Mill scale - Part 2: Determination of sulfur content - High frequency combustion infrared absorption method

1 Scope

This Part of SN/T 3323 specifies high frequency combustion infrared absorption method, the method to determine the sulfur content in mill scale. This Part is applicable to the determination of sulfur content in mill scale. The determination range is 0.002%~0.40%.

2 Normative references

The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 2007.1, General rules for the sampling and sample preparation of minerals in bulk - Sampling by manual method GB/T 2007.2, General rules for the sampling and sample preparation of minerals in bulk - Sample preparation by manual method

3 Method summary

The test material is heated and burned in the oxygen flow of the high-frequency induction furnace. The generated sulfur dioxide is carried by oxygen to the measuring chamber of the infrared analyzer. Detect the infrared absorption energy of sulfur dioxide for specific wavelengths. Its absorption energy is proportional to its concentration. The sulfur content can be measured according to the change in the energy received by the detector.

4 Reagents

Unless otherwise stated, all reagents are analytically pure. 4.1 Pure iron flux: The particle size is less than 1.25mm. The carbon content is less than 0.0005%. The sulfur content is less than 0.0005%. 4.2 Tungsten-tin mixed flux: The ratio is 9:1, the carbon content is less than 0.0010%. ......
