Description
Technical field
The utility model relates to mo(u)ld-box during casting six megawatt wind driven generator mainframe.
Background technology
Mo(u)ld-box cover slag ability, covering slag effect is the key ensureing casting quality, the magnesia that iron liquid generates after the spheroidising of rare earth Mg-Si alloy, the impurity such as magnesium sulfide, because density ratio is lower, in ladle, float to iron liquid surface gradually form scum silica frost, although carried out sufficient slagging-off after the spheroidising of stokehold, but because the ascent rate of these impurity is limited, may not have enough time to rise to molten iron surface and be solidified in foundry goods or float over cast(ing) surface and cause casting flaw in casting process, six megawatt blower fan mainframe ironcastings due to iron liquid measure large, iron liquid and air contact surfaces amass large, produce the more of bits, if these bits are brought together after being cast, just may have a strong impact on casting quality even causes foundry goods to be scrapped.
Utility model content
The utility model object is to overcome above-mentioned the deficiencies in the prior art, and slag ability is strong, to cover slag effective to provide one to cover, and is applicable to the mo(u)ld-box of the such heavy castings of six megawatt wind driven generator mainframes.
The technical solution of the utility model is: a kind of six megawatt wind driven generator mainframe mo(u)ld-boxs, comprise mo(u)ld-box casing, be provided with first point of casing in described casing, second point of casing, 3rd point of casing and the 4th point of casing, the top of casing is provided with runner box, is provided with two sprue gates in runner box, and two sprue gates are respectively by the main cast expanding channels first be arranged in casing and runner box inwall, 3rd point of casing and second, 4th point of casing, first, second, 3rd, also be tiltedly installed with in 4th point of cabinet wall and pour into a mould passage dividing of being connected with main cast passage, described point cast channel connection first, second, 3rd, the inside of the 4th point of casing, described point cast passage and main cast expanding channels place, sprue gate is all provided with plunger, and described plunger is connected with the Wrench for opening be arranged on cabinet exterior, and described runner box top is also provided with scum silica frost scraper plate, scratch board slide track and scum silica frost drain tank, scum silica frost scraper plate is slidably connected in scratch board slide track, and scum silica frost drain tank connects the scum pipe be arranged on outside casing, and scum pipe lower end is provided with slag trapping box.
Described casing top is also provided with exhaust rising head, avoids due to formation casting flaw of feeling suffocated.
First point of described casing, second point of casing, the 3rd point of casing and the 4th point of tank capacity are 25 tons.
Also be provided with filter screen in described main cast passage, in order to reduce molten iron turbulent flow, to filter slag, guarantee to fill type steady.
The beneficial effects of the utility model are: static by runner box, and make the impurity in iron liquid float to surface and form scum silica frost, scum silica frost is scraped to scum silica frost drain tank by scraper plate, and enters slag trapping box through scum pipe, is convenient to recycle; Pure iron liquid is poured in mo(u)ld-box by runner box bottom pouring mouth and cast passage.
Because iron liquid measure is close to 85 tons, design and produce point casing that four capacity are 25 tons, four iron liquid bags are adopted to carry out spheroidization and inoculation process respectively, after bonded hard ferrite magnet in runner box reaches 1330 DEG C (four points of spin manifold temperature differences are no more than 10 DEG C), first open the plunger of the 3rd, the 4th point of casing, open lower floor's running channel; After 40 seconds, open the plunger of another two casings, open upper strata running channel, such structural design greatly can reduce the content of scum silica frost in molten iron, improves the tensile strength of foundry goods, yield strength and percentage elongation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: casing 1, first point of casing 2, second point of casing 3, the 3rd point of casing 4, the 4th point of casing 5, runner box 6, sprue gate 7, main cast passage 8, point cast passage 9, scum silica frost scraper plate 10, scratch board slide track 11, scum silica frost drain tank 12, scum pipe 13, slag trapping box 14, exhaust rising head 15, filter screen 16.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of six megawatt wind driven generator mainframe mo(u)ld-boxs, comprise mo(u)ld-box casing 1, are provided with first point of casing 2 in described casing, second point of casing 3, 3rd point of casing 4 and the 4th point of casing 5, the top of casing 1 is provided with runner box 6, is provided with sprue gate 7,7, two, two sprue gates and is connected first respectively by being arranged on casing 1 with the main cast passage 8 in runner box inwall 6 in runner box 6, 3rd point of casing 2, 4 and second, 4th point of casing 3, 5, first, second, 3rd, 4th point of casing 2, 3, 4, also be tiltedly installed with in 5 inwalls and pour into a mould passage 9 dividing of being connected with main cast passage 8, a described point cast passage 9 is communicated with first, second, 3rd, 4th point of casing 2, 3, 4, the inside of 5, described point cast passage 9 and main cast passage 8 junction, sprue gate 7 is all provided with plunger, and described plunger is connected with the Wrench for opening 17 be arranged on cabinet exterior, and described runner box 6 top is also provided with scum silica frost scraper plate 10, scratch board slide track 11 and scum silica frost drain tank 12, scum silica frost scraper plate 10 is slidably connected in scratch board slide track 11, and scum silica frost drain tank 12 connects the scum pipe 13 be arranged on outside casing 1, and scum pipe 13 lower end is provided with slag trapping box 14, described casing 1 top is also provided with exhaust rising head 15, first point of described casing 2, second point of casing 3, 3rd point of casing 4 and the 4th point of casing 5 capacity are 25 tons, are also provided with filter screen 16 in described main cast passage 8.
