Decoiling

Decoiling is the process of unwinding and cutting the steel coil to length. The coil material is placed on the coil cart of the un-coiler to load into the rotating shaft where it is uncoiled. The coil loop is controlled by two photocells and ultrasonic sensor.

Levelling

As the loop is loosened up from the parent coil it goes through a leveling machine that flexes the steel through a bunch of rollers so as to extend the material past its yield point to reset the stresses caused during its manufacturing at the steel mill. The measures used to make sheet metal at the plant produce a sheet with caught stresses, a virtual back-and-forth of tug and war. A sheet turns out to be level when those forces are at a balance across all directions of the plate To accomplish this balance, coil processors can utilize different restorative leveling methods tension levelling, temper pass levelling etc yet roller levelling stays the dominant used tech.
