Abstract

Improvements in the manufacture of a composite plate for closing the outlet orifice of metallurgical containers containing liquid laundry, characterized by having preferential application in crucibles having a sliding surface, through hole, supporting surface surrounding the through hole, using the medium of the pressing and calcining of a mixture with a large proportion of granulated and sintered refractory material, providing a mixture of finer grain at least in places with a risk of fissures in the area of the spring and in the support surface. Of the refractory material in the mold showing. (Machine-translation by Google Translate, not legally binding)
