium-steel clad plates are melted and welded together by two metals by means of explosion, and then rolled to produce clad plates of various specifications to meet the needs of various fields. Titanium-steel composite plates effectively utilize the excellent properties of titanium such as chemical stability, corrosion resistance and oxidation resistance, and the low-cost characteristics of steel plates. At present, titanium steel composite plate is mainly used in petroleum, chemical industry, vacuum salt making, electric power, shipbuilding, military industry and other fields, and it is a very ideal material.
