Romelt process in particular represents one of the most promising and perspective trends of iron production from various iron bearing materials.
Romelt process is metallurgical technology of future!
Romelt process (liquid-phase iron reduction process) has been developed at the Moscow steel and alloys institute. This technology represents continuous single stage process of iron production from various iron bearing raw materials as well as inplant metallurgical wastes with utilization of cheap power and non-coking coal grades.
Romelt process is characterized by the following main advantages:
Romelt process is characterized by several advantages compared to traditional iron production technology:
Listed below are main Romelt process features, which principally differ from currently utilized and being developed liquid phase reduction (smelting-reduction) technologies:
Romelt process represents not only alternative of traditional iron production process using sinter-coke-blast furnace route but as well as the excellent supplement of the latter. Romelt process and furnace offer principally new, high-performance technology and design of production unit for reduction melting of iron bearing raw materials with production of liquid iron-carbon semi-product for subsequent steel making.
Flue gases heat is to be used in waste heat boiler for steam production and subsequent power generation. In case of low post-combustion degree flue gases can be used as a fuel or reducing agent. If secondary power generation is not required, flue gases’ heat can be used at a combined Romelt unit for steel scrap melting or preliminary ore heating. This means that Romelt process is practically wasteless.
The above listed Romelt process advantages allow to establish steel industry in countries having iron ores with low Fe content and absence of coking coal, which was not possible before.
