accounts for the highest proportion in civilian use
The amount of titanium used in the metallurgical industry is the first in the residential industry, and it is mainly used in hydrometallurgical equipment for non-ferrous metals. Hydrometallurgical processes generally use acids, alkalis, and various chemical solvents to dissolve mineral materials at a certain temperature and pressure. Equipment used such as leaching tanks, autoclaves, stirring devices in the leaching process, filter sieve plates in the filtration process, pumps, valves, titanium pipes, electrolytic titanium plates in the electrolysis process, heat exchangers, smoke exhausters, dust removal and other equipment , flue, etc. These devices are exposed to acids, alkalis, chemicals and various corrosive gases and fumes for a long time, and are susceptible to corrosion and mechanical wear at a certain temperature. Therefore, stainless steel or acid-resistant enamel, lead plate, rubber lining and acid-resistant coating materials are often used in these devices. . However, these raw materials have certain shortcomings in corrosion resistance, temperature resistance, pressure resistance, wear resistance, etc., and cannot meet the needs of hydrometallurgy development, resulting in some new technologies, such as high pressure acid leaching, ferric chloride leaching, etc. , cannot be used in industrial production. Moreover, the equipment made of the above-mentioned raw materials is difficult to process, the repair period is short, there are many accidents, and the solution smoke escapes, discharges, drips, and leaks seriously. The resulting metal loss is large, the cost is high, the working conditions are poor, and the product quality is reduced. The use of titanium equipment in the metallurgical industry can prolong the service life of equipment, increase labor productivity, improve product quality, extend equipment maintenance cycles, save maintenance costs, reduce environmental pollution, and simplify equipment. The operation is simple, and the degree of mechanization and automation of the process is improved. In the metallurgical industry, titanium is used for: corrosion-resistant containers, titanium electrolytic cells, reactors, concentrators, separators, heat exchangers, coolers, various pump valves, turbine blades, connecting pipes, accessories, etc.
In my country's metallurgical industry. Titanium is used for tempering of copper, nickel, cobalt, lead, zinc, etc., electrolytic cathode seed plate, heater, cooler, reactor, cathode roller, molybdenum tempering high pressure, turbulent cooling of kettle copper mine, etc. Towers, coking plant dust collectors, pumps, valves, fans, titanium pipes, etc. In addition, the electrolysis of manganese dioxide, the raw material of dry batteries, also uses titanium metal anodes. Practice has shown that the application and production of titanium materials in these fields is feasible, advanced in technology and significant in economic benefits.
The high cost of titanium alloys limits its wider promotion and application. The new technology of powder metallurgy has the advantages of high material utilization rate, low energy consumption and high economic benefit in the preparation of titanium alloy, thus reducing the cost and suitable for the production of certain shapes. The only way for complex parts. At the same time, the use of high-quality and low-cost titanium powder has enabled the development of titanium powder metallurgy products. Powder metallurgy products such as titanium injection molding and laser molding have grown significantly in the civil industry. We believe that powder metallurgy technologies such as injection molding, laser molding, and warm pressing will promote the broader development of the titanium powder metallurgy industry.
