1 Scope
YS/T 1075 This section provides the vanadium aluminum, aluminum master alloy of molybdenum determination of carbon content.
This section applies to aluminum vanadium, molybdenum determination of carbon content of aluminum master alloy. Measurement range. 0.005% to 0.60%.
2 Method summary
High frequency induction heating furnace combustion, burning through the sample into the crucible by electromagnetic induction heating, the sample under high temperature conditions in carbon
And a small amount of CO2 released in the form of CO, CO2 and CO into the infrared detection cell for testing.
3 Reagents and materials
3.1 Carrier gas. oxygen (volume fraction of not less than 99.99%).
3.2 Power gas. nitrogen (0.28MPa) or oil-free compressed air.
3.3 iron flux. wC≤0.0005%.
3.4 tungsten tin flux. wC≤0.0008%.
3.5 porcelain crucible. 900 ℃ ~ 1100 ℃ after burning to 4h constant blank value removed in a desiccator.
3.6 standard sample.
4 Instrument
Carbon and sulfur analyzer (including the high-frequency furnace, vacuum devices, carrier gas purification system, analysis of the gas conversion system, infrared detection system).
5 Sample
The specimen shall crush a particle size less than 500μm. If oil test results will be high, we need to use an organic reagent (carbon tetrachloride, ether,
Acetone, etc.) to clean and pulverized detected.
Step 6 Analysis
6.1 Warm up
To fully preheated before instrumental analysis, so that the indicators of the instrument reaches the set value.
6.2 Instrument Leak
The use of the instrument or other auxiliary equipment leak detection program to determine the instrument without leakage phenomenon.
