Types, processing methods and production capacity of aluminum and aluminum alloy processing products
ã€China Aluminum Network】 China's 2002 average aluminum alloy casting rate of 92.53%, the finished product rate of 73.99%, 69.87% of the total aluminum finished product yield, aluminum processing metal consumption 1047.03kg / t, comprehensive power consumption 1620.14kW h/t, comprehensive energy consumption 1164.41kg/t. For pure aluminum and soft alloy series aluminum foil and foil production, the domestically more advanced enterprises have about 80% of finished aluminum sheet and strip processing, about 75% of general level companies, and 60% to 70% of backward companies. According to the type, hot-rolled sheet: 80% to 85%, cold-rolled sheet: 70%, skin sheet: 23%, foil yield: 58% to 59% (0.007mm), 62% to 63% (0.02 Mm). In 2002, the average fused cast product rate of China's aluminum industry enterprises was 92.53%, the finished product yield was 73.99%, the total finished product rate of aluminum processing materials was 69.87%, the aluminum processing metal consumption was 1047.03 kg/t, and the comprehensive power consumption was 1620.14 kWh/t. Energy consumption 1164.41kg/t. For pure aluminum and soft alloy series aluminum foil and foil production, the domestically more advanced enterprises have about 80% of finished aluminum sheet and strip processing, about 75% of general level companies, and 60% to 70% of backward companies.

At present, aluminum processing companies in developed countries have greatly improved labor productivity by adopting highly efficient equipment and organizing specialized production. The per capita production capacity of Nippon Light Metals' Nagoya Rolling Plant is 142.86t/a; the average labor productivity of Japan's Donghai Aluminum Foil Factory is 72t/a; the per capita labor productivity of the Guspen Aluminum Rolling Mill is 250t/a. Labor productivity of some large aluminum processing companies in China in 2000.
