Definitions
- the invention relates to a Anwickel Anlagen for a strip reel for metal strip, in particular for cold and hot rolled strips of steel and non-ferrous materials, further designed in particular for pressing a hot rolled magnesium strip with temperatures between 300 0 C and 450 0 C to the band reel.
- the present invention relates to a band reel for winding and / or unwinding of metal strip, in particular for cold and hot rolled strips of steel and non-ferrous materials, further especially for winding and / or unwinding of hot rolled magnesium strip with temperatures between 300 0 C and 450 0 C.
- the present invention relates to a rolling device, in particular for a reversing operation, more particularly for finish rolling a magnesium strip at temperatures of the magnesium strip between 300 0 C and 450 0 C in several rolling passes, with at least one Anwickel bamboo and / or at least one Band reel in each case of the aforementioned type.
- Riemenumschlinger are known as Anwickel Anlagen from the prior art.
- the known Riemenumschlinger are part of a reel device, which is designed to appli-roll rolled sheet on a coiler mandrel to a coil.
- segments of the coiler mandrel can be deflected radially outward such that the outer circumference of the expansion segments forms a circle.
- the coiler mandrel must be smaller in diameter than the inner diameter of the coil to accommodate the coil. For this purpose, two diameters can usually be targeted in a reel mandrel.
- the Riemenumschlinger bring the beginning of an incoming from a rolling metal strip with a coiler drum or a coiler mandrel of a band reel in operative connection, and until so many tape turns are on the reel drum, that a slip-free coiling of the metal strip is ensured without additional contact force.
- the wrap angle of the belt of the belt wrapper In order for the wrap angle of the belt of the belt wrapper to be as safe as possible to ensure that the beginning of the belt into the first belt wrap is as large as possible, the belt is turned around a roller-mounted folding bridge which, after the belt wrapper has moved against the capstan drum, is folded over.
- BE3T ⁇ TlGUNGSKOPrE tallbandes on the reel drum of the belt additionally be brought into operative connection with a belt tensioner.
- the Riemenumschlinger described are due to the limited temperature resistance of the belts used mainly in the cold rolling of metal strips used.
- Magnesium belts can advantageously be produced from cast strip having a material thickness of preferably less than 20 mm by means of cast roll or thin strip casting methods with or without subsequent forming.
- the casting belt solidifies with comparatively high cooling rates and can be wound up into coils.
- the semifinished product is optionally heat treated and then formed, preferably by rolling with or without subsequent roll forming.
- the cast or cast-rolled molding materials are preferably heated rapidly to a suitable for rolling preheating temperature between 150 and 500 0 C.
- the magnesium bands are then manufactured by hot rolling.
- the belt wrappers known from the prior art can not be used or can only be used to a limited extent in hot strip production of, for example, magnesium tapes in order to ensure slip-free unwinding or uncoiling of the hot metal strip. If the metal strip is to be finish-rolled in several rolling passes in a roll stand operated in reversing operation, strong cooling of the metal strip during winding and unwinding should be avoided if possible so as not to impair the forming properties of the metal strip. From the prior art is known in this context to rewind the hot metal strip at least after the first stitch on a warm reel and to keep it at the respective forming temperature. The forming temperature is preferably at least 300 0 C. Keeping warm the tape reel leads to a design overhead and increases the cost of tape production.

Moreover, the heat dissipation from the metal strip is reduced by the insulation in the coiler mandrel, so that there is less cooling of the metal strip during winding and unwinding of the metal strip.
- a heating of the tape reel according to the invention and / or the metal strip after unwinding and before entering the mill stand is preferably not required, but may in principle also be provided.
- the insulation according to the invention can be retrofitted in a simple manner even in otherwise not usable for the winding of hot metal bands tape reels.
