Abstract

A system of equations was obtained using mathematical modeling to predict the temperature of oily scale packed in a metal container as it moves from the furnace throat to the hearth. Characteristics of scale packed in a metal container: iron content 69.5%; heat capacity 681-1246 J/(kg∙°C) depending on the content of water and oil in the scale in the temperature range of 100–1500°С; bulk density of scale placed in a metal container 2089 kg/m3; radius of the metal container – 0.041 m. For the conditions of its loading into the ore crest zone of the furnace throat with a volume of 1370 m3, it was determined that oil will begin to evaporate from the metal container at a distance of 88% of its working height and will continue to the level of 77%.
