Abstract

1425752 Annealing coils of strip NIPPON STEEL CORP 25 June 1973 [23 June 1972] 30142/73 Heading C7N A coil of steel strip is so formed that at least one end of the coil has one or more projections upon which the coil stands on the base-plate of an annealing furnace. The projections may be produced by alternately moving the strip to left and right during coiling, or by notching or otherwise shaping the edge of the strip.
