摘要

duplex (Duplex) steel or super austenitic (Super Austenite) rivers as Roughing after the generation that rolled bars hot-rolling system and method are disclosed for the up-grade to occur at the front end of. Hot rolling system, a rolling mill for producing crude bar rolled to a predetermined thickness by rolling a slab of a given grade of the present invention; Bar heater for heating the bar produced by the rolling mill the tank; Finish rolling mill for producing a strip by rolling the heated rolled bar in the bar heater; Detecting the leading edge and the tank is installed between the rolling mill for detecting the front end of the heater bar of the roll bar shape; Up upward occurrence determination unit configured to determine whether the tip of the rolled bars by analyzing the detected shape by the leading end detector; And is disposed between the rolling mill and the bar heater tank, if it is determined that the front end is called up by the up-judgment unit, the front end of the rolled bar to a predetermined length and a cutter for cutting the front end. ;
