Abstract
The invention discloses a molten aluminum runner so that the problem that time and labor are wasted since impurities such as aluminum oxide and calcium oxide are manually cleaned away in the prior art can be solved. The molten aluminum runner comprises a settling basin and flow channels connected to two corresponding sides of the settling basin. The bottom of the settling basin is lower than the bottoms of the flow channels. A baffle perpendicular to the flow channels in direction is arranged in the middle of the settling basin. The bottom of the baffle is higher than the bottom of the settling basin but lower than the bottoms of the flow channels. The impurities such as the aluminum oxide and the calcium oxide are blocked on one side of the settling basin through the baffle and cannot enter follow-up casting, and the quality of aluminum bars is guaranteed; besides, after all molten aluminum flows out, the impurities can sink to the bottom of the basin and then cleaned away in a unified mode, the impurities are cleaned away more conveniently compared with the traditional mode that the impurities are cleaned away while casting is carried out, and a great amount of labor force is saved.

Aluminium, silvery white light metal, has ductility, and commodity often make bar-shaped, sheet, foil-like, powdery, band shape and thread, can form the oxide-film that one deck prevents metal erosion in humid air.Aluminium powder and aluminium foil in atmosphere heating energy fiercely burn, and send the white flame of dazzling the eyes.Be soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, NaOH and potassium hydroxide solution, be insoluble in water.Relative density 2.70, fusing point 660 DEG C, boiling point 2327 DEG C.The content of aluminium element in the earth's crust is only second to oxygen and silicon, and occupying the 3rd, is the metallic element that in the earth's crust, content is the abundantest.The development of aviation, building, the large essential industry of automobile three, require that material behavior has the peculiar property of Aluminum-aluminum alloy, this is just conducive to production and the application of this new metallic aluminium greatly, and therefore aluminium application is very extensive.
In the casting process of aluminium bar, the aluminium liquid in holding furnace needs to carry out the techniques such as deoxidation, normally adds calcium oxide etc., and then aluminium liquid is added deep-well casting system by chute carries out being cast as aluminium bar.Although aluminium liquid can take off Slag treatment to it before flowing out from holding furnace, be difficult to thoroughly clean out, so unavoidably can containing impurity such as calcium oxide.And when aluminium liquid flows in chute, surfaces of aluminum liquid and air bump contact, be oxidized to aluminium oxide, and if no matter calcium oxide or aluminium oxide participate in the casting of aluminium bar, capital badly influences and casts out aluminium bar quality, must clear up these impurity.And traditional labor cleaning is too wasted time and energy, therefore the present inventor devises a kind of aluminium spout of Automatic clearance impurity.
Summary of the invention
The invention is intended to provide a kind of aluminium spout, to solve in prior art by problem that the impurity such as labor cleaning's aluminium oxide and calcium oxide are wasted time and energy.
A kind of aluminium spout in this programme, comprise settling tank, the both sides that described settling tank is relative are connected to the runner passed through for aluminium liquid, lower than at the bottom of runner at the bottom of described settling tank, baffle plate is straight down provided with, higher than at the bottom of settling tank and lower than at the bottom of runner bottom described baffle plate in the middle part of described settling tank.
The operation principle of this programme and beneficial effect:
The runner of aluminium liquid through settling tank side flowed out in holding furnace enters settling tank, owing to being provided with baffle plate in the middle part of settling tank, higher than at the bottom of settling tank and lower than at the bottom of runner, therefore aluminium liquid can flow downward bottom baffle plate, by the opening below baffle plate, then flow out from the runner of settling tank opposite side.Such aluminium liquid forms the flow trace of " U " shape in settling tank, add the time of staying in aluminium liquid settling tank, the impurity such as the calcium oxide be blended in aluminium liquid are allowed to have the sufficient time to leave standstill, because the density of impurity is less than the density of aluminium liquid, so impurity can float to aluminium liquid surface gradually.Aluminium liquid contact with oxygen formed aluminium oxide also swim in also swim in aluminium liquid surface, then due to the existence of baffle plate, make this two classes impurity be blocked in settling tank side, do not enter follow-up casting, ensure that the quality of aluminium bar.And these impurity can, after aluminium liquid stream is complete, sink at the bottom of pond, unified cleaning, convenient more a lot of than casting limit, traditional limit cleaning impurity, decrease a large amount of labours.
Further, the bottom of described settling tank sidewall is provided with aluminium liquid effuser, due at the bottom of described settling tank lower than at the bottom of runner, when aluminium liquid stream in runner is complete, also remains part aluminium liquid in settling tank and cannot flow out, if the later stage solidifies, can be difficult to cleaning, and this part aluminium liquid wastes.Therefore be provided with aluminium liquid effuser in the bottom of settling tank sidewall, when the duty of casting, block aluminium liquid effuser by asbestos, ensure its normal aluminium liquid flowing.After casting terminates, taken out by asbestos, aluminium liquid residual in settling tank is flowed out by aluminium liquid effuser, these aluminium liquid can be added recycling in holding furnace, avoid the waste of aluminium liquid, and ensure the normal operation of settling tank.
Further, in the middle part of described settling tank, be provided with the groove matched with baffle plate, like this when needing to clear up the aluminium slag in settling tank, baffle plate may hinder cleaning work, at this moment baffle plate can be extracted out from groove, and when needing the baffle plate of other height, can arbitrarily change.
Further, the settling tank degree of depth is 1.0-1.25m, and flow channel depth is 0.5m, and height of baffle plate is 0.7-1.0m.If flow channel depth is excessively dark, each hierarchy temperatures change of aluminium liquid can be caused too greatly, the temperature of aluminum liquid of bottom is lower, flowing velocity is slow, the efficiency of casting process will reduce, if and flow channel depth is too shallow, the aluminium liquid measure so flowed is little, casting process will be slow, more expend time in cost, if therefore the degree of depth of balanced runner is more difficult, inventor is through long production work, when finding that flow channel depth is 0.5m, most effective, the most suitable, and the degree of depth of settling tank and the cooperation of height of baffle plate, the flowing velocity of aluminium liquid in settling tank can be regulated, can remove the gred too soon not thorough, too slowly, understand temperature to reduce, even solidify passage, therefore through the test of inventor, obtaining the settling tank degree of depth is 1.0-1.25m, when height of baffle plate is 0.7-1.0m, the most suitable.
