Description

Technical Field

[0001] This invention relates to the field of non-ferrous metal smelting, specifically to a zinc ingot ladle and its manufacturing method. Background Technology

[0002] Zinc ingot casting commonly employs induction furnaces and ladle casting. The ladle is inserted into the induction furnace to scoop molten zinc and pour it into a mold. Traditional ladle designs are single or double ladle structures made of graphite. This method results in low casting efficiency, short lifespan, and easy breakage of the graphite ladle. Summary of the Invention

[0003] This invention provides a zinc ingot ladle and its manufacturing method. By setting up a partition, the strength of the casting section can be strengthened. Combined with the casting chamber, it can effectively reduce the impact of molten zinc during casting, prevent molten zinc from splashing, and ensure the casting stability of molten zinc. By using a shell to support, a pressure plate to clamp the casting section and the shell, and a bottom plate and cover plate to clamp and align the ladle section and the casting section, the stress on the ladle section and the casting section can be effectively reduced, reducing the risk of breakage. The ladle section and the casting section are made of high-temperature resistant materials, which have higher strength and longer service life.

[0004] A zinc ingot ladle includes a scooping section 1 and a casting section 2, with a through flow channel 3 between them. The casting section 2 has a bottom-opening partition 4, with the flow channel 3 and a casting chamber 5 at its two ends. The bottom of the casting chamber 5 has a casting port 6. The scooping section 1 and the casting section 2 are connected by a splicing device, which includes a housing 7, a base plate 9, a cover plate 10, and a pressure plate 12. The bottom of the housing 7 has a through hole 8. The casting section 2 is placed inside the housing 7 with the casting port 6 corresponding to the through hole 8. The pressure plate 12 clamps the casting section 2 to the housing 7. The scooping section 1 and the casting section 2 are clamped and aligned by bolts to fasten the base plate 9 and the cover plate 10.

[0005] Furthermore, a heat-resistant layer 13 is provided between the casting section 2 and the shell 7.

[0006] Furthermore, a cleaning hole 11 is provided on the cover plate 10.

[0007] Furthermore, the ladle comprises two units, each unit including a scooping section 1 with two flow channels 3 and a casting section 2, and the two casting chambers 5 on each unit are staggered.

[0008] Furthermore, the scooping section 1 and the casting section 2 are made of high-temperature resistant materials with the following composition: 65-75 parts by weight of silicon carbide, 20-30 parts by weight of silicon nitride, 1-5 parts by weight of silicon dioxide, 0.2-1.0 parts by weight of ferric oxide, 0.2-1.0 parts by weight of boron nitride, and 0.1-0.5 parts by weight of yttrium oxide.

[0009] Furthermore, the preferred material ratio for the high-temperature resistant materials in the scooping section 1 and the casting section 2 is: 69 parts by mass of silicon carbide, 26.7 parts by mass of silicon nitride, 3 parts by mass of silicon dioxide, 0.5 parts by mass of ferric oxide, 0.5 parts by mass of boron nitride, and 0.3 parts by mass of yttrium oxide.

[0010] Advantages of this invention:

[0011] 1. By setting up baffles, the strength of the casting section can be enhanced. Combined with the casting chamber, it can effectively reduce the impact of molten zinc during casting, prevent molten zinc from splashing, and ensure the casting stability of molten zinc.

[0012] 2. By using the shell support, pressure plate clamping the casting section and the shell, bottom plate and cover plate to clamp and align the scooping section and the casting section, the stress on the scooping section and the casting section can be effectively reduced, reducing the risk of breakage;

[0013] 3. The present invention uses high-temperature resistant materials to fire the scooping section and the casting section, which have higher strength and longer service life. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] Example 1

[0022] A zinc ingot ladle comprises two units, each unit including a scooping section 1 and a casting section 2, with two through-flow channels 3 between the scooping section 1 and the casting section 2; the casting section 2 is provided with a bottom-opening partition 4, with the flow channels 3 and casting chambers 5 at its two ends respectively; the two casting chambers 5 on each unit are staggered, and the bottom of the casting chambers 5 is provided with a casting port 6; the scooping section 1 and the casting section 2 are connected by a splicing device, which includes a shell 7, a bottom plate 9, a cover plate 10, and a pressure plate 12; the bottom of the shell 7 has a through hole 8, and the cover plate 10 has a cleaning hole 11; the casting section 2 is placed inside the shell 7 with the casting port 6 corresponding to the position of the through hole 8; a heat-resistant layer 13 is provided between the casting section 2 and the shell 7; the pressure plate 12 clamps the casting section 2 and the shell 7; the scooping section 1 and the casting section 2 are clamped and aligned by bolts to fasten the bottom plate 9 and the cover plate 10, and the cleaning hole 11 is aligned with the flow channels 3;

[0023] The aforementioned ladle is the zinc ingot ladle currently used by our company. Figures 1-5 As shown, it has 2 individual units, 4 flow channels and 4 casting ports, and can cast 4 zinc ingots at once.

[0024] The high-temperature resistant material composition of the scooping section 1 and the casting section 2 is as follows: 69 parts by mass of silicon carbide, 26.7 parts by mass of silicon nitride, 3 parts by mass of silicon dioxide, 0.5 parts by mass of ferric oxide, 0.5 parts by mass of boron nitride, and 0.3 parts by mass of yttrium oxide.

[0025] The aforementioned materials are stronger and have a longer service life than graphite. Furthermore, by supporting the shell, clamping the casting section and the shell, and aligning the scooping section and the casting section with the bottom plate and the cover plate, the stress on the scooping section and the casting section can be effectively reduced, thus reducing the risk of breakage.
