ABSTRACT:
The invention relates to a method for producing a siderurgical product made of carbon steel having a high copper content, according to which: —a liquid steel having the composition: 0.0005%≦1%; 0.5≦Cu≦10%; 0≦Mn≦2%; 0≦Si≦5% 0≦Ti≦0.5%; 0≦Nb≦0.5%; 0≦Ni≦5%; 0≦Al≦2%, the remainder being iron and impurities, is produced;—said liquid steel is poured directly in the form of a thin strip having a thickness of no more than 10 mm;—the strip is subjected to forced cooling and/or is surrounded by a non-oxidizing atmosphere while having a temperature of more than 1000? C.; —said thin strip is hot rolled at a reduction rate of at least 10%, the temperature at the end of the rolling process being such that all of the copper is still in a solid solution in the ferrite and/or austenite matrix;—and the strip is coiled. The invention also relates to a siderurgical product obtained according to said method.
