STEEL SCRAP PRE-HEATING DEVICE AND METALLURGICAL MELTING VESSEL FITTED WITH IT

摘要

FIELD: metallurgy.SUBSTANCE: invention relates to metallurgy and can be used for pre-heating of the steel scrap to be loaded into the metallurgical melting ladle. The device contains the vertical shaft surrounded with a housing wall for reception of steel scrap and at least one, comprising several pins passing in parallel to each other, located in the side direction at the distance from each other, the closing element installed movably between the closing position and the opening position, the pins which in the closing position at least partially penetrate into the shaft for retention of steel scrap and in the opening position release the shaft so that steel scrap drops out of the shaft into the melting ladle.EFFECT: invention provides shorter time of scrap heating process.20 cl, 4 dwg
