FIELD: mechanical engineering. SUBSTANCE: during corrugated and cell type panels production panels are clamped on a lodgement and are heated as a set up to the temperature, that exceeds minimum temperature of recrystallization of panels material. Then upper surface of a panel is cooled to room temperature. Required radius of curvature is obtained by changing temperature and speed of cooling and ratio of the lodgement and the panel masses. EFFECT: method is used for billets bending. 2 cl, 4 dwg, 1 tbl
