Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0033]The invention provides an intelligent control system for ladle bottom argon blowing based on visual recognition. The system can not only identify the slag surface of the ladle in real time, realize the automatic quantitative detection of the argon stirring effect, but also apply the adaptive control to the bottom blowing control, which can greatly reduce the influence of nonlinearity and u...

Abstract

The invention discloses a steel ladle bottom argon blowing intelligent control system based on visual identification, and belongs to the field of ferrous metallurgy automatic control, and aims to identify the ladle slag surface in real time, realize automatic quantitative detection of the argon stirring effect, apply self-adaptive control to bottom blowing control, greatly reduce the influence ofnonlinearity and uncertainty on control in the ladle bottom argon blowing process and realize accurate and automatic regulation and control of argon. Besides, real-time prediction perception can be performed on an intelligent regulation and control model and control, main variable state estimation, error analysis, fault diagnosis and the like in the ladle bottom argon blowing control process through deep learning so that intelligent prediction of the argon blowing process and control can be achieved.

Description

technical field [0001] The invention belongs to the field of automatic control of iron and steel metallurgy, and more specifically relates to an intelligent control system for blowing argon at the bottom of a ladle based on visual recognition. Background technique [0002] Refining outside the furnace has become an important part of the production process of modern steel mills. It is an important means to produce pure steel and ensure the smooth progress of continuous casting. The argon blowing system at the bottom of the ladle is the most widely used external refining method at home and abroad because of its simple equipment, low operating cost and good refining effect. It can not only effectively uniform the composition and temperature of molten steel, but also remove the inclusions, improve the quality of molten steel. If the argon blowing flow rate is too high, it will blow through the liquid surface and cause splashing, which will cause the molten steel to be exposed a...
