Sažetak

The steel- t eeming time, directly affected by the output parameters of power supply, is one of the most important technical indicators for the electromagnetic steel-teeming system. The location and thickness of the blo cki ng layer in the mol ten steel c hannel directly affect the steel-teeming time. This paper establi shes numerical simulation model and uses hi gh temperature off-line test to prove the accuracy of numerical simulation. Result shows: As the tonnage increase of ladle, the posi tion and thickness of blocking layer are basically unchanged; As the length of molten steel channel extends, the pos iti on of bloc king layer shift upper and thicker; As th e diameter of molten steel channel extends, the blo cking layer is lower and thinner slight; Comparing the molten steel channel in “horn” shape with cylindrical shape, the blocking layer of former is upper and thicker than the latter.
