ている。Rusted or discolored steel sheets cause a reduction in product yield due to cutting of defective parts (the defective rate may reach several percent) and increase in process costs due to re-cleaning, resulting in large losses. Defective products mainly occur during low-speed operation or when the line is stopped. As countermeasures against these problems, the above-mentioned problems have been alleviated by making continuous pickling and cold rolling using a looper, and continuous annealing equipment called CAL and C-containing circle 4.

When added at a high concentration, they alone exhibit the effect of preventing discoloration of steel sheets, but when used in combination with cyclohexylamine, the effect is exhibited even at extremely low concentrations of carboxylic acid, oxycarboxylic acid, or their salts. When these carboxylic acids, oxycarboxylic acids, or their salts are added in high concentrations, carbon stains occur during annealing in the subsequent process, causing defects in chemical conversion treatment and plating, so it is necessary to keep the concentration as low as possible, but cyclohexyl Combination use with amines solves such problems.

噴霧するなどの方法が採用可能である。During low-speed operation or when the line is stopped, the locations where steel plates rust or discolor are generally the water sprinkling area after chemical or electrolytic cleaning, inside the cleaning tank, and from the outlet of the cleaning tank until drying. Therefore, in order to prevent rusting and discoloration that occur in such places, it is effective to add an anti-discoloration agent to the cleaning water, and it is also recommended to use this cleaning water for spraying chemicals or water after electrolytic cleaning. Effective. The next best method is to apply or spray an anti-discoloration +1 agent to the water spraying area after chemical or electrolytic cleaning. For example, cleaning water containing an anti-tarnishing agent is pumped up and sprayed. Alternatively, a method such as directly spraying the discoloration preventive agent 1F can be adopted.
