Abstract
The invention discloses a method for stirring zinc-3graphite pseudo-alloy liquid and belongs to the field of research on zinc-3graphite pseudo-alloy liquid stirring. Under the conditions that beta inclined upwards in the length direction of a straight blade is 34 to 36 degrees and gamma inclined upwards in the width direction of the straight blade is 66 to 68 degrees, the zinc-3graphite pseudo-alloy liquid is stirred by a straight blade crucible+electromagnetic stirring method, so that graphite particles can be distributed uniformly and quickly, and the stirring time can be shortened to be 7 minutes.
Description
Technical field
The present invention relates to the stirring means of a kind of zinc-3 graphite 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.
Zinc-3 graphite fake alloy liquid is the fake alloy liquid that contains 3wt% graphite granule and 97wt% zinc liquid, stirring for zinc-3 graphite 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 zinc and graphite granule, graphite density is 1.9～2.2g/cm
3, aluminium liquid density is 2.6～2.8g/cm
3, zinc liquid density is 6.3～7.2g/cm
3, therefore realize that the even distribution of graphite granule in zinc-3 graphite fake alloy liquid is more difficult, that is to say, be used for realizing that graphite granule can be longer in the equally distributed mixing time of zinc-3 graphite fake alloy liquid.
For zinc-3 graphite fake alloy liquid, realizing under the equally distributed prerequisite of graphite granule, the time that is used to stir is short more, energy consumption is more little, cost is low more, and the pollution that zinc-3 graphite fake alloy liquid is subjected to is also few more, and its quality is high more, therefore can realize that the mixing time of graphite granule equally distributed zinc-3 graphite 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 graphite granule equally distributed zinc-3 graphite fake alloy liquid fast is provided, further shortens and realize the equally distributed mixing time of graphite granule.
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 34～36 °, width under 66～68 ° the condition, stirs zinc-3 graphite 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 graphite granule in fake alloy liquid, thereby has reached the purpose that shortens mixing time.Utilize the present invention, zinc-3 graphite fake alloy liquid is stirred, realize that the equally distributed mixing time of graphite granule can shorten to 7 minutes, shortened 30% at least again than the shortest mixing time of CN1919433 patent.
