EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

Iron and steel making requires a wide range of different raw materials significantly influencing process performance which demands a continuous optimization of process routes also with respect to energy efficiency as well as environmental emissions. Steadily changing raw material prices and qualities, market situations and product variations are challenging integrated steel plant operators in production planning and cost optimization. In terms of investment planning, detailed knowledge and comparison of possible process routes is necessary. For greenfield investment decisions, a robust comparison of available processes is essential considering all site conditions and raw material specifications. For brownfield investigations detailed knowledge about existing process routes and comparison to desired ones is requested. Up to now steel industry experiences a lack of the possibility in generating robust overall mass and energy balances covering integrated steel plants, concerning both operators and engineering companies. Detailed evaluations by Primetals Technologies proved this situation and led to the development of a holistic metallurgical model library in a flexible flow sheeting environment. This publication will give an introduction to the iron and steel making process integration platform.
