Cold Strip Mill Cold rolled strip steel and sheet steel generally have a thickness of 0.1 - 3 mm and a width of 100 - 2000 mm; All of them take hot rolled strip steel or steel plate as raw materials and are rolled into products by cold rolling mill at normal temperature. Difference Between Hot and Cold Rolled Steel Metal Sep 11, 2014 · 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 steels recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.


For roll cooling applications of hot steel pure water is normally used as a coolant. The water is usually re-circulated in the plant and should have a sufficient filtration grade in order to prevent clogging of the nozzles. The maximum particle size shouldnot exceed 1/3 of the smallest nozzle internal passage. HOT ROLLING PRACTICE An Attempted RecollectionThese rolls can either be flat or grooved (contoured) for the hot rolling of rods or shapes. Under these conditions, the rolls grip the piece of metal and deliver it, reduced in cross-sectional area and therefore, increased in length. x The initial hot-working operation for most steel products is done on the primary roughing mill (blooming

    Temperature Monitoring for Hot Rolling Mills Williamson

    Hot Rolling Mills are used to reheat shapes of steel to soften them enough so that they can be rolled thinner and longer through a series of rolling stands. The finished product can be either a strip, plate, rod, bar, wire, or shape (rails and H-beams). After the steel is formed to its desired shape, it is cooled so that the desired mechanical properties of the steel product are achieved. What is "Cold Rolling" Stainless Steel and Other Metals In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its re-crystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature.

    What is Hot Rolling? - Definition from Corrosionpedia

    Jun 30, 2014 · The hot metal is passed between two rolls to flatten it, lengthen it, reduce the cross-sectional area and obtain a uniform thickness.
