Abstract

Hot rolled wide strips from a continuously cast strand are rolled down in a pitch line, which includes a rolling train. A separate thin slab is cut off from the cast strand in one of two casting lines arranged on the opposite sides of the pitch line, and is homogenized and brought to a predetermined temperature in an equalizing furnace arranged coaxially with a respective casting line. The thin slab is then transported from the equalizing furnace into a movable furnace part formed as an equalizer, a buffer, or a regenerative furnace part and arrange coaxially with the equalizing furnace. The thin slab is then transported from the respective casting line to the pitch line in a direction opposite to the casting direction by pivoting or sidewise displacing the movable furnace part, after a first reverse of the direction of movement of the separate thin slab. The thin slab is transported after a second reversal of a direction of movement from the regenerative furnace to a holding furnace located downstream of the regenerative furnace, and therefrom to the rolling train for obtaining therein and end product.
