Saving Ladle Control Model of Steel Ladle in Steelworks

Abstract:

Nowadays steelworks exists unmatched phenomenon of production rhythm between basic oxygen furnace and continuous caster, which need to saving ladle to ensure the caster casting, therefore the scientific-reasonable saving ladle control model of steel ladle could achieve energy saving significance. Based on the steel ladles of H steelworks as the research object, this article analyzes its operation process and time, matching model of basic oxygen furnace and caster. Through analyzing the relationship between the time of saving ladle and heats, the control model of saving ladle is constructed, which could calculate the reasonable time value of saving ladle, full ladle operation time and turnover cycle. Through applying Gantt chart to analysis and study the turnover rule of steel ladle, the turnover number control model of steel ladle is constructed. Satisfactory effects were obtained after applying the control model in production: saving number and turnover number were reduced, turnover ratio was increased, temperature drop was reduced.
