Abstract: A device for oscillating ingot moulds in continuous casting plants, the oscillations being in a linear or curvilinear course comprising in reciprocal coordination and cooperationA lever (16) extending laterally to ingot mould (29) and having two arms (18) disposed symmetrically with respect to ingot mould (29);Two vertical uprights (25) positioned laterally to ingot mould (29), and hinged (21) onto arms (18) of lever (16) and both extending upwards to surface (24) supporting the ingot mould and being rigidly fixed to surface (24);Guide surfaces (33) geometrically defined by the course of the ingot mould (29) and secured to the vertical uprights (25);Roller guides (34-35) for each vertical upright (25), anchored to the carrying structure and cooperating with guide surfaces (33), andElastic adjustable traction means (31-32) extending above lever (16) and located laterally to the ingot mould, guide surfaces (33) being anchored near surface (24) supporting the ingot mould and lever (16) being positioned below the

Abstract: The present invention discloses a process of closing a nozzle hole in the bottom of a tundish, which is used in pouring molten steel. The tundish has a bottom, which is generally funnel-shaped and, also, has wall means which define the nozzle hole. The steps of the process comprise placing a closure in the nozzle hole to close the same and then placing a finely divided chrome compound on top of the closure and into the nozzle hole and in an amount to at least partially fill the bottom of the tundish. The chrome compound has a sintering temperature of on the order of at least 1740.degree. C. The closure is provided by inserting a rolled up and pressed asbestos bead into the nozzle hole with an end of the bead extending out of the nozzle hole in a position to be grasped by a workman. The tundish of the present invention is operated by pouring molten steel into the tundish and on top of the finely divided chrome compound, which resides on top of the closure.
