PERFECCIONAMIENTOS EN UN LADRILLO REFRACTARIO

摘要

Sliding discharge gates for liquid metal containers have two apertured refractory plates in contact with one another and which slide one relative to the other to open and close the gate. In order to improve the support and fixing of the plates in the gate, at least one of the plates 20 has a sheet metal covering in the form of a shell 10 which covers only one face of the plate 20 and at least part of the sides 24 of the plate 20, the shell 10 having an aperture 12 which is at least as large as the aperture 21 in the plate 20.
