Definitions
- the invention relates to a method for producing steel strip Cold rolling properties according to the preamble of claim 1 as well as a plant for carrying out this process.
- EP 0 541 574 B1 discloses a generic method in which finished strip with cold rolling properties is produced directly in a hot rolling mill from a raw material produced by casting close to the final dimension. It provides that a thin slab strand with a maximum thickness of 100 mm is first produced in a continuous caster, with a rolling device being arranged directly behind the continuous casting mold, on which the casting strand is rolled to the solidification thickness with a liquid and solid core (casting rollers). The thin slab strand is then descaled and hot rolled to a thickness of 10 - 30 mm at temperatures above 1100 ° C on a rolling device with, for example, three stands. The intermediate strip, which is hot-rolled in this way, is divided into partial lengths using band shears.
- the strip-shaped material Before further hot rolling, preferably before coiling, the strip-shaped material is heated again to a hot rolling temperature above 1100 ° C. by inductive heating. The second hot rolling is carried out at a temperature above Ar 3 . Immediately afterwards there is cooling to a temperature below Ar 3 , preferably to a temperature in the range 600-250 ° C. The strip material thus produced is then finish-rolled by cold rolling on one or more stands connected in series and wound into coils.
- the known method aims at the production of cold rolled strip with one as little energy expenditure as possible.
- the methods are used on the one hand casting close to final dimensions (thin slab production) and casting rolling, i.e. the reduction of the thickness of the hot casting strand with a partially still liquid core.
- hot rolling becomes part of that from the continuous casting process remaining heat.
- the disadvantage here is the need, despite the Use of the heat from the continuous casting an inductive heating of the provide band-shaped intermediate product for the second part of hot rolling have to.
- the object of the invention is a method and a system for carrying it out specify in which a separate reheating of the band-shaped Intermediate product and the associated energy and plant costs be avoided.
- the properties should be improved as far as possible of the material produced in the direction of cold rolling properties.
- the present invention only a single contiguous Hot rolling process before, so there is no second hot rolling process and necessary inductive intermediate heating. Instead it is done According to the invention, hot rolling in a single pass, at the end accelerated cooling to a temperature in the range of 850 to 600 ° C. At this temperature is then at least by isothermal rolling three rolling passes, each with a thickness reduction of at least 35% done, the finished steel strip is generated and following this finish rolling accelerated to a temperature of no more than 100 ° C. In contrast, in the known method, the finish rolling takes place at a comparatively significantly lower temperature (approx. 250 to 600 ° C).
- ⁇ T 0 to 20 ° C.
- the method should expediently be operated in such a way that the heat input through a specially introduced deformation work ("speed up") is always above the expected heat loss through radiation and the Temperature control via targeted cooling between the rolling passes is ensured. If namely the actual temperature of the steel strip has fallen below a critical value during the rolling process, it is hardly possible anymore, by changing the rolling parameters Raising to achieve the desired value.
- a melt from a steel preferably from a Deep-drawing steel, filled into an intermediate vessel (tundish) 11.
- the intermediate vessel 11 leaves the molten steel contained in a continuous flow into one below Arranged continuous casting mold 12 flow, which is not shown Has liquid cooling and to form a casting strand consisting of Strand shell and liquid core leads.
- the hot comes Casting strand in a arranged below the continuous casting mold 12 Casting roll device, the casting strand with the partially liquid core in thickness further reduced.
- the thin slab strand 1 occurs with a thickness of 30 to 100 mm, preferably 40 to 70 mm from the casting roll device 13.
- the Thickness reduction in casting rolling is at least 10%. preferably at least 30%.
- the strand then arrives in a descaling device 19 which is preferably designed as a hydromechanical descaling.
- Descaling has the thin slab strand 1 a temperature in the range of 1150 up to 900 ° C.
- the thin slab strand 1 becomes one of the Descaling device 19 immediately downstream hot rolling device 15 supplied, in which a reduction in thickness of the thin slab strand 1 by at least 50 % to an intermediate band of maximum 20 mm, preferably 10 to 20 mm in thickness he follows.
- the expediently two or three stands or else a reversing rolling mill it is normally recommended to switch on a separation unit, e.g. in Form a band scissors 17 around the intermediate band generated in the already mentioned To split part lengths.
- the hot-rolled intermediate strip is according to the invention accelerated cooled down to a temperature in the range of 850 to 600 ° C.
- the each Cooling temperature to be chosen suitably depends on the chemical one Composition of the steel used and according to the target Structure composition and according to the mechanical-technological to be achieved Properties in the finished belt.
- the cooling takes place in a first cooling device 18 instead of the tape shears 17 directly in the diagram shown connected.
- the roll stands are operated so that per Roll pass a reduction in the strip thickness by at least 25%. That the The finished strip leaving the rolling device has a maximum thickness of 2 mm, preferably a thickness of 0.5 to 1.5 mm.
- the rolling device 24 (not shown) cooling devices e.g. in the form of Provide spray cooling that removes excess heat in a controlled manner.
- the actual temperature of the steel strip in the rolling device 24 is by (not shown) Temperature sensors monitored. That emerging from the rolling device 24 Steel strip is accelerated in a second cooling device 25 immediately thereafter cooled down to a temperature of at most 100 ° C.
- the accelerated Cooling is expediently carried out at a cooling rate in the range from 10 to 25 ° C / s.
- the finished strip can be passed through a liquid cooling bath become.
- spray cooling devices can also be used in a manner known per se Course of the roller table with the smallest possible roller spacing of less than 250 mm Find use.
- the finished tape produced in this way should be used Removal can be wound up in the form of coils. There is a for this in the system diagram corresponding winding device 26 is provided.
- Forming intermediate band coils has the advantage that one hand Intermediate material buffer is created, which makes the operation of the Permits rolling devices, and on the other hand the one for maintaining the temperature such a buffer material required compensation furnace 21 only a comparison small area.
- the production route according to the invention leads to a particularly fine-grained one Microstructure formation compared to the result according to the method described in EP 0 541 574 B1 known method is clearly cheaper. It happens in the known method by reheating to 1100 ° C before the second hot rolling into one significant grain coarsening, which in the method according to the invention because of selected temperature range of 850 to 600 ° C is excluded. Another The difference in grain size formation comes from the different Finished rolling. In the method according to the invention takes place during the isothermal rolling, which is at the recrystallization threshold Temperatures occur at the prescribed overall degree of deformation of clearly over 90% another dynamic grain refinement with simultaneous strength and Toughness increase instead.
