Abstract
The utility model relates to a crucible skim gate for an overflow-type vacuum melt fast quenching spinning furnace, including a crucible gate of which the upper part is fixed with a slag back plate. The height of the opening formed between the bottom surface of the slag back plate and outlet surface of the crucible gate is 5mm-10mm. The utility model has the function of slag stopping, which can both prolong the service life of the overflow-type vacuum melt fast quenching spinning furnace and improve the quality of the fast-quenching product.
Description
Technical field
The utility model relates to a kind of overflow-type vacuum melting quick quenching furnace crucible cast gate, particularly a kind of overflow-type vacuum melting quick quenching furnace crucible skim gate.
Background technology
Overflow-type vacuum melting quick quenching furnace is mainly used in amorphous and nanocrystalline material, existing overflow-type vacuum melting quick quenching furnace charges into the 0.04MPa argon gas after vacuumizing, carry out melting then, metal is the non-consumable electric arc melting in cold-crucible, metal liquid constantly overflows on the crucible cast gate, run into atwirl copper roller, fast quenching becomes the amorphous thin slice, and its principle schematic is seen Fig. 1.Owing to reach several hours work, the sealing of melting quick quenching furnace high speed rotational workpieces goes wrong unavoidably, causes big gas leakage, so that in the molten bath slag appears, the melting quick quenching furnace crucible cast gate if slag is flowed through, run into atwirl copper roller (20～30m/s), can cause the damage on copper roller surface.In addition, slag is sneaked into and also can be caused the fast quenching properties of product to descend in the fast quenching thin slice.
The utility model content
The purpose of this utility model is to provide a kind of overflow-type vacuum melting quick quenching furnace crucible skim gate, has the pushing off the slag function, can increase copper roller service life, can improve the quality of fast quenching product again.
For achieving the above object, the utility model adopts following technical proposals:
A kind of overflow-type vacuum melting quick quenching furnace crucible skim gate comprises the crucible cast gate, it is characterized in that the fixedly connected slag trap in crucible cast gate top, and the open height that forms between slag trap bottom surface and the crucible cast gate exit face is the 5-10 millimeter.
Above-mentioned crucible cast gate and the fixed connection structure between the slag trap are: crucible cast gate outlet both sides are fluted to be complementary with two ends slag trap and to rabbet, and its seam crossing is filled the baking and curing combination by fire clay and waterglass.
During the quick-quenching Nd-Fe-B permanent-magnet material, the open height that forms between slag trap bottom surface and the crucible cast gate exit face is the 6-8 millimeter.
The utility model compared with prior art, have following conspicuous characteristics and advantage: the utility model is provided with slag trap, can block slag, make it not flow to atwirl copper roller, both prevented the damage on copper roller surface, prolong the service life of copper roller, improved the product quality of fast quenching thin strap again.

Fig. 2 is example structure schematic diagram of the utility model.
Fig. 3 is the schematic perspective view of crucible cast gate in Fig. 2 example.
Fig. 4 is the schematic perspective view of slag trap in Fig. 2 example.
The specific embodiment
A preferred embodiment of the present utility model is: referring to Fig. 1, the structure of overflow-type vacuum melting quick quenching furnace is: settle copper roller rotating 5 in vacuum furnace body 6, settle crucible 1 near copper roller 5, its crucible cast gate 4 is near the outer rim of copper roller 5, plant electrode 3 in the crucible 1, there is hopper 2 crucible 1 top.Referring to Fig. 2, Fig. 3 and Fig. 4, this overflow-type vacuum melting quick quenching furnace crucible skim gate includes crucible cast gate 4, the fixedly connected slag trap 7 in crucible cast gate 4 tops, the open height that forms between slag trap 7 bottom surfaces and crucible cast gate 4 exit faces is the 5-10 millimeter, when the quick-quenching Nd-Fe-B permanent-magnet material, the open height that forms between slag trap 7 bottom surfaces and crucible cast gate 4 exit faces is the 6-8 millimeter.Fixed connection structure between crucible cast gate 4 and the slag trap 7 is: the two ends of crucible cast gate 4 outlet both sides fluted 8 and slag trap 7 are complementary and rabbet, and its seam crossing is filled the baking and curing combination by fire clay and waterglass.
