Problems solved by technology
[0006] In order to solve the above problems, the present disclosure proposes a method and system for detecting the particle size of centrifugal granulation of blast furnace slag based on image recognition. By setting up an image acquisition device to collect images of slag particles, the data of the size of slag particles can be obtained after image analysis. The soft measurement method overcomes the technical problem that blast furnace slag particles cannot be measured in real time due to high temperature, and improves the real-time and accuracy of blast furnace slag centrifugal granulation particle size measurement

The invention discloses a blast furnace slag centrifuging and pelletizing particle size detecting system and method based on image recognition. The detecting system comprises a control unit, a slag taking device and an image acquisition unit, wherein the slag taking device carries out sampling on slag particles obtained after the blast furnace slag is centrifuged and pelletized; the image acquisition unit collects the images of the slag particles; the control unit detects and analyzes the sizes of the slag particles according to the collected images to obtain the detecting data of the sizes ofthe slag particles; and the control unit is connected with the slag taking device and the image acquisition unit. According to the detecting system, the image acquisition unit is arranged to collectthe images of the slag particles, the data of the size of the slag particles is obtained after image analysis, the soft measurement method is adopted to solve the technical problem that the particlesof the blast furnace slag cannot be measured in real time due to high temperature, and the real-time performance and the precision of blast furnace slag centrifuging and pelletizing particle size measurement are improved. A blast furnace slag pelletizing device can be adjusted and controlled in real time according to the size data of the slag particles to control the particle diameter in real timeand ensure the heat recovery efficiency of mechanical centrifuging and pelletizing of liquid-state slag.
Description
technical field [0001] The present disclosure relates to the related technical field of blast furnace slag processing, specifically, to an image recognition-based blast furnace slag centrifugal granulation particle size detection system and method, and to the real-time measurement of particle diameter during the mechanical centrifugal granulation process of liquid molten slag. detection. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Iron and steel is a pillar industry of my country's national economy. During the ironmaking process, a large amount of by-products of blast furnace slag will be produced. According to research, about 0.3 to 0.4 tons of blast furnace slag is produced for every ton of pig iron produced. The temperature is about 1500 ° C, which has It has the characteristics of large output and high heat. At the same time, th...
