Abstract

The invention provides a preparing method of a wide-width pure titanium roll. The preparing method includes the following steps: 1 pure titanium slabs with a certain specification are subjected to annealing in the air and acid-washing; 2 10-20 acid-washed pure titanium slabs are welded to form a roll to obtain a pure titanium coiled slab; 3 a 1780mm six-roller reversing cold mill is adopted to roll the pure titanium coiled slab to obtain a pure titanium rolled coiled slab; and 4 the pure titanium rolled coiled slab is sequentially subjected to oil removing, annealing, flattening and shearing to obtain the wide-width pure titanium roll with thickness to be 0.5-3.0mm and the width to be 1000-1500mm. The preparing method is simple in process and simple and convenient to operate, needs no special or complex devices, and can achieve large-scale industrial production by aid of conventional devices. The wide-width pure titanium roll prepared in the method fills the gap in domestic pure titanium roll products, breaks through technique blockade of foreign pure titanium roll products, shortens the gap of domestic technology and the international advanced technology, and powerfully promotes pure titanium material development.

Description

technical field [0001] The invention belongs to the technical field of metal material processing, and in particular relates to a preparation method of a wide-width pure titanium coil. Background technique [0002] Pure titanium coils are widely used in aviation, aerospace, nuclear power plants, chemical industry, construction and other fields. Its products include thin titanium plates for heat exchangers, titanium plates for composite plates, titanium plates for welded pipes, titanium plates for construction, etc. At present, several sets of titanium tube welding production lines have been built in China, but the upstream product of titanium tube production, pure titanium coil, mainly relies on imports from abroad. The price level of pure titanium coil raw materials imported from abroad is almost equivalent to the price of domestic titanium welded pipe products, which makes the development of the entire domestic titanium welded pipe market slow and cannot be widely used. ...
