Description
Technical field
The invention belongs to field of metal preparation, be specially adapted to a kind of non-crystal belt making float-valve type spray bag.
Background technology
In the prior art, amorphous alloy ribbon preparation uses flash set technology usually, and molten iron is poured into the chill roll surface of rotation to form strip by the spray bag being provided with nozzle.Wherein rely on the gravity type carrying device of molten iron deadweight cast in spray bag, while spray wraps in and starts to inject molten iron, spray band just starts.At this moment, due to molten iron extremely unstable in spray bag, scum silica frost is many, pressure is inadequate, and to when being full of molten iron in wrapping, need the several seconds could be gradually stable, the band before stablizing all can not reach instructions for use.Meanwhile, when artificial turndown cast, spray bag liquid level is difficult to stability contorting, 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 pouring into a mould, and in continuous spraying band process, nozzle, chill roll surface produce distortion seriously by high temperature liquid iron souring, reduce strip quality and service life of equipment.Meanwhile, the design of existing spray bag is when spraying band and extremely interrupting, and in bag, high temperature liquid iron still needs streamer voluntarily, while wasting raw material, cause potential safety hazard to equipment and operating personnel, is not easy to handling.
Summary of the invention
A kind of non-crystal belt making float-valve type is the object of the present invention is to provide to spray bag, this float-valve type spray bag can make molten iron uniform flow in spray band process, freely can control liquid level, initiatively can be interrupted spray band, when spray band can be stoped abnormal, molten iron is let out down voluntarily, and this apparatus structure is simple simultaneously, and cost is low, safe and reliable, extend the service life of equipment.
The invention provides a kind of non-crystal belt making float-valve type spray bag, adopt following technical scheme:
A kind of non-crystal belt making float-valve type spray bag, 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, water inlet seat board is fixed with water inlet, nozzle carrier is provided with in spray bag bottom, the lower end of nozzle carrier is provided with nozzle, and nozzle carrier is fixed with valve rod base, it is characterized in that: this float-valve type spray bag also comprises floating valve gear, baffle plate, two, left and right balancing weight; Described floating valve gear is located in the chamber of spray bag, and be made up of valve rod, floating block and two, left and right guide rod, 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, the upper end of two guide rods in left and right is stretched out respectively by fairlead from the hole of baffle plate and the water inlet seat board left and right sides, two balancing weights in left and right are respectively equipped with on the top of two guide rods in left and right, baffle plate is actively installed on spray and wraps in the groove of end, and baffle plate is provided with a point water cone.
In technique scheme, molten iron injects in the chamber of spray bag through water inlet, point water cone shunting on baffle plate, in the runs down both sides of baffle plate, iron level current stabilization is entered in spray bag chamber, prevents molten iron to splash and 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 to float under molten iron buoyancy, hole in the middle of valve rod base is opened, 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, the liquid level of molten iron in spray bag chamber is controlled by balancing weight, realize the liquid level free adjustment on belt making process, and this kind of control method liquid level is stablized, increase counterweight in spray band process and initiatively can stop cast, valve rod declines and float valve cuts out, and avoids molten iron to let out down voluntarily, meanwhile nozzle avoids washing away under keeping warm mode, extends nozzle service life; When spraying band situation and occurring abnormal, manually increase counterweight and float valve cuts out, avoid molten iron to flow out splashing injury device.
