Abstract

Abstract

The effective control of slag foaming has an important practical significance for stability of metallurgical process. In this paper high-temperature simulation of slag foaming induced by interior and exterior gas sources had been conducted. Under present experimental conditions, the following conclusions are obtained. Induced by exterior gas source, the foamed slag consisted of polyhedral bubbles with a size of 7～15 mm. The foaming height firstly increased and afterwards decreased with increasing gas flowrate. When induced by interior gas source, the foamed slag was stacked with spherical bubbles with a size of 0.5～1.0 mm; the foaming height increased with increasing gas amount released by slag-metal reaction and decreasing slag basicity. The defoaming agent were classified depending on their effects: active lime > soda ash > limestone > dolomite > magnesite.
