Overview Of The Development Of Hot Dip Galvanized Steel Sheet
At present, the Chinese steel industry still has a particular gap with the world's advanced level in terms of variety, quality, cost, service, and labor productivity. In the face of increasingly fierce international and domestic market competition, it is necessary to speed up the pace of structural adjustment. This is the survival of the Chinese metallurgical industry and the development trend of the world's metallurgical industry. Hot-dip galvanizing was invented in the middle of the 18th century, and it developed from the hot-dip galvanizing process. After 50 years of development, steel strips' continuous hot-dip galvanizing process has become a mature and technologically advanced industrial technology. So far, hot-dip galvanizing is still the most common and effective process used in steel corrosion protection methods. Measure. In the construction industry, it is used for light steel keels, building layer panels, corrugated boards, rolling doors, etc. in various industrial and civil buildings; in household appliances and light industry, it is used for the shells and bottom plates of various household appliances; galvanized steel plates are widely used. It uses light, home appliances, automobiles, and the construction industry. It is used for the outer shell, inner panel, bottom plate, etc., of the car body in the automobile industry. My country vigorously develops power, transportation, communications, energy, and urban infrastructure. With the vigorous development of the construction, home appliances, and automobile industries, my country's galvanizing industry faces unprecedented opportunities and a vast market.
Continuous hot-dip galvanizing technology, equipment, and corresponding control methods have extensively developed in the past two decades. The galvanized sheet can meet the demanding requirements of automobile panels and household appliances. It compares with the demanding requirements of automobile panels and household appliances electro-galvanized alloy steel strip. Moreover, it is cheap, has excellent corrosion resistance, and has excellent potential for substitution. This project intends to learn from foreign advanced high-performance automotive hot-dip galvanized production technology and equipment development technology and experience, through technological innovation, optimized design, precision manufacturing, and foreign technical cooperation, to break through the restrictions on my country's high-performance automotive hot-dip galvanized steel production technology And equipment development bottlenecks. At the same time, it discusses the critical significance and prospects of developing hot-dip galvanizing technology in the sustainable development of the national economy, energy conservation, and minerals.
