Description

Technical Field

[0001] The utility model belongs to the field of water treatment for thin strip casting and rolling, in particular to a drug adding device for a water treatment system for thin strip casting and rolling. Background Art

[0002] The thin strip casting water treatment system mainly processes the parameters such as PH, hardness, turbidity, and conductivity of the production water to meet the production needs. The cooling water of this water system is used for casting rolls and RH. The circulating water treatment of the closed-loop crystallizer soft water system is divided into two parts: first, the soft water circulating water treatment of the crystallizer; second, the circulating cooling water treatment of the surface evaporative air cooler. First of all, the crystallizer softened water circulating water treatment is analyzed. Softened water removes the hardness, making the water highly corrosive, which can cause serious corrosion to the pipelines, heat exchange equipment and heat exchange tubes of the surface evaporative air cooler in the circulating water system. Therefore, the treatment of this water is mainly corrosion inhibition, taking into account the control of slime and dirt, especially the rust formed by some corrosion products, which should be strictly controlled. If the water quality is not treated, it will turn black and smelly after use, and the pipeline will be severely corroded. Therefore, it is necessary to use scale inhibitors and corrosion inhibitors together with membrane repair agents to ensure water quality and thus ensure the quality of steel production.

[0003] Most of the current dosing methods are to manually add the chemicals into the device barrel, and then transport the chemicals into the pipeline through mechanical pumps. The dosing process is not only time-consuming and labor-intensive, but also has poor water treatment and energy-saving effects, leading to serious pipeline corrosion. Utility Model Content
