Abstract
The invention discloses a molten aluminum flow control system which comprises a trough, a gate valve, a driving device and a mounting support. The trough is used for delivering molten aluminum; the gate valve comprises a gate valve body and a valve element, and the gate valve body is arranged in the trough in a close fit manner; the driving device comprises an actuator and a fixing platform, the fixing platform is used for fixing the actuator, and the actuator is connected with the valve element and is coaxially arranged above the valve element; the mounting support is used for mounting the fixing platform. The molten aluminum flow control system has the advantages that the flow of the molten aluminum in the trough can be automatically steplessly regulated, the actuator and the valve element are arranged on the same axis, accordingly, transmission chains are short, gaps are small, the control precision can be improved, and the manual control labor intensity can be relieved.
Description
Technical field
The present invention relates to aluminium and aluminum alloy smelting field, be specifically related to a kind of aluminium flow quantity control system.
Background technology
In aluminium and aluminum alloy smelting field, often the aluminium liquid of having smelted is delivered to the next process such as aluminium pig casting machine or casting and rolling machine by chute from smelting furnace, because manufacturing technique requirent as met liquid aluminum fluctuation in ± 0.3mm in next process, need convection current to carry out trace to the aluminium flow quantity in chute in next process and control even liquid aluminum height lower than setting value, control a little large flow, vice versa.Patent documentation CN201399468Y disclose in chute arrange have the import of aluminium liquid every Flow Control plate, graphite chock plug is arranged in the import of aluminium liquid, regulates the stopper rod on graphite chock plug to control the flow of aluminium liquid and then the height of control liquid aluminum with the adjusting hole of connecting rod.The shortcoming one of this technical scheme is to guarantee that under the prerequisite of normal required aluminium flow quantity, the opening degree of graphite chock plug and the import of aluminium liquid is larger, rises only micro-ly or falls graphite chock plug and all can cause several millimeters of even larger liquid aluminum fluctuations in next process; The 2nd, between stopper rod and adjusting hole, be have level to regulate and need artificial participation, labour intensity is large, control accuracy is low and automaticity is low.
Summary of the invention
The object of the present invention is to provide a kind of aluminium flow quantity control system, can solve aluminium liquid in above-mentioned existing chute and be difficult to realize under the prerequisite of certain flow trace and control with liquid aluminum fluctuation in meeting next process in ± 0.3mm and the technical problem that Artificial Control aluminium flow quantity labour intensity is large, control accuracy is low and automaticity is low.
For achieving the above object, the invention provides a kind of aluminium flow quantity control system, comprising: chute, for delivery of aluminium liquid; Slide valve, comprises flashboard valve body and spool, and this flashboard valve body is snugly arranged in chute; Drive unit, comprises actuator and for fixing the fixed platform of this actuator, actuator connects spool and is coaxially arranged on the top of this spool; Mounting bracket, for installing fixed platform.
Further, the top of the bottom of flashboard valve body and flashboard valve body is respectively equipped with the first aluminium liquid passage and the second aluminium liquid passage, and one end of spool is arranged in the second aluminium liquid passage, and the top that the other end of spool stretches out flashboard valve body is connected with actuator.
The sectional area of the channel section of the second aluminium liquid passage coordinating with spool further, flows out direction along aluminium liquid and reduces gradually and come together in the first aluminium liquid passage.
Further, actuator is electric cylinder.
Further, actuator is hydraulic cylinder.
Beneficial effect of the present invention: the 1. spool of slide valve is connected with actuator, has realized the aluminium flow quantity automatic stepless in chute and has regulated, and has improved control accuracy, has reduced manually operated labour intensity; 2. actuator and spool are arranged on same axis, and driving-chain between them is short, gap is little, has further improved control accuracy; 3. slide valve is provided with two aluminium liquid passages, and the first aluminium liquid passage guarantees normal needed main flow, and the second aluminium liquid passage carrys out the flow of the whole aluminium liquid of micro-control by spool, can meet in next process liquid aluminum and fluctuate in ± 0.3mm.
Except object described above, feature and advantage, the present invention also has other object, feature and advantage.Below with reference to figure, the present invention is further detailed explanation.
Accompanying drawing explanation
Fig. 1 is the aluminium flow quantity control system schematic diagram of the preferred embodiment of the present invention;
Fig. 2 is the slide valve structural representation of the preferred embodiment of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
As shown in Figure 1-2, aluminium liquid 2 flows to from left to right next process in chute, and slide valve 3 is arranged in chute 1.Slide valve 3 comprises flashboard valve body 3a and spool 3b, and the bottom of flashboard valve body 3a is provided with the first aluminium liquid passage, and in the size of this passage and next process, needed aluminium flow quantity Q adapts.The aluminium liquid that the bottom that the first aluminium liquid passage 3c1 is arranged on flashboard valve body 3a is beneficial in casting chute in latter stage 1 enters next process entirely, prevents the waste of aluminium liquid.Closely cooperate for realizing flashboard valve body 3a and chute, the cross sectional shape of flashboard valve body 3a is suitable with the cross sectional shape of chute 1 and scribble fire clay on the flashboard valve body 3a surface relative with chute 1.The second aluminium liquid passage 3c2 is arranged on the top of flashboard valve body 3a, and this passage is divided into and is parallel to respectively and perpendicular to entrance and the outlet section of the first aluminium liquid passage 3c1, and the sectional area of outlet section flows out direction along aluminium liquid and reduces gradually and come together in the first aluminium liquid passage 3c1.For realizing the trace control to whole aluminium flow quantity, the channel sized of the second aluminium liquid passage 3c2 is much smaller than the size of the first aluminium liquid passage 3c1.It is upper that spool 3b is arranged on the second aluminium liquid passage 3c2, and the outlet section of the core print of spool 3b and the second aluminium liquid passage 3c2 is suitable, and the core tail of spool 3b is connected through the top of flashboard valve body and the chief component component actuation device 4b of drive unit.Actuator 4b drives spool 3b to carry out lifting and repeatedly moves and realize the trace control of aluminium flow quantity Q ', actuator 4b can realize step-less adjustment, be Q ± Q ' by the overall flow of slide valve like this, can not cause the fluctuation of exceed ± 0.3mm of liquid aluminum in next process.In the present embodiment, actuator is electric cylinder; In other embodiments, actuator also can be hydraulic cylinder.Drive unit also comprises fixed platform 4a, is arranged on the actuator 4b of spool 3b top for fixing coaxial.Fixed platform 4a is arranged on mounting bracket 5, and alternatively, mounting bracket can be fixed on chute 1 or on ground.For ease of operation, fixed platform 4a can be along the axial-rotation of mounting bracket 5.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
