slabs are taken to slab warehouse from the continuous casting or initial rolling mill. EN 10155 S355J2WP corrosion-resistant steel plate slabs are removed by the crane and stored in the warehouse. The EN 10155 S355J2WP corrosion-resistant steel plate slabs are hanged by crane to the track one by one, and then transported to the furnace for heating. There are continuous heating furnace and flat-type furnace. The well heated slabs are delivered to the vertical scale machine by output rail, and the first oxide scale is removed. Then EN 10155 S355J2WP corrosion-resistant steel plate slabs enter the first, second two-rolls roughing mill, rolling back and forth three or five times, and then into the thirdth and fourth four-roll roughing mill for continuous rolling.
