Abstract: A vessel, for example a metallurgical tundish for multi-strand casting, has at least one discharge assembly/block. Such assembly includes a refractory perforated brick fitted in the vessel, the perforated brick having therethrough an opening that is at least partially defined by a surface that is rotationally symmetrical about a longitudinal center axis of the opening. A refractory nozzle brick has a peripheral surface that is rotationally symmetrical about a longitudinal center axis of the nozzle brick. The nozzle brick has therethrough a discharge opening that is located eccentrically of the longitudinal center axis of the nozzle brick. The nozzle brick fits into the opening in the perforated brick with the longitudinal center axes thereof coincident, such that the nozzle brick is rotatable relative to the perforated brick about a rotation axis that is defined by the coincident longitudinal center axes.

Abstract: A refractory channel connection apparatus transfers molten metal from a metallurgical vessel into a mold of a continuous casting machine formed by a peripheral groove and a casting wheel and a band covering the open side of the groove. The channel connection apparatus includes a refractory pouring tube having an inlet end connected to the discharge nozzle of the metallurgical vessel, an outlet end and a molten metal passage extending from the inlet end to the outlet end. A refractory nozzle extension is provided at the outlet end of the pouring tube, the nozzle extension having therethrough a flow through passage communicating with the passage of the pouring tube, an outer profile dimensioned to extend tangentially into the mold and to define therewith a gas seal slot, and a lower end extending into the mold to a level above the upper level of metal cast therein.
