TH39180A3 - Rolling process for metal strips - Google Patents

Abstract

DC60 (27/04/42) This invention involves the rolling process for metal strips (6), in particular the steel strips (6), in a reverse rolling machine (1), which has coils at one flow source. Piece and roll at the end of the flow one piece (4,5) where the metal strip (6) with the thickness of the metal strip (d) is unrolled from the roll at the flow source (4) at the metal strip temperature ( T) above the predetermined preset temperature (T degree), running through the rolling mill, reverse direction (1) where the size is reduced. It is initiated per pass size up to 5% at its output speed (V) and is wound in by winding at the end of the flow (5) with the output speed (v) chosen in such a way that the metal strip. (6) There is a specified constant temperature (T *) when the force is rolled in and where the metal strip (6) is rolled out of the roll at the end of the flow (5) passes through the rewinder. (1) with a reduction of at least 10% of the size per second pass and is coiled by rolls at the source of the flow (4) This invention is particularly concerned with the rolling process for metal strips (6). Especially the steel strip (6) in the rewinder (1), which has coils at one flow source. Piece and curl at the end of one flow (4,5) where the metal strip (6) the tooth is the metal strip thickness (T) above the preset temperature (T degree), running through the rewinder ( 1) which is reduced in size It is initiated per pass size up to 5% at the output speed (V) and is wound in by winding at the end of the flow (5) with the output speed (v) selected. Determined in such a way that the metal strip (6) has a set constant temperature (T *) when energized is wound in and where the metal strip (6) is curled off the roll at the end of the flow (5). Passed through the rewinder (1) with at least 10% reduction in size per second pass and curled by roll at the source of flow (4).

Claims (1)

1. Rolling rolling process for metal strips (6) In particular, the steel strip (6) in the rewinder (1), which has a roll at the source of the flow and a roll at One (4,5) flow tip where the metal strip (6) is the metal strip thickness (d) unrolled from the roll at the flow source (4) at the metal strip temperature (T) above the temperature. Is maintained (T degree), a run through the rewinder (1) with an initial reduction per pass size of not more than 5% at the output speed (V) and is curled in by The roll at the end of the flow (5) where the output velocity (v) is tagged:
