Definitions
- the invention relates to a roller block for a
- Support frame for storing at least one lower support roller, a strand guide and a billet caster with such a roller block.
- Irregularities in the cooling of the metal strand can lead to the stick not having the desired shape.
- a rhombic cross section can be created instead of a desired rectangular cross section.
- Irregular cooling will take place, for example, if the steel strand is not centric and symmetrical with respect to the center line of the strand guide, or the Center line of the strand guide channel is positioned. Then the intervals of coolant will be applied
- Steel strand may be different. Associated differences in the cooling intensity can lead to a shape defect
- Spray bar with the cooling nozzles not symmetrical with respect to the center line of the strand guide - that is, with respect to the
- roller guides on the strand guide must also be exact
- a device is to be provided with which the risk of asymmetrical arrangement, as well as the effort and the susceptibility to errors in the symmetrical arrangement, of spray bars or cooling nozzles can be reduced in billet continuous casting plants.
- Support frame for storing at least one lower support roller, characterized in that the roller block
- Holding devices for attaching spray bars includes.
- the billet caster is preferably suitable for
- the metal strand is led through the strand guide in an arc from the mold through the secondary cooling chamber to the WSU and to the outlet area or roller table.
- Roller supports in support frames
- Strand guide rollers support and guide the metal strand, they practically form a strand guide channel.
- the lower support roller is used to guide and support the outer arch of the metal strand.
- the metal strand has a beginning on the mold side and an end on the roller table side.
- the metal strands in the region of the secondary cooling chamber are generally supported by means of support rollers in roller blocks in such a way that the areas between adjacent roller blocks in which no support is provided are many times longer than the length of the metal strand passing through a roller block.
- Spray bars include cooling nozzles from which through the
- Spray cooling liquid - for example cooling water - is sprayed onto the metal strand.
- Intermediate area spray bars are spray bars that allow the cooling of the metal strand in the intermediate areas - that is, the areas of the strand guide of a secondary cooling chamber in which the metal strand does not pass through roller blocks. It is not a spray bar that only allows cooling in a roller block between and / or next to support rollers of the roller block.
- holding devices for fastening intermediate area spray bars are present on the roller blocks of a strand guide.
- the roller stands are precisely aligned with each other and define the strand guide channel. If the intermediate area spray bars are attached to the roller stands that are already exactly aligned with each other, the cooling nozzles are symmetrical to the center line of the
- cooling in the area of the roller block can also be easily carried out in the immediate vicinity of the roller block - this enables more uniform cooling than with conventional ones Design in which intermediate area spray bars are brought less close to roller stands.
- the roller block preferably also comprises at least one line suitable for introducing spray cooling liquid into intermediate area spray bars.
- the introduction can be direct or indirect - for example via a hose between the line and the intermediate area spray bar. This allows a more compact and simple design
- Spray coolant integrated in the intermediate area spray bars in the support frame This allows a more compact and simple construction of a billet caster.
- Support frame can then, for example, as a carrier for the
- the support frame can consist of hollow components that guide the spray coolant in the cavities from feed points to connection points for the intermediate area spray bars.
- a line frame comprising the line for introducing spray cooling liquid into the intermediate area spray bars is fastened to the support frame.
- the line frame preferably also comprises holding devices for fastening intermediate area spray bars.
- Another object of the present application is a strand guide of a secondary cooling chamber for a
- Billet caster characterized in that it comprises at least one roller stand according to the invention.
- Another object of the present application is a billet caster, characterized in that they attached a strand guide according to the invention to a secondary cooling chamber with roller stands according to the invention
- Intermediate area spray bar includes. Existing roller stands can easily be opened
- Figure 1 shows schematically the general scheme of a conventional billet caster with sheet guide with a secondary cooling chamber.
- Figure 2 shows a roller stand according to the invention.
- Figure 3 shows a section of a secondary cooling chamber with roller block according to the invention.
- FIG. 1 shows schematically in an oblique view how in a billet caster 1 a metal strand 2, for example a steel strand, in a strand guide 3 in an arc from the mold 4 via the secondary cooling chamber 5 and WSU 6 to
- Roller table 7 is performed. Supporting rollers 10 supported in guide frames 9 in support frames 9 support and guide it, they practically form a strand guide channel.
- Chilled beams 11a and 11b are shown on racks 12 above and below the metal strand; schematically shown are intermediate area spray bars, which in the intermediate areas - that is Areas of the strand guide of a secondary cooling chamber in which the metal strand does not pass through roller blocks - allow the cooling of the metal strand.
- Metal strand is shown schematically. Arranged to the right and left along the metal strand as seen from the mold to the roller table next to the metal strand
- Figure 2 shows a roller block 13 according to the invention for a strand guide of a billet caster, with a
- Support frame for mounting a lower support roller 14 and an upper support roller 15.
- the lower support roller 14 is mounted on the support frame part 16a, and the upper support roller 15 carrying rockers 17a, 17b are supported on the support frame part 16b.
- a plurality of holding devices 18a, 18b, 18c, 18d, 18e, on the support frame part 16a and on the support frame part 16b are
- the roller block also includes a line suitable for introducing spray cooling liquid into intermediate area spray bars; this line is integrated in the support frame part 16b.
- a line suitable for introducing spray cooling liquid into intermediate area spray bars is integrated in the support frame part 16b.
- Support frame part 16a can be supplied with cooling liquid for cooling the support frame part 16a via the cooling liquid connection 21.
- FIG. 3 shows a section of a secondary cooling chamber with a roller block 22 according to FIG. 2 according to the invention
- roller block 22 according to the invention, intermediate area spray bars 23, 24, 25, 26, 27, 28 are fastened, for example to the holding devices 29a, 29b, 29c, 29d visible in FIG. 3 on the support frame parts 30a and 30b.
- Other existing ones are possible to be used to make up
- Holding devices are not visible in Figure 3. It is shows how spray coolant is fed via hoses 31a, 31b to the intermediate area spray bars 26 and 27 from connection points 32a, 32b.
- cones such as from spray nozzles 33, which are symmetrical with respect to the center of the strand guide, that is to say with respect to the center line of the strand guide channel,
- Roller blocks are cooled between the support frame parts 30a and 30b.
