Definitions
- the invention relates to a method for producing steel strips by means of strip casting according to the preamble of claim 1 and to a device according to claim 10.
- a method of the generic type for producing steel strips by means of strip casting is known (Steel Research 74 (2003), No. 11/12, page 724-731).
- this known as DSC process manufacturing method is suitable for the production of hot strip of lightweight steel.
- melt is fed from a feed vessel via a runner and a siphon-like discharge nozzle formed as a casting nozzle on a revolving casting belt of a horizontal strip casting.
- the discontinued melt solidifies to a pre-strip with a thickness in the range between 6 to 20 mm. After solidification, the pre-strip is subjected to a hot rolling process.
- a disadvantage of this strip casting plant is that it can lead to caking during operation on the outlet side region of the casting nozzle, which increasingly reduce the outlet cross section for the melt. As a result, there is an uneven supply of the liquid steel to the belt and consequently to casting defects. Investigations into the cause of the caking have shown that on the one hand, the lower compared to the melt temperature at the casting nozzle allows the formation of deposits, on the other hand, the existing ceramic casting nozzle is wetted during melting of emerging on the melt surface oxides, which adhere there and then form an ideal surface for further growth of the caking.
- the caking forms especially in the critical triple point of Keramikg mandüse, circulating cooled casting belt and liquid molten metal and flow-unfavorable areas.
- the object of the invention is to provide a method for producing steel strips by means of strip casting, in which the previously described problems are avoided, but at least significantly reduced. Another object is to provide a device for carrying out the method.
- At least one plasma jet which inactivates and heats the exposure region acts on the outlet-side region of the casting nozzle and on the melt emerging therefrom, at least during the casting process.
- the inventive method is basically suitable for the production of hot strips of various metallic materials, especially for lightweight steels, such as high modulus HSD ® steels.
- the operating times and thus the profitability of the strip casting plant and the quality of the cast strip can be significantly increased.
- the plasma is ignited in a conventional manner by high voltage or high frequency inductively or capacitively in the burner itself or against the molten metal and maintained with DC or AC.
- the strength (intensity) of the plasma is advantageously set via a set of rules consisting of a gas mixing, pressure and flow regulator and a control device for the electrical parameters.
- an inert gas such as argon or nitrogen used.
- plasma gas but in addition to argon and nitrogen, other individual gases or gas mixtures with additions of H 2 , CO, CO 2 or CH 4 and other combinations can be used.
- the surface (surface tension) of the metal film can be influenced very well.
- existing hydrogen very well prevents the oxidation of the melt surface.
- the flow behavior of the metal film and thus the wettability of the ceramic with regard to the prevention of caking can advantageously be influenced.
- a nozzle-like element designed as an argon screen is arranged in front of the casting nozzle, which nozzle blocks the liquid steel on the casting nozzle
- the argon rake is modified in such a way that one or more plasma torches can be integrated one after the other into the system, viewed one below the other or in the direction of melt flow, so that a structural unit is formed.
- the plasma torches are positioned so that they can act on the edge area in particular over the entire width of the pouring nozzles.
- the use of multiple burners is advantageous because it can increase the efficiency of inerting and heating.
- the plasma torches act sectorally on the outlet-side casting nozzle area, wherein optimal targeted heating of the casting nozzle over its width or over the width of the exiting melt bath can be carried out via a specific separate temperature control of the individual burners.
- the assembly is inventively made of a good heat conducting material, such. As copper, prepared and is cooled intensively with water.
- the jet direction of the plasma torch is advantageously adjusted slightly inclined downwards in the direction of the liquid steel against the casting direction, in order to be able to influence the melt pool surface in a targeted manner.
- the plasma torches are also slightly aligned in the direction of the edge region of the exiting melt.
- FIG. 1 in a plan view, a schematic representation of the casting nozzle region of a strip casting plant according to the invention
- Figure 2 as Figure 1 in a side view.
- FIG. 1 shows a plan view of a schematic representation of the casting nozzle region of a strip casting plant according to the invention.
- Metal melt 7 runs in this illustration from left to right and is indicated by an arrow.
- an assembly 4 according to the invention made of an argon rake for the uniform distribution of melt on the surface of the casting belt 3 and plasma torches 9 (FIG. 2) is shown made of copper.
- the plasma torches 9 are arranged so that their plasma jets 5 completely inertize the exit region of the molten metal 7 from the casting nozzle and the melt surface and can control the temperature of the melt.
- the nozzles 6 of the argon rake are directed obliquely downward onto the molten metal 7.
- FIG. 2 shows the pouring nozzle region in a side view according to section A - A from FIG. From this view, which also consists of ceramic upper part 8 and the lower part 8 'of the pouring nozzle can be seen.
- the assembly 4 with argon rake and plasma torches 9 is arranged in the outlet region of the molten metal 7 from the casting nozzle so that on the one hand the nozzles 6 ( Figure 1) of the argon rake distribute the exiting molten metal uniformly on the casting belt 3 and on the other hand the plasma jets 5 of the plasma torch 9 the exit region can completely inertize.
- the plasma torches 9 are inclined according to the invention in the direction of the exiting melt.
- the plasma torch 9 are cooled by cooling water bores 10 by means of water and supplied via a plasma gas supply 11 with plasma gas.
