Abstract
The utility model provides a launder for the fusion casting of aluminum and aluminum alloy, which comprises an outer launder shell and an inner launder shell; a refractory lining material layer is arranged in the inner launder shell; a cavity is formed between the outer launder shell and the inner launder shell, and the outer launder shell and the inner launder shell are connected together by screws; the inner launder shell is full of air holes; and the refractory lining material layer is alumina-silicate ceramic fibre soaked with silicasol, on which boron nitride coating is sprayed. The sizeand weight of the launder are reduced, the time of fabricating and baking the launder is shortened, the heat-preserving effect of the launder is enhanced, and the quality of castings is improved.
Description
Technical field
The utility model belongs to field of metallurgy, relates in particular to a kind of aluminium and aluminum alloy melt casting chute.
Background technology
The founding chute is that supplying in aluminium and the aluminum alloy melt casting equipment flowed part.At present, be used for the chute of aluminium and aluminum alloy melt casting, generally form by iron-clad, asbestos heat-insulation layer, the cast bed of material.Volume is big, and weight is big, and heat insulation effect is undesirable.Since with aluminium liquid contact layer for watering material feeding, its caloric receptivity is big, needs preheating time long, and making, toast all more loaded down with trivial details.Simultaneously, because insulation is relatively poor, aluminium liquid thermal loss is big, is unfavorable for energy-conservation and the raising casting quality.
Summary of the invention
The utility model provides a kind of aluminium and aluminum alloy melt casting chute, has solved chute volume in the background technology, weight is big, and shortcoming such as heat insulation effect is bad, the caloric receptivity big, preheating time is long.
The technical solution of the utility model is achieved in that a kind of aluminium and aluminum alloy melt casting chute, comprises the chute shell, and the chute inner casing is established the refractory lining bed of material in the chute inner casing;
Be hollow between chute shell and the chute inner casing, the chute shell is connected by screw with the chute inner casing;
Be covered with air-vent on the chute inner casing;
The described refractory lining bed of material is that alumina-silicate ceramic fibre soaks Ludox, the spraying boron nitride coating.
The beneficial effects of the utility model are: the utility model has reduced the chute volume, has alleviated chute weight, has shortened chute and has made and stoving time, has improved the heat insulation effect of chute, has improved casting quality.
Description of drawings:
Fig. 1 is the chute schematic perspective view;
Fig. 2 is not for doing the assembling schematic perspective view of chute shell and chute inner casing before the refractory lining.
Part explanation: 1, chute shell; 2, chute inner casing; 3, the refractory lining bed of material; 4, air-vent; 5, screw.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: a kind of aluminium and aluminum alloy melt casting chute, comprise chute shell 1, chute inner casing 2, establish the refractory lining bed of material 3 in the chute inner casing 2, this wadding caloric receptivity is very little, heat insulation effect is good, and be convenient to maintenance, be covered with air-vent 4 on the chute inner casing 2, make refractory lining be more conducive to drying and adhere to, groove shell 1 is connected by screw 5 with chute inner casing 2, be convenient to maintenance and replacing, be hollow between chute shell 1 and the chute inner casing 2, both alleviated weight, improved heat insulation effect again.
Claims (4)
1, a kind of aluminium and aluminum alloy melt casting chute comprise chute shell (1), and chute inner casing (2) is characterized in that establishing in the chute inner casing (2) the refractory lining bed of material (3).
2, a kind of aluminium according to claim 1 and aluminum alloy melt casting chute is characterized in that being hollow between chute shell (1) and the chute inner casing (2) that chute shell (1) is connected by screw (5) with chute inner casing (2).
3, a kind of aluminium according to claim 1 and 2 and aluminum alloy melt casting chute is characterized in that being covered with on the chute inner casing (2) air-vent (4).
4, a kind of aluminium according to claim 1 and 2 and aluminum alloy melt casting chute is characterized in that the described refractory lining bed of material (3) for alumina-silicate ceramic fibre soaks Ludox, the spraying boron nitride coating.
