国内汽车板的生产现状及对生产装备的需求

汽车板作为制造汽车用主要材料，应具备很好的刚性、成形性、耐蚀性、焊接性等特点。如今，消费者对汽车在安全、节能、耐用、外观等方面有了更高的要求，这其中，为了减重节能而大量采用高强度钢板和高强度变截面板，以及为提高耐蚀性而大量采用镀锌钢板等已成为汽车板今后发展的主要方向。与此相适应，用于生产汽车板的轧机生产线应具备更高的性能以适应生产高强钢的需要，而镀锌机组不但应具备生产高强度镀锌板的能力，而且应尽早实现电镀锌机组的国产化。

Domestic Current Status of Automobile Sheets and Demand on Production Equipment

As a main material to build automobiles, the automobile sheet shall have high stiffness, formability, corrosion resistance and weldability. Today, customers have stricter requirement on the safety, energy-saving, service durability and appearance of automobiles. High-strength steel plates and high-strength variable cross-section steel plates used in a large amount to reduce the weight of automobiles and galvanized steel plates used in large amount to increase the corrosion resistance are main tendency of future automobile sheet development. For this purpose, the rolling mill to produce automobile sheets shall have suitable capacity to produce high-strength steel plates. The galvanizing plate mill shall not only have the capacity to produce high-strength galvanized plates but also be built independently by the builders in China.
