Definitions

  • the invention relates to a system for horizontal strip casting of a pre-strip of metal.
  • the strip casting plant has a melting vessel from which melt is fed via a pouring nozzle onto a horizontally encircling casting belt.
  • a cooling device is arranged under an upper run of the casting belt.
  • the abandoned melt solidifies to a preliminary band.
  • the strip casting plant has an enclosure into which a gas stream is introduced in order to form a reducing or oxidizing atmosphere or an inert gas atmosphere for the discontinued melt and the solidifying pre-strip.
  • the gas stream is introduced via nozzles which are arranged in a ceiling element of the housing.
  • the gas flow is varied with regard to its temperature and its speed and pressure profile.
  • a horizontal strip caster for producing a pre-strip of steel is known.
  • a circulating casting belt of the strip casting plant is coated with a coating composition consisting of a carrier liquid and additives prior to the application of a melt in the region of an upper side facing the pre-strip.
  • additives are a wide variety of metals or metallic oxides / nitrides / borides, with which the material properties of the pre-band can be specifically influenced.
  • the carrier liquid is removed in a drying unit.
  • a firmly adhering coating of the steel strip may alternatively be formed, via the thickness of which the heat transfer between the casting strip and the pre-strip and thus the cooling rate of the melt or pre-strip can be controlled.
  • German publication DE 10 2012 001 469 A1 relates to a horizontal strip caster for producing a pre-strip.
  • a discontinuous melt solidifies on a casting belt which, after complete through-stiffening of the pre-strip, is subjected to conditioning in an in-line process.
  • This conditioning includes at least one of annealing, drying, straightening, brushing, cleaning, descaling, stretching, smoothing or coating.
  • Possible permanent coatings are ceramics or metal / ceramic compounds.
  • renewable coatings are dispersing layers of BN, nitrides, oxides or carbides in question. On the basis of the coating, the heat transfer between the casting belt and the pre-strip can be controlled.
  • the publication WO 2007/071225 A1 relates to a horizontal strip casting plant for producing a pre-strip of light-weight steel, in particular. It is proposed a casting belt, which is provided to reduce the heat transfer and the contact between itself and the solidifying to a Vorband strand with a structure. This structure has longitudinally extending beads or nubs distributed over the surface, which are impressed into the casting tape from above.
  • the German patent application DE 28 56 472 concerns, among other things, a continuous casting mold belt casting for casting aluminum and aluminum alloys.
  • the mold has a roughened surface to control the heat transfer on first contact with the molten metal.
  • the mold surface has a roughness pattern consisting of a regular array of pyramid or frusto-conical elevations, so that the melt only the tips of these elevations of the mold surface touched.
  • the bulging then causes the melt to shift in the direction of the center of the strip, thereby causing already solidified dendrites to come to the surface of the strip, at which point no lid formation has yet taken place.
  • the formation of a dense, non-porous surface can be hampered by the low heat removal at the top of the belt and a correspondingly lower solidification rate and unfavorable flow boundary layers by the flow of the atmosphere.
  • the present invention is based on the object to provide a system for horizontal strip casting of a pre-strip of metal, with an improved geometry and surface of the pre-strip, increased output and thus a significant improvement in efficiency is achieved.
  • the casting tape is provided in the region of a solidifying upper surface facing the upper surface with a surface structure, an improved geometry and surface of the pre-strip, an increased yielding and thus a significant improvement in efficiency achieved that the surface structure is created by a shaping shaping of the casting belt.
  • an embossing reshaping is understood to mean a production method in which indentations or elevations on the upper side of the casting strip are formed together with oppositely arranged elevations or indentations on the underside of the casting strip. Elevations on the top of the casting belt thus correspond at the same place with indentations on the underside of the casting belt or vice versa. In this manufacturing method, there may be deviations between the shape of the indentations or elevations on the top and bottom, in order to obtain or optimize the desired shape on the top.
  • this stamping process for the production of casting tapes is particularly well that it is simple and inexpensive and is shifted by the stamping only material in the thickness direction of the casting belt and thus preserving the original dimensions of the casting belt. There are no or hardly any changes in the length and width of the casting belt, which would have resulted in corresponding rework.
