Abstract
Smelting furnace stirring apparatus with writhing effect and without any metal component aliquation in the production of alloy contains bottom established permanent magnet stirrer (3) with a driving mechanism on it driving the stirrer to reciprocate up and down. The invention can be used as the stirring device for smelting metal in the production of alloy.
Description
Technical field
The present invention relates to the whipping appts of Metal Melting furnace.
Background technology
Aluminium alloy is used by many fields with its distinctive performance.Industries such as particularly space flight, military project and automobile making, should using of aluminium alloy is extensive more, simultaneously to the various demands for higher performance of aluminium alloy.This means the manufacturing equipment of aluminium alloy is had higher requirement, wherein is that the manufacturing of aluminum alloy materials of high alloy composition, high-mechanical property of representative is more outstanding with the wrought aluminium alloy.
In the manufacturing process of traditional contour alloying constituent of wrought aluminium alloy, the alloying constituent that must add mostly is high specific gravity, dystectic heavy metal, therefore, not only production efficiency is low, unit consumption of energy is big, and the easy segregation of alloying constituent, is difficult to obtain high-quality product.
In the Metal Melting of making aluminium alloy, the induction stirring that released one after another in recent years and main frequency furnace smelting technique.Though the employing of these two kinds of technology provides new selection for the raising of aluminium alloy quality, but in actual application, electromagnetic stirring equipment is because of safeguarding the high raising that has influenced productivity of complexity, failure rate, and factor such as big and cost of investment height causes production cost high because of energy consumption; The main frequency furnace melting is too little because of itself capacity, and the unit cost of use is too high, is difficult to realize scale and benefit aborning.So restricted in actual the popularization in above-mentioned two kinds of technology, do not possessed the requirement of standard configurations.
The new recently permanent magnetism stirring technique of releasing, though obtaining creationary breakthrough aspect cutting down the consumption of energy and boosting productivity, but the bottom type stirrer in this product line, its alr mode is too single, have only the rotation of horizontal direction to stir, contain in the alloy manufacturing of a high proportion of infusibility heavy metal at some, the segregation that can produce the vertical direction of heavy metal influences product quality.
Summary of the invention
The present invention will solve alloy material and adopt the permanent magnetism stirrer to cause the problem of heavy metal segregation because of alr mode is single in the melting manufacturing, provide a kind of band of the present invention to seethe the smelting furnace whipping appts of effect for this reason, this device has the compound alr mode of multidimensional, its heavy metal distributed components of alloy that melting is made does not produce segregation.
For addressing the above problem, the technical solution used in the present invention is to be provided with bottom type permanent magnetism stirrer, and its special character is to be provided with to make the upper and lower reciprocating driving mechanism of described bottom type permanent magnetism stirrer on bottom type permanent magnetism stirrer.
The described upper and lower reciprocating driving mechanism of bottom type permanent magnetism stirrer that makes can be meant: be provided with hydraulic ram below the framework of bottom type permanent magnetism stirrer, be associated with reversing valve on the hydraulic ram and by motor-driven hydro-pump.
The described upper and lower reciprocating driving mechanism of bottom type permanent magnetism stirrer that makes also can be meant: be provided with cylinder below the framework of bottom type permanent magnetism stirrer, be associated with reversing valve and air pump on the cylinder.
The described upper and lower reciprocating driving mechanism of bottom type permanent magnetism stirrer that makes can be meant again: be provided with eccentric wheel/connecting rod/cam mechanism below the framework of bottom type permanent magnetism stirrer, be associated with the motor (chain-drive mechanism of driving on eccentric wheel/connecting rod/cam mechanism.
The described upper and lower reciprocating driving mechanism of bottom type permanent magnetism stirrer that makes can also be meant: be associated with tooth bar on the framework of bottom type permanent magnetism stirrer, be combined with gear on the tooth bar, be associated with motor-driven chain-drive mechanism on the gear.This motor is realized the upper and lower commutation campaign of tooth bar for the commutation rotary electric machine.
The effect of institute's connection reversing valve is the direction of motion of control hydraulic efficiency oil, high pressure gas on hydraulic ram of the present invention, the cylinder, thus the direction of motion of control piston bar.When the magnet coil no power of pilot valve, moving iron core resets under spring action, and the P hole of reversing valve and 01 hole connect, and B hole and 02 hole connect, and the pressure medium of hydraulic ram, cylinder inner cavity promotes piston to outer displacement; When coil electricity, moving iron core is by adhesive, and the P hole of reversing valve and 02 hole connect, and B hole and 01 hole connect, and described medium input hydraulic pressure oil cylinder, cylinder exocoel promote piston and inwardly move, and realize commutation.
When bottom type permanent magnetism stirrer under upper and lower reciprocating driving mechanism effect, bottom type permanent magnetism stirrer is done upper and lower to-and-fro movement, making the action of a magnetic field is that the magnetic flux of the molten metal of melting produces circulation change in melt.Change according to magnetic flux by unit cross-sectional area, conductor is will produce eddy current in the molten metal sectional area, the magnetic field that eddy current produces will stop the magnetic flux change by sectional area, so the magnetic field that eddy current produces will produce the power opposite with described vibration-direction to the magnet steel group of permanent magnetism stirrer rotation, in like manner, magnetic field will produce and described vibration-direction opposite effect power F the molten metal that produces eddy current, molten metal is under the effect of reactive force F, produce the motion identical with the magnetic field vibration-direction, following magnetic field, magnetic field does, following to-and-fro movement realizes the effect of seething of melt inside.
When horizontally rotate when motion of above-mentioned motion superposition in bottom type permanent magnetism stirrer, the molten metal in the smelting furnace will be made plane rotation and the upper and lower compound motion that springs up.This moving handle takes the molten metal surface than heavy metal composition great, that easily be deposited in molten metal bottom in the mode of vertical movement, equably the heavy metal composition is diffused in the whole melt by tangential movement then.In conjunction with production realization situation, can regulate the amplitude and the frequency of vertical movement, control the intensity of seething of alloy liquid.By with the reasonable combination of horizontal direction stirring velocity, finally realize best mixing effect.
The present invention is under described upper and lower reciprocating driving mechanism effect, and bottom type permanent magnetism stirrer is done upper and lower to-and-fro movement, and the amplitude of upper and lower motion is generally 100 millimeter, and the time of upper and lower motion one-period generally was advisable with 2～2.5 seconds.
The present invention is owing to be provided with on bottom type permanent magnetism stirrer and make the upper and lower reciprocating driving mechanism of described bottom type permanent magnetism stirrer, thus the alloy material of melting manufacturing, aluminum alloy materials for example, its heavy metal distributed components can not produce segregation.
