PROCESS AND PRODUCTION LINE FOR MANUFACTURING HOT ULTRATHIN STEEL STRIPS WITH TWO CASTING LINES FOR A SINGLE ENDLESS ROLLING LINE

摘要

A production line for hot steel strips, being fed from two casting lines (a, b) for thin slabs of thickness ≤ 100 mm, only one of which (a) is aligned with a finishing rolling mill (g), comprises also two pairs of rotatable heating furnaces with mandrel (Al, A2; Bl, B2), each respectively on either line, with an intermediate bypass section (d) between the furnaces of the first pair (Al, A2) to allow the endless rolling in a finishing rolling mill (g) located downstream. The furnaces (Bl, B2) of the second pair of furnaces on the line (b) can be transferred along a path (k) from said line to the rolling line and vice versa for producing single strips. Furthermore an induction furnace (f) is provided upstream of the finishing rolling mill (g). Also the corresponding production process is described.
