摘要

A new simulation model for the analysis of solid to liquid phase transition behaviors inside the blast furnace was developed in this study. The solid state is treated by ADEM (Advanced Distinct Element Method) and the liquid state is treated by SPH (Smoothed particle Hydrodynamics). The intermediate state is treated by overlapped calculation of both ADEM and SPH. Numerical examinations for the analysis of several phenomena such as dam brake flow, droplet deformation due to the contact angle and phase transition were performed. The validity of the proposed model was confirmed by comparison with the experimental results of the motion of the leading edge in collapse of a water column in the dam break test. The phase transition behavior of ore was observed experimentally using horizontal furnace. The deformation started at about 1200°C from the upper corner of sample pellet became round, and melted down to the whole with slight contraction. A similar behavior is also can be seen in the simulation by appropriately setting the relationship between the temperature and the joint spring coefficient. These results are indicated that the developed model has possibility to clarify the burdens behavior including the phase transition inside the blast furnace.
