Foreword
This part is GB/T 4701.10-1988 "Methods for chemical analysis of ferrotitanium The infrared absorption method for the determination of sulfur content"
GB/T 4701.11-1988 "Methods for chemical analysis of ferrotitanium determination of sulfur content and combustion titration" integration amendment.
This Part replaces GB/T 4701.10-1988, GB/T 4701.11-1988.
This portion of the GB/T 4701.10-1988 and GB/T 4701.11-1988 comparison, the main changes are as follows.
--- Infrared absorption method Sample volume is adjusted by the 0.500g 0.25g;
--- Infrared absorption method flux increased from 0.50g tin particles, 1.50g to 0.25g tungsten particles tin particles, 1.0g tungsten particles, and add
Into 0.50g of pure iron;
--- Combustion and titration measurement range from the original ≤0.070% to 0.005% to 0.070%.

3 Method One. The infrared absorption method
3.1 Principle
The sample is heated in an induction furnace in an oxygen stream of combustion, the oxygen produced by the sulfur dioxide contained in the measuring chamber to the infrared analyzer dioxide
A sulfur absorbing specific wavelengths of infrared energy, which is proportional to the absorbed energy and the concentration of sulfur dioxide, according to the change in energy receiving detector may be measured
Sulfur content.

3.2.6 pure iron purity of more than 99.80%, a sulfur content of less than 0.0005%, particle size 0.8mm ~ 1.68mm.
3.2.7 oxygen purity of more than 99.95%, if other levels of oxygen to obtain a low and consistent blank value, may also be used.
3.2.8 power source gas, nitrogen or compressed air, which contaminants (oil and water) of less than 0.5%.
3.2.9 ceramic crucible diameter × height, 23mm × 23mm or 25mm × 25mm, and above 1200 ℃ high temperature furnace
4h or by burning oxygen burning to blank the lowest value.
3.2.10 crucible tongs.
3.3 Instrument
3.3.1 Sulphur infrared absorption analyzer (sensitivity of 1.0 × 10-6) which means shown in Figure 1.
