Beschreibung
Zusammenfassung:	A method for lining hollow metal article includes heating article to temperature 500-700 DEGREE C, filling inner cavity with melt of silicate material, soaking melt till formation of lining layer, following discharge of silicate material melt rest and cooling article to temperature of environment. Before heating article one applies protective layer to its inner surface. At formation of lining layer, to inner cavity of article one adds in portions fresh melt of silicate material. Cooling of article is performed in several stages with soaking at each stage. Cooling and soaking of article is performed with temperature difference between metal body and inner surface of laying layer that is allowed not larger than 50-60 DEGREE C. Aluminium or calcium oxides are applied to inner surface of article as protective layer.
