PREPARATION OF METALLURGICAL LADLE Russian patent published in 2015 - IPC B22D41/44 

FIELD: process engineering.

SUBSTANCE: invention relates to metal teeming. Tapping channel 2 of ladle 1 is inspected and cleaned. Guide bushing 4 is secured from below to the end surface of the shutter gate manifold barrel end surface 3, bushing opening being located opposite said ladle tapping channel. Initial mix feed tube 5 is fitted through the guide bushing opening into the tapping channel to make the tube end surface extend above the ladle bottom. Said initial mix packed in sealed containers is fed through said tube from below with the help of pusher 10. After destruction of container top section with filling of the tapping channel with initial mix over the tube perimeter, said tube is withdrawn from the tapping channel at holding therein of the pusher with said initial mix. The pusher and guide bushing are dismantled to shutoff the tapping channel by the shutter gate.

EFFECT: accelerated ladle preparation, decreased consumption of initial mix.
