Description
Technical field
The present invention relates to metal bath process field, particularly to a kind of ultrasonic emitting bar, use this to launch the ultrasonic equipment of bar and using method thereof.
Background technology
As far back as eighties of last century, it has been discovered that utilize the cavitation effect of ultrasound wave, crystal grain when motlten metal can be made to solidify is more tiny, air content is lower, it is thus achieved that more excellent cast structure.But, owing to some key technology achieves no breakthrough, ultrasound wave processes so far still without obtaining industrialization promotion for metal bath, and is only limitted to laboratory applications.One of the most unsolved key technology is exactly ultrasonic emitting bar life problems under high-temperature metal melt corrosion and ultrasonic cavitation corrosiveness.
During using ultrasonic equipment that metal bath is processed, it is generally required to one end of ultrasonic emitting bar is immersed in metal bath, thus emit ultrasonic acoustic waves in metal bath.In the prior art, this transmitting bar is typically made by metal, such as rustless steel, titanium alloy etc..
But, this transmitting bar is undesirable.This is because, the chemical property of high-temperature metal melt is relatively more active, can react with most metals, generates intermetallic compound, and the transmitting bar making metal produces corrosion until all dissolving.Such as, use ultrasonic Treatment aluminium alloy melt, the chemical property of aluminum melt is the most active, can be with almost all of metal, react such as ferrum, copper, manganese, magnesium, chromium, zinc, titanium etc., form various intermetallic compound, make these metals just be added in aluminum melt (see the phasor of the various metals such as aluminum and titanium) under far below its melting temperature.In like manner, copper alloy melt also can generate intermetallic compound with most metal generation chemical reactions.If making of these metals and launching bar, then can gradually dissolve until disappearing.Test shows, the transmitting bar that common iron makes when carrying out ultrasonic Treatment in the aluminum melt of 685 ± 10 DEG C, work 2 hours, and this transmitting bar is it would appear that obvious etch pit.Therefore, the transmitting bar that this metal makes is not to be suitable for industrialization quantity-produced, such as continuously casting or casting non-stop-machine continuous production in one month.
It is noted that patent (patent No.: CN 102554195A) discloses a kind of tantalum makes the method launching bar.Although there is not chemical reaction with most metal baths (such as aluminum melt) in tantalum, but, on the one hand, tantalum ratio is sparser, price；On the other hand, tantalum, under aerobic environment, aoxidizes when 300 DEG C, the fierceness oxidation when 550 DEG C, generates powdered oxide.Therefore, the transmitting bar made of tantalum is only applicable under vacuum environment.
For solving to launch bar etching problem in metal bath, people devise again and another kind of launch bar, i.e. outside metallic matrix, be coated with one layer resistant to elevated temperatures not with the ceramic masses of metal bath generation chemical reaction, this coating layer thickness is 0.15-4.5mm, successfully solves this problem.But, also have another kind of etching problem not solve, i.e. ultrasonic cavitation corrosion.Introducing according to patent (patent No.: CN 201713563 U), this kind of transmitting bar uses heat spraying method to make, and after various ceramic masses are fused on thermal spraying apparatus semisolid or molten state, high-velocity spray is on metallic matrix.According to data introduction, the clad that various different heat spraying methods obtain, 50MPa to 90MPa is typically only had with metallic matrix high bond strength at normal temperatures, when this transmitting bar works in high-temperature fusant, high because launching bar temperature, the bond strength of clad and metallic matrix is by rapid decrease.And when launching bar work, dither will be produced, and to launch bar each microcosmic particle near its equilbrium position, all make the of reciprocating vibration of fierceness, this vibration has the biggest acceleration.According to Newton's law F=ma, particle to keep this of reciprocating vibration, it is necessary to has a power the biggest, such as, Binding Forces Between Atoms.On the one hand being the reduction of clad and metallic matrix bond strength, be on the other hand that the power needed for microcosmic particle vibration is very big, the two coefficient results of aspect are exactly that clad comes off from metallic matrix, and this is confirmed the most in test.In theory, this main cause that comes off is clad and the bond strength deficiency of metallic matrix causes.According to data introduction, thermal spraying clad has three kinds with the combining form of metallic matrix: mechanical bond, physical bond, metallurgical binding.The adhesion of first two combination is the lowest, and the bond strength of metallurgical binding is the highest, but various spray form is all main based on mechanical bond, and metallurgical binding is little, so bond strength is the highest.Additionally, there is a lot of hole inside clad, porosity typically more than 5%, even up to 20%.When occurring stress to concentrate, these holes will become formation of crack, and extension causes clad to come off rapidly.
Holding caducous problem for clad, people devise again another kind of transmitting bar (patent No.: CN 201305623Y), i.e. outside metallic matrix, are coated with one layer of ceramic layer, and ceramic layer thickness is less than or equal to 200um.In terms of actual effect, such improvement has certain effect, but still can not tackle the problem at its root.This coating no doubt avoids the problem come off because of vibration, but the thinnest, and service life is short, and protective effect is little.Such as from the angle of raising hardness, because the thinnest, easily pierced through by hard thing；From antiseptical angle, also in that the thinnest, quickly will lose efficacy.
