7TH EUROPEAN COKE AND IRONMAKING CONGRESS - ECIC 2016

An increasing demand in flexible process variations, raw material utilisation, internal by-product and waste material recycling in iron and steel production together with the needs for standardisation to partners and interfaces with equipment suppliers requires new and intelligent platforms for mass and energy balancing based on a flow sheeting approach. Following an evaluation on state of the art process simulation programs, Primetals decided to develop a comprehensive metallurgical flow sheet model library for simulation of integrated steel plants. Intensive development efforts were taken in order to migrate existing well established calculation and engineering routines as well as integrate newly developed models. The generated model library enables the setup of mass and energy balances for integrated steel plants, development and evaluation of new process concepts as well as investigations on impacts of raw material changes and trace material distributions. By using this process integration platform, it is possible to compare different iron and steelmaking routes within one standardized environment. Additional benefits from the use of a modern flow sheeting tool are flexible adaption of process routes, clearly represented plant depictions as well as robust and well defined calculation routines.
