| titleOfInvention | Measuring method of main component concentration of neutral salt electrolytic bath for descaling of stainless steel strip |
| abstract | (57) [Summary] [Purpose] The sodium sulfate concentration and hexavalent chromium concentration, which are particularly important in the composition control of neutral salt (sodium sulfate) electrolytic bath for descaling of stainless steel, can be quickly and easily and frequently or continuously. It also makes it possible to measure. [Structure] Ultrasonic propagation velocity and solution conductivity of a sample bath for measurement obtained by filtering a neutral salt electrolytic bath were measured, and an aqueous solution of sodium sulfate and hexavalent chromium with various known concentrations was measured in advance around the temperature at the time of measurement. The two-dimensional calibration curve showing the relationship between the measurement value set consisting of the measurement values of the ultrasonic wave propagation velocity and the solution conductivity prepared for each plurality of temperatures and the aqueous solution composition represented by the sodium sulfate concentration and the hexavalent chromium concentration, The temperature of the relationship is corrected and the concentration of each component is known. [Effect] The work load required for controlling the concentration of the electrolytic bath is reduced, the bath conditions are easily adjusted, the descaling capability is stabilized, and the quality is improved. |