  • the surface structure is formed regularly.
  • the surface structure has a first pattern in the middle region and, optionally, a pattern different from the first pattern in the edge regions.
  • the uniform heat dissipation is effected in an advantageous manner by preventing the lifting of the cast pre-strip.
  • the homogenization of the cooling conditions over the bandwidth affects a deformation of the cast Vorbandes (U-shape) contrary.
  • different solidification of the pre-strip is counteracted and thus local porosities and voids, which often occur linearly in the casting, avoided.
  • an improvement in the quality, the surface and the geometry of a produced Vorbandes especially for alloys with low Al contents - preferably Al ⁇ 0.8 wt .-% - achieved by the homogenization of the cooling conditions.
  • the application is increased and associated with the economy.
  • the casting tape at least in the region of an upper side facing the solidifying precursor, is made of a material having a thermal conductivity of greater than 90 W / mK (at 40 ° C.), in particular greater than 100 W / mK (at 40 ° C.) is and has a casting tape thickness of 0.5 to 3 mm, in particular from 1 to 3 mm.
  • materials are particularly suitable aluminum, an aluminum alloy, copper or a copper alloy.
  • the use of aluminum, aluminum alloy, copper or copper alloy as cast strip material further allows an increase in the casting strip thickness with the same or improved heat dissipation, whereby a buckling of the casting belt is counteracted and in particular a homogenization of the heat dissipation over the surface.
  • the casting tape is provided with a surface structure at least in the region of the solidifying pre-band facing surface and the surface structure preferably a tear, pyramid, diamond, bead or dot pattern with a depth of 0.075 to 0.8 mm in the sense of indentations or elevations.
  • a stiffening of the structure is achieved and increases the heat dissipation down and homogenized and improves the heat conduction also within the casting belt. It follows that the production by imprinting reshaping the casting belt on a bottom of the casting belt elevations or indentations are arranged opposite to the indentations or elevations on the top of the casting belt.
  • a further alternative or additional embodiment provides that the casting tape in the region of an upper side facing the solidifying pre-band can have a different pattern and a 20 to 75% higher embossing depth of the structure in edge regions in each case up to a maximum of 25 cm from the edge in the direction of the tape center.
  • a cast strip with reduced thermal conductivity is used. Due to the reduced thermal conductivity of the casting belt, the heat dissipation is delayed down and thus increases the proportion of solidification of the Vorbandoberseite and promoted the formation of a lid on the Vorbandoberseite during casting. This is particularly advantageous for steels with an increased tendency to surface defects and open porosity, where a casting belt of an alloy with higher thermal conductivity would otherwise cause the metallurgical center (area of residual solidification) to move in the cast pre-strip toward the strip surface. Alloys with an Al content of less than 0.8% by weight and a solidification interval greater than 30 ° C. are counted among the surface-sensitive grades, as well as steels containing high C and high Si.
  • the casting tape for reducing and delaying the heat dissipation down at least in the region of a solidifying upper band facing top made of a material having a thermal conductivity of less than 35 W / mK (at 40 ° C) and a casting strip thickness of 0, 5 to 3 mm.
  • a material having a thermal conductivity of less than 35 W / mK (at 40 ° C) and a casting strip thickness of 0, 5 to 3 mm are stainless steels, high Cr steels and FeNi alloys.
  • Particularly advantageous are the low expansion coefficients of, for example FeNi alloys, which additionally counteract a bulging of the pre-strip.
  • the dense oxide layer improves the separation behavior between the casting strip and the cast pre-strip.
  • the casting belt is formed of a plurality of materials, wherein the casting belt, in particular in the edge regions in each case up to a maximum of 25 cm from the edges seen from another Material consists of the middle part of the casting belt.
  • the casting belt can be constructed in such a way that materials with different thermal conductivities are used selectively in order to influence the local cooling conditions. The difference in thermal conductivity should be at least 20%.
  • materials in the middle of the band are particularly suitable aluminum, aluminum alloys, copper and copper alloys with a thickness of 0.5 to 3 mm.
