Development of a Simulation Model of Cutting Slabs in a Continuous Casting Machine

Abstract

In the article the development of a simulation model of cutting slabs in a continuous casting machine is considered. Simulation modeling is used to optimize the sequence of the melts supplied to the continuous casting machine. The goal of optimization is to reduce the deviation between the estimated and actual numbers of slabs, because such deviations can lead to missed deadlines. The model of cutting slabs has been designed with the use of a models creation module of the metallurgical enterprise information system. The models creation module supports the simulation model creation and multi agent simulation. Agents in the developed model are intended to describe the cutting slabs algorithm used by technologists in the metallurgical production. As a result of experiments with the model the following solution has been found. The following sequence of melts should be supplied to the continuous casting machine: initially the melts from the usual quality steel, followed the melts from the high quality steel.

Development of simulation model of continuous casting machine with dry change of steel ladles

“…Algorithm for cutting slabs on the border of two melts without dry change of steel ladles is given in [6]. This algorithm is expanded by situations presented in Table 1.…”

“…The main stages of the CCM work are given in [6].At the beginning of the work, a tundish is installed on the CCM, a fuse is introduced into the mold, and the steel ladle is ready for casting into the tundish. After passing the extruded ingot from the mold through the turning zone, the ingot is cut into slabs with a gas-cutting tool.…”

“…Simulation for analysis and optimization of the processes in organizational and technical systems is widely used in practice [1][2][3]. A metallurgical enterprise information system (MEI-system) developed by "I-Teсo" JSC jointly with the Ural Federal University includes a data collection and analysis subsystem and modeling subsystem containing modules for creating processes models, processes optimization, data preparation, and models integration [4][5][6]. The models integration module solves the problem of applying models in real-time control and decision making processes [6].…”
