Sheet of galvanized

Sheet of galvanized is a type of steel plate coated with a layer of zinc on its surface, mainly used to prevent corrosion of the steel plate surface and extend its service life. The following is a detailed analysis of the production and development of sheet of galvanized metal:

1. Production Status

1. Process technology and equipment
The production process of sheet of galvanized mainly includes raw material preparation, surface treatment, galvanizing treatment, quality inspection, cutting and forming. Among them, galvanizing treatment is a key step, usually using two methods: hot-dip galvanizing or cold galvanizing, with hot-dip galvanizing being more commonly used.
In terms of equipment, hot-dip galvanizing units are developing towards high production capacity, specialization, and high efficiency. For example, using a tower furnace requires higher investment compared to a horizontal furnace, but it has the advantages of good airtightness, fewer furnace rollers, longer lifespan, and lower maintenance costs, which are beneficial for improving plate shape and shortening furnace length. At the same time, the efficiency of the heating furnace is continuously improved by using heating exhaust gas to preheat hot strip steel to save energy. Heating technologies such as drum pumping pulse control burner and multi-stage combustion radiation tube are adopted to improve the adjustment range of the burner and the life of the radiation tube, which is beneficial for the uniformity of heating and can reduce NOx content, which is beneficial for environmental protection.
2. Production and market demand
In recent years, with the development of the domestic economy and the growth of the automotive, home appliance, and construction industries, the demand for galvanized steel strip has greatly increased.
The hot-dip galvanizing industry in our country has entered a new stage of high-speed and sustainable development, but there are still some products that rely on imports, and there are few high-end domestic brands. Meanwhile, influenced by relevant national policies and market conditions, the existing production lines will experience a certain degree of concentration and integration, and the focus of new production lines will gradually shift to the central and western regions.

3. Product Quality and Standards
The quality standards for sheet of galvanized mainly include packaging, specifications and dimensions, surface, galvanizing amount, and machine performance.
Although China has made significant improvements in the production, product quality, process technology, and equipment level of sheet of galvanizeds, there are still problems such as significant differences in equipment level, excess production capacity, and private enterprises not producing according to standards.

2. Development Trends

1. Technological innovation and process improvement
With the continuous improvement of technology, the production technology of sheet of galvanized metal will continue to innovate. For example, the application of new galvanizing processes, material improvements, and the development of environmental protection technologies will further enhance the quality and performance of galvanized sheets, meeting market demand.
Continuously improving galvanizing equipment, including air knives, sinking rollers, stabilizing rollers and ancillary equipment, zinc pots and galvanizing equipment, etc. Enable the air knife to automatically track the strip steel and maintain a stable distance from it; Capable of overall assembly and adjustment, with accurate positioning mechanism; It can achieve dynamic control of stable pressure in the nozzle area.
2. Optimization of market demand structure
With the increasing demand from consumers for product quality and environmental performance, the demand structure of the sheet of galvanized metal market is gradually optimizing. High quality and high-performance galvanized sheet products are favored by the market, and the demand for low-quality products is gradually decreasing.
3. Increased concentration of industries
The sheet of galvanized metal industry is showing a trend of gradually increasing industrial concentration. Some large steel companies have invested heavily in technological transformation and capacity expansion in the field of galvanized sheet, enhancing their market competitiveness.
4. International market competition and cooperation
China is the world's largest producer and consumer of sheet of galvanizeds, but the international market competition is fierce. China's sheet of galvanized industry has strong competitiveness. With the promotion of the "the Belt and Road" initiative and the liberalization of international trade, the competitive advantage of China's sheet of galvanized products in the international market will be further highlighted.
In summary, the production and development of sheet of galvanized metal are influenced by various factors. In the future, with technological innovation, optimization of market demand structure, increase in industrial concentration, and deepening of international market competition and cooperation, the production and application of sheet of galvanized metal will usher in a broader development prospect.
