This article explores coordinated scheduling problem arising in steelmaking and multi-refining operations. Jobs are first processed in converters and then transported downstream to be processed in refining furnaces in which two different transporters are employed in tandem at the stage of transportation. There exist multi-refining jobs. The objective is to minimize the maximum completion time s...
J. Burja, F. Tehovnik, F. Vode, B. Arh, Institute of Metals and Technology, Ljubljana, Slovenia In this chromium slags that form during melting of chromium alloyed steels are examined. During melting and oxidation of these steel grades a considerable amount of chromium is lost, and gained back with slag reduction. Laboratory experiments were performed to study the mechanism of chromium oxide re...
Companhia Siderúrgica de Tubarão CST, is investing to expand production level in 50%, adding new equipment and altering production process. Simulation is widely used in CST, mainly in strategic phases prior to capital investment. A previous simulation model developed with ARENA was enhanced to help CST achieve new goals: to analyze new process plan with operational details, testing different pr...
The paper deals with solution of logistic problem for converter production of metallurgical enterprises. A developed multiagent simulation model of converter production is applied to solve the problem. This model allows assessing the different variants of the cranes motion between steelmaking aggregates. Three variants of the cranes motion have been considered during experiments with the model....
