Strip Cold Rolling. Strip cold rolling is a technology for metal sheet and strip rolling below recrystallization temperature. The raw material is usually hotrolled steel strip or plate which is rolled by a cold rolling mill at normal temperature to produce steel profiles. Coldrolled strip steel and steel sheet have advantages, such as smooth ...

Cold working refers to the process of strengthening metal by changing its shape without the use of heat. Subjecting the metal to this mechanical stress causes a permanent change to the metal's crystalline structure, causing an increase in strength. Metal is rolled between two rollers, or drawn through (pushed or pulled) smaller holes.

Slitting is a sheet metal cutting process with circular knives, which is used to split wide coiled sheet metal into narrower widths or for edge trimming of rolled sheet. The slitting process is schematically shown in Figure The slitter knives are mounted on two arbors together with spacers . The spacers determine the width of the cut and ...

The Disadvantages of Cold Rolling. Coldrolled steel can have a few disadvantages. One is that hotrolled steel is harder to manipulate than coldrolled steel. Deforming metal requires steel that is heated above its recrystallization temperature. Seeing as coldrolled steel is compressed at room temperature, it is much more difficult to shape.

Manufacturing Process. A big difference between welded tubing and hollow bar is how the two are made. Tube is made by taking slit coils of a base metal and running it through a tube mill, which is a series of dies that form the slit coil into a tube shape; either round, square, or rectangular for example. Once formed into the desired shape, the ...

The main difference between hot and cold is that the hot rolled is formed at high temperatures. Unlike hot rolled, coldrolled steel is formed at lower temperatures. Hotrolled steel has a rough, scaled surface and is often used in applications because of its material strength. In contrast, cold rolled steel has a smoother surface and is often ...
