Abstract
The present invention discloses a method for mixing pseudo alloy solution of aluminum oxide with 5 percent of iron, which belongs to the field of research on mixing of the pseudo alloy solution of aluminum oxide with 5 percent of iron. The method combines a straight-blade crucible and electromagnetic mixing, and is applied in mixing of the pseudo alloy solution of aluminum oxide with 5 percent of iron when straight blades are inclined with an angle beta of 32-34 degrees upwards and forwards in the length direction and with an angle gamma of 78-80 degrees upwards in the width direction. When the method is applied, the uniform distribution of aluminum oxide particles can be realized quickly, and the mixing time can be reduced to 7 minutes.
Description
Technical field
The present invention relates to the stirring means of a kind of iron-5 aluminium oxide fake alloy liquid.
Background technology
Publication number: CN1919433, denomination of invention: on " a kind of lightweight solid particle fake alloy liquid stirring means and device of containing ", set forth the stirring means of aluminum-7 plumbago fake alloy liquid, that is, adopting conventional rotating electromagnetic stirring to be furnished with the prismatic blade graphite crucible mode that combines with inwall stirs the aluminum-7 plumbago fake alloy liquid that contains the 7wt% graphite granule.In this prismatic blade crucible+electromagnetic agitation method, rotating electromagnetic stirs the circumferential laminar motion that makes the fake alloy liquid generation rule, prismatic blade on the crucible inwall has then changed the circumferential laminar motion state of rule of fake alloy liquid, forward angle of inclination beta has applied outside active force to fake alloy liquid on the length of blade direction, and fake alloy liquid has been produced from crucible inside to the additional laminar motion of outside; And the inclination angle γ that makes progress on width has applied downward active force to fake alloy liquid, fake alloy liquid has been produced from crucible top to the additional laminar motion of bottom, like this, by stir can be constantly the fake alloy liquid of inside be moved on to around, the fake alloy liquid on top moved on to the bottom, and then stoped the come-up of particle in the fake alloy liquid and central authorities are poly-partially moves.Disclosed β is that 20～30 °, γ are under 35～50 ° of conditions in patent CN1919433, and the particle in the fake alloy liquid is exactly to rely on 10～15 minutes additional laminar motion to realize even distribution.
Iron-5 aluminium oxide fake alloy liquid is the fake alloy liquid that contains 5wt% alumina particle and 95wt% iron liquid, stirring for iron-5 aluminium oxide fake alloy liquid, because especially the difference between the density is bigger than the difference of aluminium and graphite granule for the rerum natura of iron and alumina particle, graphite density is 1.9～2.2g/cm
3, aluminium liquid density is 2.6～2.8g/cm
3, iron liquid density is 7.0～7.9g/cm
3, alumina density is 3.9～4.1g/cm
3, therefore realize that the even distribution of alumina particle in iron-5 aluminium oxide fake alloy liquid is more difficult, that is to say, be used for realizing that alumina particle can be longer in the equally distributed mixing time of iron-5 aluminium oxide fake alloy liquid.
For iron-5 aluminium oxide fake alloy liquid, realizing under the equally distributed prerequisite of alumina particle, the time that is used to stir is short more, energy consumption is more little, cost is low more, and the pollution that iron-5 aluminium oxide fake alloy liquid is subjected to is also few more, and its quality is high more, therefore can realize that the mixing time of alumina particle equally distributed iron-5 aluminium oxide fake alloy liquid is short more good more.
Summary of the invention
Technical problem to be solved by this invention is, overcome the deficiency of existing stirring means " mixing time is long ", a kind of stirring means that can realize alumina particle equally distributed iron-5 aluminium oxide fake alloy liquid fast is provided, further shortens and realize the equally distributed mixing time of alumina particle.
The technical solution adopted for the present invention to solve the technical problems is: adopt prismatic blade crucible+electromagnetic agitation method, the γ that is inclined upwardly on the β that turns forward on the prismatic blade length direction is 32～34 °, width under 78～80 ° the condition, stirs iron-5 aluminium oxide fake alloy liquid.
The invention has the beneficial effects as follows: for the particle in the fake alloy liquid, want to finish as early as possible its dispersion in fake alloy liquid, must strengthen stirring intensity.In prismatic blade crucible+electromagnetic agitation method, increase along with blade γ, the intensity of variation of the laminar motion state of fake alloy liquid after flowing through blade increases gradually, when γ increases to certain value, except producing additional laminar motion, also will produce the additional turbulent motion of fake alloy liquid, should have profound part stirring and peptizaiton to the particle in the fake alloy liquid by additional turbulent motion, the present invention utilizes the additional turbulent motion that produces after β and the γ optimum organization further to promote the even distribution of alumina particle in fake alloy liquid, thereby has reached the purpose that shortens mixing time.Utilize the present invention, iron-5 aluminium oxide fake alloy liquid is stirred, realize that the equally distributed mixing time of alumina particle can shorten to 7 minutes, shortened 30% at least than the shortest mixing time of CN1919433 patent.
