Reduction of CO2 Emissions in Steelmaking by Means of Utilization of Steel Plant Waste Heat to Stabilize Seasonal Cooling Water Temperature

Production of overall CO2 emissions has exhibited a significant reduction in almost every industry the last decades. The steelmaking is still one most producers worldwide. processes and facilities used at steel plants, such as blast furnace electric arc furnace, generate large amount waste heat, which can be recovered meaningfully used. Another way to reduce number low-quality products which, due poor final quality, need scrapped. Steel product quality strongly dependent on continuous casting process where molten converted into solid semifinished slabs, blooms, or billets. It was observed that crack formation affected by water cooling temperature for spray varies during year. Therefore, proper determination prevent occurrence defects. main idea based utilization heat inside plant preheating Continuous Casting (CC) terms stabilization. This approach improve contribute greenhouse gas emissions. results show that, case billet casting, consumption also reached. presented tools achieving these goals are laboratory experiments advanced numerical simulations process.
