Get PriceRolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot
Get PriceAluminum Rolling Mill Process - Cold Rolling - Hani The constant liquid surface between the furnace and the aluminum rolling mill is very important for the smooth operation of the rolling line. The liquid level is maintained constant by adjusting the outlet flow through a simple flow control device.
Get PriceThe Cold Drawing Process for Steel Bars and Wire Raw Stock: Hot rolled steel bar or rod coils are used as raw material. Because the hot rolled products are produced at elevated temperatures (1700 - 2200 Deg. F. i.e. hot rolling), they generally have a rough and scaled surface and may also exhibit variations in section and size.
