Recently, Panzhihua Iron and Steel to declare a "comprehensive utilization of Panzhihua vanadium titanium magnetite complete technology and equipment research" subjects successfully passed the national "Eleventh Five Year" science and technology research project subject to review, which is in Panzhihua Vanadium and Titanium in the comprehensive utilization of resources for the a breakthrough to improve the efficiency of mineral resource use to upload new Good news. In recent years, Panzhihua Iron and Steel successfully developed with independent intellectual property rights of high tech, titanium vanadium greatly improved the comprehensive utilization of resources, so that the former can not take full advantage of the valuable resources "fossil as the gold," VN V Ti alloy and other products an annual increase of more than 10 billion yuan sales income. Panzhihua is located in the Panxi area, hold vast amounts of vanadium titanium magnetite, in which the country's total reserves of vanadium 87%, 11% of the world's titanium reserves accounted for 94% of the country, the global 35%. As a resource based development and utilization of industrial enterprises, the existence of Panzhihua Iron and Steel had long outstanding problems in the low utilization rate of resources, particularly among the low utilization rate of vanadium titanium resources particularly at night, was dubbed the "eat bean dregs, lost tofu" . In the Panzhihua rich high titanium magnetite in the vanadium and titanium, vanadium titanium magnetite iron grade is low, and many other rare metal vanadium titanium magnetite associated resources as ore facies special structure, dressing, smelting, separation, and Recycling is difficult, requires high technology. Panzhihua Iron and Steel Although some people to break the foreign Panzhihua magnetite can not be smelt on the "spent ore" and asserted that to solve the ordinary blast furnace smelting of vanadium titanium magnetite problem, but subject to technical conditions at that time limitations, the use of the level of vanadium and titanium is very low. Jin Gui vanadium titanium, "Baby" in production have been in vain due to inability to recover discarded, while the national economic construction in a critical mass of vanadium and titanium products have to be imported. The face of this situation, Panzhihua Iron and Steel to resource development and resource conservation combine, relying on independent innovation, in the full use of these valuable resources to play its comprehensive benefits carried out fruitful exploration. Panzhihua Iron and Steel's science and technology workers determined to have been monopolized by foreign long term recovery of vanadium and titanium technology, expand research, at the national departments attach great importance to and support of technological innovation in Panzhihua Iron and Steel arduous efforts finally bear fruit: a group of independent intellectual property rights The high tech, patent to fill the domestic blank, some of which the outcome of the world leading level, and has won the national first prize for scientific and technological progress, the State Technological Invention Award second prize, the National Science Conference Award, Metallurgical Science and Technology Award Grand Prize and so on, use of resources efficiency increased dramatically. Panzhihua Iron and Steel after 10 years of sustained efforts to overcome a series of technical difficulties, selected from the selection of titanium iron ore tailings, and continue to break through international fine class dressing restricted area, titanium used from zero to more than 30 million tons of annual output . Panzhihua Iron and Steel previously re election flotation magnetic separation titanium electric election process can only be recovered over the coarse grained ilmenite 0.045um to enter the election process of titanium is less than 58% of the fine titanium iron 0.045um Mine have been in vain discarded, resulting in low utilization rate of titanium resources. But less than 0.045um micro fine titanium technology, because of ilmenite and titanium pyroxene difference is small, separation is difficult, not easy to concentrate, mineral composition is more complex characteristics such as mineral processing industry has always been the world's technical problems. Panzhihua Iron and Steel production early, after nearly a decade of experiments and exploration, invented the atomization process of vanadium. Formally established in 1978, two atomization of vanadium furnace, Panzhihua Vanadium atomization to mention put into production, so that importing countries of China's leap from the vanadium into vanadium exporting countries, for China's industrial development has created conditions for vanadium. In 1995, Panzhihua Vanadium invented more advanced than the atomization of vanadium converter, and built a 2, 120 tons annual output of 110,000 tons of vanadium slag vanadium standard converter to solve the atomization of vanadium hot metal processes are difficult to resolve the temperature is low, high sulfur problems, improve the overall recovery rate of vanadium and vanadium slag quality. Vanadium nitrogen alloy is an important alloying additive, its production technology is a representative of the direction of the world's vanadium industry leading technologies. Panzhihua Iron and Steel in the domestic first developed with independent intellectual property rights and the international advanced level of V N alloys. The project addressed vanadium nitrogen alloy industrialization of research results difficult problem, in the stability of continuous production technology under normal pressure, catalyst selection and application technology, binder and forming pressure on the optimization of reduction temperature control and TBY furnace design will have a major innovation, for a number of invention and utility model patents. Research and development of the vanadium nitrogen alloy industrial production technology is reasonable, formed with the product development, production and application of a series of related detection technology and enterprise product standard, it has had 2,000 tons year production capacity. Products have been successfully applied HRB400Mpa, 500Mpa grade steel, P510L girder