PROCESSO DE PRODUCAO DE FOLHAS DE ACO FINAS COM PROCESSABILIDADE APERFEICOADA

摘要

Thin steel sheets having an improved processability are produced when a steel sheet or cast strip obtained through a continuous casting or strip caster process is subjected to a lubrication rolling step at a temperature of from Ar3 transformation point to 300 DEG C. and a rolling speed of not less than 1,500 m/min. By this method, the cold rolling step or cold rolling-annealing step can be omitted.
