Abstract
Abstract A refractory component, notably an insert (1) for use in repaired (or prime) fixed or slidable plates in slide gate valves on steelplant vessels. The insert, which is preferably a pre-formed moulding, may be a flat plate of generally elliptical form having a circular bore therethrough or it may be T-shaped in side elevation comprising a parallel faced elongated head of elliptical form and a stem of circular section, the circular bore extending through the component co-axial with the stem.

Independent Claim
29 words
A refractory component for use in equipment in metal melt-holding vessels, characterised in that it comprises an insert of generally elliptical form (1) having a circular bore (3) therethrough.
Claim 2
Dependent Claim
29 words
A refractory component for use in equipment in metal melt-holding vessels, characterised in that it comprises an insert of generally elliptical form (1) having a circular bore (3) therethrough.
Claim 3
Dependent Claim
42 words
A component according to claim 1, characterised in that the insert is T-shaped in side elevation, comprising a parallel-faced elongated head of elliptical form and a stem (2) of circular section, the circular bore extending through the component co-axial with the stem.
Claim 4
Dependent Claim
