Definitions
- the invention relates to a working method and a system for flexible and economical pickling and cold rolling of metal strips, in particular in small and medium production quantities on a system consisting of metal pickling arranged in a line, a hasp arrangement provided on the winding side of the metal pickling and a cold rolling mill.
- Elimination of the discontinuous threading operation has many advantages and usually result in very high production quantities per unit of time. However, they require such a high investment that many operators of systems for smaller production quantities continue to invest in separate metal pickling and rolling mill systems.
- the object of the present invention is to provide a method and a system with which, without operationally adding or deleting system parts, using with minimal investment and personnel expenditure usual coil sizes and machine dimensions a highly flexible pickling and rolling mill for small and medium-sized production quantities is economically possible.
- Cold rolling mill is introduced and rolled in several forming passes, or c. the strip leaving the metal pickling is wound up as a hot strip on the reel arrangement to form finished strip, or d. Pre-pickled hot strips are fed to the reel arrangement and introduced into the cold rolling mill from the unwinding position and rolled in several forming passes.
- Cold rolling takes place on a reversing rolling mill, into which the strip produced according to work steps a, b or d is inserted and rolled out in several reversing passes is, the tape after one or more reversing stitches is wound on at least one of the reversing reels arranged on both sides of the reversing rolling mill.
- a system for flexible and economical pickling and cold rolling of metal strips according to the work steps provided according to the invention is characterized by a reel arrangement which is designed as a horizontal or vertical reversible reel with two separate drive units for each reel mandrel, which are preferably uncoupled when turning.
- a reel arrangement which is designed as a horizontal or vertical reversible reel with two separate drive units for each reel mandrel, which are preferably uncoupled when turning.
- the reel mandrels of the turning reel are favorably arranged axially displaceably in their housings so that the reel mandrel can unwind the coils wound behind the metal pickling in the center of the rolling mill in a controlled manner.
- the reversing mill can be used as a conventional reversing stand or as
- a system designed according to the invention for carrying out the working process is extremely variable, requires a minimum of operating personnel, requires little space, has low investment costs and shows its greatest economy when using thin hot strip, as is increasingly being produced by thin slab systems or strip casting systems.
- the tape B unwound from a decoiler 1 becomes, after customary preparation, via the drive roller set 2 of the metal pickling 3 designed as thrust pickling
- the metal pickle 3 is equipped on the output side behind the conventional finishing devices 4 such as scrubbers, scrap shears and partial shears with a horizontal reversible reel 5, onto which the strip B leaving the pickle is wound.
- the turning reel 5 has a winding reel mandrel 6 and a decoiler mandrel 7 with separate drives, i.e. each reel mandrel has its own drive unit, which is preferably uncoupled when turning.
- the decoiler mandrel and decoiler mandrel are axially displaceable in the housing so that each decoiler mandrel 7 facing away from the metal pickle 3 can regulate the coils 8 wound behind the metal pickle 3 in the center of the subsequent reversing rolling mill 9.
- the reversing rolling mill 9 consists of a traditional reversing stand, which takes over the coil 8 on the reversing reel 10 after the first reduction stitch.
- the decoiler mandrel 7 of the reversible coiler 5 is then free for exchange with the decoiler mandrel 6 and is again available to the metal pickle 3.
- the reversing stand 9, as shown in the lower half of the drawing, can also be a 2- to 3-stand tandem mill with stands 9a and 9b. These are preferably designed in 6-high construction (the relatively small work rolls are supported via intermediate rolls and backup rolls) for high reductions (over 50% in the first stand), so that part of the pickled strips B are in one
- the metal pickling 3 can be used in the resulting breaks without further so-called non-cold-rolled P.O. Create coils.
- the band B is wound up behind the metal pickle 3 on the winding reel mandrel 6 of the turning reel 5 and released as a finished product.
- P.O. Coils can of course also be pickled during longer breaks in the reversing roll mill 9, for example when changing the backup rolls.
- the flexibility of the system also makes it possible to roll out coils 8 which have previously been pickled in stock in the reversing rolling mill 9 in the event of planned stoppages in the metal pickling 3. These coils 8 are fed to the unwinding reel mandrel 7 of the turning reel 5 and passed there to the reversing mill 9.
