COLD ROLLED COLD INTRODUCTION
CRC: Cold rolled coils products are produced by most of the top manufacturer in the Europe, Asia, South America with the thickness up to 14mm and the width up to 2000mm. HRC is provided in a range of product specifications, ranging from drawing to structural to meet our customers’ specific requirements
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.
