The invention relates to a method for the continuous production of steel wire or bar, wherein a first hot-forming is carried out by rolling at a temperature above the recrystallization temperature, and wherein the overall degree of forming during the first hot-forming is at least 60%. Next, the rolled steel is cooled to below the recrystallization temperature, and then a final forming takes place at a temperature in the range of the non-recrystallized austenite. The cooldown is carried out in a manner that inhibits a potential growth of grains in the austenite rolled steel before the final forming. The overall degree of forming during the final forming is at least 30%. Finally, the rolled steel is cooled down to a predetermined heat holding temperature at the Ar<SUB>1</SUB>temperature and left at said temperature for a predetermined heat holding time. |
