Abstract
A refractory nozzle comprises a substantially tubular portion with an axial through bore and a plate comprising a first, contact surface normal to the axial through bore and comprising the outlet opening, and a second surface opposite to the first contact surface joining the wall of the tubular portion to the side edges defining the perimeter and thickness of the plate. All but the first contact surface of the inner nozzle plate are at least partially clad with a metal casing having side edges. The inner nozzle plate metal casing comprises three separate bearing elements jutting out of the side edges. Each bearing element comprises a bearing ledge facing in the direction of the contact surface and distributed around the perimeter of the plate. The centroids of the orthogonal projections onto a plane parallel to the contact surface of the bearing ledges form the vertices of a triangle.
