Abstract

The invention discloses a multifunction crown block aluminum producing auto control method and the device. When using multifunction crown block delivery package and siphoning aluminum from aluminum electro-bath by siphoning system, controlling the siphoning flow rate according to weighting the aluminum ladle in a certain period, comparing the siphoning flow rate to the set rating aluminum quantity in the program controller to determine the time to stoop the siphoning system, then, the siphoning system would be stopped according to the calculated time. The advantage of invention is that: it could automatically control the aluminum producing process; and it could realize controlling of single groove indicatrix and the real aluminum producing.

Description

Technical field: [0001] The invention relates to an automatic control method and device for aluminum output by a multifunctional crane used in aluminum electrolysis production, and belongs to the technical field of aluminum electrolysis production. Background technique: [0002] During the production of aluminum electrolytic cells, metallic aluminum precipitates and accumulates on the cathode at a certain speed. In order to maintain the best production technical conditions, the primary aluminum produced should be taken out regularly (generally once a day for large-scale prebaked aluminum electrolytic cells). Therefore, aluminum tapping operation (ie TAP operation) is one of the important routine operations of aluminum electrolytic production. The quality of its operation, especially the grasp of the suction accuracy, will have a direct and important impact on the production and operation of the aluminum electrolytic cell, the completion of technical and economic indicators, ...
