Definitions
- the invention relates to a method for rolling pre-strips cast on a strip caster in a hot wide strip finishing rolling mill, the cast pre-strip being brought to rolling temperature in a continuous operation and introduced into the finishing rolling line for rolling out.
- the invention also relates to a plant for carrying out the method.
- a method and a system for producing hot-rolled steel strip from cast pre-strip is known, the cast pre-strip being brought to a homogeneous hot rolling temperature after solidification in a roller hearth furnace and introduced into a multi-stand finishing rolling mill for rolling out to finished strip, which is followed by a cooling section and a coiler is.
- This technology shortens the production chain from raw steel to coiled hot strip and creates the possibility of cost-effective production of high-quality strips.
- the invention aims to further improve the economy of the generic method and the degree of utilization of the system.
- the object of the invention is in particular the expansion of the production program of a production unit consisting of a steel strip caster and a finishing mill. Furthermore In the event of a malfunction in the finishing mill or in the coiler, a break in production or the occurrence of scrap should be avoided.
- the solution to the problem is, according to the invention, that cast pre-strip is rolled in the finishing mill as an alternative to hot strip rolling to heavy plate thickness and then cooled, cross-divided and stacked.
- the heavy plate rolling in the finishing mill can be carried out with a reduced number of passes, preferably three or two passes, compared to the number of roll stands.
- a production unit consisting of a strip caster, a furnace, a finishing mill, a cooling section and a reel device is provided with a cross-cutting shear and a stacking device to carry out the method following the reel device.
- a safety device for strip tips not covered by the reel is advantageously arranged above a roller table, which can be swung up over the passage area of the roller table in the case of heavy plate salting.
- a steel strip casting system 1 is followed by a cross-section device 2, with which the cast pre-strip is divided into pre-strip lengths 3.
- the pre-strip lengths 3 are temporarily stored in a roller hearth furnace 4 and brought to a homogeneous hot rolling temperature of 1050 to 1100 ° C. Thereafter, the pre-strip lengths 3 are scooped by scissors 5, descaled in a descaling device 6 and rolled in a finishing mill 7 consisting of four stands.
- the rolled steel strip passes through a cooling section 8 behind the finishing mill 7.
- Rolled hot wide strip is wound into coils in a reel 9 after cooling.
- the reel 9 is followed by a swiveling catch device 10.
- the pre-strip lengths 3 can alternatively be rolled to heavy plate thickness if necessary or in the event of a fault. This can also be done with a reduced number of stitches.
- the rolled heavy plate strip is cooled in the cooling section 8 and, after swiveling up the catching device 10, overruns the reel 9 on a roller table 19.
- the heavy plate strip is cut into heavy plates 12 by a pair of scissors 11, which are conveyed by a driving device 13 into a height-adjustable stacker 14 before an advance 15.
- the stacker 14 is provided with driven rollers 16, on which the stack 17 is conveyed onto a discharge roller table 18.
