Abstract
A method of constructing a refractory brick lining on a bottom tuyere plate for a vessel for refining or otherwise treating a metal melt comprises the improvement of constructing the lining in an imperforate manner on the bottom tuyere plate and then drilling tuyere ducts in the lining. The brick lining is preferably constructed with the bottom tuyere plate in an upright position and the ducts are then drilled while the plate and the lining are still upright. The bottom tuyere plate is preferably mounted in an assembly frame which is itself pivotally mounted to enable the frame together with the bottom tuyere plate to be swung from a horizontal position to the upright position.
