Abstract

Delivering liquid steel to a steel processing unit at right temperature is an important criterion for high production steel shops, but it is surprising how little attention has been paid in the past to manage this vital phase in the steelmaking process-the steel in transit. The ladle running costs, both directly and indirectly, contribute significantly to the cost of steelmaking and should be an area of concern to any high production steel plant. Here we are talking not only of refractory costs or preheating fuel costs, but also cost of extra heating in ladle furnace, additional process delays incurred in delivering steel at right temperature to downstream unit in case proper care is not exercised at upstream unit, and occasional costs of ladle breakout due to inability to judge the residual life of the ladle. This paper emphasizes the need of a comprehensive ladle management system, an aspect which has not been properly addressed in the operations of a steel plant, in improving the productivity of a steel melt shop. Starting with review of present status and the attempts at implementation of ladle tracking in steel melt shop automation system, it looks at components of an exhaustive Ladle Management System (LMS), and finally gives an idea of benefits that will accrue from implementation of such a system in a steel melt shop.
