Steel silos are mainly used to store cement, fly ash, slag powder, clinker, grain and other powder and granular materials. In 2013, it has been successfully used for the storage of liquids such as sulfuric acid.
The prefabricated steel silo is referred to as the assembly silo. It is a kind of steel silo formed by punching a corrugated plate by mechanical rolling and molding, and then assembling it through a high-strength bolt connection with an electric torque wrench. The wall plate of the assembly silo is corrugated, and the plate is generally made of galvanized plate, whose thickness is usually 0.8 to 4.2mm, and the thickness of the silo wall can reach 8.4 mm. Most of the corrugated wall panels use the rolling process, which is mass-produced by a mechanical forming production line. The production line can automatically produce corrugated plates of various specifications. The advantages of the rolling method are that the wave shape is formed successively, the internal stress can be eliminated, the resilience is small, and the quality of the produced plate is better. Even thicker steel plates can be formed in sequence on the forming unit assembly line. In addition, the forming unit and supporting equipment such as uncoiler, leveling machine, conveying roller table and hydraulic fixed-length flying shear can directly process the coil into corrugated steel plate products with required specifications.
