Embodiment Construction

[0044] The present invention will be further described below in conjunction with embodiment.

[0045] like figure 1As shown in Fig. 2, a fixed frame is welded at appropriate parts on both sides of the inner and outer arcs of the foot roll area of ​​the continuous casting machine, and a color area array CCD camera is respectively installed at a designated position about 3m away from the foot roll. Full image of the cast strand. The camera is aimed vertically at the monitoring point (surface) as much as possible, and the deviation angle is controlled within 0°~30°. There is a protective cover outside the camera, and there is an N 2 Gas blown to seal. The color image acquisition card is selected, and the sampling speed of 24bit images at 25 frames per second can be realized at 800×640 resolution and transmitted to 3 industrial computers. In addition to collecting video image data in real time, the industrial computer can also communicate directly with the on-site PLC equipmen...

Abstract

The invention belongs to the technical field of steelmaking continuous casting, in particular to an online monitor of a continuous casting machine crystallize foot roll working state and a monitoring method thereof. The monitor comprises minitype CCD cameras, a video image acquiring module and an industry computer, wherein the minitype CCD cameras are arranged at the inner arc side and the outer arc side of a continuous casting machine foot roll area and is used for acquiring bi-dimensional image information; the video image acquiring module is used for receiving and storing the bi-dimensional image information; and the industry computer is used for processing and analyzing the bi-dimensional image information and display the final result. By installing the CCD cameras at the inner arc side and the outer arc side of the foot roll area and adopting the computer image processing technology to perform online image analysis on foot roll rotation condition and slag adhering condition, the working state of the foot roll can be monitored in real time, and alarm or corresponding fault treatment can be carried out timely based on the characteristics of abnormal conditions in necessity. The invention has the advantages of simple device structure, wide application range, realized remote monitoring by the image pickup technology, lowered labor intensity and danger level for field workers and improved whole automation level and intelligence level of the continuous casting machine.

Description

technical field [0001] The invention belongs to the technical field of steelmaking and continuous casting, and in particular relates to an online monitor for the working state of a foot roll of a crystallizer of a continuous casting machine and a monitoring method thereof. Background technique [0002] The foot roller is an important part of the continuous casting machine. It is generally installed at the lower part of the mold. Its functions are mainly reflected in: (1) guiding the dummy bar into the mold to prevent the dummy head from damaging the copper plate of the mold ( (2) Support and guide the weak slab shell that first exits the mold to reduce the deformation or breakout of the slab, and at the same time reduce the impact of the slab on the copper plate ( Tube) lower mouth wear. In the early days, there was still controversy in the continuous casting industry about whether it was necessary to install foot rolls in the mold. The focus of the controversy was that the...
