Abstract
The present invention relates to a spheroidized ladle-casting device which belongs to the field of production devices of nodular graphite cast iron. The present invention has the technical scheme that the spheroidized ladle-casting device comprises a ladle body, a covering ladle is arranged at the top of the ladle body, and a through hole is formed between the covering ladle and the ladle body. The present invention is characterized in that a permeability plug is arranged between the covering ladle and the ladle body. The present invention has the advantages that when a liquid alloy is filled, gas in the ladle body can ascend to leak out through the permeability plug, the pressure in the ladle body can be adjusted, and Mg steam in the ascending gas can be absorbed and utilized again in the liquid alloy in the covering ladle.
Description
Technical field
The present invention relates to a kind of process units of spheroidal graphite cast-iron, relate in particular to a kind of Spheroidized ladling apparatus.
Background technology
In the prior art with the immediate prior art of the present invention be on May 15th, 2002 the disclosed patent No. be 01244056.6 patent of invention, it discloses a kind of spheroidising bag, comprise inclusion and rotating shaft, inclusion top is provided with lid bag, in the lid bag hole is set and inclusion communicates.The deficiency that this invention exists is: 1. since through hole when injecting liquid alloy, gas in the inclusion rises but almost can not be excessive, injection along with liquid alloy, gas pressure in the inclusion is more and more higher, has reduced the speed that liquid alloy falls to inclusion from the lid bag, for this reason, the content of magnesium can not be too high in the nodulizer in the inclusion, the too high reaction speed of magnesium is too fast, and the pressure in the inclusion raises fast, easily causes molten iron to splash from the lid bag.2. along with the gas pressure in the inclusion is more and more higher, increased the danger of operation.In a word, the pressure in the inclusion is excessive, is unfavorable for workman's safety and spheroidising, is unfavorable for that the secondary of uprising gas absorbs, and so-called secondary absorbs when being the interior gas rising of inclusion by the liquid alloy in the lid bag, and the magnesium vapor in the gas is absorbed by molten iron.
Summary of the invention
Technical assignment of the present invention is at the existing in prior technology shortcoming, and provide a kind of technical scheme of spheroidising bag, gas rising when fluid injection in the inclusion can be overflowed excessive by porous plug, can regulate the pressure in the inclusion, the gas of rising can be absorbed and used in the lid bag once more.
The present invention realizes by following technical measures: it comprises inclusion, be provided with the lid bag at the top of inclusion, be provided with through hole between lid bag and the inclusion, between lid bag and inclusion, also be provided with porous plug, porous plug specifically can adopt graphite to make cylinder, be drilled with on the cylinder and the homoaxial micropore of cylinder, the diameter of micropore is 0.5～3mm.Adopt this structure that the liquid of injection can not be passed through from micropore, the gas in the while inclusion can rise again and overflow.
This scheme is when injecting liquid alloy, gas rising in the inclusion can be overflowed excessive by porous plug, can regulate the pressure in the inclusion, magnesium vapor in the gas that rises can be absorbed and used in the liquid alloy of lid bag once more, improved the absorptivity of nodularization element, can reduce the addition of nodulizer, make the addition of nodulizer descend 0.4%, the trade mark of nodulizer specifically can adopt REMg5-8, one ton of qualified magnesium iron spare of every production can be saved the 7kg nodulizer, nodulizer per ton is by 8000 yuan of calculating, one ton of qualified magnesium iron spare of every production can reduce cost 56 yuan, reduce the decline of molten iron temperature in the spheroidising process, improved the degree of purity of molten iron, improved the yield rate of magnesium iron spare.
Be connected closely in order to make between lid bag and the inclusion, the present invention has also done further improvement, and the top of inclusion outer wall is provided with disk, there is the retaining edge disk outer ring, the outer wall bottom of lid bag extends to disk upper surface, at lid bag outer wall, is filled with sealer in the space that inclusion outer wall and disk form.Can keep the pressure in the inclusion like this, prevent that the magnesium vapor nodulizer in the inclusion from overflowing with smog, it has saved nodulizer on the one hand, the another side environment protecting is good, magnesium light MgO in the smog is very big to eyes harm, even can cause the temporary blindness of eyes, and adopt the present invention can effectively avoid the magnesium vapor nodulizer to overflow with smog, operating personnel and environment all there are suitable benefit.
Above-mentioned sealer specifically can adopt, and at lid bag outer wall, being filled with sealer in the space that inclusion outer wall and disk form is that diameter is 90～150 purpose sands.The lid bag is sitting on the inclusion, fills up tiny sand in the space that forms between lid bag and inclusion outer wall and disk, reaches the purpose of sealing pressurize.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
Wherein, 1. sand, 2. through hole, 3. porous plug, 4. flame retardant coating, 5. lid bag, 6. retaining edge, 7. disk, 8. inclusion.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
The present invention is a kind of Spheroidized ladling apparatus, as shown in Figure 1, it comprises inclusion 8, be provided with lid bag 5 at the top of inclusion 8, be provided with through hole 2 between lid bag 5 and the inclusion 8, be provided with porous plug 3 between lid bag 5 and inclusion 8, be drilled with and the homoaxial micropore of cylinder on the cylinder of porous plug 3 for the graphite making, the diameter of micropore is 0.5～3mm.The top of inclusion 8 outer walls is provided with disk 7, and there is retaining disk 7 outer rings along 6, and the outer wall bottom of lid bag 5 extends to disk 7 upper surfaces, and at lid bag 5 outer walls, filling diameter in the space that inclusion 8 outer walls and disk 7 form is 90～150 purpose sands 1.
