Description
Technical field
The utility model relates to a kind of solid sand structure, is specifically related to the die casting vacuum pouring adopted in a kind of die casting vacuum pouring system with solid sand structure.
Background technology
The quality requirement of steel ingot is more and more higher in recent years, the degree of purity that how to improve steel ingot is the problem of steelmaker author's primary study, taked various measures in smelting casting process, wherein in casting process, the cleaning drying of accessory is an important controlling unit for this reason.
Equipment in die casting vacuum pouring system comprises vacuum chamber 10, vacuum cover 1, mozzle 2, tundish 11 etc., and scheme of installation as shown in Figure 1.Vacuum cover 1 is the lid of airtight vacuum chamber 10, and mozzle 2 is cylindrical device, is used for limiting the angle of flare after molten steel pours into vacuum chamber, is arranged on the plug hole place on vacuum cover 1.After mozzle 2 is put into plug hole, there is the approximately gap of 30～50mm between mozzle and plug hole, need to fill with quartz sand, hit tight, then make its bonding with waterglass.Due to the effect of pressure differential, be easy to the floating sand that does not bond around mozzle is sucked in ingot mould through the mozzle upper entrance when vacuum chamber vacuumizes, increased the risk of steel ingot foreign impurity, have a strong impact on the steel ingot degree of purity.
Traditional processing method is to sweep and the labor cleaning with broom, can not thoroughly clean out floating sand in this way.After designed a kind of die casting vacuum pouring mozzle protection tile, build by laying bricks or stones at mozzle excircle back-up sand upper surface, by 3 kinds of brick types the combination of totally 6 bricks form a circle.The mozzle protection tile can only disposablely use, and its installation, builds, removes equal inconvenience by laying bricks or stones, simultaneously high expensive; In addition, protection tile build by laying bricks or stones complete after, unavoidably have the gap between brick and brick and between brick and mozzle, Gu the sand effect is unsatisfactory, can not well stop back-up sand to enter ingot mould.
The utility model content
Technical problem to be solved in the utility model is to provide the solid sand structure of a kind of easy-to-mount die casting vacuum pouring.
the technical scheme that its technical problem that solves the utility model adopts is: the solid sand structure of die casting vacuum pouring, comprise vacuum cover and mozzle, offer plug hole on vacuum cover, at mozzle periphery fixed cover, ring flange is housed, described mozzle passes plug hole, the lower surface of ring flange is engaged on the upper surface of vacuum cover, upper surface at vacuum cover is provided with the refractory layer that is positioned at the mozzle surrounding, be filled with the back-up sand layer between refractory layer and mozzle, be coated with protective cover at back-up sand layer upper surface, the surrounding that described protective cover sealing shroud is contained in mozzle periphery and protective cover extends to the refractory layer upper surface, described protective cover adopts flexible refractory material to make and forms.
Further that described protective cover is the torus structure.
Be further, described protective cover has internal layer with outer, and described skin is coated on outside internal layer, and described outer employing refractory fiber cloth is made and formed, and internal layer adopts fire-resistant cotton making to form.
Further that described refractory layer adopts refractory brick to make and forms.
The beneficial effects of the utility model are: make because protective cover adopts flexible refractory material, therefore its softness, light and handy is installed and used more convenient fast, also is beneficial to the rapid dismounting after casting complete, can repeatedly use, and cost is cheap than refractory brick; In addition, because it is also refractory material, can adapt to resistant to elevated temperatures requirement in the high temperature casting process; Simultaneously, also due to its soft characteristic, after its sealing shroud installs to the mozzle periphery, can there be the gap in installation process, thereby can effectively avoid floating in the vacuum chamber vacuum sand sucks in ingot mould, can greatly reduce the risk of steel ingot foreign impurity, improve the degree of purity of steel ingot, be particluarly suitable for applying in the die casting vacuum pouring.
Description of drawings
Fig. 1 is the mounting structure schematic diagram of whole die casting vacuum pouring system;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the protective cover perspective view.
Be labeled as in figure: vacuum cover 1, mozzle 2, refractory layer 3, back-up sand layer 4, protective cover 5, plug hole 6, ring flange 7, internal layer 8, skin 9, vacuum chamber 10, tundish 11.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
as shown in Figure 2 to Figure 3, the solid sand structure of die casting vacuum pouring of the present utility model, comprise vacuum cover 1 and mozzle 2, offer plug hole 6 on vacuum cover 1, at mozzle 2 periphery fixed covers, ring flange 7 is housed, described mozzle 2 passes plug hole 6, the lower surface of ring flange 7 is engaged on the upper surface of vacuum cover 1, upper surface at vacuum cover 1 is provided with the refractory layer 3 that is positioned at mozzle 2 surroundings, be filled with back-up sand layer 4 between refractory layer 3 and mozzle 2, be coated with protective cover 5 at back-up sand layer 4 upper surface, the surrounding that described protective cover 5 sealing shrouds are contained in mozzle 2 peripheries and protective cover 5 extends to refractory layer 3 upper surfaces, described protective cover 5 adopts flexible refractory material to make and forms.Make because protective cover 5 adopts flexible refractory materials, therefore its softness, light and handy is installed and used more convenient fast, also is beneficial to the rapid dismounting after casting complete, can repeatedly use, and cost is cheap than refractory brick; In addition, because it is also refractory material, can adapt to resistant to elevated temperatures requirement in the high temperature casting process; Simultaneously, also due to its soft characteristic, after its sealing shroud installs to mozzle 2 peripheries, can there be the gap in installation process, suck in ingot mould thereby can effectively avoid to float in the vacuum chamber vacuum sand, can greatly reduce the risk of steel ingot foreign impurity, improve the degree of purity of steel ingot.This protective cover 5 can select the refractory material of refractory fiber cloth, fire-resistant cotton or other softness to make, or adds the fire-resistant cotton formation protective cover 5 of making in refractory fiber cloth.
