Description

Technical Field

[0001] The invention relates to the field of grasping technology, in particular to a grasping device for a tank cover plate of an aluminum electrolysis tank. Background Art

[0002] Electrolytic aluminum is aluminum obtained by electrolysis. Modern electrolytic aluminum industry production adopts cryolite-alumina molten salt electrolysis. Molten cryolite is the solvent, alumina is the solute, carbonite is the anode, and aluminum liquid is the cathode. After a strong direct current is passed, an electrochemical reaction is carried out at the two electrodes in the electrolytic cell at 950℃-970℃, that is, electrolysis. The anode products are mainly carbon dioxide and carbon monoxide gases, which contain a certain amount of harmful gases such as hydrogen fluoride and solid dust. In order to protect the environment and human health, the anode gas needs to be purified and discharged into the atmosphere after removing harmful gases and dust. The cathode product is aluminum liquid, which is extracted from the tank by vacuum ladle and sent to the foundry. After purification and clarification in the holding furnace, it is cast into aluminum ingots or directly processed into wire billets, profiles, etc.
