Project Report on COLD ROLLING MILL FOR STAINLESS STEEL (4 ...

In cold rolling, the properties of hot rolled coil products, thickness, mechanical and technological characteristics, are changed by compression between rollers without previous heating of the input. The input is obtained in the form of coils from hot rolling mills. The processing steps and the sequence of processing in a cold rolling mill depend on the quality of the steel treated.

Hot Strip Mill and Cold Rolling Mill | Industry ...

Hot rolling. This process stretches a slab into a strip. The slab is reheated to approximately 1250°C and rolled in hot conditions. The resultant strip steel is wound into a roll like toilet paper (hot coil). Chains for lifting; Toughrollers; Conveyor chains for conveying semifinished products

Cold Rolling of Steels – IspatGuru

 · Cold rolling of pickled hot rolled strip is accomplished by processing steel strip through a rolling mill which has an entry end reel for uncoiling the pickled hot rolled coil and an exit end reel for coiling of the cold rolled strip. In between, there are one or more (normally up to 6 nos.) rolling mill stands for carrying out the cold reduction. Each mill stand has vertically stacked rolls ...

The Differences Between Hot and Cold Rolled Steel ...

 · NOTE: Hotrolling and coldrolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hotrolled or coldrolled. HOTROLLED STEEL. Hotrolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F.

Difference Between Hot and Cold Rolled Steel | Metal ...

 · 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 is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. Hot rolled steel is typically cheaper than cold rolled steel due to ...
