Description
Technical Field
The utility model belongs to the technical field of the founding, in particular to accuse flow of founding usefulness is cursory.
Background
The production process of the alloy wire refiner of Al-Ti-B, al-Ti-C, al-Sr and the like mainly comprises continuous casting and continuous rolling and continuous casting and continuous extrusion, however, the molten liquid in the holding furnace is transferred into a continuous casting machine and needs to be realized through the cooperation of a launder and a plurality of ladles, but if the flow rate of the liquid cannot be timely controlled in the flowing process, the fluctuation of the liquid level is easily caused, so that the molten liquid is continuously contacted with air to form oxidation impurities, and the quality of products is influenced.
In order to solve the problems, the Chinese utility model with the publication number of CN205496535U discloses an aluminum alloy casting device, and the scheme provides that a liquid level control device comprises a frame, a lever, a stopper rod and a buoy; the lever is pivotally arranged on the rack, a stopper rod and a buoy are respectively arranged at two ends of the lever, one end of the stopper rod is movably connected with the lever so that the stopper rod vertically hangs above a lower injection pipe of the flow plate all the time, the buoy and the stopper rod are positioned at the same side of the lever, and the buoy is connected with the lever through a buoy connecting rod; the buoy rises and falls along with the liquid level, and the stopper rod at the other end of the lever moves in the opposite direction; the liquid level rises, and the stopper rod descends and pours into the pipe between the space dwindles, and the liquid level descends, and the stopper rod rises and pours into the pipe between the space increase to supply the increase and decrease of flow through the lift automatic control of the interior liquid level of crystallizer, make the interior liquid level of crystallizer realize dynamic balance, keep in reasonable within range, can not cause the liquid level to roll simultaneously, avoid introducing secondary pollution.
However, in the practical process, the scheme has the following defects:
1) Because the float has a certain weight, when the liquid level rises, the melt liquid can not timely lift the float to drive the stopper rod to move downwards to control the flow rate of the melt liquid, so that the fluctuation of the liquid level is caused, the oxide film on the surface layer of the liquid level is broken, and the melt liquid below the liquid level contacts with air to generate new impurities.
2) The equipment with a pure mechanical structure is easy to generate certain abrasion at the joints among all parts to generate gaps along with the time, so that at the moment of liquid level change, the flow control device with a lever structure has short gap compensation time, namely, the float moves, the stopper rod is still in a static state, and the situation still causes the fluctuation of the liquid level to generate new impurities in the molten liquid.
Therefore, the current flow control device usually adopts a floating flow control device directly connected with the flow guide pipe (the floating structure is shown in figure 1), the floating structure adopts a through hole with three flow guides opened on the side surface, and the top plate is provided with a through hole for the floating structure to move up and down along the outer wall of the flow guide pipe, but the floating structure still has defects in the practical process, namely, the bottom plate of the floating structure is easy to block the liquid outlet of the flow guide pipe, so that the flow of the through hole on the side surface is reduced, therefore, molten liquid can flow out from the gap between the floating structure and the flow guide pipe, so that the molten liquid is contacted with air to form oxidation impurities, and then enters products, thereby affecting the product quality, meanwhile, the bottom plate of the floating structure blocks the liquid outlet of the flow guide pipe, and also indirectly leads to the fluctuation of the liquid level, thereby destroying the oxidation film on the surface layer of the liquid level, and leading the molten liquid below the liquid level to be contacted with air to generate new impurities. Therefore, it is necessary to design a float which can control the flow rate and prevent the liquid level from fluctuating.
