SUMMARY:The effect of water quality on quality defects in hot rolling mill coil production
DESCRIPTION:In the iron and steel industry, water is one of the most significant inputs for production. The most common uses of water in the iron and steel industry are product surface cleaning, cooling, protecting equipment and improving working conditions for employees.
The water which uses for surface cleaning contacts with the final products. Therefore, water quality has tremendous importance at this point. The quality of the water that comes into contact with the product can cause undesirable impacts in the quality of the material from time to time. Variables such as the chemical structure of the water, the residence time on the material, and the chemical type used in the treatment of the water affect the product quality.
During the coil production in the hot rolling mill, it was determined that white spots on the coil and in detail examination, the element S broke the layer in the scale and and a white spot formation was detected with Cl reacted with AgNO3. After the occurrence of this situation, the limit values of the circulation water in contact with the product, the water source to be used and the chemical treatment of the circulation water were overhauled, and the problem’s repetition was prevented.

Key Words: Water Quality, Coil Production
