Galvanized iron barrels can resist water vapor corrosion, but are not resistant to acid and alkali corrosion. When the zinc plating layer encounters acid and alkali corrosion, the internal iron will rust.
Stainless steel is made by adding other metals such as chromium and nickel to iron, which is corrosion-resistant and not easy to rust. According to the proportion of different metals in stainless steel, it is divided into many stainless steel varieties, and their performances are different. Magnetic and non-magnetic, non-magnetic stainless steel basins cannot be used on induction cookers.
After the surface of the galvanized iron drum is smoothed, the flatness of the galvanized sheet has been improved to a certain extent, the wave shape of the galvanized sheet is partially eliminated, and at the same time, the slag particles or other uneven spots on the surface can be flattened to make the surface smooth smooth. Adjust the surface roughness of galvanized sheet. By controlling the roughness of the work roll surface of the finishing machine, the original uneven roughness of the galvanized sheet surface can be unified to a certain range.
