Types of CRNGO
After surface conditioning, the bands are usually cold rolled directly to final gage, and sold to the transformer manufacturer in one of two conditions fully-processed, or semi processed. After final cold rolling, the strip is annealed, decarburizing it to 0.005% C or lower and developing the grain structure needed for the magnetic properties.

Rolling Mills Selection Guide: Types, Features, Applications
Rolling mills are machines that shape metal by passing it through two rolls. They are used to flatten and reduce metal to a sheet or plate. Most rolling mills feature two or more rolls arranged in a symmetrical pattern, with half above the work and half below the work to be rolled. Typically, the rolls are mounted one above the other and rotate ...
