Description

[Detailed Description of the Invention] This invention relates to a steel spectroscopic analysis device.
This system handles the entire process unmanned, from receiving analysis samples to determining, reporting, and recording analysis results, and even when a failure occurs in a measuring device, it can respond quickly and support continuous operation. This realizes dynamic automation that is directly linked to the process.

Normally, spectrometers have major advantages over other analytical instruments in terms of speed and accuracy.
In combination with computers, it has evolved to the point where it is now an essential analytical instrument indispensable to steel manufacturing.

On the other hand, in order to cope with the increasing size and speed of the steel manufacturing process and the continuous use of continuous casting machines, further shortening the time required for analysis has become an issue.

In order to cope with this situation, this invention automatically and quickly transports the sample, cuts and polishes the sample, and prepares it for analysis. However, the purpose is to ensure that continuous operations are not disrupted.

An embodiment of the present invention will be described based on the drawings.

Continuous casting factory 2a, degassing factory 3a, converter factory 4a
A caseless pressure-feeding sample transport pneumatic pipe device 5 is provided between the sample collection site 1 and the sample analysis center 6, which transports the analysis sample (not shown).
The pneumatic tube device 5 is designed to be able to rapidly transport an analytical sample in a red-hot state between locations quite far away, from 600 m to 800 m, using a pneumatic tube.

At the sample analysis center 6, a receiver 7 receives the analysis sample, and a switch 8 sends the analysis sample to either the main measurement system 20 or the preliminary measurement system 30. In other words, normally, the analysis sample is automatically sent to the main measurement system 20 where the automated sequence is activated, but if a problem occurs in the analysis process and the automated sequence does not proceed, the switch 8 must be operated manually. The analysis sample is then sent to the preliminary measurement system 30.

The automatic cutting and polishing machines 21 and 31 cool and cut the received analytical sample in a red-hot state, and automatically polish the surface of the specimen so that it can be analyzed.

The transport robots 22 and 32 are automatic cutting and polishing machines 2.
The specimens finished in steps 1 and 31 are gripped and transported to intermediate trays 23 and 33. Analysis robot 2
Reference numerals 4 and 34 grip the specimen from the intermediate trays 23 and 33 and set it in the spectrometers 26 and 36, and grip the standard sample (not shown) from the standard sample polishers 25 and 35 and set it in the spectrometer 26 and 36, respectively. 36 and is also used for standardization work to correct changes over time during analysis to the initial state. Furthermore, analysis robot 24,3
4 can grip the standard sample again after the analysis and return it to the standard sample polishing machines 25, 35.

The photometric values obtained by the spectrometers 26, 36 are converted into contents by the microcomputers 27, 37, and transmitted to the analysis computer 10a. The analysis computer 10a stores information such as the serial number and manufacturing factory name of the analysis sample in advance on the respective setting panels 2b,
Since the information is received from 3b, etc. and stored, the analysis results can be automatically reported to the host computer 11 by comparing the information with the analysis values from the spectrometers 26 and 36. That is, the next sample cannot be started until the analysis computer 10a completes the report to the host computer 11.

In addition, before starting the analysis sample using the pneumatic pipe device 5, information on each analysis sample is sent to each setting panel 2b, 3 as described above.
The pneumatic tube device 5 will not operate unless it is transmitted from the data b and 4b to the analysis computer 10a.

If a trouble occurs in the analysis process in the main measurement system 20, the caseless pressure-feeding pneumatic tube device 5 for transporting the sample is temporarily closed, but if the switch 8 is operated to switch to manual mode, the analysis can be resumed. The sample is ready to be sent, and the analysis sample is sent to the preliminary measurement system 30 via the path 9, and the analysis process there is performed in the same way as in the main measurement system 20.

As described above, the present invention provides a caseless pressure-feeding sample transport tracheal device 5 for transporting analysis samples from a sample collection location 1 such as a continuous casting factory 2a or a degassing factory 3a to a sample analysis center 6. The analysis sample sent to 6 is normally sent to the main measurement system 20 via the switch 8, and when the switch 8 is manually switched, it is sent to the preliminary measurement system 30. The system 30 includes automatic cutting and polishing machines 21 and 31 that process the sample into a state that can be analyzed, and a transport robot 22 that transports the analysis sample processed by the automatic cutting and polishing machines 21 and 31 to intermediate trays 23 and 33.
32 and an analysis robot 2 that transports the analysis sample from the intermediate trays 23, 33 to the spectrometers 26, 36.
4, 34 and a microcomputer 27, 37 that converts the photometric values obtained by the spectrometer 26, 36 into content.
These and various computers 10a and 11 that measure, transmit, and record the data transmitted from the microcomputer of the main measurement system 20 or the preliminary measurement system 30 are arranged in series to analyze the sample. The system is configured so that all of the data can be processed automatically, and the caseless pressure-feed sample transport tracheal device 5 is temporarily closed when a failure occurs in the main measurement system 20.

According to the present invention, all the analysis work of the analysis sample is performed unmanned, and the analysis time is shortened, thereby realizing labor saving.

There are two systems, the main measurement system 20 and the preliminary measurement system 30, which include an automatic cutting and polishing machine that is particularly prone to wear.
It is a systematic system and can be switched manually, so it is possible to repair a malfunctioning part without disrupting continuous operation.

Furthermore, in order to realize unmanned analysis work, an automatic cleaning mechanism is attached to the light emitting electrode used in the spectrometer 26, thereby reducing the frequency of replacement.

Furthermore, in order to prevent deterioration of analysis accuracy due to changes in the spectrometer over time, correction work using standard samples can be made unmanned by combining the automatic standard sample polishing machine 25 and the analysis robot 24.

It also has the advantage of being able to easily configure the sample tracking system necessary for the entire process from shipping analysis samples to reporting analysis results.
