以下型号均: 29 (25) Abstract — The standard electrode potential of zinc is negative to that of iron, which can protect the steel base in wet environment. Therefore, zinc ting technology has been widely used in the field of corrosion protection. Hot-dip galvanizing process has become the mainstream galvanizing technology because of its low cost, high quality and simple process. However, hot-dip galvanizing process requires higher control of temperature and production process speed. Only advanced control technology can meet the control requirements of the new process. This er designs a control system of hot dip galvanizing production line based on Siemens S7-400 PLC, which ys an important role in improving production efficiency and product quality.
