PROCEDURE FOR CONTINUOUS COLADA LAMINATION WITH INCREASED COLADA SPEED AND CONSEQUENTIAL HOT LAMINATION OF RELATIVELY SLIM METAL BARS, IN PARTICULAR STEEL MATERIAL, AND CONTINUOUS COLADA LAMINATION DEVICE.

摘要

Process for rolling continuous casting with a casting speed of 4-12 m / min and consecutive hot rolling of metal bars (1), in particular of steel material with a relatively reduced web speed to give a band ( 2) Thin hot rolling on a multi-box hot rolled strip finishing train (3) with temperature control of the working cylinders (4), characterized in that at casting speeds of approximately 4 m / min at 12 m / min and considering casting thicknesses of 20 mm to 90 mm of the casting bar, the rolling speeds are adapted, increasing the temperatures of the working cylinders (4) starting from a reduced initial temperature (5) with a rate of predetermined increase and adjusting the band temperature (15) in the hot rolled strip finishing train (3) at a target lamination temperature (6) of the hot rolled strip (2) and by regulating ion or control of the cooling intensity (18) of cylinder.
