Abstract
The utility model provides a flow guide pipe for casting of aluminum and aluminum alloy. The flow guide pipe for the casting of the aluminum and the aluminum alloy comprises an outer layer of the flow guide pipe, the outer layer of the flow guide pipe is of a split symmetrical structure, a connecting shaft and a movable joint compression bolt are arranged on the outer layer of the flow guide pipe in the axial direction of the flow guide pipe, and a aluminum silicate insulating layer and a clay graphite half tube are respectively arranged inside flow guide pipe. An upper pressing plate and an end pressing plate are arranged on the clay graphite half tube, and the clay is fixedly connected with the outer layer of the flow guide pipe through screws. An upper heat insulating cushion is arranged between the upper pressing plate and the clay graphite half tube, and an end heat insulating cushion is arranged between the end pressing plate and the clay graphite half tube. Due to the fact that the clay graphite half tube is made of clay graphite materials which is difficult to stick to the aluminum, adhering slags on the surface of the flow guide pipe are easy to clean, the flow guide pipe is of the split symmetrical structure, and cleaning or replacing work after guiding flow is convenient. The aluminum silicate insulating layer, the upper heat insulating cushion and the end heat insulating cushion all are made from high temperature resistant materials with zirconium, and therefore the service life and the insulating effect of the flow guide pipe are guaranteed.
Description
Technical field
The utility model belongs to field of metallurgy, relates in particular to a kind of aluminium and aluminum alloy melt casting mozzle.
Background technology
Aluminium and aluminum alloy melt casting mozzle are that supplying in aluminium and the aluminum alloy melt casting equipment flowed part.At present, be used for the moulding system of aluminium and aluminum alloy melt casting, mostly adopt the chute of open type for stream, because aluminium is exposed among the air night, thereby heat loss is large, oxidization burning loss is large, oxide slag inclusion is many, aluminium liquid easily adsorbs hydrogen that air content is increased.Though tubular type is arranged for stream because the inner-walls of duct slagging scorification and be difficult to cleaning, service life is short, use cost is too high, be not easy to the problem such as operation is difficult to actual production.
Summary of the invention
The utility model provides a kind of aluminium and aluminum alloy melt casting mozzle, has solved in the background technology chute and has reached greatly other tubular types for stream inner-walls of duct slagging scorification for the stream heat loss and be difficult to cleaning, be not easy to the shortcoming such as operation.
The technical solution of the utility model is achieved in that a kind of aluminium and aluminum alloy melt casting mozzle, comprise that mozzle is outer, mozzle is outer to be the split symmetrical structure, and it axially is respectively equipped with connecting axle and movable joint hold-down bolt, is respectively equipped with alumina silicate heat-insulation layer and clay graphite semicanal in its body;
Clay graphite semicanal is provided with top hold-down and end pressing plate, is fixedly connected with the mozzle skin by screw;
Be provided with the top heat insulating mattress between top hold-down and the clay graphite semicanal, be provided with the end heat insulating mattress between end pressing plate and the clay graphite semicanal.
The beneficial effects of the utility model are: the utility model since clay graphite semicanal for being difficult for the clay graphite material of sticking aluminium, so the easier cleaning of surperficial dross, mozzle is the split symmetrical structure, the cleaning behind each water conservancy diversion or more change jobs comparatively convenient; Alumina silicate heat-insulation layer, top heat insulating mattress, end heat insulating mattress etc. are the high temperature resistant material that contains Zirconium, thereby have guaranteed service life and the heat insulation effect of mozzle.
Description of drawings
Fig. 1 is the utility model sterogram;
Fig. 2 is the utility model entity opening figure;
Fig. 3 is the utility model assembling schematic diagram.
Part explanation: 1, mozzle shell; 2, alumina silicate heat-insulation layer; 3, clay graphite semicanal; 4, top heat insulating mattress; 5, end heat insulating mattress; 6, top hold-down; 7, end pressing plate; 8, screw; 9, movable joint hold-down bolt; 10, connecting axle.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: a kind of aluminium and aluminum alloy melt casting mozzle, comprise mozzle skin 1, mozzle outer 1 is the split symmetrical structure, it axially is respectively equipped with connecting axle 10 and movable joint hold-down bolt 9, be respectively equipped with alumina silicate heat-insulation layer 2 and clay graphite semicanal 3 in its body, clay graphite semicanal 3 is provided with top hold-down 6 and end pressing plate 7, be fixedly connected with mozzle skin 1 by screw 8, be provided with top heat insulating mattress 4 between top hold-down 6 and the clay graphite semicanal 3, be provided with end heat insulating mattress 5 between end pressing plate 7 and the clay graphite semicanal 3.
Because clay graphite semicanal is for being difficult for the clay graphite material of sticking aluminium, so easier cleaning of surperficial dross, mozzle is comprised of two lobes, cleaning behind each water conservancy diversion or more change jobs comparatively convenient, alumina silicate heat-insulation layer, top heat insulating mattress, end heat insulating mattress etc. are the high temperature resistant material that contains Zirconium, thereby have guaranteed service life and the heat insulation effect of mozzle.
