The embodiment of the invention discloses an early-warning method and device for deviation of strip steel on a cold rolled galvanizing line. The method comprises the following steps: acquiring strip steel position deviation values from N furnace-front deviation correcting sensors in M furnace-front deviation correcting sensors when the strip steel runs on the cold rolled galvanizing line so as to obtain N strip steel position deviation values of N positions in front of an annealing furnace; determining whether the N strip steel position deviation values are within the corresponding preset deviation range; and if any one of the N strip steel position deviation values is beyond the corresponding preset deviation range, sending out strip steel deviation early-warning information, wherein for the N furnace-front deviation correcting sensors, preset deviation ranges are correspondingly set. With the adoption of the method and the device, the technical problem of low capacity of correcting the deviation in the annealing furnace on the cold rolled galvanizing line can be solved; the deviation degree of the strip steel in the annealing furnace can be reduced, and moreover, the strip steel deviation in the annealing furnace can be timely handled, so that stable travelling of the strip steel in the annealing furnace is ensured, and as a result, the galvanizing line output and the product quality can be improved.

The invention discloses a product detection method of an organic electrochemical ammonia synthesis reaction system. The method comprises: carrying out the conventional indophenol blue method test on the electrolytic solution of the organic electrochemical ammonia synthesis reaction system to obtain a color-developing solution; performing ultraviolet spectrophotometric analysis on the color-developing solution to obtain a full-spectrum curve, taking the absorbance value, and calculating the product ammonia content. In the present invention, the product detection method is the optimized indophenol blue colorimetric method, and the organic electrolyte pretreatment and the ultraviolet absorption spectrum analysis are two-pronged, eliminating the baseline shift problem that sometimes occurs due to the optical fiber design of the ultraviolet spectrophotometer, thereby reducing due to Possibility of overestimating ammonia concentration due to baseline shift.

The invention can be used for ammonia product detection in an organic system.

The invention discloses a control method for preventing strip breakage in the annealing furnace of a cold rolling processing line. A backup protection function is added to the original correction system. Ramp speed limit, early warning prompt system, tension compensation system control, when the strip steel deviates from the production center line by 50mm, the starting ramp speed limit is 60m / min, even if the shape of the incoming material is poor, the degree of deviation of the strip steel can be significantly reduced. It effectively avoids the serious deviation of the strip in the furnace, and at the same time greatly reduces the accident of strip breakage in the annealing furnace, so that the continuous and reliable operation of the cold rolling processing line is guaranteed.
