Introduction to the fully automatic inclusion analysis system

The OTS fully automatic non-metallic inclusion analysis system for steel is a comprehensive analysis system that integrates scanning electron microscopy, large-area high-speed energy spectrum detector, inclusion automatic analysis software, and sample cleanliness evaluation and recommendations. The system has a complete electronic optical imaging system, which can clearly observe the microstructure of non-metallic inclusions in steel. It is also equipped with an industry wide high-speed X-ray spectrometer, which automatically analyzes the chemical composition of all non-metallic inclusions in the selected area of the sample quickly and accurately. The analysis results can be visually displayed in seven categories of multicomponent phase diagrams including oxides, sulfides, nitrides, etc. The outstanding feature of the system is its ability to provide cleanliness evaluation of samples based on the composition, quantity, size, and distribution of inclusions, and to provide reasonable production recommendations based on the steel type and sampling station input by the user.

4. Able to accurately distinguish various phases in composite inclusions, and the analysis results can be visually displayed in seven categories of multicomponent phase diagrams including oxides, sulfides, nitrides, etc.

5. During the sample testing process, classify and statistically analyze all inclusions in the sample according to different refining processes (such as magnesium treatment, calcium treatment, rare earth treatment), or select different refining processes for reclassification and statistical analysis in the report. 、

6. Experts in the industry customize standard information and import it into the standard library. Users' standard libraries can also be combined in the periodic table. You can also manually edit the standard library. Detailed rating reports can be issued based on various inclusion rating standards and user needs, combined with automatic inclusion detection results, and reasonable production recommendations can be provided based on inclusion detection results.

Our advantages

Hardware configuration, stable analysis performance

The OTS fully automatic inclusion analysis system adopts a scanning electron microscope, which is an application-oriented scanning electron microscope that combines high performance, high resolution, and strong functionality. The system adopts a multi interface large sample and artistic grade objective lens design, providing high-resolution imaging function, which can quickly analyze various types of steel samples. And combined with X-ray analysis conditions, modern and accurate inclusion analysis has become a reality.

System wide automation

Manual analysis of various composite inclusions in steel is very time-consuming and requires users to have strong technical experience, which can easily lead to inconsistent results among different users. OTS solves this problem for users, achieving automated inclusion analysis with fast and accurate results.

Standard guarantee

The data obtained from the entire system can be classified according to various standards, and can be rated and a rating report can be issued. The importance of electron microscopy in large sample rooms: The size of the sample room determines your efficiency.

1. The large sample room can observe 9 samples at once or directly observe larger samples.

2. The large sample room allows for free and unrestricted movement of samples within the chamber, allowing for the observation of the full view of larger samples.

3. The large sample room can have more electron microscope interface positions, which can enhance the space for electron microscope upgrades.

4. The large sample room electron microscope needs to be equipped with a shock absorption system and a vacuum system to ensure sample observation in the large sample room.

The 5.5 axis motor table can achieve fully automatic multi angle control of the sample.
