SUMMARY:Process model for thermal ladle status as part of an online ladle management system for steel melt shops
DESCRIPTION:Disadvantageous temperature management of ladles and their contained melts have a negative effect on energy consumption, throughput, and yield. In particular, the caster is highly influenced by any deviation from target temperature, which may come along with either low casting speed at high temperatures or even casting abortion at low temperatures. In this contribution, we present a solution for tracking ladle temperatures in a steel melt shop. In detail, the SMS group GmbH has developed an L2 process model to represent the current thermal state of each ladle in circulation in real time. This involves also empty ladles in waiting position. In addition, predictions on the melt and refractory temperatures can be performed, based on the planned process routing, which in turn define trimming values on standard target temperatures. The process model solves the heat conduction equation by means of the finite volume method in either 2D or 3D, whereby effects such as changes of the melt level, stirring of the ladle, or alloy additions are reflected. Moreover, model adaption to actual measurements from process and/or the coupling to other process models is possible. During production, the model receives actual process and equipment data (treatment times, alloy additions, refractory materials, heating power, …), as well as information on planned routing via a predefined database interface. The obtained computational results of the process model can be used in a variety of ways, in order to improve process performance, e.g. cost reduction at the primary aggregate, increase of throughput, or avoidance of ladle returners.
