委内瑞拉国家铝工业一直致力于大电流电解槽的研究和开发,由于委内瑞拉在铝的生产方面具有许多竞争的优势,如铝矾土资源丰富、低成本电力和优越的地理位置,所以,对于新建炼铝厂来说有着巨大的吸引力。在20世纪80年代就建议将国家炼铝生产能力提高到200万吨/年,目前正在积极寻求投资,用于现有的炼铝厂或新建炼铝厂。 铝的冶炼是在电解槽中进行的,原料是氧化铝、碳和电能,电解槽的产量和工作电流成正比。为此,委内瑞拉铝工业的专家们开展了以提高电解槽产量为目的的大电流电解炼铝新工艺—V—350电解槽,电解槽在320～350千安下工作。 V—350电解槽采用大电流,可以节省生产和投资成本,提高炼铝厂的生产潜力。由CVG-Venalum开发研制的大
The Venezuelan national aluminum industry has been working on the research and development of high-current electrolyzers. As Venezuela has many competitive advantages in the production of aluminum, such as bauxite, which is rich in resources, low-cost electricity and has excellent geographical location, Aluminum has a huge attraction. In the 1980s, it was proposed to raise the national alumina production capacity to 2 million tons / year and is now actively seeking investment for existing aluminum smelters or new aluminum smelters. Aluminum smelting is carried out in the electrolytic cell, the raw material is alumina, carbon and electric energy, electrolytic cell output and operating current is proportional. To this end, the Venezuelan aluminum industry experts to carry out the production of electrolytic cells for the purpose of high-current aluminum electrolysis new process-V-350 electrolyzer, electrolysis cell at 320 ~ 350 kA work. V-350 electrolyzer with high current, can save production and investment costs, improve the aluminum smelter’s production potential. Developed by CVG-Venalum large
