Abstract
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.degree. C. upon solidification, induction heating of the product and a further step of hot rolling, above point Ar.sub.3, a step of cooling and temperature control in a range of between 600.degree. and 250.degree. C., thus lower than said point Ar.sub.3, 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.
