Abstract��Aiming at the low production efficiency and yield of domestic bulb-flat steel and L-shape steel��relatively technology about bulb-flat steel and L-shape steel of selection, and arrangement of the production line equipment, uneven cooling of rolled piece section, preflex of cooling bed were systematical analyzed. To effectively solve the issues of producing long-sized bulb-flat steel and L-shape steel, some measures were put forward: replacing walking-beam furnace by pusher-type furnace ,installing the frame of horizontal continuous mill in the form of BD1+BD2+3, installing spray nozzles to have inside surface forced cooling after finishing rolling,and adding the function of preflex to cooling bed.
