Electrolytic Aluminum Process
The process of aluminum electrolysis process: modern aluminum industry production by cryolite alumina by molten salt electrolysis. Molten cryolite is solvent, alumina as solute, with carbon as the anode, aluminum melt as cathode, powerful DC. In 950 -970 DEG C, poles in the electrolytic cell for electrochemical reaction. The chemical reaction was carried out by the equation: 3O2 2Al2O3==4Al.
2O2 - -4e - =O2: anode cathode: Al3 3E = - =Al. The anode products are carbon dioxide and carbon monoxide gas, which contains a certain amount of hydrogen fluoride and other harmful gases and solid dust. To protect the environment and human health need to purify the anode gas, remove harmful gas and dust into the atmosphere. Catholic product is the liquid aluminum and aluminum liquid by vacuum lift bag out from the groove and sent to the foundry, in the holding furnace by purification after clarification, cast into ingots or directly processed into wire blank.
