Surfacing of Steel Mill Rolls by Submerged Arc Welding

The techno-economic possibility of rebuilding Steel Mill Rolls by submerged arc welding process is well-known. It has been adopted as a regular practice in U.K., U.S.A., U.S.S.R. and continental countries. Initiative has also been taken by some Steel Plants in India in this respect and welding procedures have been successfully established for a few types of rolls. It is felt, however, that there is considerable scope to enlarge the reclamation activities to cover a wider range of rolls and also in developing the technique for manufacture of "Weld Surfaced" duplex rolls, a relatively new concept in the manufacture of rolls.
