The Steckel mill process differs from the traditional rolling by the presence of coiler furnaces in either side of the rolling stand, as illustrated in Fig. 1, which reheat the strips while wounding upon their drums. This process allows the product to reach lengths approximately equal to 600 m [11, 20]. The carbon steel heating produces an ...
