Abstract
A nozzle end is provided with an extension 11 which has a lower portion immersed in a molten metal pool and extends toward a side weir 2 such that a stagnation area disappears on a free liquid surface of molten metal.
The extension 11 is in the form of a quadrangular pyramid lying sidelong and is converged to a point P1 extremely close to the side weir 2.
According to this molten metal feed nozzle, a stagnation area on a free liquid surface of molten metal is displaced by the extension 11 contiguous with the nozzle end to suppress generation of an unwanted solidification shell. Thus, no unwanted solidification shell is pinched as foreign matter by solidification shells generated on outer peripheries of chilled rolls 1 for production of a strip and break of a strip derived from enlargement of nip between the rolls can be averted.
Description
- The present invention relates to a molten metal feed nozzle incorporated in a twin roll caster
-
FIG. 1 shows an example of a twin roll caster with a pair ofchilled rolls 1 arranged horizontally and in parallel with each other and a pair ofside weirs 2 associated with thechilled rolls 1. - The
rolls 1 through which cooling water flows interiorly are adapted to increase or decrease a nip or gap G between the rolls depending upon thickness of astrip 3 to be produced - Rotational directions and velocities of the
rolls 1 are set such that respective outer peripheries of the rolls are moved from above toward the nip G at constant velocity. - One and the other of the
side weirs 2 are urged to surface-contact one and the other ends of therolls 1, respectively. In a space surrounded and defined by theside weirs 2 androlls 1, a molten metal feed nozzle made of refractory is positioned just above the nip P between the rolls. - The feed nozzle has an
elongated nozzle trough 5 which in turn has a top opened for reception ofmolten metal 4 and longitudinal side walls formed at their lower ends with a plurality ofopenings 6 for passage from thetrough 5 to the outer peripheries of therolls 1, the openings being spaced apart from each other axially of the rolls. By pouring themolten metal 4 into thenozzle trough 5, amolten metal pool 7 is formed above the nip G between the rolls and in contact with the outer peripheries of therolls 1. - More specifically, when the
molten metal pool 7 is formed and the rolls l chilled by passage of the cooling water are rotated, themolten metal 4 is solidified on the outer peripheries of therolls 1 and thestrip 3 is delivered downwardly from the nip G between the rolls. - Since wear on sliding portions of the side weirs relative to the
rolls 1 progresses in direct proportion to accumulative operational time period, force for urging theside weirs 2 against therolls 1 is gradually increased to prevent leakage of themolten metal 4 from between such members. - Molten metal feed nozzles incorporated in twin roll casters may be divided into those with ends of the nozzle which surface-contact the side weirs 2 (see, for example, Reference 1) and those with ends of the nozzle which are spaced apart from and in parallel with the
side weirs 2 sees for example, Reference 2). - However, in application of a structure in
Reference 1, the molten metal feed nozzle remains unchanged in its longitudinal size. Thus, as the wear on the sliding portion of theside weir 2 progresses, leakage of themolten metal 4 becomes unsuppressed by merely increasing the force for urging theside weirs 2 to therolls 1. - In application of a structure in
Reference 2, as shown inFIG. 10 , flow velocity distribution at free liquid surface of themolten metal 4 tends to be low at between two parallel surfaces facing to each other i.e., asurface 9 of the side weir on the molten metal pool and anend wall surface 10 of the molten metal nozzle, in comparison with at between a longitudinalside wall surface 8 of the molten metal nozzle and thechilled roll 1. As a result, an area A where themolten metal 4 tends to stagnate is formed especially from theend wall surface 10 to a point P0 which is an intersection of nip center line L with thesurface 9 of the side weir. - It occurs in the stagnation area A that the
molten metal 4 is lowered in temperature due to radiation heat transmission and a solidification shell is generated which is unwanted for the free liquid surface of themolten metal 4 and for theend wall surface 10 of the nozzle. - When such unwanted solidification shell is pinched as foreign matter by the solidification shells generated on the outer peripheries of the
chilled rolls 1 upon rotation of the rolls, thestrip 3 may be locally thickened into defective shape and/or the nip G between the rolls may be enlarged depending upon part of thestrip 3 where the foreign matter is pinched, resulting in break of thestrip 3 due to reduction in cooling efficiency and heat recuperation from themolten metal 4. - The invention was made in view of the above and has its object to provide a molten metal feed nozzle which can avert break of a strip
- In order to attain the above object, the invention is directed to a molten metal feed nozzle positioned above a nip between rolls of a twin roll caster and having ends spaced apart from side weirs comprising extensions each contiguous with the nozzle end and extending toward the side weir such that a stagnation area disappears on a free liquid surface of molten metal.
- In the invention, the extensions eliminate stagnation areas of the free liquid surface of the molten metal; they prevent the molten metal from being lowered in temperature due to radiation heat transmission and suppress generation of unwanted solidification shells.
