SLIDE GATE OF FOUNDRY LADLE Russian patent published in 1998 - IPC

FIELD: ferrous metallurgy; may be used in casting of steel and other liquid metals with provision of uniform distribution of forces of pressing the refractory plates to each other over their surfaces. SUBSTANCE: slide gate has mounting frame, carriage, fixed and movable refractory plates with holes pressed to each other by means of spring blocks. Secured to mounting frame are six posts symmetrically arranged with respect to slide gate longitudinal axis. Axes of two central posts rest in the same plane with axis of holes of fixed refractory plate. Slide gate is provided with the balance beams, each having central hole and forms together with respective central post, cylindrical kinematic pair with two degrees of freedom. Balance beam arms come in contact with one end of spring block. The other end contacts the supporting rod having longitudinal flat and running through holes of extreme posts located on both sides of respective balance beam. Located on balance beam arms, on both sides of longitudinal axis, in pairs, are axles of supporting rollers coming in contact with guide projections of carriage for coming off them. EFFECT: uniform distribution of forces pressing refractory plates to each other. 2 cl, 8 dwg
