       At present, the production capacity of ingot hot rolled billets in the world accounts for about 80% of the total billet supply capacity, and continuous casting strips only account for 20%; in China, due to historical and investment reasons, aluminum strip foil (Wuxi aluminum sheet) Most of the processing enterprises use casting and rolling billet. The current casting and rolling capacity accounts for more than 40% of the total billet capacity, and the proportion is too large. This results in fierce competition for the same grade and the same variety of products. fully use. Hot-rolled coil feeding method, large production capacity, can produce all grades of aluminum alloy; the product has excellent internal organization and performance, good surface quality, and can be adapted to all aluminum sheet and foil consumption fields. Therefore, the production of high-precision aluminum sheet and strip is almost entirely in the production of hot-rolled billets.

       In general, China's general aluminum strip products have excess capacity, but the high-precision aluminum sheet and foil products with large market demand are large, and it is necessary to rely on imports. At present, China is in the midst of a new round of aluminum strip project construction. The large-scale construction projects mainly include: 1+4 hot rolling project of Nanshan Group, the first phase production scale is 200,000 t/a; Asian aluminum hot rolling project The production scale is 400,000 t/a; Alcoa Bohai 1+3 hot rolling project, with an additional capacity of 150,000 t/a; Hunan Yitong 1+1 hot rolling project, with a production scale of 220,000 t/a; Qinghai Pingan Aluminum 1+3 hot rolling project with a production scale of 200,000 t/a; Chinalco Henan Aluminum Co., Ltd. (Luoyang hot rolling project, cold rolling project and Zhengzhou cold rolling project) with a production scale of 200,000 t/a . According to incomplete statistics, the total capacity of new aluminum strips (Wuxi aluminum sheets) currently under construction is nearly 1.5 million t/a. In addition, there are some large-scale projects that are undergoing preliminary work, such as the medium-thick plate project of Northeast Light Alloy, the cold-rolling project of Southwest Aluminum, the aluminum strip project of Fujian Ruiqi, the aluminum strip project of Northwest Aluminum, and the hot rolling of southwestern Guangxi. For projects, etc., the scale of production of these proposed large-scale projects is about 1 million t/a.
