Production of FeCr and FeCrNi Alloys with an Energy Saving Route

The stainless steel industry is increasing at a great pace every day. In addition, there is a need to increase the production capacities of FeCr and FeNi, which are the main input raw materials of stainless steel. However, FeCr and FeNi production processes with intensive energy consumption and high carbon dioxide emission values pose a problem when evaluated within the framework of the Paris Climate Agreement. As a result of these reasons, more environmentally friendly and more economical methods are sought. In this study, FeCr is produced by aluminothermicAluminothermic reaction to reduce the carbon footprint to almost zero in the smelting process and energy savingEnergy saving is aimed by exothermic reaction. In addition, FeCrNi production conditions were investigated by smelting in a single crucible instead of separately produced FeCr and FeNi. In addition, energy saving is achieved as it is fed in powder form without applying any agglomeration process as a preliminary preparation.
