Description
Technical field
The utility model relates to a kind of double-stage filtering case apparatus with two heating functions, belongs to aluminium alloy D.C.casting device technique field.
Background technology
What of inclusion are the purity that improves aluminium liquid to aluminium and aluminium alloy cast ingot quality important influence in the aluminium liquid, generally when aluminium and aluminium alloy cast ingot are produced adopt filtering method to remove non-metallic inclusion in the melt.It is several that filter type mainly contains glass wool cloth filtration, deep-bed filtration, vitrified pipe filtration and foamed ceramic filter plate filtration etc. at present.Foamed ceramic filter plate filters because of easy to use and characteristics such as cost is low, filtration efficiency height have obtained being extensive use of, and has become the preferred manner of industrial aluminum filtration liquid at present.
Along with the raising that ingot quality is required, the purity requirement to aluminium liquid during casting is also more and more higher, and the aperture of screen plate is more and more littler when therefore adopting foamed ceramic filter plate aluminum filtration liquid.Aluminum current and aluminium alloy cast ingot adopt vertical semi-continuous casting technology to produce mostly, and at the casting initial period, aluminium liquid temperature after chute, air-removal equipment etc. installs strumbox descends, and is easy to stop up filter pore.For avoiding aluminium liquid to stop up filter pore, to carry out thermal pretreatment to screen plate as last in the casting beginning.Preheating method commonly used has two kinds of combustion gas heating and resistive heating.
Adopt the drawback of combustion gas type of heating to be, if existing aluminium liquid in the strumbox, fuel gas buring causes gas content increase in the aluminium liquid easily, so the strumbox that adopts the combustion gas type of heating does not possess the function of Insulating aluminium liquid, after casting finishes, must put the aluminium liquid in the strumbox dried, all new screen plate will be installed before each casting time beginning, production cost is higher.And the strumbox of employing resistive heating, aluminium liquid can be incubated in the strumbox between two castings are inferior, and screen plate is reusable.
But, when adopting resistive heating such as screen plate adopt the mode that stacks up and down, when preheating, be difficult to be heated to lower floor's screen plate.Therefore screen plate need be put in strumbox in series connection from front to back, and its weak point is that strumbox length is big, has increased production line length, waste material.

Embodiment
The utility model designs a kind of compact construction, has the strumbox of two heating functions, to realize the repeated use of screen plate, saves cost, and reduces the labour intensity that the workman changes screen plate.
As shown in Figure 1, aluminum liquid two-stage strumbox with two heating functions comprises housing 4, liner 5 and loam cake 9, and liner 5 is lining in the housing 9, on a sidewall of housing, be provided with aluminium liquid inlet 1, accordingly, on relative sidewall, be provided with aluminium liquid outlet 7, upper and lower two screen plates are installed in liner 5, promptly go up screen plate 2 and following screen plate 3, last screen plate 2 specifications are 30～50ppi, and following screen plate 3 specifications are 50～70ppi, leave the gap between two screen plates.Filtering chamber can be single chamber, also can be two chambeies in parallel side by side, and upper and lower two screen plates are installed in each filtering chamber, and a weif orifice 6 is arranged on casing.Gas-preheating burner 11 is installed on loam cake 9, and gas-preheating burner 11 is right against screen plate; Also the inwall at loam cake 9 is provided with resistance heating element 8.Temperature thermocouple 10 is installed on loam cake 9, and temperature thermocouple 10 stretches in the chamber of liner.Different steps in casting adopts different heating units to heat, and at pre-heating stage, starts 11 pairs of screen plates of gas-preheating burner and carries out preheating; In castingprocesses, close Sweet natural gas, can heat by 8 pairs of aluminium liquid of starting resistance heating unit, also can not enable resistive heating; Between two castings time, served as and adopted the resistance wire heating when needing to retain a part of aluminium liquid in the filter box, temperature of aluminum liquid between 680～760 ℃, thereby realize the repeated use of screen plate.
The main difference of above-mentioned strumbox and existing regular foam ceramic plate strumbox is: it has combustion gas, resistance two jacket heating systems, resistance heating element 8 is installed on the strumbox loam cake 9, gas-preheating burner 11 is installed in the position that faces the screen plate middle position, strumbox for two groups of screen plates in parallel (is connected 2 up and down for every group, totally 4 screen plates), at loam cake two gas-preheating burners 11 are installed, resistance heating element 8 evenly is installed in loam cake 9 inwall positions.In the preheating screen plate stage, at first start gas-preheating burner 11, the high-temperature gas heating and filtering plate that utilizes combustion gas to produce; After the casting beginning, close burner, can heat aluminium liquid by starting resistance heating unit 8, reach the casting requirement as temperature of aluminum liquid and can not enable resistive heating according to the production practical situation; Casting can also be satisfied the filtration requirement as screen plate after finishing, and then need not change screen plate, keeps a part of aluminium liquid and adopt the mode of resistive heating to be incubated in strumbox, and temperature of aluminum liquid is between 680～760 ℃, until next one casting time beginning; Screen plate is changed as needing in casting end back, aluminium liquid can be drained from weif orifice 6, adopts gas-preheating again behind the replacing screen plate before the inferior beginning of next casting.
During concrete the application, start 11 pairs of screen plates of gas-preheating burner and carry out preheating before the casting beginning, preheating temperature is 400～800 ℃.Close fuel burner nozzle after the casting beginning, aluminium liquid is through the 1 inflow filter box that enters the mouth, and screen plate 2 and following screen plate 3 filter the back from exporting 7 outflow filter casees on the process.Temperature decline is bigger behind the strumbox if aluminium liquid is flowed through, and then the opening resistor heating system utilizes 8 pairs of aluminium liquid of resistance heating element to heat, to improve the flowability and the cavity filling ability of aluminium liquid; The processing requirement of casting can be satisfied as temperature of aluminum liquid, electric heating system can be do not opened.After casting finished, if the intensity of screen plate and filter effect can satisfy the requirement of next casting time, then aluminium liquid was not put driedly in the strumbox, starts electric heating system aluminium liquid is carried out heat tracing, and until next casting time beginning, holding temperature is between 680～760 ℃.Change screen plate as need, then after casting finishes, aluminium liquid is discharged from weif orifice 6.
In sum, the utility model structure uniqueness adopts different heating units to heat in the different steps of casting, and realizes the repeated use of screen plate, and foamed ceramic filter plate can not a reusable difficult problem when having solved the production of aluminium and aluminium alloy cast ingot D.C.casting.
What need understand is: above-mentioned explanation is not to be to restriction of the present utility model, and in the utility model design scope, the interpolation of being carried out, conversion, replacement etc. also should belong to protection domain of the present utility model.
