Abstract
The flux-cored wires and technologies of arc surfacing of steel hot mill rolls were developed. The results of investigations and practical experience allows recommending the developed flux-cored wires for surfacing of steel rolls of the following mills: for roughing (blooming and slab) - PP-Np-25Kh5MSGF; for continuous billet - PP-AN147, PP-Np-35V9Kh3GSF; for heavy-section and rail-beam - PP-Np-25Kh5MSGF; for medium- and light-section - PP-Np-25Kh5MSGF, PP-AN147, PP-AN204; for wire - PP-Np-35V9Kh3GSF, PP-AN132; for sheet - PP-AN132, PP-Np-25Kh5MSGF; for pipe ones - PP-AN147, PP-Np-35V9Kh3GSF. 3 Ref., 1 Table, 1 Figure.
