How to Produce Steel Plates? The Steel Plates

Jan 01, 2019If thickness below 2.5mm is required, generally coil and sheets are cold rolled to achieve the desired quality, size and thickness. Mild and carbon steel plates are produced by 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.

steel mill

The basic process of working steel is known as hot rolling. Hot rolling is especially applicable to ingots like the one shown above. In hot rolling the cast ingot is first heated to bright-red heat (2300 F) in a furnace called a soaking pit and is then passed between a series of pairs of metal rollers that squeeze it to the desired size and shape.
