Production Status Of Galvanized Steel Plate Jun 08, 2017

   In 1937 the United States established the first continuous hot-dip galvanized steel production line, in 1942 in the United States built the first continuous galvanized steel strip production line, from entering the industrial production has been 70 years of production history. Hot galvanized products are widely used in construction, home appliances, travel, container manufacturing, electrical and mechanical industry, covering almost all areas of basic necessities. In recent years, the world demand for galvanized steel is increasing, the output growth is also very fast, in the United States, Japan and other steel production power, hot galvanized steel plate in the proportion of steel has been as high as 13% -15%.Galvanized Steel Sheet

    Recently, the automotive industry is paying more and more attention to the service life of materials, with cold-rolled steel coating has been unable to meet the requirements of corrosion resistance. In this case, excellent corrosion resistance and low cost of hot galvanized sheet began to generally favored by the car manufacturers.Galvanized Steel Sheet

    The greatest advantage of the coated steel sheet is excellent corrosion resistance, paintability, decorative properties and good formability. In recent years, the amount of coated steel plate in the car has been on the rise, and become the main body of automotive sheet. Countries around the world are studying how to expand the coating plate varieties, specifications, improve the coating process and then improve the quality of the coating, that is, corrosion resistance, anti-powder peeling, coating, welding. The formability of the coating plate is always an important aspect of its application, which depends on the substrate performance, coating process and performance and forming process conditions, through the combination of advanced technology to achieve a good application effect.Galvanized Steel Sheet

    China's hot-dip galvanizing production development has been lagging behind. In the 1950s and 1960s, 13 single-plate slag flux hot-dip galvanizing units were built with a capacity of 100,000 t / a. However, due to low yield, high cost, poor quality, polluted environment and poor economic efficiency. Has stopped, converted production. From the late 1970s, China began to build large-scale broadband hot-dip galvanizing unit.

    Hot-dip galvanized steel in China's market has been a shortage of varieties. Since the mid-90s of the 20th century, every year from abroad to import 80-100 million t or so. With the development of the domestic economy, especially the development of automobiles, home appliances and construction industry, the demand for galvanized steel is also greatly increased. China has completed a number of annual production capacity of more than 100,000 tons of production lines, but from the process, equipment to product varieties are low-level traditional technology of hot-dip galvanizing unit, the quality of the variety can not meet our country Economic construction and development needs, still need to build a new hot galvanized line to meet the needs of the market.Galvanized Steel Sheet
