Abstract: According to the technological conditions and characteristics of the spraying system of the wet air cooler in steel plants, corrosion and scale inhibitors with excellent capabilities have been selected, through scale and corrosion tests and dynamic simulation experiments. Based on the actual situation of the worksite, the project has thoroughly solved the scaling problem of the wet air cooler after one-year application, by changing the make-up water from river water to soft water, adding specified corrosion and scale inhibitors, and using biocide synergistically. It can be assured that the air cooler can work chronically, steadily, and safely.

Key words: air cooler, spraying water, process characteristics, soft water, corrosion and scale inhibitors
