Abstract

Steel mills the whole world over seek to put into operation the process of continuous casting integrated with rolling, in view of the possible significant cost reductions that this would bring about, notably due to the great reduction in energy consumed. This integration would also provide for a marked improvement in the quality of the products, in view of the reduction in the stages of the process: the reheating of the plate would be eliminated. In addition to the construction of new micro-mills, it is known that the market shows the possibility of some integrated mills incorporating a thin plate rolling machine next to the LD converter. At the moment, the process of the continuous casting of thin plate is the most accepted solution amongst the Near-Net-Shaping Casting processes. One of the advantages of the continuous casting of thin plate is the possibility of coupling together the continuous casting and the rolling. With the integration of this unit with an electric steel works or an LD, both capital investment and operating costs can be reduced, resulting in high productivity and shorter times for order completion. The main argument in favor of the productivity of this type of plant is savings achieved. (AU)
