Do you know how to measure hydrogen by liquid aluminum?

1. The importance of hydrogen measurement in aluminum industry.

   The control of hydrogen solubility in liquid aluminum alloy is the key requirement of aluminum products industry. Aluminum producers and foundries around the world have invested heavily in fixed equipment, consumables and human resources to ensure that the dissolved hydrogen content is within acceptable limits. If the hydrogen content is too high, it is possible to form holes during curing. On the contrary, in some conditions, in order to overcome the shrinkage porosity, a moderate hydrogen content may be required. Therefore, the optimum hydrogen content should be established and controlled during casting. Although dissolved hydrogen is the key factor, the formation of pores is also affected by several other factors, the most significant of which is the cleanliness of molten metal, that is, the content of inclusions such as metal oxides. Hydrogen measurement techniques such as "decompression test" provide an indication of the combined effect of hydrogen content and metal cleanliness. However, in order to specifically analyze the hydrogen content, it is necessary to directly measure it. In addition, in order to control the hydrogen content, real-time and accurate measurement is required.

2. Our hydrogen meter

① Excellent characteristics of hydrogen meter:

  • Remote control Ethernet port can realize remote control.
  • Fast and efficient initial temperature reading < 5 minutes (typical), followed by response time < 5.
  • Traceability continuous measurement, data real-time continuous storage
  • Convenient on-site calibration service is provided for calibration.
  • Affordable can measure the cumulative usage of 100 times or 20 hours.
  • Plug and play without assembly.
  • Easy to use, same as standard thermocouple.

② absolute advantages of products

The British Hycal hydrogen meter represented by Matt New has the following advantages:

1) the weight is only 9.2kg, and the portability is good;

2) Wide application range: self-contained thermocouple, the probe length can be increased to 2m or more according to customer requirements, which can be used in pressurized furnace and degassing process;

3) It is powered by the battery, which gets rid of the range limitation and the risk that the wire is burnt out by molten aluminum, and can be brought to any occasion;

4) The measurement time is greatly shortened: the reaction can be carried out in 2s, and the measurement result can be obtained within 5min;

5) High accuracy: measurement error < 0.01ml/100g;

6) Low measurement cost: the cost of each measurement is 2~5 USD, which is one third of that of the common hydrogen meter;

7) Remote control: The MODBUS TCP technology can remotely control the probe, and the probe can be remotely controlled from the host to enter the aluminum melt, thus greatly increasing the safety;

8) Calibratable: the accuracy of the probe can be tested by using calibration gas (such as argon/nitrogen) in the system measurement process;

9) There is supporting special hydrogen measurement software, which is explained in multiple languages, and the operation is simple, and the results can be stored, uploaded and downloaded;

10) It has the function of automatic system diagnosis, and the operator will be automatically prompted if something goes wrong.
