Reducing the environmental impact of steelmaking raw materials using mathematical modelling.

The complexity of the steel making process with variability in the quality of raw materials pose huge challenges to operators in delivering performance, productivity and controlling cost. The production and purchasing management teams often make decisions based on existing knowledge and expertise within the organization. It is important that raw material selection is based on their merits and value-in-use for the process and organization. As an example, lime quality has a significant impact on the volume and quality of slag and its ability to absorb impurities. The chemical purity (CaO, SiO2, Al2O3…), loss on ignition, CO2 content, reactivity, and granulometry are a few of the major quality parameters known to be important for slag making. The true impact of each and a combination of these attributes can be quantified using mathematical models based on thermodynamics, lime dissolution, fluid dynamics, mass balance, and heat balance. The model determines the sensitivity of the raw material quality and its overall impact on environment, productivity, the hot-metal ratio, lime consumption, iron loss, steel quality, metallic yield, and conversion costs.
