Abstract

The invention relates to a liquid level control system and liquid level measuring method based on oblique photography, wherein the liquid level control system comprises a nozzle bag; a nozzle bag cover is set on an upper portion of the nozzle bag; the nozzle bag cover is provided with a glass observation window; the glass observation window is provided with a scale; the liquid level height inside the nozzle bag and the inner wall of the nozzle bag are formed a liquid lever cross line; the scale is parallel to the liquid level cross line; a CCD camera is set above the nozzle bag in an inclined way; the liquid level cross line inside the nozzle bag is captured through an optical shaft of the CCD camera by penetrating through the glass observation window; the liquid level cross line, the scale and the lens focus of the CCD camera are in the same surface; a data transmission line is connected between the CCD camera and a PC machine; and the glass observation window is an oval shape. According to the invention, the liquid level control system and liquid level measuring method provided herein has the advantages of high measuring accuracy, rapid measuring speed, simple structure, easy removal and installation and low cost; the surface of an amorphous thin belt is bright; the figure of the fish scale is not obvious; and the quality of the amorphous thin belt is improved.

Description

technical field

[0001] The invention relates to a liquid level control system and a liquid level measurement method based on oblique photography, and belongs to the technical field of amorphous thin strip processing. Background technique

[0002] Amorphous ribbons were prepared by rapid solidification (cooling speed 10 6 °C / s) planar flow casting technology, the high-temperature molten steel is sprayed onto the surface of the high-speed rotating cooling roll through the slit. On the diameter cooling roll, all the factors restricting the performance of the thin strip will be more concentrated, complex and difficult to control. At present, most of the amorphous strip throwing equipment with a high degree of automation control is manufactured abroad, and amorphous and nanocrystalline thin strips occupy nearly 70% of the domestic market. At the end of the "Twelfth Five-Year Plan", a number of 10,000-ton amorphous strip production lines were put into operation, but the automati...
