Iron ore sintering is an agglomeration process, which combines fine mineral particles into a porous mass by partial liquefaction caused by heat generated from coke breeze …
It was developed by Paul Wurth. The EFA process is installed at the end of the sinter plant process. It essentially consists of an entrained flow absorber and a bag-type filter. Using this equipment, from the sinter plant off-gas, dust, sulphur oxides, hydrochloric, hydrofluoric acids, dioxins and furans are captured.
12.5.1 Process Description1-3 The production of steel at an integrated iron and steel plant is accomplished using several interrelated processes. The major operations are: (1) coke production, (2) sinter production, (3) iron production, (4) iron preparation, (5) steel production, (6) semifinished product preparation, (7) finished
