In this research, a water model with an extra low temperature (−177°C) gas blown-in system was established to simulate the phenomena inside pyrometallurgical vessels for investigating effects of gas bottom blowing conditions on the shape and dimensions of solid accretion sitting on the refractory lining near gas tuyeres.<BR>In addition, Buckingham Pi theorem was adopted to derive the important dimensionless parameters for correlating conditions of accretion formation in the similar systems. Then, by combining dimensionless parameters with heat transfer equations that describe the heat transfer across the accretion, quantitative relations based on the similarity conversion of the similar systems was established. The method mentioned above is called Accretion Similarity Conversion Method (ASCM).<BR>Meanwhile, the experimental work of a wax model was conducted to evaluate the accuracy of ASCM. The results indicate that the size of solid accretion inside the wax model under a specific condition can be reasonably estimated by ASCM.
