ROTARY HEARTH FURNACE TECHNOLOGIES FOR IRON ORE AND RECYCLING APPLICATIONS

摘要

Midrex Technologies and Kobe Steel offer the FASTMET~R, FASTMEL~R, and ITmk3~R Technologies for processing iron ore and iron-containing by-products to produce DRI and pig iron products. These processes offer steelmakers methods for economically producing high quality iron products and recovering valuable mineral resources using fine ores, by-products, and coal. Several commercial FASTMET Plants have been operating successfully for a number of years, confirming the basic process concept. A number of new projects are under development worldwide for the three technologies. This paper provides technical details of the processes, reviews promising applications, and discusses current commercial developments.
