in this study, vanadium recovery from the steelmaking converter slag was studied. salt roasting-basic leaching is the process which was applied to separate and extract vanadium from steel making slag. ground slag was roasted after mixing with determined quantities of sodium carbonate. the effect of time and temperature of roasting and sodium carbonate content were studied. the optimum temperatu...

In this paper, a knowledge-based information system for the plant operation of steel making company has been proposed. The system, which is named as K-VRS(Knowledge-based Virtual Reality System), provides a connection between ERP plant maintenance module and knowledgebased engineering methodologies, and thus, enables network-based highly effective plant maintenance process. The developed system...

This thesis will evaluate the utilization of process management tools in the implementation of a major engineering project in a steel plant of Gerdau Group in the city of Charqueadas, Brazil. The project consisted of an increase in capacity of the electric arc furnace in order to improve the availability of liquid steel to the subsequent processes in the Melt Shop. The evaluation will be perfor...
