Description

Technical Field

[0001] The utility model relates to the field of detection equipment, in particular to an online detection device for hydrochloric acid concentration. Background Art

[0002] In steel mills, hydrochloric acid is mainly used in the pickling process. In this process, the concentration of hydrochloric acid plays an important role. Hydrochloric acid can help remove the iron oxide scale on the surface of steel. During the steel production process, iron oxide scale will be produced on the surface of steel. These iron oxide scales are not soluble in water, so they cannot be simply washed away with water. When the steel is soaked in hydrochloric acid, the various components in the iron oxide scale will undergo a series of chemical reactions with the hydrochloric acid, thereby removing it.

[0003] Therefore, the concentration of hydrochloric acid is very important. At present, the method of detecting hydrochloric acid in steel rolling mills still relies mainly on manual labor. Workers take samples of hydrochloric acid in the hydrochloric acid pool, put them into test tubes, place indicators, and then use sodium hydroxide solution of known concentration for detection. The process is very complicated. Any errors in the steps during the detection will lead to errors in the detection concentration, resulting in heavy workload for workers and inaccurate data records.

[0004] Therefore, the utility model provides an online detection device for hydrochloric acid concentration to solve the problems raised in the above background technology. Utility Model Content