Therefore, ultrasonic emitting bar of the prior art can not solve metal bath corrosion and the problem of ultrasonic cavitation corrosion well.
Summary of the invention
It is an object of the invention to provide a kind of corrosion resistant ultrasonic emitting bar, it can solve the problem that metal bath corrosion and the problem of ultrasonic cavitation corrosion, solves these people and wants to solve but the problem that fails all the time always.
To achieve these goals, the invention provides a kind of corrosion resistant ultrasonic emitting bar, it is characterised in that this transmitting bar is made up of glass, the softening point temperature of glass and/or strain point temperature higher than the temperature of metal bath, and this glass not with metal bath generation chemical reaction.The glass of suitable species according to the temperature of metal bath and chemical property, can be selected, make the transmitting bar being made up of this glass normally to work in metal bath for a long time.Such as, for fusant, can select quartz glass, the softening point of quartz glass, more than 1600 DEG C, higher than fusant temperature (typically at about 1400 DEG C), and does not reacts with fusant；For aluminum melt, can be with aluminium silica glass, the softening point of aluminosilicate glass, at about 900 DEG C, higher than aluminum melt temperature (typically between 680-750 DEG C), and does not reacts with aluminum melt.The rest may be inferred by analogy for it.
Temperature according to metal bath and chemical property, select the glass with suitable softening point, strain point and chemical property.Preferably, this glass can be devitrified glass, alumina silicate glass, glass-ceramic, high-boron-silicon glass, high lead glass, optical glass, blue cobalt glass, laser safety glass, electric welding cover plate, fireproof glass, heat resistant glass, high pressure resistant glass, high temperature high voltage resistant glass or other kinds of glass.
Preferably, metal bath can be aluminium alloy melt, ferroalloy melt, copper alloy melt, signal bronze melt, FeMn68Si18 melt or other kinds of metal bath.
Preferably, launch the place that bar is acted on, can be the front case of continuous casting and rolling production line and continuous casting and rolling production line or/and lip, it can be the running channel etc. of the mould of the crystallizer of semi-continuous casting production line, casting parts, this type of position is close to solid-liquid crystallization front, introduce ultrasound wave herein, can preferably play ul-trasonic irradiation, crystal grain thinning.Further, it is also possible to be holding furnace, chute, Rose Box outlet etc., this type of position from solid-liquid crystallization front farther out, introduces ultrasound wave herein, acts primarily as the effects such as degasification.
Further, this transmitting bar can be arbitrary shape or the combination of any number of shape, and its cross section can be the combination of one or more shape of square, circular, arc, the shape such as trapezoidal, unformed, as shown in Figures 1 to 9, its size can be from 1mm to 5000mm, to adapt to various application scenario.Such as, the transmitting bar of shape shown in Fig. 1, it is adaptable to the operating mode that melt volume is the biggest, such as front case；And the transmitting bar of shape shown in Fig. 6, it is adaptable to the operating mode that melt volume is bigger, such as holding furnace etc..For adapting to some application scenario, the transmitting bar needs in ultrasonic equipment are designed to the longest very greatly.Such as, holding furnace applies ultrasound wave.Because use temperature is had strict demand, too high temperature that piezoelectric ceramics will be made to lose efficacy, therefore, it is impossible to put in holding furnace by whole ultrasonic equipment, it is necessary to ultrasonic transducer and power supply are placed in outside holding furnace by piezoelectric ceramics.And holding furnace is generally large, now, it is necessary to transmitting bar is designed to the longest very greatly, outside holding furnace, enters into through furnace wall inside holding furnace, reconnect and launch bar.Thus, the cross section launching bar of this ultrasonic equipment and longitudinal section size range are 1mm to 5000mm.
Uneven splintering problem is caused because being heated, on the one hand, can select the glass of suitable species, this glass has less linear expansion coefficient, to make it have higher heat shock resistance temperature in order to solve glass.Such as, high-boron-silicon glass can be with the temperature difference drastic change of resistance to 200 DEG C, and aluminosilicate glass can be with the temperature difference drastic change etc. of resistance to 250 DEG C to 300 DEG C.The thermal coefficient of expansion of quartz glass is little, is 5.5 × 10-7/ DEG C, only the 1/12～1/20 of simple glass.Standard regulation is thrown in cold water rapidly by after sample calcination to 1200 DEG C, does not allows to burst above repeatedly for three times.Quartz glass also can make the material of zero thermal expansion coefficient after adding appropriate titanium elements.On the other hand, technology ensuring can be passed through, first Preheat glass, it is to avoid glass drastically by thermal fracture, same Slow cooling during cooling.
In order to solve, during launching the ultrasound wave that bar is concentrated at conduction energy, power is the biggest, glass fragmentation faced problem occurs, can process solve by glass being carried out tempering or half tempered.After glass tempering or half tempered, its impact strength is more than the several times before tempering.To being difficult to tempering or the glass of half tempered process, can suitably increase transmitting bar cross-sectional area, reduce the intensity of ultrasonic energy, also have certain effect.
