Embodiment Construction

[0023] attached Figure 1-3 It is a specific embodiment of the present invention. The invention is an automatic leveling liquid dosing method based on online conductivity measurement, which includes the following steps: leveling liquid conductivity-concentration relationship model - online conductivity detection - leveling liquid dosing model - dosing execution device; The leveling liquid conductivity-concentration relationship model is described, which mainly characterizes the corresponding relationship between the leveling liquid conductivity and the concentration of different types of leveling liquids under different temperature conditions. It is obtained by regular sampling and testing in the laboratory. Liquid conductivity-concentration relationship curve, c(x)=f(T, K), where c(x)——x model leveling liquid concentration, T——leveling liquid temperature, K——leveling liquid conductivity; The online conductivity detection is to install a conductivity detector and a thermomete...

Description

technical field [0001] The invention belongs to the technical field of leveling liquid dosing, and in particular relates to an automatic leveling liquid dosing method based on online conductivity measurement. Background technique [0002] The wet tempering process is widely used in cold rolling tempering units at home and abroad, and plays an important role in improving the control effect of the tempering machine and improving the quality of the plate surface after leveling. Leveling solution concentration is the key control point of the process, and the leveling concentration control accuracy is the key factor determining the quality of the leveled product. The conventional leveling liquid dosing system usually completes the dosing work by manually controlling the addition ratio of the leveling liquid stock solution and demineralized water according to the leveling liquid concentration obtained by off-line detection. The concentration of the leveling liquid prepared by the...
