Embodiment Construction

[0034] Please refer to the attached figure 1 , which shows the flow of a process for producing an ultra-wide titanium plate provided in an embodiment of the present application.

[0035] A kind of processing method of producing ultra-wide titanium plate, described processing method comprises:

[0036] S1 uses a rectangular parallelepiped titanium slab as a raw material, and the original thickness of the titanium slab is 400-500 mm.

[0037] When the traditional process is used to process titanium plates, the titanium round ingot melted in the vacuum consumable electric arc furnace is used as the raw material. Before rolling the coil, it must be forged, and the titanium round ingot is forged into a square with a thickness of about 200mm. ingot. However, forging needs to be carried out at high temperature, and the heat loss is serious; moreover, after forging, the oxide skin on the surface of the titanium ingot is thick, and the surface quality is poor, so it needs to be plane...

Abstract

The invention relates to the technical field of metal material machining, in particular to a technological method for manufacturing a ultra-wide titanium plate. The method comprises the steps that a 400-500 mm thick cuboid titanium flat ingot is adopted as a raw material, and first-time heating is performed on the titanium flat ingot; after heating is completed, first-time rolling is performed onthe titanium flat ingot, wherein transverse rolling is performed, repeated rolling is performed in the width direction of the titanium flat ingot, and a tantalum plate blank with the length meeting the target width requirement and the thickness meeting the requirement for 40-60% of the original thickness of the titanium flat ingot; longitudinal rolling is performed, the titanium plate blank is repeated rolled in the length direction till the thickness is 25-35% the original thickness of the titanium flat ingot; after the titanium plate blank obtained after first-time rolling is naturally cooled, surface treatment is performed; second-time heating is performed on the titanium plate obtained after surface treatment; after heating is completed, second-time rolling is performed on the titaniumplate blank, second-time rolling is longitudinal rolling, and the thickness of the titanium plate blank is 1.5-2.5% the original thickness of the titanium flat ingot. According to the technological method, the ultra-wide titanium plate can be manufactured, the material utilization rate is increased, and the machining period is shortened.

Description

technical field [0001] The present application relates to the technical field of metal material processing, in particular to a process for producing ultra-wide titanium plates. Background technique [0002] Titanium plate is the main product of titanium and titanium alloy processing materials, accounting for more than 60% of the consumption of titanium processing materials. Due to its low density, high strength, corrosion resistance, heat resistance and good toughness, it is widely used in National defense and military industry, aerospace, petrochemical, salt and alkali production, metallurgy, shipbuilding, seaside power stations, seawater desalination, medical treatment and sports and other fields. With the development of the national economy and the advancement of science and technology, especially the improvement of titanium smelting technology, the market demand for titanium plates is increasing. [0003] At present, the wide-width titanium plates on the market are gene...
