SLIDE GATE OF FOUNDRY LADLE

摘要

FIELD: ferrous metallurgy; applicable in teeming of liquid metals. SUBSTANCE: the offered slide gate has upper frame with immovable refractory plate, lower frame pressed against the upper frame by spring mechanism. Lower frame has port. Sides of port 9 has cantilevered roller supports over which guide protrusions of carriage move together with movable refractory plate. Refractory plates have drains. Installed on one of frames are shafts carrying eccentrics for interaction with the other frame. Suspended eccentrically from shafts with the help of hinges are indicating rods whose ends are engageable with bottom plate of heat screen-cover. EFFECT: higher operate reliability, increased service life of refractory plates.
