Corrosionpedia - What is Hot Rolling? - …

Hot rolling is a metalworking process in which metal is heated above the recrystallization temperature to plastically deform it in the working or rolling operation. This process is used to create shapes with the desired geometrical dimensions and material properties while maintaining the same volume of metal.

Continuous casting - Wikipedia

Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots.Since then, "continuous casting" has evolved to achieve improved yield, quality ...

Hot & Cold Working and the Rolling Process

In cold rolling, the metal piece is not heated immediately prior to rolling but the temperature of the workpiece will rise due to the frictional effects of rolling. Steels that are cold rolled become work hardened and annealing is required in order to obtain the desired hardness. The difference between hot rolled and cold rolled steels is the mechanical and chemical properties of the end products.

Drawing (manufacturing) - Wikipedia

Drawing differs from rolling in that the pressure of drawing is not transmitted through the turning action of the mill but instead depends on force applied locally near the area of compression. This means the amount of possible drawing force is limited by the tensile strength of the material, a fact that is particularly evident when drawing thin wires. The starting point of cold drawing is hot ...
