PCT No. PCT/IT91/00057 Sec. 371 Date Jan. 8, 1993 Sec. 102(e) Date Jan. 8, 1993 PCT Filed Jul. 5, 1991 PCT Pub. No. WO92/00815 PCT Pub. Date Jan. 23, 1992.A process for obtaining steel strip coils with characteristics of a cold-rolled product, directly in a hot-rolling line, comprises subsequently to steps of casting and thickness reduction at a temperature of more than 1100 DEG C. upon solidification, induction heating of the product and a further step of hot rolling, above point Ar3, a step of cooling and temperature control in a range of between 600 DEG and 250 DEG C., thus lower than said point Ar3, as well as one or more passes of cold-rolling in series, with final coiling of the obtained product. Also a preferred plant is described for putting into practice such a process.
