The molten aluminum heat-maintaining furnace part comprises a heat-maintaining furnace and a heat-maintaining furnace cover, and a furnace side opening is formed in one side of the heat-maintaining furnace; the molten aluminum conveying part comprises a flat pump groove connected with the furnace side opening, a conveying pipe connected with the flat pump groove, an electromagnetic pushing device arranged at the section, where the flat pump groove is formed, of the conveying pipe and an air cooling system; the electromagnetic pushing device comprises two electromagnetic pump bodies, traveling wave magnetic fields are generated by magnet yokes, iron cores and coils, the magnet yokes, the iron cores and the coils are arranged in the electromagnetic pump bodies, and the traveling wave magnetic fields are interacted with induced currents excited by the traveling wave magnetic fields in molten aluminum in the flat pump groove to generate electromagnetic pushing force to push the molten aluminum in the flat pump groove to flow; a magnetic gap between the two electromagnetic pump bodies can be adjusted. By means of the liquid-state aluminum alloy electromagnetic conveying device, the heat-maintaining furnace is sealed by the heat-maintaining furnace cover, and molten aluminum alloy is conveyed through the sealed conveying pipe; meanwhile, the molten aluminum alloy is processed by the electromagnetic fields in the conveying process, and the automation level, the production efficiency and the casting quality are improved.

Description

technical field [0001] The invention relates to a casting and conveying device for liquid aluminum alloy, in particular to an electromagnetic conveying device for liquid aluminum alloy which relates to the quantitative and accurate feeding of aluminum alloy liquid in pressure casting and gravity casting production. Background technique [0002] At present, in the production of aluminum alloy die-casting at home and abroad, manipulators are mainly used to feed soup. Since the aluminum alloy liquid is transported from the holding furnace to the feeding cylinder of the die-casting machine with a manipulator ladle, an open manipulator ladle must be provided in the holding furnace to directly dissipate heat to the outside, resulting in high energy consumption of the holding furnace and the opening of the holding furnace.

AI Technical Summary

Problems solved by technology

Since the aluminum alloy liquid is transported from the holding furnace to the feeding cylinder of the die-casting machine with a manipulator ladle, an open manipulator ladle must be provided in the holding furnace to directly dissipate heat to the outside, resulting in high energy consumption of the holding furnace and the opening of the holding furnace. Oxidation of the liquid surface and other problems, which requires manual slag removal from time to time, affects the automation level of casting production and causes waste of aluminum alloy liquid materials

During the process of conveying the aluminum alloy liquid through the manipulator scoop, the aluminum alloy liquid directly contacts with the air, which causes the oxidation of the aluminum alloy liquid and affects the quality of the aluminum alloy casting. fall, resulting in waste of aluminum alloy liquid and deterioration of the casting production environment

In addition, the soup feeding cycle of the manipulator is generally 15-38s, which is relatively long and affects the casting production efficiency

In addition, for die-casting parts that cannot be core-pulled, gravity casting must be used. At present, manual casting is generally used in gravity casting, which is labor-intensive and has low automation and production efficiency.
