What is the process of cold drawing

Hot rolled steel tube continuous casting billet or prerolled billet as raw material, through the stepper furnace heating, high pressure water descaling after entering the roughing mill, rough rolling material through the head, tail, and then into the finishing mill, the implementation of computer-controlled rolling, after the final rolling after laminar cooling and coiler coiling, into straight coil. The head of straight hair coil, tail often shows tongue shape and fishtail shape, thickness, width accuracy is poorer, edge often exists wave shape, fold edge, tower form wait for blemish.

Its coil weight is relatively heavy, and the inner diameter of the steel coil is 760mm. The straight hair coil through the head, the tail, the edge, and the multi-pass straightening, leveling and other finishing line treatment, then cut plate or rewinding, that is a hot rolled steel plate, flat hot-rolled steel coil, longitudinal cut belt, and other products. Hot - rolled finishing coils will become hot - rolled pickling coils if they are pickling, rinsing and oiled. This product has the tendency of partial substitution of cold rolled sheet, seamless steel pipe price moderate, popular with the majority of users.
