Abstract
Recycling pre-oxidized chromite fines in the oxidative sintered pellet production process
Highlights
Stainless steel is a vital modern-day alloy that is well-known for its corrosion resistance, which is mainly due to the inclusion of chromium (Cr) (ICDA, 2013)
FeCr is principally produced in (i) conventional open/semi-closed submerged arc furnaces (SAFs) that are mainly fed with lumpy chromite ore, fluxes. and reductants, (ii) closed SAFs that are fed with oxidative sintered chromite pellets, as well as lumpy reductants and fluxes, (iii) closed SAFs fed with prereduced chromite pellets, as well as lumpy reductants and fluxes, and (iv) closed direct current (DC) arc furnaces fed with fine chromite ore, fluxes, and reductants
Recycling pre-oxidized chromite fines in the oxidative sintered pellet production process perforated steel belt, which carries the pellets through a multi-compartment sintering furnace
Summary
Stainless steel is a vital modern-day alloy that is well-known for its corrosion resistance, which is mainly due to the inclusion of chromium (Cr) (ICDA, 2013). A sample of chromite fines screened out from industrially produced sintered pellets was obtained from a large FeCr producer in South Africa that utilizes the oxidative sintered pellet production process.
