Abstract

1. A temper rolling process for producing mild steel strips intended for the manufacture of packaging, in which coiled metal sheets are brought substantially to the strip thickness by a first cold rolling, annealing to eliminate structural anisotrophies generated by the first rolling, an then tempering by a second rolling with only slight elongation so as to bring the strip metal to a selected hardness, characterised in that for imparting to the strips which have been box-annealed a hardness comparable to that of strips which have been subjected to continuous annealing and tempered by dry rolling with an elongation of less than 2%, the steel strips, which were of normal quality for continuous annealing, but which have been box-annealed, are conveyed to two successive stands (11, 12), so that the resulting elongation is regulated to a selected value between 4 and 20% and produced for the most part by the first stand (11), the strip is lubricated at the entrance of the first stand by projection (6) of an oil-in-water emulsion, the strip is washed with water (7) at a temperature above the ambient temperature between the stands (11, 12), and the strip is dried by air-blasting (8) at the exit from the second stand (12).
