Sichuan Aostar Smelter In China

Sichuan province is the richest province for its waterpower resource in China, perfectly suited to develop a high consuming energy industry. Sichuan Aostar Group Company has two Aluminum smelters, Guangyuan Aostar smelter and Sichuan Aostar Smelter. The production capacity of Aostar Group was 240,000 tons in 2004. The construction scale of Sichuan Aostar Aluminum smelter is 250,000 tons per year. The first 168 GY-300KA pre-baked anode cells (125,000 tons/year) were put into production in 2003. This company has taken the lead in the use of the transfer gantry technology in China. Besides making the process of calibration the pot shell it has concentrated the efforts to construct cell lining elsewhere. This company also has taken the lead in China for using the EIRICH force mixing and cooling technology as well as in the world for the CP Company?s vertical ball mill technology that produces the pre-baked anodes. The carbon anode system completed its 190,000 tons/year production scale. This is the most advanced technology and the biggest scale pre-baking anode manufacture in China. Since the Sichuan Aostar 300KA cell was put into production, it runs normally and smoothly. Up to now the current efficiency is higher than 94% and the specific energy is only 13300kWh/T-Al.
