A METHOD FOR REALISING REFRACTORY PLATES, A PLATE RELATIVE THERETO AND A TUNNEL KILN REALISED WITH THE PLATES

摘要

A method for realising prefabricated refractory plates to be used in a tunnel kiln comprising stages of: - mixing powders comprising 10-35% clays, 0.1-35% kaolins, 0.1-80% aluminas, the values being expressed in percentage by weight; - moistening the powder mixture with water up until a powder paste is obtained having a consistency enabling the paste to be extruded; - extruding the paste to form a plate; - drying the extruded plate; - firing the dried plate.
