钢结构具有强度高、重量轻、便于制作安装和施工速度快等优点,在工业建筑中的使用量逐年增加。冶金部近几年来建设的引进工程,大量采用了钢结构。如已经建成的武钢一米七轧机工程,建筑钢结构用量8万多吨,正在兴建的宝钢工程,建筑钢结构用量近30万吨。但应用钢结构存在锈蚀与防锈问题,一般的防锈方法采用油漆防护。对于油漆工程质量较差的钢结构厂房,建成后
The steel structure has the advantages of high strength, light weight, ease of manufacture, quick installation and construction, etc. The usage in industrial buildings increases year by year. The introduction project of the Ministry of Metallurgy in recent years has adopted a large number of steel structures. For example, the WISCO one-meter-seven-thousand-mill operation has been completed, and the amount of steel structure used for construction is more than 80,000 tons. The Baosteel project that is under construction has a construction steel structure usage of nearly 300,000 tons. However, there are rust and rust problems in the application of steel structures, and general rust prevention methods use paint protection. For steel structure workshops with poor paint engineering quality, after completion
