Title:
METHOD AND PLANT FOR PRODUCING A METAL STRIP
Document Type and Number:
WIPO Patent Application WO/2013/110754
Kind Code:
A3
Abstract:
The invention relates to a method for producing a metal strip (1) in a plant, comprising a continuous casting installation (2), a first furnace (3), a second furnace (4) and an adjoining rolling mill (5). To save energy, according to the invention the method provides the following steps: a) setting a production level of metal slabs or metal strips (1) to be produced, comprising at least two different metal slabs or metal strips (1); b) determining the respective entry temperatures (TFM) into the rolling mill (5) for all the metal slabs or metal strips (1) to be produced; c) determining an exit temperature (TAO1) from the first furnace (3), wherein this temperature is chosen to be lower than the highest entry temperature (TFM) into the rolling mill (5) determined in step b) and is chosen to be lower than or substantially the same as the lowest entry temperature (TFM) into the rolling mill (5) determined in step b); d) operating the first furnace (3) in such a way that the metal slabs or metal strips (1) to be produced leave the first furnace (3) with the exit temperature (TAO1) determined according to step c); e) heating or reheating a metal slab to be produced or metal strip (1) to be produced by means of the second furnace (4) to its required entry temperature (TFM) into the rolling mill (5), provided that this temperature lies above the exit temperature (TAO1) of the first furnace (3) that was reached according to step d). The invention also relates to a plant for producing a metal slab or a metal strip.
