钢材腐蚀的损失,每年以百亿卢布计算。因此,钢结构和钢制品的防腐问题具有重大意义。钢材表面热浸镀锌对防腐特别有效。由于这种防腐镀锌工艺过程机械化水平的不断提高,其使用的经济效果逐年增大。除镀锌钢板以外,最近镀锌轧钢在工业厂房和结构物、桥梁、电气化铁路的输电线路和通讯网的电杆、电视塔等结构上的应用量也显著增加。
The loss of steel corrosion is calculated in billions of rubles a year. Therefore, the corrosion of steel structures and steel products is of great significance. Hot dip galvanizing on steel surfaces is particularly effective for corrosion protection. As the level of mechanization of this anti-corrosion galvanizing process continues to increase, the economic effects of its use increase year by year. In addition to galvanized steel sheets, the recent application of galvanized rolled steel in the transmission lines of industrial plants and structures, bridges, electrified railways, and poles and television towers of communication networks has also increased significantly.
