Description

Technical Field

[0001] The utility model relates to the field of aluminum alloy casting, in particular to an automatic furnace eye flow control device. Background Art

[0002] Semi-continuous casting is one of the aluminum alloy processing technologies with the most widespread application, the most mature process and the most stable product quality. In the existing technology, the semi-continuous casting of aluminum alloys mostly adopts a fixed furnace eye flow control method to supply molten metal to maintain a stable casting liquid level. The stable molten metal supply is beneficial to avoid the tearing of the oxide scale and the involvement in slag formation. However, the current fixed furnace eye flow control mostly adopts high and low flow trough flow control plugs for manual flow control, which is difficult to operate, has a high risk factor and poor flow control effect.

[0003] With the development of technology, some automatic flow control devices have also appeared in the prior art. For example, a Chinese utility model patent with authorization announcement number CN213747843U discloses a furnace eye plugging device for an aluminum molten melting furnace, which drives the mounting seat to move through a hydraulic cylinder, thereby driving the push rod to move, and the push rod pushes the limit plate when moving, so that the limit plate drives the plugging rod to slide together, and pushes the plugging cylinder to move to the furnace eye to plug the furnace eye. In addition, the device is also provided with a clamping device to clamp and fix the plugging rod to prevent the plugging rod from moving due to shaking and affecting the plugging of the furnace eye. The clamping device includes a mounting plate, a fixing frame, a limiting threaded cylinder, a fixed threaded rod, an adjusting block, a first clamping seat, a second clamping seat and other structures, and its structure is relatively complex. The Chinese utility model patent with authorization announcement number CN215893260U discloses a furnace eye plugging device for an aluminum liquid mixing furnace. When working, the device uses a drive motor to drive a threaded sleeve to rotate, and then uses the threads in the threaded sleeve to drive the lead screw to move axially. The movement of the lead screw drives the plug to plug the furnace eye. However, the main innovation of the device is that during the casting of aluminum ingots, the lead screw is moved out of the outlet chute through the cooperation of the lifting drive and the rocker arm, thereby solving the problems of lead screw deformation caused by high temperature and short life of the drive motor. The lead screw that drives the plug to move in the device is still cantilevered, which is prone to shaking and affects the plugging of the furnace eye. Utility Model Content
