Embodiment Construction

[0036] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0037] Such as figure 1 As shown, an automatic press furnace control method in a converter tapping process may include the following steps:

[0038] S1, install industrial infrared camera 13 and common industrial camera 14 to shoot video at the suitable position of converter 6 tapping side and communicate with secondary computer 1, see figure 2 .

[0039] Cameras are installed at appropriate positions on the tapping side of the converter to replace manual visual observation. Specifically, an industrial infrared camera is installed at the top of the higher platform on the tapping side of the converter, and the lens angle and focal length are adjusted to capture the furnace mouth of the converter as clearly as possible during tapping. At the same time, an ordinary industrial camera is installed at a lower position on the tapping side of the convert...

Abstract

The invention discloses an automatic furnace pressing control method and system in the converter tapping process. The automatic furnace pressing control method in the converter tapping process comprises the following steps that an industrial infrared camera and a common industrial camera are mounted in the proper positions of the converter tapping side to shoot videos; a converter automatically tilts according to a set inclination angle duration table; a secondary computer judges the conditions that the liquid level of molten steel is low and slag exists at a tapping hole in the tapping process in real time according to the video, generates a furnace pressing instruction and sends the furnace pressing instruction to a PLC; and the PLC automatically presses the converter after receiving the converter pressing instruction, and the converter cannot be pressed again within a certain time after the converter is pressed. According to the automatic furnace pressing control method in the converter tapping process, provided by the invention, by using the camera to replace manual observation with naked eyes and using video recognition software to replace manual judgment, the liquid level height of molten steel in the converter can be kept proper during tapping of the converter, the slag tapping condition of the tapping hole is reduced, the labor intensity of workers is reduced, and the automation degree and the intelligent level of converter tapping are improved.

Description

technical field [0001] The invention relates to the technical field of converter automatic control, in particular to an automatic press furnace control method and system in the converter tapping process. Background technique [0002] Converter steelmaking is the most important steelmaking method in the world today, and steel production accounts for more than 65% of the world's total steel production. As the market demand for high-quality steel increases, such as automobile plates, high-grade ship plates, electrical steel, stainless steel, etc., the requirements for the cleanliness of molten steel for converter steelmaking are also getting higher and higher, so the content of impurity elements in molten steel should be as low as possible. At the end of converter steelmaking, during the process of pouring molten steel from the converter into the ladle, the slag will also flow into the ladle along with the molten steel, affecting the cleanliness of the molten steel. Therefore,...
