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 disclosure proposes an image recognition-based blast furnace slag centrifugal granulation particle size detection system and method. The detection system includes a control unit, a slag extraction device, and an image acquisition unit. The image acquisition unit collects the image of the slag particles, and the control unit detects and analyzes the size of the slag particles according to the collected image to obtain the detection data of the slag particle size; the control unit is respectively connected with the slag extraction device and the image acquisition unit. The disclosure collects images of slag particles by setting an image acquisition device, and obtains the size data of slag particles after image analysis, adopts a soft measurement method to overcome the technical problem that blast furnace slag particles cannot be measured in real time due to high temperature, and improves the centrifugal force of blast furnace slag. Real-time and accuracy of particle size measurement. According to the data of slag particle size, the blast furnace slag granulation device can be regulated in real time to control the particle diameter in real time and ensure the heat recovery efficiency of liquid slag mechanical centrifugal granulation.
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...