plate, N80 non quenched and oil pipes, 09V310 B type steel and high speed tool steel such as steel, significantly improved the performance of steel to raise the level of China's vanadium industry and international competitiveness to promote the iron and steel, construction, automobile, petroleum and other industries technological progress, economic and social benefits are very significant. Currently the world's only U.S. company and Panzhihua Iron and Steel master this technology. Series of vanadium and titanium through the implementation of new technologies, Panzhihua Iron and Steel after nine years of hard work has built a world class micro fine particles of titanium ore production line, annual production capacity of 14 million tons, to December 2005 have been produced more than 400,000 of titanium ore tons, the output value more than 200 million yuan. Panzhihua Panzhihua Iron and Steel and Chongqing also, Jinzhou have set up specialized titanium dioxide producer, so that titanium dioxide production capacity reached 7.2 million tons. With the "vanadium converter" as well as vanadium pentoxide, vanadium oxide, vanadium iron and vanadium nitrogen alloy production technology with independent intellectual property rights of high tech and manufacturing processes and continuously improve product quality, increasing resource industries Panzhihua Vanadium grow, at one stroke to become the world's second largest producer of vanadium business, vanadium products occupy 80% of the domestic market share in the international market of 20%. Panzhihua Iron and Steel in recent years has invested more than 500 million yuan for the independent research and development, have developed a broad market prospect of vanadium, titanium products, titanium resources to make the recovery from 15% to about 27% of the current, comprehensive utilization rate from the previous 4.5% to 14.3%; vanadium resources, comprehensive utilization rate has reached over 50%. Resources, make full use of vanadium and titanium, as well as the formation of the industrial chain, not only the achievements of the Panzhihua Iron and Steel "China Vanadium and Titanium City" reputation, but also driven to enhance the comprehensive utilization of other resources. Meanwhile, the Panzhihua Vanadium products actively promote the application of technology, selected Baosteel, Shougang, Jinan Iron and Steel, heavy steel, Lianyuan Steel more than 10 major domestic steel companies to promote steel as a technology demonstration unit, free of charge to provide them with products that do experiments V , and sent technical staff guidance. Currently, the production of vanadium containing steels are a number of large scale construction projects for domestic "downsizing." It is reported that the use of greater strength and seismic performance of a special steel containing vanadium, only the Beijing Olympic Stadium "Bird's Nest," a project in the amount of the steel from the original eight thousand tons to four thousand tons, while its security performance and seismic performance remain unchanged. This year, the Panzhihua Iron and Steel also set up, including mineral resources, vanadium titanium smelting, chlorination process titanium white R & D, sulfuric acid such as titanium dioxide and vanadium 5 units comprehensive utilization of resources, including research teams, and established bands mill order selection sound and technology promotion, vanadium titanium magnetite in the following 1000m3 blast furnace smelting technology to improve and project identification, vanadium titanium magnetite non blast furnace ironmaking technology research, 2000m3 blast furnace raw materials and smelting technology research, chlorination of raw materials Preparation of Titanium Dioxide and other key projects. Up to now, in the vanadium titanium non blast furnace ironmaking technology, research, completed a 200KVA electric arc furnace slag and molten iron separation test points, melting points of deep reduction furnace tests; vanadium titanium magnetite in 1000m3 blast furnace below carried out in the climbing Cheng Gang industrial experiment was a complete success; in 2000m3 blast furnace raw materials and smelting technology research, the completion of raising the ratio of pellets into the furnace industrial test; in the chlorination process titanium dioxide prepared by the technical aspects of raw materials and completed the expansion of the system to take PUS Test at the same time, through research, anatase titanium dioxide to enhance product quality, superior product rate totaled 45% or more; red cell mineral utilization to form a preliminary program; rank order selection grinding transformation has been in operation for eight milling system to achieve research goals, concentrate grade of over 54%, ore to Taiwan, more than 20% increase in production. Industry experts say that at present, the comprehensive utilization of Panzhihua Vanadium and Titanium Resources in China ranks leading level, and quite a number of technology and equipment level has been among the world's leading ranks. As the reality conditions, tailings 0.019um of ultrafine particles of titanium resources, blast furnace slag in Vanadium and Titanium Resources are still unable to recover millions of tons of tailings per year, high slag can accumulate in the valleys among the accumulated hundred million tons, how to further make full use of tailings, blast furnace slag in Panzhihua Vanadium and Titanium Resources to become the subject of a new person. To this end, in the "Eleventh Five Year" period, Panzhihua Iron and Steel in line with priorities and focus on developing the idea of vanadium and titanium industry, established in the industrial development strategy, it should be the world's largest vanadium industry, the strongest, we should do titanium industry China's largest and strongest targets to further enhance the efficient use of resources. It is reported that Panzhihua Iron and Steel will further enhance the grade of iron concentrate, tailings, the table outside the mine, and other difficult to use mine for development and utilization of micro fine grade titanium to expand production capacity, to achieve full vanadium hot metal to substantially improve the efficiency of resources utilization .
