Production method for industrial pure titanium plate

Abstract

The invention discloses a production method for an industrial pure titanium plate. The production method for the industrial pure titanium plate comprises the steps that (1), a titanium material blankbody is heated, descaled and subjected to at least one time of rough rolling, and a titanium plate blank body is obtained; (2), 5-6 passes of finish rolling is conducted on the titanium plate blank body by adopting a seven-rack hot continuous rolling mill throwing rack, and a titanium plate is obtained; and (3), after the titanium plate is cooled, an industrial pure titanium plate finished productis obtained. By adopting the production method, the titanium plate rolling number can be decreased, the reduction rate of each pass is increased, grains are refined, and the properties of the titanium plate are improved; and meanwhile, rolling consumed oil and cooling water are reduced while the rolling number is decreased, and the rolling cost is reduced.

Description

technical field [0001] The invention relates to the field of titanium plate production, in particular to a production method of industrially pure titanium plate. Background technique [0002] With the development of science and technology, cutting-edge science and technology put forward higher and higher requirements for metal materials. For example, in aviation and aerospace, nuclear reactors have particularly strict requirements on metal materials, which requires the development of metal materials with high temperature resistance, corrosion resistance, wear resistance, high strength, fatigue resistance and light weight. Compared with other structural metals, titanium and titanium alloys have significant advantages such as high specific strength, strong corrosion resistance, good high and low temperature performance, and high fatigue resistance. They have been widely used in aerospace, chemical industry, shipbuilding, marine, automobiles, and weapons. , construction and ot...

Problems solved by technology

[0004] However, the existing finishing mills are generally seven-stand hot rolling mills, and because the thickness of the titanium slab is relatively thin, the rolling reduction allocated to each pass of the seven-stand finishing mill is relatively small, and the plate shape is relatively small. It is difficult to control the thickness, and it is not conducive to the refinement of the grain structure of the titanium plate and the improvement of the mechanical properties of the product
