The AUTOSLAG application, is a response to EAF steelmakers’ need for EAF automatic slag chemistry management.

AUTOSLAG is a dynamic slag-builders optimisation software tool for the automatic control of slag chemistry in the EAF melting process. The system automatically calculates the Isothermal Stability Diagram (ISD) for a particular slag composition, where the conditions for optimum slag foaming can be achieved.

Based on the chemical analysis of the slag that is automatically received from the slag analyser and the target of the slag’s basicity and chemistry, AUTOSLAG calculates the quantity of slag-builders to be pneumatically injected by dispensers and combined side-wall injectors, during the melting process, in order to keep the slag characteristics within target.
