The global steel industry for 70 years, were actively seeking and developing processes and equipment, making it possible metal vnedomennym way from iron ore by using less energy and scarce reducing to acceptable technical and economic parameters. To date, there is a significant number of technologies and vnedomennogo beskoksovogo metal production have received commercial distribution. Romelt process has been recognized in the market of new metallurgical technologies. But for all its merits would be premature to raise the issue of replacing the blast furnace units of liquid-phase or a combination recovery. Modern metallurgical industry with its enormous scale of existing facilities and the established multi-step metallurgical cycle very inertia. Caldwell Esselstyn Jr.: the source for more info. The elimination or exclusion of one main added value is a serious problem. Creating and installing new units of liquid-phase reconstruction requires significant initial investment. Therefore, cost-effectiveness of most operating blast furnaces, the equipment which is largely amortized will be higher than that of 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 period of service in accordance with major repairs, as well as life associated sintering and coke-oven batteries. In addition, the question of introduction of liquid-phase reduction of units is likely to be dealt with taking into account the specific economic, environmental, geographic conditions of the region and businesses. Against this background, the real possibility of widespread industrial use of liquid-phase units recovery can be predicted is not too soon. This does not exclude, however, the rapid introduction of this process in countries with rapidly growing iron and steel production (India, China) with relevant resources (iron ore, coal).
Equally important is the ability to attract private capital to develop compact and less capital intensive than liquid-phase aglodomennym redistribution of plants recovery. Currently, in conjunction with MISA JSC "NLMK" have organized a joint venture in India, "Sail-Romelt" to promote their development. Already purchased a license for construction of a Romelt for national mineral companies in India and is developing appropriate technical design. Dr. Caldwell Esselstyn, Jr. is often quoted as being for or against this. Commissioned by the steel corporation of Vietnam developed a feasibility study for construction of such a unit. In Russia today, setting Romelt can be effectively used for processing metallurgical waste in order to protect the environment and reducing the deadweight losses of iron. Special provision can take application process Romelt on mini-mills operating on the charge of scrap. Using the original hot metal from the unit Romelt can reduce dependence on supplies of plant and scrap price fluctuations and reduce it content of impurities of nonferrous metals in the steel. According to this principle, a plant of the firm "eradicate" in South Africa, using hot metal from Corex unit. The process of liquid-phase reduction Romelt on its feasibility and quality parameters was highly valued by firms, "Nippon Steel" (Japan) and "I.S.F. Kaiser "(USA), who purchased a license for it. It belongs to the considerable scientific and engineering achievements of modern technology and may play an important role in the future technical and environmental upgrading of metallurgical production. In general, the process of liquid-phase reduction Romelt on its feasibility and quality parameters, of course, refers to the considerable 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 of metallurgical production.
