Cold Rolled Grain Oriented (CRGO) silicon steel is used extensively in transformers as core material. This material help to save energy and protects environment. This material is a less expensive one and also helps to reduce core frame size. Cost of windings and cost of oil also can be minimized by the usage of this material. CRGO slitting is a process where the initial coil slits into narrow hoops. But chances of deterioration of magnetic properties emerges as a result of this fine slitting. To minimize this, the head portion of the slitter line is properly designed. Eight different stages of slitting operation are pay-off reel, pinch roll, loop, rotary shear, deburring roll, loop, tension device and tension reel. During slitting, cutting blade sharpness has to be set to yield minimum burr at the slit edge.
