デュエルビッツ プロモーションコードel has developed the ITmk3® Process, which produces high-purity granular iron by utilizing デュエルビッツ プロモーションコード-coking coal. The ITmk3® Process is distinctive with reduction, carburizing, melting and slag separation occurring promptly at lower temperature.
デュエルビッツ プロモーションコードTmk3® Process completely bucks conventional concepts of ironmaking. デュエルビッツ プロモーションコードel regards it as the third generation of ironmaking technology, following the current major blast furnace-basic oxygen furnace (BF-BOF) process and the direct reduction (DR) process represented by the Midrex® Process. デュエルビッツ プロモーションコードTmk3® Process can make reduction reaction take place in approximately 10 minutes, compared with 8 hours by the BF-BOF process and 6 hours by the DR process.
In the current iron ore market, the effective utilization of low-grade iron ore is an issue, as it has become more and more difficult to secure high grade iron ore. At the present, low-grade iron ore is processed into iron ore fines, high-grade iron ore concentrate and pellets through grinding, beneficiation and firing, and is fed into the blast furnace and DR plant. In デュエルビッツ プロモーションコードTmk3® Process, デュエルビッツ プロモーションコード-coking coal are mixed together and agglomerated into green pellets. These pellets, fed into a rotary hearth furnace (RHF), are changed into granular iron, namely Iron Nuggets, through reduction and melting occuring at a stroke.
Furthermore, デュエルビッツ プロモーションコードTmk3® Process utilizes non-coking coal as the reductant, which is abundant in volume worldwide in comparison to metallurgical coal utilized by blast furnaces. Therefore, デュエルビッツ プロモーションコードTmk3® Process not only widens the sourcing of coal procurement but also decreases the environmental impact by eliminating the coking coal process required for blast furnaces.
Overcoming various difficulties, the utilization of non-coking coal as a reductant for low-grade iron ore is embodied by デュエルビッツ プロモーションコードTmk3® Process. This process is gaining attention all over the world as a breakthrough technology owing to the following advantages: reducing the cost for ironmaking, widening the range of raw materials for the process, and reducing the burden on the environment.
デュエルビッツ プロモーションコードel has constructed the world`s first commercial plant in Minnesota, USA in cooperation with Steel Dynamics Inc. (SDI)
High-purity iron units are required to produce high grade steel products, while the availability of such resources is becoming tight. Steel producers need to secure a stable supply of high-purity iron, and Iron Nuggets produced by デュエルビッツ プロモーションコードTmk3® Process can offer solutions with its great advantages.
