What is a Slitting Line?
A steel coil slitting line, often referred to as a slitting line or sheet cutting line, is a metal processing line that cuts wide coils of steel into narrower or shorter strips. Although called steel coil slitting line, such a processing slitting line is sometimes used to process sheet metal coils other than steel, and stainless steel is one of the most common materials processed on a slitting line.
The steel coil slitting line uses a composite control table machine, and the steel coil that is flattened and fed into the slitter is called the main coil, and the metal strip produced by the slitter is called "mults", and "mults" are available in various sizes. The length and width of the metal strip can be changed by adjusting the knife pairs and cutters on the slitter.
Meaning of mults: narrow strips of metal formed by slitting or shearing a coil into any width or set of widths that can be fed into a tube rolling mill, roll forming machine or press.
Depending on the material, the workload and the application of the slitting line, a steel coil slitting line may contain machines arranged in several stations by an automatic control system or it may be a simple slitting machine.
For a simple manually operated slitter, the entire slitting operation is done on the workbench. A heavy-duty slitting line for mass production has an decoiler, coil feeder, slitter machine, recoiler and other guiding attachments on the line.

Decoiler and Coil Feeder
Decoiler it usually works together with coil feeder. The decoiler decoils the sheet metal from the coil carriage and feeds it to the coil feeder. The coil feeder is designed to flatten the coil and ensure that the steel sheets are fed evenly into the slitter. In some lines, the uncoiler and feeder are integrated into one machine.
Sheet Slitter Machine
The sheet slitter is an important part of the steel coil slitting line that performs the actual slitting task. The structure of the slitter includes rolls, slideways, gauge adjustment, and knife pairs. Most slitting machines use rollers to cut the sheet.
The sheet slitter is critical in a steel coil slitting line, not only because it slits the rolls, but also because it controls the accuracy of the quality of the result. Tolerances for blade clearance and adjustment should be checked in advance before each production run.
Recoiler
The recoiler collects and recoils the mults at the end of the steel coil slitting line. The recoiler should be set up in synchronization with the sheet slitter machine to allow the winder to better collect the slit steel coils.
This is the quality steel coil slitting line and the process of the steel coil slitting line.
