●The new third-generation technology of automatic intelligent coal coke petrographic analysis system! 

Heavy upgrade:

1. Adopt Professor Zhao's new third-generation coal microcomponent intelligent AI recognition algorithm technology! The result is more accurate!

2. Based on the new technology of 21 million pixels, 16-bit precision, 4/3 inch super large CMOS chip detector, the internal jump value is smaller, the single measurement area is larger, and the speed is improved. It solves the technical problems of "similar components are easy to identify and inaccurate" caused by low pixels of similar CCD products (only 1-9 million pixels), small coverage of the measurement area, and large internal single-point jump value!

3. The calibration instrument adopts the new "electronic eye to automatically judge the focal length" technology, which completely eliminates the visual error of the human eye, and solves the problem that the content of the reflectivity map interval of similar products has a large error twice, and the adjacent value range is easy to "move"! Facilitate quick and accurate settlement in coal trading!

4. The new upgrade supports four modes of unattended automatic focus control scanning technology such as "point-based quick scanning + automatic focal length intelligent recognition", which is truly a "high-tech light operation" coal rock suitable for production and use.

5. Innovation in the whole industry: Realize the function of "12 continuous measurement", one-time calibration (automatic positioning, focusing), and continuous scanning of 12 samples. Equipped with 6 types of automatic light sheet forming and 6 types of automatic surface treatment machines, it is very suitable for the use of coal entering the factory.

●Professor Zhao's personal profile

Zhao Junguo, former professor of Liaoning University of Science and Technology. He is the research assistant and closed disciple of Professor Zhou Shiyong, a well-known authoritative expert on coal coke in my country and the founder of "Applied Coal Petrology". He once co-authored the monograph "The Properties of Coking Coal and the Quality of Blast Furnace Coke" with Professor Zhou. In 2010, Professor Zhao successfully developed the world's first truly automated coal rock analysis equipment based on the previous research of Professor Zhou, and put it into production. It has been more than 10 years and has been widely used in nearly 600 coal chemical enterprises including: national arbitration institutions, internationally renowned SGS testing institutions, Angang, Shougang, Wuhan Iron and Steel, etc., and has been widely praised by the market! It is a well-known brand in China's coal industry!

Achievements obtained:

The second prize of Metallurgical Science and Technology Progress Award in 2017 (provincial and ministerial level).

In 2015, the second prize of Anshan Science and Technology Progress Award.

In 2011, the second prize of Hebei Science and Technology Progress Award.

Has published a monograph "Properties of Coking Coal and Blast Furnace Coke Quality" and more than 10 papers.

Obtained 5 national invention patents and more than 10 utility model patents.

Independently presided over the completion of more than 20 national and enterprise horizontal scientific research projects.

The results obtained have been applied in a large number of domestic steel, coking, coal washing and other coal chemical enterprises. It has created huge economic benefits for related enterprises, and also brought huge social benefits. It has great influence and popularity in the field of coal chemical industry in China.

●Technical features of automatic intelligent coal coke petrographic analysis system

1. The overall technical conditions are strictly in line with the national standard GB/T 6948-2008 "Method of determining microscopically the reflectance of vitrinite in coal", GB/T 40485-2021 "Method of determining automatically the random reflectance of vitrinite in coal—Image analysis method" and MT/T 1053-2008 "Technical conditions of microscope photometer for vitrinite reflectance determination" and the international standard ISO 7404-5:1994,Methods for the petrographic analysis of bituminous coal and anthracite—Part 5:Method of determining microscopically the reflectance of  vitrinite,MOD.

2. Fast speed: 8 minutes/sample for single coal; 20 minutes/sample for mixed coal; 2 minutes/sample for coke porosity;

3. Accurate results: using Professor Zhao’s new third-generation intelligent identification technology of coal microcomponents, the identification accuracy of coal microcomponents is close to 100%;

4. Fully automated sample preparation: no manual experience required, 20 seconds/sample, 100% pass rate;

5. Really suitable for production: fully automatic sample preparation + scanning, can detect 60 samples per shift (8 hours);

6. It can be fully automated or manual (semi-automatic) detection to meet the application requirements of various occasions;

7. Coal can be analyzed: including: coal vitrinite random reflectance, vitrinite maximum reflectance, coal rock microcomponent quantification, coke pore structure parameter detection, coke optical structure detection, etc.;

8. More comprehensive coal quality assessment: One scan can simultaneously obtain vitrinite reflectance and coal rock microcomponent composition data, which is convenient for comprehensive coal quality assessment;

9. New high-precision (16-bit), 21 million pixels, 4/3-inch large target surface CMOS chip detector, ultra-stable, can be detected immediately after startup, without preheating, and can work continuously and stably for 24 hours; the pixel is smaller, and the detection of vitrinite is purer. Large target area, each scanning area covers a larger area, which can shorten the detection time;

10. The test process can be traced back: based on the intelligent identification of the format area information, it cooperates with high-precision detection to test the microscopic component content and vitrinite reflectance of coal. All images, test process, test results and original high-precision data are kept in the computer. Various test modes can mark the test results on the corresponding images, and the test process and test results of the tested samples can be repeatedly accessed for easy review. At the same time, it provides functions such as sample return and re-measurement, correction and re-statistical report in the virtual focus area.
