PROCEDURE AND INSTALLATION FOR PROJECTING A MULTILAYER INSULATION AND REFRACTORY COATING AND COATINGS SO OBTAINED.

摘要

The process makes it possible to apply an insulating refractory coating consisting of at least two layers of the same or different thickness, of different composition and of the same or different water content on surfaces such as the inside of metallurgical receptacles (1), and at least two aqueous, pasty and hardenable products are applied successively to the surfaces. …??For each layer of different material, the corresponding products, pulverulent and/or fibrous, feed successively, in a continuous or discontinuous manner, one and the same means (10) of projection onto the surface to be coated. …??Use for coating continuously the inside of metallurgical receptacles. …IMAGE…
