  • What s Cold Finished Steel Bar Product

    Jun 07 2016 · One can easily recognize the difference in finish when comparing a cold finished bar to a hot rolled bar. A hot rolled bar comes out of the mill with a rough abrasive discolored and dirty surface. This is because the steel at the mill is finished at temperatures upwards of 1600° F to 2200° F and at these high temperatures an iron scale

    Oct 08 2014 · Typical reduction of hot rolled strip in cold rolling mill can range from 50 to 90 . The reduction in each stand or pass is to be distributed uniformly without falling much below the maximum reduction for each pass. Normally the lowest percentage reduction is taken in the last pass to permit better control of flatness gauge and surface finish.
