The evolution of microstructure in hot rolling of aluminium alloys depends on the interaction of the main process parameters: temperature, strain, strain rate and inter-stand time (Hirsch, 2006a, 2006b)The hot strip geometry and microstructure also affects the final sheet geometry and properties, also after final cold rolling, so special attention must be paid to the hot mill process .
A typical rolling mill consists of a pair of rolls driven by an , Pictures showing the rolling process: Equipment – Picture 3 10 , Hot rollingis a rolling operation carried out at a temperature just below the metal melting point, permitting large amount of deformation
Hot rolling is necessary for harder items, like metal, in order to make it possible to roll the item While the exact temperature and certain specifics can vary from one hot rolling process to another, it generally is going to utilize the same basic procedure

SMS DEMAG Hot Strip Mills 8 The coilbox arranged between the roughing stand and the finishing mill of a hot rolling mill forms coils of transfer bars, thus serving as both material and heat accumulator During uncoiling, the former trans-fer bar tail runs into the finishing mill as transfer bar head The coilbox is employed in new facilities .
Thanks to integrated process models today's demands for flexible and economic production of steel plate can only be met by electrical and automation solutions based on technological process modeling, high-performance control systems, and a comprehensive understanding of hot rolling technology
accuracy in thickness control in metal rolling area If the required accuracy of hot rolling mills can be achieved, then in some cases, cold rolling is not even required, which can result in a radical decrease of production costs The schematic structure of a typical aluminum hot reversing rolling mill ,
Mar 27, 2014· Rolling can be done either by hot rolling or by cold rolling Cold rolling usually follows the hot rolling During hot rolling of steels, the cast grain structure of steel achieved during the steelmaking process (usually large grains grown in the direction of solidification) is converted into a wrought grain steel structure
This mill process involves rolling and reducing steel at a high temperature to achieve the required thickness Our product range provides essential temperature measurements at key process points, in hostile conditions

A full-day parallel session will be devoted to discrete plate and Steckel rolling, and tours will be offered of sheet and plate rolling operations Who Should Attend Anyone who would like to expand his or her knowledge and understanding of hot strip mills, Steckel mills, plate mills and hot rolling
In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation The place where all the equipment for metal rolling manufacture is set up is called a rolling mill Rolling mills often vary in ,
Steel Forming Process 1 – Hot Rolled Steel Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel’s recrystallization temperature When steel material is above the recrystallization temperature, it can be shaped and formed easily, and the .