- According to a molten metal feed nozzle of the invention, the following excellent effects and advantages can be obtained.
- (1) The extensions prevent the molten metal adjacent to the side weirs from being lowered in temperature and suppress generation of solidification shells on the free liquid surface of the molten metal, so that unwanted solidification shells are not pinched as foreign matter by the solidification shells generated on the outer peripheries of the chilled roll for production of the strip, and thus break of the strip derived from enlargement of the nip between the rolls can be averted.
- (2) When the extensions are shaped to be converged toward the side weirs for gradual reduction in volume of the extensions, heat transmission from the molten metal to the extensions is reduced so that the molten metal adjacent to the side weirs is effectively prevented from being lowered in temperature.

FIGS. 3 to 6 show a first embodiment of a molten metal feed nozzle according to the invention in which parts identical with those inFIGS. 1 and 2 are represented by the same reference numerals. - Each of nozzle ends is provided with an
extension 11 which has a lower portion immersed in amolten metal pool 7 and extends toward aside weir 2 such that a stagnation area A (seeFIG. 2 ) disappears on a free liquid surface ofmolten metal 4. - The
extension 11 is in the form of a quadrangular pyramid lying sidelong and is convergent to point P1 extremely close to theside weir 2. - In the twin roll caster with such molten metal feed nozzle incorporated, the stagnation area A on the free liquid surface of the
molten metal 4 is displaced by theextension 11 contiguous with the nozzle end to suppress generation of an unwanted solidification shell. As a result, no unwanted solidification shell is pinched as foreign matter by the solidification shells generated on the outer peripheries on thechilled rolls 1 for production of thestrip 3, whereby break of thestrip 3 due to enlargement of the nip G between the rolls can be averted. - In addition, the
extension 11 is gradually reduced in volume toward theside weir 2, so that heat transmission from themolten metal 4 to theextension 11 is reduced. As a result, themolten metal 4 adjacent to theside weir 2 can be effectively prevented from being lowered in temperature and no unwanted solidification shell for theside weir 2 is generated. -
FIGS. 7 and 8 shows a second embodiment of a molten metal feed nozzle according to the invention. In the figures, parts identical with those shown inFIGS. 3 to 6 are represented by the same reference numerals. - Each of nozzle ends is provided with an
extension 12 which has a lower portion immersed in amolten metal pool 7 and extends toward aside weir 2 such that a stagnation area A (seeFIG. 2 ) disappears on a free liquid surface ofmolten metal 4. - The
extension 12 is wedge shaped and is converged to a horizontal line segment between points P2 and 23 extremely close to theside weir 2. - In the twin roll caster with such molten metal feed nozzle incorporated the stagnation area A on the free liquid surface of the
molten metal 4 is displaced by theextension 12 contiguous with the nozzle end to suppress generation of unwanted solidification shell. As a result, no unwanted solidification shell is pinched as foreign matter by the solidification shells generated on the outer peripheries of thechilled roll 1 for production of thestrip 3, whereby break of thestrip 3 due to enlargement of the nip G between the rolls can be averted. - In addition, the
extension 12 is gradually reduced in volume toward theside weir 2, so that heat transmission from the molten metal 4 (seeFIG. 6 ) to theextension 12 is reduced so that themolten metal 4 adjacent to theside weir 2 can be effectively prevented from being lowered in temperature and no unwanted solidification shell for theside weir 2 is generated. -
FIGS. 9 and 10 show a third embodiment of a molten metal feed nozzle according to the invention. In the figures, parts identical with those inFIGS. 3 to 7 are represented by the same reference numerals. - Each of nozzle ends is provided with an
extension 13 which has a lower portion immersed in amolten metal pool 7 and extends to aside weir 2 such that a stagnation area A (seeFIG. 2 ) disappears on a free liquid surface ofmolten metal 4. - The
extension 13 is in the form of tapered quadratic prism lying sidelong and is converged to vertical face with corners P2, P3, P4 and P5 extremely close to theside weir 2. - In the twin roll caser with such molten metal feed nozzle incorporated, the stagnation area A of the free liquid surface of the
molten metal 4 is displaced by theextension 13 contiguous with the nozzle end to suppress generation of unwanted solidification shell. As a result, no unwanted solidification shell is pinched as foreign matter by the solidification shells generated on the outer peripheries of thechilled roll 1 for production of thestrip 3, whereby break of thestrip 3 derived from enlargement of the nip G between the rolls can be averted. - Heat transmission from the molten metal 4 (see
FIG. 6 ) to theextension 13 may be much in comparison with the first and second embodiments; however, the third embodiment is easier in machining upon fabrication of the molten metal feed nozzle. - It is to be understood that a molten metal feed nozzle of the invention is not limited to the above embodiments and that various changes and modifications may be made without departing from the scope of the invention.
- A molten metal feed nozzle of the invention is applicable to production of strips of steel or other various metals.
