Tungsten Granule Dosage
Tungsten granule is oxidized under oxygen atmosphere at 650℃ and releasing 195.85 Kcal /mol. Therefore, the sample will be heated to high temperature quickly and oxidized to CO2 and SO2.
The testing result is changed with tungsten granule dosage, following is a table to show the different testing result by using 0.5kg sample and 0.5g, 1.5g, 2.0g, and 2.5g flux.

Note:
A: Carbon steel
B: Pig iron
C: High carbon ferrochrome
1: Standard value (%)
2: Test value (n=5) (%)
3: Differnece (%)
Therefore, the quantity selection is an important process for testing C and S value.
