Topic: Improvement Of Environmental Protection And Energy Savings by Suitable Material Handling Systems
Abstract: The use of large size silo systems allows a significantly increased storage volume on the same footprint as a conventional stockpile. Each silo can be used for different material qualities and with the use of AUMUND Rotary Discharge Machines (RDM) travelling underneath the silos; every required blend can be extracted by requirement. Such closed storage and material extraction solution suppresses any dust development.
With the use of AUMUND high temperature resistant pan conveyors no additional fines are being generated as there is no relative movement between the conveyor and the hot sinter meanwhile significantly reducing equipment wear and tear.
Thermal insulation transport of Hot DRI in a non oxidizing inert atmosphere significantly saves energy. Energy savings up to 120kW/t liquid steel can be achieved, Tap-to-Tap cycles will be drastically reduced and productivity of EAF increased up to 20%. HBI producing routes are using newly developed and patented HBI cooling method which uses water mist as cooling media thus achieving smother cooling of HBI resulting in stable product quality and final Temperatures below 100˚Cfor optimum downstream handling and storing.
