What effect does drawing have on the performance and organization of medical titanium wire?

With the rapid development of the metallurgical industry, titanium has been popularized and applied as a structural material with high strength and corrosion resistance. In the hydrometallurgical process, because the equipment is exposed to alkali, acid, and various corrosive gases, soot, traditional aluminum alloy, acid-resistant stainless steel, and other materials cannot meet the needs of the production process, which limits the development of hydrometallurgy.

(1) Application of titanium equipment in electrolytic nickel production

In the production of electrolytic nickel, equipment is exposed to solutions with high acid content and active ions, and titanium has excellent corrosion resistance, so it becomes an ideal material for manufacturing electrolytic nickel equipment.

Compared with the stainless steel mother plate, the cathode mother plate in the electrolytic nickel production has a better economic effect and superior performance. For example, the deposited nickel skin is not easy to stick to the plate, easy to peel, the peeling rate is improved, and the starting electrode of the titanium mother plate is flat, Good rigidity, uniform current density during electrolysis, etc. In addition, the heaters, pumps, valves, etc. in electrolytic nickel production equipment also use a lot of titanium materials.

(2) Application of titanium equipment in electrolytic copper production

The cathode rollers of electrolytic copper production equipment were originally steel cathode rollers. Due to the corrosion of the electrolyte, pitting corrosion occurred on the surface of the rollers, which affected the quality of the copper foil, and regular grinding of the rollers also wasted manpower and financial resources. These problems were solved after using titanium rollers. In addition, most of the heaters and cathode motherboards in the production of electrolytic copper are made of titanium.

(3) Hydrometallurgy of other metals

Titanium equipment is also used for cobalt, zinc, aluminum, mercury and other smelting, tungstic acid purification, etc. The main equipment in the metallurgical industry includes electrolyzers, reactors, washing towers, heat exchangers, stirrers, evaporation devices, dust collectors, etc., which Have achieved significant benefits. In foreign countries, when titanium pumps are used to transport chloride, sodium chloride, potassium chloride, and dilute hydrochloric acid, the life of the pump is 5-20 times longer than that of cast iron pumps or stainless steel pumps, and the liquid loss is reduced by three-fifths. Titanium storage in the chlorination workshop The tank can be used for 3-4 years, while the steel storage tank can only be used for 2 months.