  • materials preferably made of micro-alloyed structural steel or stainless steel with a thickness of 0.5 to 3 mm are advantageous.
  • the casting tape over the bandwidth has a varying thickness.
  • the edge regions have a thickness which is at least 10% different from the center, and the transition between the regions of different thickness can take place both stepwise and preferably continuously. As a result, an optimization of the heat dissipation is achieved.
  • a casting belt having different material thicknesses between the center region and the edge region is used in conjunction with stainless steels or FeNi alloys having a thickness of 0.5 to 3 mm.
  • the material is at least 10% thicker in the edge areas than in the center areas. This causes a reduction in heat dissipation.
  • a further alternative or additional embodiment provides that the casting tape in the middle region consists of a micro-alloyed structural steel and in the edge region of a high-Cr steel or stainless steel.
  • the reduced thermal conductivity of the edge region of the casting belt advantageously reduces heat dissipation, thereby avoiding undesirably rapid cooling of the edge regions.
  • the casting tape is completely or partially provided with a coating which preferably contains BN, ZrO 2 , TiO 2 , Al 2 O 3 or AlN.
  • the layer thickness is chosen so that a heat transfer is reduced by at least 5%. As a result, a heat transfer from the cast pre-strip is reduced to the casting belt.
  • the reduced heat dissipation leads to a reduction of band distortions (for example, the known U-shape) of the produced Vorbandes.
  • band distortions for example, the known U-shape
  • these belt distortions are caused by excessive local heat dissipation in the area of the strip edges.
  • FIG. 1 The schematic side view of a horizontal strip casting plant 1 essentially consists of a melting vessel 2, a pouring nozzle 3, a casting belt 4 and an enclosure 5.
  • liquid melt S in particular molten metal
  • the endless casting belt 4 runs in a casting direction G about a front deflection roller 4a and a rear deflection roller 4b spaced therefrom in the casting direction G and thus conveys the solidifying precursor V in the casting direction G.
  • the casting belt 4 can be moved into an upper strand 4c, on which the Vorband V solidifies, and a lower strand 4d between the front and rear pulleys 4a, 4b split.
  • a strand 4c, 4d is understood to mean that part of the casting strip 4 which extends between the deflection rollers 4a, 4b.
  • the casting belt 4 runs substantially horizontally in the region of the upper strand 4c and is cooled in the region of the upper strand 4c by means of a cooling device 7 from below, almost all of the upper strand 4c, with the exception of short regions at the transition to the deflection rollers 4a, 4b with coolant, preferably water, applied.
  • the housing 5 of the horizontal strip caster 1 surrounds the solidifying precursor V in a region between the pouring nozzle 3 and an outlet 5b for the solidified supernatant V from the housing 5.
  • the housing 5 is provided in a conventional manner to the melt S in a reducing atmosphere , an oxidizing atmosphere, an inert gas atmosphere or a casting atmosphere, which is adapted to the chemical composition of the melt to shed and solidify to the Vorband V.
  • a gas supply line 5c and a gas discharge line 5d are connected to the housing 5 in the region of an upper and substantially horizontally extending ceiling element 5a of the housing 5.
  • the gas supply line 5c is located in the region of the outlet 5b and the gas discharge line 5d in the region of the pouring nozzle, so that the gas flows counter to the pouring direction G in countercurrent to the solidifying precursor V or vice versa.
  • Such horizontal strip casters 1 are particularly suitable for the production of close to near-demarcated Vorband with strip thicknesses in the range of 6 to 25 mm (measured in the band center) from high manganese or high aluminum or high silicon lightweight steels, electrical steel or other high or low alloy steel.

  • a first pattern 7 in a center region M on the surface of the casting belt 4 is different from a second pattern 8 of the surface of the casting belt 4 in the edge regions R which are laterally adjacent to the center region M.
  • the edge regions R point in the casting direction G, respectively a width of up to a maximum of 25 cm - measured from the edge of the casting belt 4 - on.
  • the second pattern 8 leads to a changed heat transfer, in particular a reduced heat transfer in the edge regions R, compared with the center region M.
