DEVICE FOR THE EXPANSION OF METALLURGICAL EXCHANGE

摘要

A device for expanding slag and cinder comprises a channel for carrying molten slag and provided with a lip serving as a spreader to spread out the melt in the form of a thin sheet, the lip being cooled internally; an inclined hollow cooling element constructed in the form of one or more boxes staggered heightwise, and in which cooling water circulates under pressure; nozzles immediately downstream of the lip to feed the cooling water from the cooling element to spray the slag; and a rotating drum which throws the slag into the air before pellets or granules are collected in a sloping collector to remove the non-evaporated water.