The invention provides a kind of ultrasonic equipment, including ultrasonic power, ultrasonic transducer, horn, transmitting bar, it is also possible to include ring flange, it is characterised in that this ultrasonic equipment uses launches bar as above.
Further, the connected mode launching bar and ring flange or horn of this ultrasonic equipment can be any connected mode, such as threaded, bolt connection, gluing connection, nested encryptions, frictional connection etc..As shown in Figures 1 to 6.Further, it is also possible to use two or more connected mode simultaneously, as frictional connection is connected use simultaneously etc. with gluing.
Present invention also offers the using method of ultrasonic equipment as above, it is characterised in that when using this ultrasonic equipment to process metal bath, its ultrasonic power is 100W to 25kW.In real work, the size of the distance (generally launching bar to the distance of solid-liquid solidification front) propagated, and ultrasonic effect to be needed according to ultrasound wave, select suitable ultrasonic power.Such as, use for laboratory monkey, crucible size is: diameter 100mm, high 100mm.This crucible melt cooled and solidified process is applied ultrasonic Treatment so that it is crystal grain refines, and its power can select 500W to 1000W even lower.For another example, industrial ultrasonic Treatment thermal insulation furnace melt (holding furnace capacity 100 tons), so that the hydrogen content of thermal insulation furnace melt reduces, the most high-power ultrasound wave of 10kW to 15kW can be selected to process, ultrasonic propagation just can be made to the melt of whole holding furnace and to reach degassing effect.
Preferably, before launching bar work, can preheat.This transmitting bar can be placed in above metal bath and preheat 0 ~ 8 hour, or in heating furnace, preheat 0 ~ 8 hour under 100 DEG C to 300 DEG C furnace temperature.On the one hand, transmitting bar can be made to be heated evenly, it is to avoid poly-cold heat build-up.On the other hand, it is possible to make steam or the globule evaporation of attachment on transmitting bar, it is to avoid bring in melt, explosion accident occurs.
Preferably, when using this ultrasonic equipment to process metal bath, its frequency is 5kHZ to 500kHZ, and the amplitude launching bar is 5um to 500um, the regulation frequency of ultrasonic emitting bar and amplitude, to reach optimal ultrasonic Treatment effect.
The invention has the beneficial effects as follows:
First, this transmitting bar can the corrosion of the most resistance to ultrasonic cavitation.This launches bar is to be formed by melten glass solidification, reach metallurgical binding degree to each other, when working under high temperature, even if each microcosmic particle does dither near equilbrium position, but owing to having reached metallurgical binding inside this transmitting bar, adhesion is very big, much larger than the power needed for dither, transmitting bar will not be made to produce layering, peeling.
Secondly, this transmitting bar can the corrosion of the most resistance to metal bath.This launches bar and is made up of glass, and glass is usually silicates nonmetallic materials (except SiO in quartz glass2Content be 99.9% outer), such as aluminium silicate, sodium silicate, calcium silicates etc..Additionally, also have some borate family glass, phosphoric acid salt glass etc..This kind of material general the most not with metal bath generation chemical reaction, therefore, this ultrasonic emitting bar can work for a long time in metal bath.Such as, during aluminium alloy casting, conventional lip, the objects such as son of picking up the ears, it is simply that use aluminosilicate fiberboard to make；Eighties of last century is used for filtering the glass cross filter (typically now using foamed ceramic filter plate) of aluminium alloy melt, also makes with aluminium silicate, and therefore, the transmitting bar made with alumina silicate glass also will not be with aluminum melt generation chemical reaction.Quartz glass also with high temperature iron melt without chemical reaction (but quartz glass with aluminum melt the most a small amount of chemical reaction can occur).Theory and practice all demonstrates, as long as having selected the glass of suitable species, this transmitting bar just can be made to work for a long time in metal bath, metal bath is shown corrosion resistance.
Furthermore, this transmitting bar can conduct ultrasound well.This launches bar and is made up of glass, and glass is by cooling down molding after high-temperature fusion, and interior solid, almost without hole, the scattering causing ultrasound wave is few, and conductive process causes ultrasonic intensity to weaken hardly.Meanwhile, according to data introduction, ultrasound wave spread speed in glass is 5660m/s, is more or less the same with its spread speed (5900m/s) in steel, only 4%.
Finally, the ultrasonic emitting bar of the present invention also has other advantages, as low in low cost, thermal conductivity etc..Piezoelectric ceramics in ultrasonic transducer is wanted normally to work, it is necessary under a certain temperature.Higher than this temperature, the efficiency of piezoelectric ceramics will reduce, and even result in piezoelectric effect and disappear.This launches the lower thermal conductivity (thermal conductivity of glass is the 1/400 of copper, is the 1/160 of aluminum) of bar, greatly reduces because conduction of heat causes the too high risk of piezoelectric ceramics temperature.
