  • Hot Rollingan overview ScienceDirect Topics

    During hot rolling the microstructure and mechanical properties of the material change with its thermomechanical state determined by composition percent reduction strip thickness strip speed and heat transfer. For steels hot rolling is generally conducted at 850–1200 °C in the austenite phase while for aluminum it is conducted at 350–500 °C. Next the band pulling rollers is fed into the winder. With the reel strip is passed in deforming roller device of plastic bending. Then pre-deformed band in the form of an aluminum framework together with a cladding layers enters the plating rolling mill. The rolling speed of 0.01-0.5 m/s the diameter of the work rolls 500-700 mm

    Abstract In a rolling mill for following aluminum strip it is desirable to apply water to the rolls on the entry side of the mill. Water should be kept off the surface of the rolled strip to avoid marking and to this end a moisture extraction device is arranged to collect moisture passing between the upper work roll and its best condition for rolling and the achievement of subsequent properties. The strip from the hot rolling mill is coiled for transport to the cold mill which might be on the same site or elsewhere. Cold mills in a wide range of types and sizes are available some are single stand others 3 stand and some 5 stand (Figures 1301.02.03 and 1301.02.04).

  • Multi-stand hot rolling mill tension and strip temperature

    A typical hot aluminum rolling mill has multiple rolling stands for successively reducing the thickness of a metal strip. Each rolling stand works the strip by compressing the metal strip and by propelling the strip through the stand rollers. Each rolling stand operates at a speed determined by a respective single variable controller. Apr 15 2008 · ABSTRACT. Among the cold rolling parameters the pressure distribution or friction hill within the roll gap is one of the most significant one. Almost all of the previous works in this regard are based on laboratory simulations rather than industrial mill conditions though the situations can be completely different.
