A processing method for preparing titanium anode plates from pure titanium slabs

Abstract

The invention provides a processing method of a titanium anode plate made of a pure titanium plate blank. The processing method is a method controlled by a whole processing chain actually; the titanium anode plate is prepared after the hot rough rolling, hot finishing, annealing, acid washing, cold rolling, uncoiling and slitting, sizing and atmospheric annealing are performed on the pure titanium plate blank; the thickness tolerance of the titanium anode plate is less than 0.10 mm, the inequality is controlled to be within 5mm / m, and the grain size evaluated according to the GB / T6394-2002 standard is between 6 and 8. The processing method provided by the invention is characterized in that the manner of combining the coiled material rolling with atmospheric annealing is adopted, requirements to the thickness of the titanium anode plate is controlled accurately, the grain size of the titanium anode plate is positioned at an international higher level, the atmospheric annealing has general applicability, the production cost is reduced, the production period is shortened, and the titanium anode plate finally prepared through the processing method can meet use requirements of the titanium anode plate from characteristics of uniform thickness, less inequality, small grain size and the like after comprehensive consideration.

Description

technical field [0001] The invention belongs to the technical field of material processing, in particular to a processing method for preparing titanium anode plates from pure titanium slabs. Background technique [0002] Titanium anode plates are widely used in the fields of electrochemistry and electrometallurgy due to their excellent corrosion resistance, low cost, high specific strength and excellent machining characteristics. Usually titanium anode plates are made of pure titanium slabs after heating Rolling, annealing, pickling, cold rolling, cut-to-length, and vacuum annealing and other multi-channel processing processes, there are high requirements for titanium anode plates in use. For example, titanium anode plates are required to have uniform thickness, small unevenness, and crystal characteristics such as fine grain size. [0003] Chinese patent 201210319732.8 discloses a creep correction method for titanium and titanium alloy plates. In this method, a form correc...
