Abstract
The invention discloses an aluminum alloy casting filter unit comprising a heat preserving furnace, a degassing unit, a filter unit and a casting machine, wherein the outlet of the heat preserving furnace is connected with the inlet of the degassing device through a middle chute A; the outlet of the degassing device is connected with the inlet of the filter unit through a middle chute B; the outlet of the filter unit is connected with the casting machine through a movable chute; the horizontal height of the middle chute B is larger than that of the movable chute; and the height difference of the middle chutes and the movable chute is 180-220 mm. The aluminum alloy casting filter unit ensures that metal or nonmetal included slag in molten aluminum in the filter unit has enough floating or sinking time, the pressure of the molten aluminum is increased, the flow rate of the molten aluminum is increased, normal level height for casting is ensured effectively, and the possibility of causing slag deposition and blockage of filter plates in the filter unit is low due to high flow rate of the molten aluminum.
Description
Technical field
The present invention relates to a kind of casting device, relate in particular to a kind of aluminium alloy casting filter.
Background technology
In the production process of Birmasil, may there be solid-state non-metallic inclusion in the aluminum melt, oxide is generally arranged, carbide, nitride, hydride etc., that these impurity are brought into except raw material and since prepurging not thorough, batch mixing, thermo electric material is fallen into etc. beyond the artificial reason, also mainly due to aluminum melt and furnace lining, instrument, various refining agents, produce various physical-chemical reactions in the process of additive contact and generate and enter melt, the refractory material of furnace lining usually by various oxides as AL2O3, Fe2O3, Cr2O3, mixtures such as SiO2 are formed, when melt contacts with furnace lining, if the generation heat of these oxides is lower than the generation heat of aluminium oxide, then furnace lining will be decomposed, and separate out the low metal impurities of specific activity aluminium.
Aluminum melt is poured out through degasification and filter from the holding furnace introversion, the filter of ordinary circumstance melt by making by neutrality or active material, make the field trash in the melt reach the purpose that eliminating separates through the obstruct of filtration machinery or with the chemical action of its material, netted filtering is arranged, foam ceramic filter, micropore ceramic tube filtration etc., no matter be the sort of filter type, from the filter to the casting machine, at present domestic drop is about 50mm, aluminium liquid flowing velocity is slow, easy accumulated slag, usually cause filter inner filtration plate to stop up, every 1-2 stove need be changed filter, yet temperature height in the filter need be opened the lid of filter when changing filter, heat scatters and disappears seriously on the one hand, changes operational difficulty on the other hand.
Summary of the invention
Purpose of the present invention just is that providing a kind of addresses the above problem, and does not need frequent replacing filter, has both improved the filtration purity of aluminium liquid, improved again filter service life, reduced the aluminium alloy casting filter of cost.
To achieve these goals, the technical solution used in the present invention is: a kind of aluminium alloy casting filter, comprise holding furnace, depassing unit, filter and casting machine, wherein the outlet of holding furnace links to each other with the inlet of depassing unit by intermediate chute A, the outlet of depassing unit links to each other with the inlet of filter by intermediate chute B, the outlet of filter connects casting machine by mobile chute, the level height of intermediate chute B is greater than mobile chute, and the difference in height of intermediate chute B and mobile chute is 180mm ~ 220mm.
As preferably: the difference in height of described intermediate chute B and mobile chute is 200mm.
Compared with prior art, the invention has the advantages that: the difference in height of having raised intermediate chute B and mobile chute, when aluminium liquid through the batching, stir, take a sample pour holding furnace into after qualified after, enter depassing unit from holding furnace through intermediate chute A and carry out degasification, enter filter through intermediate chute B again, because the difference in height of intermediate chute B and mobile chute is 180mm ~ 220mm, then at this moment, the aluminium liquid phase is to volume in the filter, highly increase, make interior metal of aluminium liquid or nonmetal slag inclusion come-up or sink to having time enough, but also increased the aluminium hydraulic coupling, accelerated aluminium liquid flowing velocity, effectively guaranteed the normal liquid level of casting, because aluminium liquid flowing velocity piece, be not easy accumulated slag, be difficult for causing filter inner filtration plate to stop up.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, holding furnace; 2, intermediate chute A; 3, depassing unit; 4, intermediate chute B; 5, filter; 6, mobile chute; 7, casting machine.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Embodiment: referring to Fig. 1, a kind of aluminium alloy casting filter, comprise holding furnace 1, depassing unit 3, filter 5 and casting machine 7, wherein the outlet of holding furnace 1 links to each other with the inlet of depassing unit 3 by intermediate chute A2, the outlet of depassing unit 3 links to each other with the inlet of filter 5 by intermediate chute B4, the outlet of filter 5 connects casting machine 7 by mobile chute 6, the level height of intermediate chute B4 is greater than mobile chute 6, and the difference in height of intermediate chute B4 and mobile chute 6 is 180mm ~ 220mm, in the present embodiment, the difference in height of described intermediate chute B4 and mobile chute 6 is 200mm.
When aluminium liquid through the batching, stir, take a sample pour holding furnace 1 into after qualified after, enter depassing unit 3 from holding furnace 1 through intermediate chute A2 and carry out degasification, enter filter 5 through intermediate chute B4 again, because the difference in height of intermediate chute B4 and mobile chute 6 is 180mm ~ 220mm, then at this moment, the aluminium liquid phase is to volume in the filter 5, highly increase, make interior metal of aluminium liquid or nonmetal slag inclusion come-up or sink to having time enough, but also increased the aluminium hydraulic coupling, accelerated aluminium liquid flowing velocity, thereby, can not only effectively guarantee to cast normal liquid level, also be not easy accumulated slag, be difficult for causing filter 5 inner filtration plates to stop up.
According to actual operating position, before the improvement,, change once each 2 about former per 4 stoves according to every month production 150 stoves.Now can change by 6 stoves, can change 300 of filters less in 1 year, save mint of money.
Claims (2)
1. aluminium alloy casting filter, comprise holding furnace, depassing unit, filter and casting machine, wherein the outlet of holding furnace links to each other with the inlet of depassing unit by intermediate chute A, the outlet of depassing unit links to each other with the inlet of filter by intermediate chute B, the outlet of filter connects casting machine by mobile chute, it is characterized in that: the level height of intermediate chute B is greater than mobile chute, and the difference in height of intermediate chute B and mobile chute is 180mm ~ 220mm.
