Evenly be provided with several taper holes along hoop in the described top board, the top that taper hole is arranged on the lower surface of top board and taper hole does not penetrate the upper surface of top board.
Described top board is carborundum plate.
Syndeton between described push pipe and the spray bag is: the outside of push pipe is disposed with shock ring and retainer ring from top to bottom, the top of shock ring is provided with graphite gasket, be provided with beam between shock ring and the retainer ring, retainer ring is wrapped end face by screw and spray and is fixed.
Syndeton between described sealing flange and the crucible is: sealing flange has a cylindrical tube and flange circle to consist of, be provided with carbon seal ring between the bottom of flange circle and crucible, the below of flange circle is provided with mounting flange, be provided with heat insulation foam between mounting flange and the flange circle, fix by screw between mounting flange and the crucible.
Be provided with four cylinders on the described frame, the motion bar of four cylinders connects respectively four edges of crucible.
The invention has the beneficial effects as follows: the feeding device in the above-mentioned amorphous strip maker, it is simple in structure, easy and simple to handle, its mode by the bursting top board realizes the molten steel conveying between crucible and the spray bag, during the thawing steel flow out to molten steel from nozzle, whole process belongs to sealing state, molten steel can not contact with extraneous air, and is oxidized thereby molten steel is difficult for, thereby can control better the quality of prepared amorphous ribbon.

The specific embodiment
Below by specific embodiment the feeding device in the amorphous strip maker of the present invention is described in further detail.
As shown in Figure 1, feeding device in the amorphous strip maker, comprise frame 1, be fixed with spray bag 2 on the frame 1, the top of described spray bag 2 is provided with push pipe 3, the top of push pipe 3 is pyramidal structure, be provided with crucible 4 moving up and down directly over the spray bag 2, the top open part of crucible 4 is provided with seal cover 5, be provided with gas-adding pipe 6 in the seal cover 5, the bottom opening place of crucible 4 is provided with sealing flange 7, is provided with top board 8 in the flange hole of sealing flange 7, top board 8 is bonded in the top of sealing flange 7 by high temperature resistant glue, top board 8 be positioned at push pipe 3 directly over.
Such as Fig. 2, shown in Figure 3, evenly be provided with several taper holes 9 along hoop in the described top board 8, the top that taper hole 9 is arranged on the lower surface of top board 8 and taper hole 9 does not penetrate the upper surface of top board 8.
Described top board 8 is carborundum plate.
As shown in Figure 4, syndeton between described push pipe 3 and the spray bag 2 is: the outside of push pipe 3 is disposed with shock ring 10 and retainer ring 11 from top to bottom, the top of shock ring 10 is provided with graphite gasket 12, be provided with beam 13 between shock ring 10 and the retainer ring 11, retainer ring 11 fixes by screw and spray bag 2 upper surfaces.
As shown in Figure 5, syndeton between described sealing flange 7 and the crucible 4 is: sealing flange 7 has a cylindrical tube 14 and flange circle 15 to consist of, be provided with carbon seal ring 16 between the bottom of flange circle 15 and crucible 4, the below of flange circle 15 is provided with mounting flange 17, be provided with heat insulation foam 18 between mounting flange 17 and the flange circle 15, fix by screw between mounting flange 17 and the crucible 4.Realize being tightly connected between sealing flange 7 and the crucible 4 by carbon seal ring 16.
The motion bar that is provided with 19, four cylinders 19 of four cylinders on the described frame 1 connects respectively four edges of crucible 4.
Operation principle of the present invention is: after crucible 4 melts steel, motion bar by cylinder 19 shrinks, so that crucible 4 integral body move down certain distance, along with moving down of crucible 4, the upper end of push pipe 3 contacts with top board 8, owing to evenly being provided with several taper holes 9 along hoop in the top board 8, push pipe 3 can be worn top board 8 tops, top board 8 floats up to the molten steel top, along with wear on the top of top board 8 because proportion is lighter in the molten steel of melting, molten steel in the crucible 4 enters in the spray bag 2, and flow downward, realize the system band, in band process processed, change according to the pressure in the crucible 4, from gas-adding pipe 6, in crucible 4, add inert gas, so that the maintenance of the pressure in the crucible 4 is constant, thereby guarantee the quality of prepared amorphous ribbon.In the above-mentioned course of work, when crucible 4 moved down, the bottom of sealing flange 7 contacted with the graphite gasket 12 of push pipe 3 external vibration-absorbing rings 10 tops, thereby can prevent the leakage of molten steel, and realize damping by beam 13, avoid spraying bag 2 vibration downwards under the effect of impulsive force.After the system band is finished, can change top board 8, only need sealing flange 7 is taken off from crucible 4, the residual fraction of top board 8 is removed, the new top board 8 that then again bonds just can reuse.
The invention has the beneficial effects as follows: the feeding device in the above-mentioned amorphous strip maker, it is simple in structure, easy and simple to handle, its mode by bursting top board 8 realizes the molten steel conveying between crucible 4 and the spray bag 2, during the thawing steel flow out to molten steel from nozzle, whole process belongs to sealing state, molten steel can not contact with extraneous air, and is oxidized thereby molten steel is difficult for, thereby can control better the quality of prepared amorphous ribbon.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the present invention; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
