Definitions
- the invention relates to a method for producing strips and sheets made of steel according to the preamble of claim 1.
- the invention also relates to a system to carry out the procedure.
- JP-A-57-146403 relates to a hot rolling line for cast products, on the one hand from a conventional continuous caster and secondly from a belt caster come.
- the conventional system is characterized by a roughing stand, that precedes a finishing train.
- this JP-A-146404 introducing the cast products into a ferry a common rolling mill, with the ferry depending on the casting and Rolling plan works
- JP-A-57-149007 discloses steels of relatively low quality by means of strip casting and in a rolling mill together with Higher quality steels made using a conventional continuous caster have been rolled.
- JP-A-57-149008 suggests before that both the products from the conventional continuous caster as well as being fed from the strip caster to a common furnace, in order to then be fed to a rolling mill, the roughing stands and finishing stands includes.
- the present invention is based on the object To further develop methods and a plant that the production of stainless steel strips and sheets is more economical becomes.
- this object is achieved in that, together with the first cast products produced in a first process route at least in a second process route produced second cast products made of stainless steel, when the first cast products are cast from carbon steel, or from Carbon steel when the first cast products are cast from stainless steel, rolled within a common rolling program.
- Essence of the invention is, therefore, products of both types of steel in one plant to integrate in a common rolling mill and within one joint rolling program.
- rolling program is generally the predetermined order of slabs to be rolled in the Understand the period between two roll changes.
- an optimal utilization of a plant is achieved, which at sole production of stainless steel sheets compared to carbon steels would be produced in small quantities, would not be used. moreover becomes a greater variability of a plant on which carbon steels are produced are increased by additional rolling of stainless steels.
- the invention is not based on a rolling program for cast products from the two types of steel limited; It is also conceivable to add other types of steel to roll in a wagering program, but always carbon steels and Stainless steels are rolled together. By the suggestion of rolling in A common rolling program will process two very different types Steel grades regardless of the throughput of a line of plants or possible from the steel production quantity.
- stainless steel is basically defined in EN 10 020. It will be here distinguish between unalloyed and alloyed stainless steels. It is about in the case of the stainless steels according to the invention, for example, roller bearing steels, Tool steels, heat-resistant steels and high-grade structural steels. In particular, are below to define this term higher-alloy steels with alloy elements and - quantities that stabilize the austenite structure at lower temperatures, including the high-alloy austenitic CrNi steels.
- the rolling mill is turned on the material to be processed is adjusted during the rolling program. This means that the rolling mill is already ready for the next one material to be machined from the rolling program is prepared while the previous one is still being edited.
- the negative Effects of the stainless steel rolling on the surfaces of the work rolls which mostly affect rough surfaces and which affect the following Rolling carbon steels have a disruptive effect during operation or already be fixed online.
- the rolling mill is prepared for the respective one Follow-up strip also in the rolling break between the rolling process of two Bands.
- the one with the thin slabs of the first process route in one Rolled second cast products are also available thin slab
- the thin slabs in a second, parallel, process route to the first Process route to be poured and cut are preferred via a second equalization furnace, if applicable, and a ferry into one common equalization furnace and then led into the rolling mill.
- This invention is not based on the described possibility of inclusion of thin slabs
- the integration of any cast product is conceivable, for example produced by strip casting, with precursors produced in this way but already have small initial thicknesses.
- the device proposes a generic system with a Integration unit for introducing at least second cast products Stainless steel when the first cast products from the first carbon steel process line are cast, or for inserting at least second cast products made of carbon steel when the cast products from the first process line are cast from stainless steel, to equip and with a rolling mill for a combined rolling program for cast products made of carbon steel and Stainless steel and preferably with means for preparing the rolling mill for the subsequent rolled product of the other steel grade.
- the rolling mill is a grinding and / or polishing device for the work rolls at least one roll stand provided during the rolling of stainless steel products and / or during the break of rolling a rough roller surface counteract. These are on the inlet side, for example in the form of grinding devices that press against a work roll, preferably arranged on all rolling stands of the rolling mill.
- the WalzStree a flushing device that, in particular or to a greater extent during the rolling of the carbon steel products and / or in the subsequent Rolling break works and the rolling mill from the loose tinder frees the carbon steels.
- claims 8 to 10 are other facilities proposed that provided alone or additionally in the rolling mill are, despite the rolling of two types of steel with different Rolling properties and negative effects on the rolling mill and thus good surface qualities on the surface properties of the following products to obtain.
