Background technology
In the prior art, flash set technology is used in amorphous alloy ribbon preparation conventionally, molten iron by the chill roll surface that the spray bag of nozzle is installed is poured into rotation to form strip.The gravity type carrying device processed that wherein relies on molten iron deadweight cast in spray bag, spray wraps in when starting to inject molten iron, and spray band just starts.At this moment, because molten iron in spray bag is extremely unstable, scum silica frost is many, pressure is inadequate, when being full of molten iron in wrapping, needs the several seconds could be gradually stable, and the band before stablizing all can not reach instructions for use.Meanwhile, when artificial turndown cast, spray bag liquid level is difficult to stable control, and automatic liquid level controlling system is complicated, cost is high.
In existing spray band process, the molten iron in spray bag cannot initiatively stop cast, and it is serious that in continuous spraying band process, nozzle, chill roll surface are subject to high temperature liquid iron souring generation distortion, reduced strip quality and service life of equipment.Meanwhile, existing spray bag design is when the abnormal interruption of spray band, and in bag, high temperature liquid iron still needs streamer voluntarily, when wasting raw material, to equipment and operating personnel, causes potential safety hazard, is not easy to handling.
Summary of the invention
The purpose of this utility model is to provide float-valve type spray bag for a kind of non-crystal belt making, this float-valve type spray bag can make molten iron uniform flow in spray band process, can freely control liquid level, can initiatively be interrupted spray band, can stop spray to be with molten iron when abnormal to let out down voluntarily, this apparatus structure is simple simultaneously, and cost is low, safe and reliable, extended service life of equipment.
The utility model provides float-valve type spray bag for a kind of non-crystal belt making, adopts following technical scheme:
Float-valve type spray bag for a kind of non-crystal belt making, comprise spray bag, water inlet, water inlet seat board, nozzle and nozzle carrier, described water inlet seat board is located at the upper end of spray bag, on water inlet seat board, be fixed with water inlet, in spray bag bottom, be provided with nozzle carrier, the lower end of nozzle carrier is provided with nozzle, is fixed with valve rod base on nozzle carrier, it is characterized in that: this float-valve type spray bag also comprises floating valve gear, baffle plate, two of left and right balancing weight; Described floating valve gear is located in the chamber of spray bag, valve rod, floating block and two of left and right guide rod, consists of, and the upper end of valve rod is fixedly connected with the bottom surface of floating block, and the lower end of valve rod engages with the hole centering in the middle of valve rod base; The lower end of two guide rods in described left and right is separately fixed at the left and right sides of floating block upper end, stretch out respectively by fairlead from the hole of baffle plate and the water inlet seat board left and right sides upper end of two guide rods in left and right, in left and right, the top of two guide rods is respectively equipped with two balancing weights in left and right, baffle plate is actively installed on spray and wraps in the groove of end, and a minute water cone is installed on baffle plate.
In technique scheme, molten iron is in water inlet injects the chamber of spray bag, and minute water cone shunting on baffle plate, in the runs down both sides of baffle plate, enters in spray bag chamber iron level current stabilization, has prevented from that molten iron from splashing to occur splashings and have slagging-off effect; When in spray bag, molten iron liquid level reaches setting height, floating block is with ovable valve stem floating under molten iron buoyancy, open in hole in the middle of valve rod base, molten iron starts flow nozzle and pours into a mould, when molten iron liquid level is not enough, floating block sinks the lower end of valve rod is engaged with valve rod base interstitial hole centering, and valve rod base and valve rod are bonded with each other with bulb, realize center automatic centering, sealing is reliable; In the technical program, by balancing weight, control the liquid level of molten iron in spray bag chamber, realize the liquid level free adjustment on belt making process, and this kind of control method liquid level is stable, in spray band process, increase counterweight and can initiatively stop cast, valve rod declines float valve cuts out, and avoids molten iron to let out down voluntarily, meanwhile nozzle avoids washing away under keeping warm mode, has extended nozzle service life; When abnormal, manually increase counterweight float valve cuts out appears in spray band situation, avoid molten iron to flow out the damage equipment that splashes.
Accompanying drawing explanation
Fig. 1 is the structural representation of float-valve type spray bag for a kind of non-crystal belt making of the utility model;
Fig. 2 is the structural representation that when floating valve gear floats in the present embodiment, for a kind of non-crystal belt making, float-valve type spray is wrapped.
The specific embodiment
Below in conjunction with accompanying drawing, a kind of non-crystal belt making of the utility model is described in further detail with float-valve type spray bag.
From Fig. 1, figure, a kind of non-crystal belt making of the present embodiment is comprised of spray bag 1, water inlet 2, water inlet seat board 3, nozzle 4 and nozzle carrier 5, valve rod base 6, floating valve gear, baffle plate 7, two of left and right balancing weight 8 with float-valve type spray bag, water inlet seat board 3 is fixedly located at the upper end of spray bag 1, on water inlet seat board 3, be fixed with water inlet 2, in spray bag 1 bottom, be provided with nozzle carrier 5, the lower end of nozzle carrier 5 is provided with nozzle 4, is fixed with valve rod base 6 on nozzle carrier 5.Floating valve gear is located in the chamber of spray bag 1, by valve rod 9, two guide rods in floating block 10 and left and right 11 form, the upper end of valve rod 9 is fixedly connected with the bottom surface of floating block 10, the lower end of valve rod 9 engages with the hole centering in the middle of valve rod base 6, the lower end of two guide rods 11 in left and right is separately fixed at the left and right sides of floating block 10 upper ends, stretch out respectively by fairlead 12 from the hole of baffle plate 7 and water inlet seat board 3 left and right sides upper end of two guide rods 11 in left and right, in left and right, the top of two guide rods 11 is respectively equipped with two balancing weights 8 in left and right, baffle plate 7 is actively installed in the groove of spray bag 1 upper end, a minute water cone 13 is installed on baffle plate 7.
