The spheroidizing ladle comprises a ladle cover (6) and a ladle body (7), wherein the ladle cover (6) and the ladle body (7) are connected with each other by a bolt (5); a pouring gate (1), a tundish (2), a charging hole (3) and a charging hole cover (4) are formed on the ladle cover (6); the spheroidizing ladle is characterized in that a microporous vent plug or permeable brick (8) is arranged at the lower part of the side surface or on the bottom surface of the ladle body (7); the microporous vent plug or permeable brick (8) is connected with a gas conveying conduit (8) for blowing reducing gases or inert gases; before spheroidizing, the reducing gases or the inert gases are blown in by the microporous vent plug or permeable brick; under the protection of the reducing gases or the inert gases, the spheroidizing is performed, so that burning loss of a spheroidizing agent and oxidation of an iron liquid can be reduced, the usage of the spheroidizing agent is obviously reduced and the spheroidizing effect and cast quality stability are improved; and molten iron splashing and magnesium light are eliminated, dust and smoke are reduced, and working environments of workers are improved.
Description
Technical field
The utility model relates to a kind of spheroidising bag of producing spheroidal graphite cast-iron.
Background technology
Spheroidal graphite cast-iron is the very good cast iron materials of a kind of mechanical performance, and the quality of spheroidization of graphite quality directly has influence on the mechanical property of spheroidal graphite cast-iron.The rank of spheroidization of graphite is high more, and promptly globular graphite is more little, and shape is more regular, and it is even more to distribute, and then the performance of spheroidal graphite cast-iron is good more.
At present, domestic most widely used nodulizing process is to pour method, and the spheroidising bag is uncovered structure; Molten iron directly is injected in the spheroidising bag, and nodulizer contacts with air with molten iron, causes the burning of magnesium in the nodulizer; Make that the absorptivity of nodulizer is lower, consumption is more, and nodularization is unstable; The product quality fluctuation is big, and percent defective is higher.Simultaneously produce a large amount of magnesium lights and flue dust in the nodularization process, molten iron splashes seriously, and deterioration labourer's working environment impacts operator's physical and mental health.
For solving the above-mentioned problem that exists in the method spheroidising that pours, the nodularization of lid bag method progressively is applied in process of production, and lid bag method is in the method spheroidising of the pouring portion of wrapping a tundish to be installed it is sealed, and only is connected through cast gate between pack processing and the tundish.The nodularization of lid bag method can improve the absorptivity of magnesium, reduces fume amount, and can't see magnesium light in the course of the work basically, has improved workman's work situation.But contain air in the general lid bag, can not stop the problem of oxidation of nodulizer and molten iron.
The utility model content
For further reducing the scaling loss of nodulizer, improve the absorptivity and the iron liquid degree of purity of magnesium, it is higher to obtain nodulizing grade; Steady quality, the ductile cast iron material of excellent performance, the utility model provide a kind of spheroidising bag with gas shield; Comprise clad and inclusion; Clad is connected through bolt with inclusion, and clad is provided with cast gate, tundish, charging aperture and hole cover, is provided with micro-porous permeable plug or air brick in the bottom, side or the bottom surface of inclusion.Before the spheroidising; Add nodulizer, inovulant and coverture from charging aperture; Micro-porous permeable plug or air brick through bottom, inclusion side or bottom surface are blown into reducibility gas or inert gas; Reducibility gas that is blown into or inert gas volume are 1.5～2 times that the spheroidising inclusion amasss, after air process cast gate and charging aperture are discharged in the nodularization bag, stop to blow.Under reducibility gas or inert gas shielding, iron liquid flows into inclusion through tundish on the clad and cast gate and carries out spheroidising.After the spheroidising, can carry out Argon to iron liquid and handle, Argon pressure should be selected according to iron liquid measure difference, generally can overcome the static pressure of iron liquid, can just form bubble on iron liquid surface and be advisable.
The beneficial effect of the utility model is:
The utility model is blown into reducibility gas or inert gas through the micro-porous permeable plug or the air brick of bottom, inclusion side or inclusion bottom surface, discharges the air in the pack processing through cast gate and charging aperture.During spheroidising, can reduce the scaling loss and the iron liquid oxidation of nodulizer, the use amount of nodulizer reduces 10～20%, has reduced production cost, has improved nodularization effect and quality stability; Can eliminate that molten iron splashes and magnesium light, reduce dust, smog, improve labourer's working environment, help the healthy of operator; After the spheroidising; The utility model can also require decision whether to carry out the Argon processing according to the spheroidal graphite cast-iron product quality, and the bag BOTTOM ARGON BLOWING is handled and can be made its composition even, reduces gas content in the iron liquid; Promote the non-metallic inclusion come-up, thereby improve iron liquid degree of purity and casting quality.

Wherein, 1. cast gate, 2. tundish, 3. charging aperture, 4. hole cover, 5. bolt, 6. clad, 7. inclusion, 8. micro-porous permeable plug or air brick, 9. gas transmission conduit, 10. nodulizer, 11. rotating shafts.
The specific embodiment
Below in conjunction with specific embodiment the utility model is described further:
Shown in the accompanying drawing 2 is another preferred embodiment of a kind of spheroidising bag with gas shield, and the difference of the embodiment shown in itself and the accompanying drawing 1 is that micro-porous permeable plug or air brick 8 are arranged on the bottom surface of inclusion 7.
Before the spheroidising; Add nodulizer 10, inovulant and coverture through charging aperture 3, the micro-porous permeable plug or the air brick 8 of (like accompanying drawing 1) or bottom surface (like accompanying drawing 2) are blown into reducibility gas or inert gas from bottom, inclusion side, are example with the argon gas; The amount of being blown into is long-pending 1.5～2 times of spheroidising inclusion; Air is discharged through cast gate 1 and charging aperture 3, can stop to be blown into argon gas, cover hole cover 4.During spheroidising, molten iron is injected the tundish 2 on the clad, molten iron gets into inclusion 7 through cast gate 1 and carries out spheroidising, with nodulizer 10 reactions in the inclusion 7, under argon shield, accomplishes the spheriodization process thereof of molten iron.Also can continue to be blown into argon gas after the spheroidising, iron liquid is stirred, make its composition even, reduce gas content in the iron liquid, promote the non-metallic inclusion come-up, thereby improve iron liquid degree of purity and casting quality.
Because nodulizer and iron liquid are isolated with air in the airtight pack processing of argon gas is arranged, so magnesium can not burn.Thereby improved the absorptivity of magnesium, reduced the addition of nodulizer, reduced production cost, improved nodularization effect and quality stability, eliminated molten iron and splash and magnesium light, reduced dust, smog, improved labourer's working environment.Fig. 3 is not for carrying out the metallograph after the blowing argon nodularization before the spheroidising, Fig. 4 for before the spheroidising through the metallograph after the blowing argon nodularization.Can find out that from Fig. 3 and Fig. 4 the nodularization quality of process blowing argon is higher than the nodularization quality without blowing argon, its graphite sphere diameter is less, and roundness is higher, is uniformly dispersed.
