Continuous smelting method of blast furnace casthouse

摘要

PROBLEM TO BE SOLVED: To improve the efficiency of refining treatment such as desulfurizing and desiliconizing.;SOLUTION: In the continuous refining method for a blast furnace runner where a refining agent is added to hot metal flowing through a hot metal flow channel 4 in a blast furnace runner, and an impeller 10 is dipped into the hot metal and is rotated, so as to mix the hot metal and the refining agent, thus the hot metal is continuously refined, the width of the impeller 10, the position of a level difference, the height H and gradient of the level difference, an adding place, and a slag removing place are most properly set, and then hot metal is refined.;COPYRIGHT: (C)2008,JPO&INPIT
