Embodiment 1

[0046] This embodiment is used to illustrate the continuous pickling method of the titanium strip of the present invention.

[0047] The annealed and shot-peened titanium strip is continuously passed through the pre-cleaning, primary pickling, intermediate cleaning, secondary pickling, final cleaning and drying process sections at a speed of 2m / min. The specific steps are as follows:

[0048] (1) Pre-cleaning: introduce the annealed and shot-peened titanium strip into the pre-cleaning tank, spray desalted water on the upper and lower surfaces of the titanium strip through the nozzle on the spray beam device, and remove the metal powder on the upper and lower surfaces of the titanium strip and the metal powder brought out during shot blasting. The steel shot is cleaned, and the water on the surface of the titanium strip is squeezed out with a squeeze roller;

[0049] (2) One-time pickling: guide the titanium belt out of the pre-cleaning tank into the first acid tank. The titani...

Embodiment 2

[0056] This embodiment is used to illustrate the continuous pickling method of the titanium strip of the present invention.

[0057] The annealed and shot-peened titanium strip is continuously passed through the pre-cleaning, primary pickling, intermediate cleaning, secondary pickling, final cleaning and drying process sections at a speed of 6m / min. The specific steps are as follows:

[0058] (1) Pre-cleaning: introduce the annealed and shot-peened titanium strip into the pre-cleaning tank, spray desalted water on the upper and lower surfaces of the titanium strip through the nozzle on the spray beam device, and remove the metal powder on the upper and lower surfaces of the titanium strip and the metal powder brought out during shot blasting. The steel shot is cleaned, and the water on the surface of the titanium strip is squeezed out with a squeeze roller;

Embodiment 3

[0066] This embodiment is used to illustrate the continuous pickling method of the titanium strip of the present invention.

[0067] The annealed and shot-peened titanium strip is continuously passed through the pre-cleaning, primary pickling, intermediate cleaning, secondary pickling, final cleaning and drying process sections at a speed of 4m / min. The specific steps are as follows:

[0068] (1) Pre-cleaning: introduce the annealed and shot-peened titanium strip into the pre-cleaning tank, spray desalted water on the upper and lower surfaces of the titanium strip through the nozzle on the spray beam device, and remove the metal powder on the upper and lower surfaces of the titanium strip and the metal powder brought out during shot blasting.

Abstract

The invention discloses a titanium belt continuous pickling method, and the method comprises the following steps: (1) precleaning, to be more specific, cleaning the upper and lower surfaces of a titanium belt treated by annealing and shot peening; (2) first pickling, to be more specific, using a nitric acid and hydrofluoric acid mixed acid liquid for continuous pickling of the precleaned titanium belt; (3) intermediate cleaning, to be more specific, cleaning the upper and lower surfaces of the firstly pickled titanium belt; (4) second pickling, to be more specific, using the nitric acid and hydrofluoric acid mixed acid liquid for continuous pickling of the intermediately cleaned titanium belt; (5) final cleaning, to be more specific, cleaning the upper and lower surfaces of the secondly pickled titanium belt; and (6) drying, to be more specific, drying the upper and lower surfaces of the finally cleaned titanium belt. The method can improve and control pickled surface quality of the titanium belt, the pickling soluble loss rate can be controlled in real time, and a win-win situation of the pickled surface quality of the titanium belt and yield of the titanium belt can be achieved.

Description

technical field [0001] The invention belongs to a method for chemically treating the surface of nonferrous metal materials, in particular to a continuous pickling method for titanium strips. Background technique [0002] Pickling is a means of chemical surface treatment of non-ferrous metal materials. Its principle is to remove scale and rust on the metal surface through acid solution, and it is a method of cleaning the metal surface. [0003] As a non-ferrous metal, titanium will produce a layer of oxide scale on its surface after thermal processing. The pickling of titanium belt is to dissolve the surface oxide scale with mixed acid solution, and at the same time carry out passivation treatment to prevent the dissolution from accelerating and maintain pickling. The surface of the metal is silver-white. Since TiO is easily formed during thermal processing of titanium 2 Mainly oxide scale, so its pickling method is different from that of steel, but similar to that of stain...
