Description
Technical field
The present invention relates to be used to make the system carrying device of non-crystaline amorphous metal or amorphous and nanocrystalline soft magnetic alloy, particularly liquid level pressure amorphous pocket builder such as a kind of plunger type.
Background technology
Invented from nineteen sixty U.S. professor guwez that (cooling velocity is 10 with rapid quenching technique
6℃/s) since the preparation Au-Si series amorphous alloy, because its institutional framework, preparation technology, excellent material property receive the special concern of Material Physics scholar and industrial circle efficiently always.U.S. Allied-Signal company developed non-crystaline amorphous metal broadband fast quenching technology in 1979, made the big production of amorphous alloy strips become possibility.U.S. Allied-Signal company had possessed the production capacity that annual production reaches 60,000 tons of amorphous ribbons in 1989, and wherein representing the trade mark is 2605S-2, and composition is Fe78Si9B13.Present domestic annual requirement reaches 100,000 tons and goes up.
The Ji Zeke benevolence of FDAC metal Co., Ltd. in 1988 has been researched and developed the magnetically soft alloy of high magnetic conducting nanocrystalline grain, and typical composition is Fe73.5Cu1Nb3Si13.5B9.Present domestic annual production can reach more than the 5000t.
The amorphous nano peritectic alloy is just led excellent properties such as high-saturation magnetic induction, low-coercivity low-loss because of having height, becomes outstanding person in the market.But along with the development of electron electric power product, particularly range transformer have proposed high request with iron core aspect the loss.The formula of estimation eddy-current loss is on engineering:
Pe∝kδ
2/ρ
δ is the thickness of material in the formula, and ρ is the resistivity of material
The effective way that for this reason reduces eddy-current loss is the thickness that lowers material.So carried out the technology and the equipment of research and development spray amorphous nano-crystalline strip in recent years both at home and abroad, this spray band machine is commonly referred to as pressure spray band machine.
The production technology that the amorphous and nanocrystalline soft magnetic alloy band is general is: adopt vaccum sensitive stove or non-vacuum induction furnace to smelt the foundry alloy of amorphous nano-crystalline; Again through the non-vacuum induction furnace remelting, the nozzle bag through spray band machine is sprayed onto processes amorphous ribbon on the chill roll with foundry alloy.Common amorphous ribbon pocket builder is divided into two kinds usually, and two bag methods and three guarantees method are like Fig. 1,2.Among Fig. 1 11 is that non-vacuum induction furnace 12 is the nozzle bags that install nozzle additional; The nozzle bag adopts the resistance wire heating to play insulation effect; The induction furnace induced field injects in the nozzle bag when making molten steel temperature reach uniform temperature; Molten steel injects chill roll ejection amorphous ribbon through nozzle by the deadweight of molten steel, because the not high amorphous ribbon that can only produce greater than 30um of liquid level.Fig. 2 is the common spray band machine of three guarantees method; 21 is that non-vacuum induction furnace, 22 is that tundish, 23 is to be the globar heating resistor by the molten steel, 25 that induction furnace injects; Owing to adopt the globar heat tracing higher; Owing to adopt tundish, molten steel to make impurity come-up, favourable raising steel band quality at Bao Zhongke.
The spray band pressure of common spray band machine is to lean on the molten steel deadweight in the nozzle bag to produce.General liquid level height is about 200mm, the about 0.15kg/cm of the pressure of generation
2. the amorphous ribbon thickness average out to 33 μ m of spray, the mouth seam of nozzle is wide to be 0.7-0.8mm, the about 0.1mm of distance of nozzle and chill roll, for pressure, the induction furnace that keeps spraying band will constantly inject molten steel in the spray bag, usually each injection rate is 5-8kg.
Domestic a large amount of amorphous ribbon is all accomplished by common pocket builder at present.And the annual production of amorphous strip is no more than 400t.
The pressure of research and development sprays band machine such as Fig. 3,4,5,6 both at home and abroad.
Fig. 3: 31 are chill roll for heating rod, 37 for stopper rod, 36 for induction coil, 35 for the crucible of refractory material system, 34 for the gas interface, 33 of exerting pressure for peep hole, 32.Add foundry alloy in the crucible earlier during work, sealing, eddy-current heating when the foundry alloy fusing reaches temperature, draws back stopper rod and makes molten steel flow to chill roll spray band.
