Optimisation of Ferro Alloy Usage in Steelmaking

Das, A K and Mukherjee, T (1996) Optimisation of Ferro Alloy Usage in Steelmaking. In: UNSPECIFIED.



Ferro alloys constitute one of the most expensive inputs to steelmaking.Their contribution to cost depends on the type of steel. However, with respect to the product mix of a typical Integrated Steel Plant, it amounts to 7-10% of the cost of saleable steel. Optimisation of ferroalloys not only involves minimising specific cost but must also address to the issues of customer satisfaction. With the progress of knowledge in the area of material science and growing competition, subjects like residuals in ferroalloys are gaining importance. The task of optimisation is multifaceted and requires actions in a number of areas like (i) steelmaking practice - deoxidation, slag-carry over etc., (ii) quality of ferroalloys - chemistry,size, residuals, (iii) cost affective design of steel, ( iv) downstream processing of steel - heat treatment, etc., (v) Selection of ferroalloys, and (vi) Distribution and control within the plant. The paper discusses the above aspects based on informationldata from real-life situations.
