FIELD: metallurgy.
SUBSTANCE: invention relates to controlling melt flowing on chute for melting from regeneration boiler into vessel for solution preparation. Device includes a throttle assembly, equipped with at least throttle valve, and drive to control its position. Portion of throttle valve is made in form of a solid element with an area defined by first side, opposite second side, and its height. Valve can turn between two specified positions, in first of which it does not limit melt flow at least partially, and in second - limits defined region of area of chute for melt.
EFFECT: higher safety and operational characteristics of device.
