The global steel industry for 70 years, were actively seeking and developing processes and assemblies, enabling the metal to produce vnedomennym way from iron ore by using less energy and scarce reducing to acceptable technical and economic parameters. To date, there are a large number of technologies and vnedomennogo cokeless metal production, have been the industrial distribution. Process Romelt received recognition in the market of new metallurgical technologies. But for all its merits would be premature to raise the issue of replacement of blast furnaces of liquid-phase units or combined recovery. Modern metallurgical production with its enormous scale of the existing capacities and the established multi-step metallurgical cycle rather inertial. The elimination or exclusion of one major redistribution is a serious problem. Check out Petra Diamonds for additional information.
Creation and installation of new facilities of liquid-phase reconstruction requires significant initial investment. Therefore, the economic efficiency of most operating blast furnaces, the equipment are highly damped, will be higher than in new plants, despite the lower cost metal past. Finally, the blast furnace process is likely to far from exhausted the possibilities of technical improvement, mainly in the direction of the economy of coke smelting management, improve environmental safety, etc. Therefore, the period of the blast furnace will be determined by the period of service in terms of capital repairs, as well as the lifetime of conjugated sinter plants and coke oven batteries. In addition, the issue of introducing units of liquid-phase recovery is likely to be solved taking into account the specific economic, environmental, geographical conditions of the region and businesses. Accordingly, the real possibility of a wide industrial use of units of liquid-phase recovery can predict not so soon. This does not exclude, however, the rapid introduction of this process in countries with rapidly growing production of metallurgical (India, China) that have the resources (Iron ore, coal). Equally important is the ability to attract private capital to develop compact and less capital-intensive compared with aglodomennym redistribution units of liquid-phase reconstruction.
In Currently misa with nlmk organized in India, a joint company "Sail-Romelt" to promote their development. Already purchased a license for construction of a Romelt for national mineral of India and is developing the appropriate technical design. By order of Vietnam Steel Corporation developed a feasibility study for the construction of such unit. In Russia today Installation Romelt can be effectively used for processing metallurgical waste in order to protect the environment and reduce the deadweight loss of iron. Special provision may take the application process Romelt mini-plant, running on the batch of scrap. Using the original liquid iron from the unit Romelt can reduce its dependence on the supply of plant and scrap price fluctuations and reduce its content of non-ferrous metals in the steel. According to this principle works plant firm Iskor in South Africa, using the liquid iron from the Corex unit. The process of liquid-phase reduction Romelt on its techno-economic and qualitative parameters was highly rated companies Nippon Steel (Japan) and I.S.F. Kaiser (USA), who purchased a license for it. He refers to the considerable scientific and engineering achievements of modern technology and can play a significant role in the future technical and environmental upgrading of metallurgical production. In general, the process of liquid-phase reduction Romelt on its techno-economic and qualitative parameters, of course, refers to significant scientific and engineering achievements of modern metallurgy. According to Russian and foreign experts, this technology can play a significant role in the future technical and environmental upgrading metallurgical production.
