AbstractLD process of stealmaking accounts for 70% of steel production throughout the world. Due to various constraints like the complexity of LD process; variation in quantity, quality and grade of input materials; varying operating conditions, random parameters and their values; the interventions of an expert and skilled operator is necessary to tackle the complex situation. To overcome this, there exists, a need of a system, which does not only possess the process control capabilities, but also emulates operator's expertise in terms of his knowledge and skill. Such a system has been developed named “Expert Steelmaker”. The paper discusses the “Expert Steelmaker” which can presently be used in an advisory mode by the LD steelmaking operator.Indexing terms: Expert systemLD steelmakingProcess controlCharge calculationsMaterials and energy balance Additional informationNotes on contributorsP N MishraP N Mishra did his MSc (Tech) in Instrumentation from BITS, Pilani.
