Blast furnace ironmaking is the most important way of ironmaking in China, and the raw materials must go through a process called sintering before entering the blast furnace. Before sintering, the raw material needs to be prepared. Due to the different particle sizes of the alloy ore used to prepare the sintering raw materials, it cannot be directly used in production, and the particle size distribution of the alloy ore will directly affect the subsequent smelting process, including smelting temperature, metal yield, etc. The control of the particle size helps to improve the stability of the smelting process. A stable production process can reduce the uncertainty in production and improve the robustness of the production line. Therefore, it is necessary to have a set of alloy ore particle size detection system, which can quickly realize particle size screening.
At present, the particle size detection of alloy ore mainly adopts the method of manual screening and sampling to count the size distribution of coke carbon materials, and the statistical results are rough, the sampling efficiency is low, and the labor intensity of workers is high, and it cannot be completed automatically. Based on the above problems, the machine vision technology is used to obtain high-definition products by setting up a suitable light source illumination scheme, and then the detection results are obtained by analyzing and processing the products to be inspected, and the particle size detection of alloy ore is carried out.

Alloy ore particle size detection systems typically have the following features:
1. Real-time detection: Different from the traditional manual detection, the alloy ore particle size detection system can monitor the particle size characteristics of the alloy ore in real time, and transmit the current particle size distribution of the alloy ore in real time, and the staff can adjust the particle size distribution;
2. Fully automatic detection: The alloy ore particle size detection system adopts machine vision recognition algorithm, which is fully automated, does not require manual measurement, and is more efficient and intelligent;
3. Particle size distribution analysis: The alloy ore particle size detection system can generate a histogram or curve of alloy particle size distribution to show the distribution of particles of different particle sizes.
4. Report generation: The alloy ore particle size detection system can generate a detailed test report, and the average particle size trend chart of sinter can be displayed, and the trend change of the material can be intuitively observed.
5. Data storage and management: The alloy ore particle size detection system will store the detection results and related data, and provide data management functions to facilitate subsequent query and analysis. You can also export all data or export a single piece of data separately.
6. Simple operation: The whole system usually has a user-friendly interface, easy to operate, and can be used by operators of different technical levels.
The alloy ore particle size detection system finally realizes automatic particle size detection, realizes real-time detection and timely feedback of alloy ore particle size, and the system runs stably and reliably in actual operation, and the screening accuracy is very high, which greatly improves the production efficiency and product quality.
