MODIFICATION AND VERIFICATION OF ACCRETION SIMILARITY CONVERSION METHOD FOR PYROMETALLURGICAL GAS BOTTOM-BLOWING PROCESS

摘要：

In this study, a wax model with an extra low temperature (-110℃) gas blown-in system was established to simulate the phenomena inside ironmaking and steelmaking 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. In addition, Accretion Similarity Conversion Method (ASCM) was developed and for correlating conditions of the accretion formation in the similar systems. A cone- shaped accretion which was modified from a cylinder was applied to correlate the variables in the system. The results indicate that the size of solid accretion inside the wax model can be reasonably estimated by ASCM.
