Abstract
The waves formed on bath surface play an important role in the bottom blown copper smelting furnace operations. Simulation experiments have been carried out on model of the bottom blown furnace to investigate features of the waves formed on bath surface. It was found that the ripples, the 1st asymmetric standing wave and the 1st symmetric standing wave were able to occur in this model, and empirical occurrence boundaries have been determined. The amplitude and frequency of the standing waves have been systematically investigated. It was found that the amplitude of the 1st asymmetric standing wave is much greater than the 1st symmetric standing wave and the ripples; and the amplitude is found to increase with increasing bath height and flowrate but decrease with blowing angle. The frequency of the 1st asymmetric standing wave is found increasing with bath height but independent of flowrate and blowing angle.
