Abstract

PURPOSE:To uniformalize the temperature distribution of the flange and web and thus to prevent the bending of the angle steel, by cooling the web and flange respectively from the both side of surface and back and, at the same time, by increasing the cooling times for the flange after the angle steel of unequal sides and unequal thickness has been produced rolling.
