End.
Mainly cast tube inside is caused to damage: be entrained into inside cast tube first is that being washed coating, second is that since local surfaces apply
Expect defect, liquid metal is caused directly to contact with metal mold, liquid metal is changed in crust due to thermal coefficient, especially
Its local overcooling surface when being poured large-sized heavy-wall tube generates interlayer and pipe shaft cracking.
Chinese utility model patent is disclosed, and application number CN201620626244.5, patent name: Mould Coating for Centrifugal Cast is stirred
Machine is mixed, the applying date: 20160623, it discloses a kind of Mould Coating for Centrifugal Cast blenders.The utility model in order to solve it is existing from
The problem of coating suspension is poor, gas production big influence cast tube product quality of heart cast tube coating blender configuration, provides one kind
Mould Coating for Centrifugal Cast blender, including shell, shaft and motor, shaft are driven by motor and are vertically installed in shell, shaft
It is equipped with upper layer and lower layer stirring blade, the cover top portion is equipped with raw material addition mouth and filler, outer casing bottom are unloaded equipped with coating
Outlet.It is reliable that the structure design of the utility model is reasonable, and the use of variable-frequency motor and multiple layers of stirring blades piece improves spun cast pipe and stirs
The production efficiency for mixing machine, improves coating quality, improves the product quality of spun cast pipe, in particular improves beauty, Europe superscript etc.
The qualification rate of gray cast iron thin-walled spun cast pipe exported product.
Utility model content
The utility model provides a kind of spun cast pipe and enters to infuse cast gate, in view of the above drawbacks of the prior art, provide it is a kind of from

Round mouth croissant 4 is stated in " L " shape, the horizontal ends of the round mouth croissant 4 are provided with overflow lip seam close to a side-lower of liquid outlet
Road 5, the length of the overflow lip seam 5 are greater than the internal diameter of 4 horizontal ends of round mouth croissant.
Preferably, the length of the overflow lip seam 5 is 3 times of the internal diameter of 4 horizontal ends of round mouth croissant.
Preferably, the seam area of the overflow lip seam 5 is into the 50% of cast gate area.
Preferably, setting is there are two parallel groove circle on 1 outer surface of mould cylinder, clamping pair under each groove circle
The idler wheel 2 answered.
Preferably, the internal diameter of the horizontal ends of the round mouth croissant 4 is 100mm.
Preferably, the length of the overflow lip seam 5 is 300mm, and the width of the overflow lip seam 5 is 12mm, the institute
The length for stating the horizontal ends of round mouth croissant 4 is 700mm.
Preferably, 4 vertical end of round mouth croissant is in up-side down triangle, the inlet of 4 vertical end of round mouth croissant
Internal diameter be 290mm.
The coating of mould cylinder inner wall is impacted the utility model has the beneficial effects that reducing molten steel, is effectively ensured solidifying inside cast tube
Gu when oriented and ordered progress, so that cast tube inner non-metallic field trash and gas is suspended in upper surface in cast tube, pole by centrifugal force

Specific embodiment
As shown in Figure 1 it is found that the utility model includes: mould cylinder 1 and idler wheel 2, the clamping of idler wheel 2 are arranged in mould cylinder 1
Groove circle under, the both ends of the mould cylinder 1 pass through die cap 3 respectively and close, in the slave die cap 3 of one end of 1 liquid inlet of mould cylinder
It wears and injects round mouth croissant 4, the round mouth croissant 4 is in " L " shape, and the horizontal ends of the round mouth croissant 4 are close to liquid outlet
One side-lower is provided with overflow lip seam 5, and the length of the overflow lip seam 5 is greater than the internal diameter of 4 horizontal ends of round mouth croissant.
Preferred in this embodiment, the length of overflow lip seam 5 is 3 times of the internal diameter of 4 horizontal ends of round mouth croissant.
In use, in molten steel liquid outlet in the case where flow is constant, the overflow lip length of overflow lip seam 5 doubles, and is going out
Slot open flow divides in advance at mouth, and molten steel original is changed into the molten steel of elliptical beam high speed undershoot and prolongs 70% advection molten steel of axial shunting,
Change small molten steel to impact the coating of mould cylinder inner wall, molten steel is made to become orderly flowing into high-speed rotating gold from the state of original disorder
Belong to the shape body in mould cylinder, oriented and ordered progress when cast tube solidified inside is effectively ensured, makes cast tube inner non-metallic field trash and gas
Body is suspended in upper surface in cast tube, significant effect by centrifugal force.