Fig. 3 is a Russian non-crystaline amorphous metal pressure spray band machine, and the nozzle bag of this machine seal, in the process of spray band is to rely on constantly the pressure of increase inert gas to keep spraying the pressure of band.But the band amount of unit interval ejection is difficult for tolerance, so follow the tracks of the force value of regulating inert gas certain degree of difficulty is arranged.This equipment foundry alloy melts through eddy-current heating in the nozzle bag.The magnetic field of induction can cause the metal material of nozzle bag support section because magnetic hysteresis is flexible size possibly to be changed, so the distance of nozzle and chill roll can be affected, so also just influenced the uniformity of the amorphous ribbon thickness that spray goes out.This pocket builder fixed nozzle position and stopper rod are all processed with meticulous graphite, and every spray one furnace zone, this part just needs to change once, so expense is bigger.This spray band machine can not be added molten steel in the nozzle bag in spray band process in addition, so the spray band amount of a stove has limitation.
Among Fig. 4: 41 for exert pressure pipeline, 47 for eddy-current heating induction coil, 48 for vacuum drying oven body of heater, 49 are crucible, 410 molten steel for pack foundry alloy fusing for quartz ampoule, 46 for quartzy nozzle, the 43 telescopic bellowss for sealing are used to adjust roll gap, 44 for vacuum lead, 45 for chill roll, 42; Foundry alloy is packed in the crucible during work; Sealing; Eddy-current heating, when molten steel temperature reached, the molten steel of exerting pressure sprayed to chill roll spray band from quartz ampoule.
Fig. 4 is the sketch map of German amorphous pressure pocket builder.This equipment was just introduced by China Shanxi as far back as 2002.But off-duty still at present.Beijing company in 2009 has also introduced should technology, but equipment is also in debugging.
The characteristics of this machine are following sprays, are with on chill roll cornerite big in theory, good cooling results.Be convenient to set up tension force if adopt the take-up of automatic band-retracting machine.Because foundry alloy is remelting under vacuum, degassing effect is good.
This equipment is found in debugging, because foundry alloy adopts the eddy-current heating remelting, the distance of nozzle and chill roll is difficult to stable, and is the same with Fig. 3.Owing to adopt spray down, crucible must insert the conduit (generally using quartz ampoule) of band nozzle in addition, in stove, exerts pressure during the spray band, makes molten steel in managing, spray to chill roll.Quartz ampoule bursts and happens occasionally in the use.Because of being difficult for temperature raising, nozzle exists the problem that when band spray gags somebody or belt surface is bad.This equipment manufacturing cost is high in addition, consumes greatly, and operating difficulties also is an objective reality.
Fig. 5 is melted foundry alloy by non-vacuum induction furnace; When temperature reaches; Logical burned steel mouth 51 injects in the nozzle bag 56, and by mobile stopper rod 511, molten steel arrives chill roll through the mouth of a river 57 through nozzle 59 and realizes the spray band; Wherein globar 55 is heating and heat preserving functions, the pressure of spray band by the molten steel height with apply air pressure and form.
Fig. 5 is the electric resistor heating type pressure spray band machine of Beijing research and development, and this machine is the domestic amorphous thin ribbon pocket builder that has formed industrialization, when this machine reaches uniform temperature by non-vacuum induction furnace remelting foundry alloy, is injected into molten steel in the nozzle bag, the sealed-in nozzles bag again.Exert pressure with inert gas during the spray band, promote stopper rod, regulate roll gap spray band.But owing to adopt gas pressure spray band, the nozzle bag seals, and in the process of spray band, can not add molten steel, so every stove spray band amount is limited.
Fig. 6: 61 is that peep hole, 62 is chill roll for stopper rod, 610 for nozzle, 69 for the pallets that move the nozzle bag, 68 for induction coil, 67 for nozzle bag graphite part, 66 for the carbon silicon of nozzle bag part, 65 for nozzle bag, 64 for capstan, 63; Putting into the nozzle bag to foundry alloy during work seals; Feed argon gas by forcing pipe,, use electromagnetic induction heating induction coil 66 energisings; By the pallet that moves the nozzle bag 67 adjustment roll gap is the distance of nozzle and chill roll; When temperature reached, pulling stopper rod 69 spray bands were adjusted air pressure along with molten steel descends.
Fig. 6 is a kind of amorphous pressure pocket builder of domestic research and development.This machine is similar with the pressure spray band machine of Russia design on the principle, and the nozzle bag of this machine adopts graphite and carborundum two bodies formation.Because the molten steel contact site is made up of graphite, molten steel is bigger to the corrosion of graphite, in molten steel, can pollute molten steel and a large amount of carbon is molten, influences the magnetic property of amorphous ribbon.Since in the nozzle bag, adopt eddy-current heating remelting foundry alloy, thus also exist roll gap gap problem of unstable, at present should technology prematurity still.
