ABSTRACT:
A refractory pouring spout and channel unit for the arrangement on the outlet of a tundish of a strip casting installation has at least one vertical, refractory pouring spout and channel part (25) which can be connected to the tundish; and a refractory pouring spout and channel part (25′) which originates from said vertical part, which extends horizontally and which is provided with one or more openings that are distributed over its length. This results in almost constant laminar flow conditions for the melt flowing between the casting rollers.
