Embodiment 1

[0034] According to the characteristics of casting machine production, through many on-site analysis, research and multiple tests, it is decided to start from the two aspects of the non-demolding detection alarm device and the second strike system, through the electrical control circuit and PLC automatic control, so that the non-demolding Aluminum ingot demoulding.

[0035] Mechanical part

[0036] The mechanical part is composed of a non-demolding detection device and a secondary strike system. The main function of the non-demolding detection device is that when the aluminum ingot is not demoulded after being struck by the primary strike system, the detection device automatically detects the non-demolding aluminum ingot , and send a signal to the control system; the function of the secondary strike system is that after receiving the signal from the detection device, the PLC electrically executes the original control, and the secondary strike system acts to demould the aluminu...

Abstract

The invention relates to the technical field of aluminum smelting, in particular to a stripping failure detection, alarming and secondary knocking unit for a 20kg aluminum ingot continuous caster. The stripping failure detection, alarming and secondary knocking unit comprises a secondary knocking device, a stripping failure detector and an electrical control device. The stripping failure detection, alarming and secondary knocking unit has the advantages that the unit is capable of accurately knocking an aluminum ingot failed to be stripped, the unit is ingeniously designed, compactly structured and highly automated in the limited space of the 20kg aluminum ingot continuous caster, the unit allows accurate stripping by knocking, the major safety hazard that stripping failure of the aluminum ingot causes explosion of molten aluminum is eliminated, and the unit is applicable to a production line of 20kg aluminum ingot continuous casters in the industry of aluminum electrolysis.

Description

technical field [0001] The invention relates to the technical field of aluminum smelting, in particular to a 20kg aluminum ingot continuous casting machine non-demolding detection alarm and secondary strike device. Background technique [0002] During the production of 20kg aluminum ingots, due to cracks on the surface of the casting mold or excessive temperature of the casting mold, the aluminum ingots in the casting mold will not be demoulded smoothly at the receiving position after the first demoulding blow, and the production personnel will not find out in time, then When the casting mold that has not been demolded is running to the pouring position, a large amount of primary aluminum will overflow the casting mold and enter the cooling water tank at the lower part of the casting machine. Whenever the above situation occurs, the production line must be shut down urgently with the furnace hole blocked, and the casting mold must be disassembled and placed in the water tank....
