Rolling processes AlMustansiriya University
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 (51) Fig (51) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required Hotrolled metal is generally free of Material temperature on the delivery side of the finisher is an important factor in the mechanical properties of the product coils In order to achieve and maintain the target delivery temperature of the finishing mill, a finisher delivery temperature control system (FDTC) was developed for implementation in a newly built hot strip millApplication of a Temperature Control System to a New Hot R Ganesh Narayanan, IITG Bending: In this, the sheet material is strained by punch to give a bend shape (angle shape) usually in a straight axis Deep (or cup) drawing: In this operation, forming of a flat metal sheet into a hollow or concave shape like a Metal forming processes IIT Guwahati rolled thread (b) Grain flow in machined and rolled threads Unlike machining, which cuts through the grains of the metal, the rolling of threads causes improved strength, because of cold working and favorable grain flow Figure 1315 Threadrolling processes: (a) and (c) Rolling of Metals AdvantagesofAluminum Thepropertiesofaluminummakeitoneofthe mostadvantageousandversatilematerialsin usetodayAluminumis: Lightweight—Aluminumanditsalloys weigh RollingAluminum: FromtheMine ThroughtheMill
