Template for centering rollers at the foot of an ingot mold

Abstract

A template (1) for centering rollers at the foot of an ingot mold, the ingot mold being provided with a round section crystallizer into which the template can be inserted passing therethrough from a first end to a second end, the template comprising a round section tubular frame (5), defining a longitudinal axis (X) and having a plurality of longitudinal slots (6) arranged at an equal angular distance from one another; a plurality of longitudinal plates (7) configured so that each longitudinal plate is inserted into a respective longitudinal slot (6) and can move in radial direction through said respective longitudinal slot; at least one inflatable chamber (8, 8′), housed into the tubular frame (5) and at least partially covering the longitudinal extension of a frame stretch adapted to remain inside the crystallizer when the template is inserted into said crystallizer, said at least one inflatable chamber being adapted to expand so as to move said longitudinal plates outwards in radial direction to adhere them to the inner wall of the crystallizer.