- the use of is special wear-resistant rollers are provided.
- rollers are proposed which were produced by powder metallurgy using the HIP process as well as rollers made of high-speed steel.
- the first casting machine 4 has a distributor 5 and one funnel-shaped thin slab casting mold (shown here schematically larger) for pouring thin slabs 40-100 mm thick.
- the casting machine 4 itself is fed with stainless steel melt from pans 7 in this example, the steel melt, for example, by means of a blast furnace converter route (designated 8) or with an electric steel furnace with downstream Secondary metallurgy has been manufactured and used for casting machines is transported in the pans 7 (the transport step is designated 9).
- the cast product in the form of the cast strand is removed from the vertical via rollers 10a, b bent into the horizontal and in this embodiment by means of a first cross-section shear 11 separated Then the individual run Thin slabs in a first leveling furnace 12, for example a roller hearth furnace or walking beam furnace to achieve a uniform thin slab temperature on. Then the thin slabs after going through one Descaling device 13 in the rolling mill to achieve the desired End dimensions promoted.
- the finishing line 14 of the rolling mill consists of here six roll stands (15a for example), each with two working (16a, b) and backup rolls (17a, b).
- An outlet roller table 18 with cooling devices closes 19 and a reel 20 for winding the tape onto the coil.
- the plant according to FIG. 1 shows a second cast product as casting strand 2 Carbon steel in a second, parallel process route II.
- This process route consists exclusively of the equalization furnace 21 from the same units as the process route I described above, which are therefore not discussed in detail becomes.
- the first process route comprises an integration unit for the thin slabs from the second process route II a ferry 22 which transversely into one the other side slidable portion 22a of the first leveling furnace 12 is insertable.
- a common rolling program is used in rolling mill 3 driven, an example of such a rolling program shown in FIG. 2 becomes.
- the respective steel grade is plotted on the number of strips.
- the rolling program starts after the change the work rolls with rolling a stainless steel cast product, followed by a cast product made of carbon steel etc.
- the sixth to eighth slab are then made of carbon steel, the 12th to 16th as a group made of stainless steel.
- figure 2 only serves as an example of a possible joint rolling program.
- the stainless steel rolling results in rougher roller surfaces that interfering with the immediately following rolling of carbon steel would, such as by rolling in scale and rougher Strip surfaces. That is why the rolling mill has grinding and / or polishing machines on which are arranged on each of the roll stands.
- At 23 is an example identified such a device that on the upper and lower Work roller works.
- an edge heater 24 is provided is arranged in front of the descaling device 13. It is for example an induction heater or gas-fired heater.
- tape quality can of course also be used and regulated control of profile actuators for shifting work rolls and improve roll bend adjustment.
- the order of entry of a first thin slab, a group of first thin slabs, i.e. from the first process route I, one second cast product or a group of second cast products in the Rolling mill and the duration of the common rolling program, i.e. the Time between changing the work rolls, computer-based Determine the basis of a process model. On basis. of this process model also the use and the period of the grinding and polishing equipment or the flushing devices for removing the scale of the carbon steels as well as other devices that improve the belt surface should be controlled. Such a control unit is designated schematically at 28.
- this rolling program according to a "mixed rolling" the permissible jumps in the width of the successive rolls Cast products are taken into account. Overall, is about such a process model an optimization of the rolling quality depending on the desired product quality possible.
- FIG. 3 corresponds to the first process route I shown in FIG. 1.
- the second integrated in the process route I Cast products (2) by means of a conventional casting machine 30 with thicknesses up to cast to 250 mm and after cooling and reheating if necessary a furnace 31 in a roughing stand 32 rolled down to a thickness, that they can be integrated into the common rolling mill of process route I. are.
- the conventional process of continuous casting and roughing is only here shown schematically.
- the individual slabs are cold or still warm condition to a slab furnace 21 near the first process route I transported, there heated to appropriate rolling temperatures or homogenized and introduced into the equalization furnace 12 by a ferry 22.
- FIG 4 shows schematically a second embodiment of the system with which a joint rolling program is carried out.
- the integration unit is a ferry 220, which both the cross-divided first and second cast products (100, 200), each of the two equalizing furnaces (120, 210) and thus process routes I and II come into a common rolling mill 300 promotes.
