System and method of detection and control of melted iron drossing on the basis of image processing

Abstract

The present invention discloses a system of detection and control of melted iron drossing on the basis of image processing. The system provided by the invention comprises: a foundry ladle containing melted iron and slags; a slag-containing basin disposed beside the foundry ladle for containing the slags; a crawler loader arranged at one side of the foundry ladle; a camera connected with a processor; a display connected with the processor and arranged at an operator's position for reflection of the drossing state of melted iron liquid level; and the processor configured to obtain image information acquired by the camera, perform analysis and process of image information, display on the display and access a drossing standard database. The present invention further discloses a method of detection and control of melted iron drossing on the basis of image processing. According to the invention, a drossing process is monitored in real time, and it is determined on line whether drossing grades reach an expected target grade or not according to a drossing standard database so that manual management is avoided, therefore drossing grades may be not misjudged.

Description

technical field [0001] The invention relates to the field of iron and steel metallurgy, in particular to a detection and control system and method for molten iron slag removal based on image processing. Background technique [0002] With the development of modern industrial production, the requirements for the quality of steel are constantly increasing, that is, the requirements for the purity of molten steel are getting higher and higher. Hot metal pretreatment technology is an important means to improve the purity of hot metal, and has become the main component of the iron and steel metallurgy optimization process. Slag removal is to remove a large amount of high-sulfur slag in the desulfurized hot metal ladle to avoid sulfur return during steelmaking , is the key link to control the total amount of sulfur entering the furnace. [0003] In the desulfurization method in the prior art, the desulfurization operator observes the ladle with the naked eye, and judges the slag r...
