Description
Technical field
The utility model relates to a kind of melting of metal refining plant, and refining plant is stirred in the compound air blowing of particularly a kind of metal melt rotatingfield.
Background technology
In the prior art, the metal melt refining plant has mechanical stirring device and single air blowing whipping appts, the ubiquity purification efficiency is not high, be difficult to remove particle diameter tiny as the inclusion below 30 microns, perhaps the clarification time is oversize, the purification efficiency instability, the metal melt treatment capacity is little, the inclusion problems such as discharging of can not opening a way.
The utility model content
The purpose of this utility model is to provide the compound air blowing of a kind of metal melt rotatingfield to stir refining plant, can remove 10 microns even thinner microinclusions, and the discharging inclusion of can opening a way is realized continuous purification, improves purification efficiency and purifying treatment amount.
For achieving the above object, the utility model adopts following technical proposals:
Refining plant is stirred in the compound air blowing of a kind of metal melt rotatingfield, comprises that top and the bottom have the metal melt container of import and export respectively, it is characterized in that metal melt container periphery is provided with a rotating magnetic field generator, and the bottom is provided with blowing device.
Above-mentioned metal melt container is the stainless steel cylinder of a upward opening, and inwall is with refractory masses.
The structure of above-mentioned blowing device is: the porous ceramics piece is installed in the bottom at the metal melt container, and the porous ceramics piece is connected extraneous source of the gas by gas duct.
The utility model compared with prior art, have following conspicuous characteristics and advantage: rotating magnetic field generator and blowing device are set in the utility model, metal melt produces rotation under the effect of rotatingfield, blowing device is blown into the small bubbles of disperse from container bottom, melt is under the rotary centrifugal force effect and under small bubbles rising and the adsorption, make inclusion floating in the melt to the metallic surface, by taking off slag operation, realize open circuit discharging inclusion, advance metal melt and go out metal melt by the import and export of container, realize the continuous purification processing.The utility model can be removed 10 microns even thinner microinclusions, and purification efficiency is higher, and the purifying treatment amount is big, is applicable to the purifying treatment of various metals and alloy melt.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the sectional view at A-A place among Fig. 1.
Embodiment
A preferred embodiment of the present utility model is: referring to Fig. 1 and Fig. 2, the compound air blowing of this metal melt rotatingfield is stirred refining plant and is included the metal melt container 12 that top and the bottom have import and export 1,10 respectively, metal melt container 12 peripheries are provided with a rotating magnetic field generator 3, and the bottom is provided with blowing device 11.Above-mentioned metal melt container 12 is the stainless steel cylinder 4 of a upward opening, and inwall is with refractory masses 5.The structure of above-mentioned blowing device 11 is: porous ceramics piece 8 is installed in the bottom at metal melt container 12, and porous ceramics piece 8 is connected extraneous source of the gas by gas duct 10.The gas that is blown into is argon gas, nitrogen, chlorine etc., also can sneak into the liquid phase substance that generates gas phase with fusant reaction, as tetracol phenixin etc.
Working process of the present utility model is as follows: metal melt 2 is entered into by Stainless Steel Case 4 by inlet 1, in the container that refractory masses 5 and rotating magnetic field generator 3 are formed, gas is blown into the metal pool bottom by stainless steel gas body canal 10 and porous piece 8, form the small bubbles 7 of disperse, to adsorb non-metallic inclusion 6 in the floating-upward process, under the rotatingfield effect that rotating magnetic field generator 3 produces, metal melt 2 produces rotation, inclusion 6 and bubble will be to metal pool center and top migrations, assemble to grow up entering metal pool top slag blanket or flux layer 11 at last, flow out by metal melt outlet 9 through the metal melt 2 after purifying.
Principle of work of the present utility model is as follows: be blown into gas in metal melt 2, as argon gas, chlorine etc., form the small bubbles 7 of many continuous risings, the effect of small bubbles 7 not only can be removed the gas in the metal melt, can also catch the non-metallic inclusion 6 in the metal melt, float to metal melt 2 tops with inclusion 6 then, in addition, through porous piece 8 is blown into gas in metal melt 2 when, open rotating magnetic field generator 3, produce the rotatingfield of certain rotating speed, because metal melt 2 is the good conductor of electricity, therefore when cutting magnetic line, to produce induced current in the metal melt 2, this induced current and rotatingfield interact, to impel metal melt 2 along with the rotatingfield rotation, because there is difference in inclusion 6 with metal melt 2 density in the metal melt 2, density will be moved to the center than metal melt 2 little inclusiones 6, density will be moved to periphery than metal melt 2 big inclusiones 6, but behind small bubbles 7 dross inclusion adsorptions 6, both compound mean densities will be less than molten metal density, the result causes inclusion 6 and bubble 7 aggregates to move to the center, and in the accumulative process of center, inclusion 6 concentration in center are more and more higher, making inclusion 6 probability of collision and bubble 7 merge probability increases greatly, cause inclusion 6 and bubble 7 polymer diameters to be grown up rapidly, because inclusion 6 and the ascent rate of bubble 7 polymers in metal melt 2 and its diameter square are directly proportional, therefore microinclusions 6 can be grown up fast and float rapidly to metal melt 2 surfaces, thereby reaches the purpose of refining molten metal 2.Metal melt 2 surface coverage can be absorbed the flux of inclusion 6, the inclusion 6 of come-up can be absorbed in the flux, by taking off slag operation, can be with inclusion 6 open circuit dischargings.
