Embodiment
Be described in detail below in conjunction with 1,2,3 pairs of the utility model of accompanying drawing.
Molten metal rotation of the present utility model is stirred refining plant by silicon controlled rectifier temperature housing (1), three-dimensional extension lifting swivel mount (2), mounting plate (3), AC induction motor (4), rotation ventilation tightness system (5), electric capacity (6), speed regualtion of AC motor device (7), knotmeter (8), gear (9), bearing support (10), hollow transmission rod (11), graphite stirring rod (12), asbestos insulation cover (13), plumbago crucible (14), molten metal (15), resistance furnace (16), thermopair (17), data acquisition module (18) and computer (19) are formed; Graphite agitator arm (12) links to each other with hollow transmission rod (11), and hollow transmission rod (11) connects with knotmeter (8) through gear (9), and knotmeter (8) is directly driven by AC induction motor (4); The external stability of rotation ventilation tightness system (5) is on mounting plate (3), and the top links to each other with ventpipe, and inner hollow, and rotatable and link to each other with hollow transmission rod (11) innerly relatively rotates with the outside, and seals and prevent to leak gas; Bearing support (10) is fixed on the mounting plate (3), and hollow transmission rod (11) passes wherein; Speed regualtion of AC motor device (7) is connected with AC induction motor (4), is input to the frequency of AC induction motor (4) power supply by change, and the output speed of regulating AC induction motor (4) is adjusted the speed of rotation of hollow transmission rod (11); Data acquisition module (18) is made up of frequency acquisition module, temperature collect module and modular converter, frequency acquisition module, temperature collect module link to each other with modular converter respectively, modular converter is connected with computer (19) COM serial port, frequency acquisition module links to each other with knotmeter by data line, temperature collect module links to each other with the thermopair that is inserted in the plumbago crucible wall, when the hollow transmission rod drives graphite stirring rod stirring molten metal, can gather tach signal and temperature signal simultaneously.
In the experimentation, sample heats and is controlled by silicon controlled rectifier temperature control cabinet the heating and the holding temperature of sample in resistance furnace.Speed regualtion of AC motor device 7 is connected with AC induction motor 4, is input to the supply frequency of AC induction motor 4 by change, and the output speed of regulating AC induction motor 4 is adjusted the speed of rotation of hollow transmission rod 11, and this speed is measured by knotmeter.Rare gas element enters hollow transmission rod 11 and graphite stirring rod 12 from rotation ventilation tightness system 5, enter melt from the production well between the stirring-head flabellum again, the stone mill rod can be smashed and be evenly distributed on bubble in the crucible when stirring, bubble can adsorb being mingled with in the melt, hydrogen in the melt is because the dividing potential drop relation enters in the bubble, and bubble floating just can be brought into being mingled with hydrogen in the melt in the atmosphere.Data collecting system is made up of a modular converter and two acquisition module data, and wherein frequency module is gathered tach signal, thermal module collecting temperature signal, and modular converter is connected with computer C 0 M serial port.The data message that module is obtained is to change as module and computer program communication signals by the ActiveX control interface that provides on the product CD.The temperature of data collection system synchronizing record rotating speed and sample.Whole procedure comprises two portions, and a part is data gathering and real-time online procedure for displaying, and a part is that data compare and analysis for data reproduction in addition.With object-oriented programming language Visual Basic programming the data of gathering are handled, calculated, speed of rotation and the variation of temperature of record molten metal in process of the test.Because input of the energy of native system and signal output are to be born by the special ring-shaped transformer of two groups of band gaps, have therefore realized the contactless energy and signal transfer function.Reduce the signal interference like this, improved the data gathering precision of device.
Fig. 2 be 730 ℃ of following different rotating speeds of uniform temp to aluminium alloy A356 in the graph of a relation of hydrogen richness.As can be seen from the figure: speed of rotation is high more, and molten intravital hydrogen richness is low more.This is because rotating speed makes stirring-head produce bigger shearing force, and bubble is smashed, and bubble is tiny more, and floating interval of floating dock is just long, just can absorb hydrogen and absorption impurity fully.This is also consistent with theoretical analysis.The hydrogen richness that does not rotate when this figure it can also be seen that 0r/min when stirring is bigger than the hydrogen richness after stirring, and it can be said that bright rotation to stir purification to alloy very big influence and stirring velocity are arranged is the important factor that influences hydrogen richness in the melt.
Fig. 3 be under same rotational speed 80r/min differing temps to the graph of a relation of hydrogen richness among the aluminium alloy A356.As can be seen from the figure: along with the rising of teeming temperature, the hydrogen richness of A356 is also along with rising.This is that all corresponding rising of spread coefficient and solubleness helps inhaling hydrogen owing to the rising along with the molten aluminium teeming temperature.The rising of temperature helps this balance and moves to inhaling the hydrogen process.This is consistent with temperature and aluminium alloy hydrogen richness theory relation, illustrates that temperature controlling also has very big influence to the purification of alloy.
