Abstract
The invention discloses a kind of chute, for foundry's aluminium liquid cast, including arc-plane bottom land（1）, arc-plane bottom land（1）On have a downward concave regions（2）, concave regions（2）Including declining face（2‑1）And raised floor（2‑2）, raised floor（2‑2）It is interior to stop provided with arc obstacle（3）.Simple structure of the present invention, can play the function of effectively collecting slag, prevent the appearance of product slag inclusion situation.
Description
Technical field
The present invention relates to a kind of chute that aluminium liquid cast is carried out suitable for foundry, the particularly section of chute and knot
Structure.
Background technology
In aluminum ingot casting, slag inclusion phenomenon can be produced, traditional cast is that arc is flat with chute, it is impossible to effectively prevent material residue
Into aluminium pig casting machine, so as to influence product quality.
Forming the main cause of slag inclusion has a lot：1st, holding furnace or the tool of production used are unclean；2nd, aluminium liquid is quiet
Slag hitting is not clean when putting refining；3rd, pouring temperature is too low, and aluminium liquid poor fluidity, slag inclusion can not float；4th, during melting additive into
Sub-control system is inaccurate, and multiple feed supplement, stirring etc. make aluminium liquid oxidation exacerbation, and oxide-film or slag are brought into aluminium alloy.
As shown in figure 1, the bottom land for being chute in traditional chute structure schematic diagram, figure is arc flat-bottom structure, i.e. chute
The inner surface at bottom is arc, and the minimum point on straight line all in a plane of arc.Slag inclusion in aluminium liquid can relatively hold
Easy enters in casting machine running gate system, so as to influence casting quality, increases percent defective.
The content of the invention
The technical problem to be solved in the present invention is：A kind of chute for foundry's aluminium liquid cast is provided, played effectively
The function of slag is collected, the appearance of product slag inclusion situation is prevented.
The technical solution adopted by the present invention is：Have on a kind of chute, including arc-plane bottom land, arc-plane bottom land one to
Under concave regions, concave regions include decline face and raised floor, stop provided with multistage arc obstacle in raised floor.Due to bottom land
Adding the slag in one section of concave regions, aluminium liquid has a process for falling and rising when this concave regions flows, this
The mating reaction that change stops plus successively arc obstacle so that slag can be good at being blocked, and collect in the matrix area
In domain.Chute effectively realizes blocking by above-mentioned construction, collects the function of slag.
The length of raised floor is more than the length in decline face, and the gradient is less than the gradient in decline face, so longer relatively slow
Raised floor can reduce the fluctuation produced when aluminium liquid flowing is hampered and precipitate and collect to slag there is provided more distances, prevent smaller
Slag inclusion particle follow metal wave flow out recess region.
Arc obstacle stops that the arc of upper surface is identical and highly identical with the inner surface arc of arc-plane bottom land, i.e.,
Arc obstacle stops that circular arc apparent height maintains an equal level with surface at flat chute, to keep aluminium liquid section in whole chuting system big
Small is overall consistent, does not form bottle-neck zone, does not influence poring rate.
The section profile line of the concave regions is section connected straight line of broken line, i.e., two, corresponds respectively to raised floor with
Drop face.The corresponding broken line gradient of raised floor is relatively delayed, and allows slag fully to precipitate and be blocked, and declining the corresponding broken line in face can be with
It is relatively steep, improve the deposition velocity of larger particles slag in aluminium liquid.
This chute is identical with traditional flat chute butted part section holding, and aluminium liquid flowing velocity is not influenceed, convenient to install.
Its structure in the middle part of original chute equivalent to setting one from two ends to middle gradually capable downward concave regions, in aluminium liquid flowing
The concave regions second half section in direction（Raised floor）Set multiple（Such as 3-4）Arc obstacle stops that obstacle stops at concave arc
Surface（Upper surface）Not higher than（Typically it is equal to）The bottom surface of the flat chute of tradition（Arc-shaped inner surface）.
The aluminium water that upstream is come carries slag inclusion and flows through slag inclusion in the chute, aluminium liquid along chute slope（Decline face）Enter recessed
Shape region lowest part, the arc obstacle for being raised face stops that clean aluminium water enters downstream.Multiple tracks arc obstacle stops favourable
Different size of scum silica frost is removed in multistage., can be effective by setting a number of this kind of chute in cast chuting system
The effect for collecting slag inclusion is reached, so as to ensure the quality of aluminium liquid cast.

Embodiment
As shown in Fig. 2~Fig. 5, a kind of chute for foundry's aluminium liquid cast, including arc-plane bottom land 1, arc
There are the concave regions 2 that a downward section profile line is polyline shaped on planar slot bottom 1, concave regions 2 include decline face 2-1 and upper
Rise in face 2-2, raised floor 2-2 provided with four road arc obstacles stops 3.Raised floor 2-2 length is more than decline face 2-1 length,
The gradient is less than the decline face 2-1 gradient.Arc obstacle stops that 3 height of upper surface 4 is equal to the arc of the arc-plane bottom land 1 at two ends
Shape inner surface height（I.e. both are in same level）, and the arcuate shape of the two is identical.The aluminium water carrying clamp that upstream is come
The slag inclusion that slag is flowed through in the chute, aluminium liquid declines face 2-1 along chute and enters the lowest part of concave regions 2, is raised face 2-2 arc
Shape obstacle stops that 3 stop, clean aluminium water enters downstream.
