MELT MOVEMENT IN THE HEARTH FURNACE FOR CHOSEN VARIANT OF GAS BLOWING

Popis výsledku v původním jazyce

The agitation of melt in the hearth furnaces is complicated. It depends on introduced system of technological gases blowing, the shape of working profile of the hearth and a degree of hearth lining wear in the course of furnace campaign. In many cases it is insufficient. The results of experimental study on physical models of hearth furnaces with the considered variants of the blowing system are influenced by incomplete similarity of used physical quantities - dissimilarity in invariants of density and viscosity of melt with the model and the real hearth furnace. That is why it was concerned with the mathematical modelling of agitation effects of selected blowing variant on the movement of melt in the furnace hearth. The results of mathematical modelling of melt movement in the considered variants of blowing may serve not only for the selection of most suitable configuration of blowing system or blowing variant for the given furnace and conditions, but also, among others, to the prediction of erosion effects of flowing melt on the refractory lining of furnace hearth depending upon the gradient of velocity of melt flow in the vicinity of walls of furnace lining.
