Manufacturing Process

Hot rolled steel is cleaned by washing with hydrochloric acid on a push-pull pickling Line. It is then passed through a 4-HI Reversing Mill where the thickness is reduced; the coil is then forwarded for rewinding before being annealed in a controlled atmosphere of hydrogen. Once removed from the annealing cycle the coil is transferred to a skin passed mill where a final reduction take place and oil is applied through an electrostatic process. Before packing the CRC material is sent to a tension leveler where it is processed to ensure surface flatness.

CRC material can also be further processed as per customer requirement on our slitting and cut to length lines if specific coils strips or sheets are required.
