Product Description:

In the production of steel products, steel is molded and reshaped with different machinery at different temperatures. One process is steel rolling, which involves metal stock passing through a pair of rolls. Rolling produces flat steel sheets of a specific thickness, and the process is classified according to the temperature at which the metal is rolled. If the temperature of the metal is above its recrystallization temperature, or the temperature at which the grain structure of the metal can be altered, then the process is termed as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is termed as cold rolling.

Like cold rolling, cold drawing is performed at room temperature, but instead of producing a flat object like a coke can, cold drawing makes steel into the form of a wire like the spokes of a wheel or a paper clip. To start the process, Steel is usual hammered and rolled so that it can be fit through a die; a tool that turns the steel mass into a wire. The room temperature steel is pulled through the die which reshapes it into a thinner shape while maintaining the same volume. It is similar to the idea of syrup flowing out of a bottle through a tube in that it changes shape but not volume, but instead of squeezing the metal, it is pulled out. In order to get the wire down to the right diameter, it usually requires more than one pass through different dies.
