Carbon and sulfur analyzer (infrared carbon and sulfur instrument)
Carbon and sulfur analyzer (infrared carbon and sulfur instrument)
Instrument principle The infrared carbon and sulfur analyzer refers to the use of high-temperature furnaces (mainly high-frequency furnaces, tube furnaces, and combustion furnaces) as the heating system. Under the conditions of oxygen-enriched and fluxing agents, the samples can be instantaneously and quickly fully burned. Which contains carbon and sulfur elements into carbon dioxide (CO2) and sulfur dioxide (SO2), and then use CO2 and SO2 to absorb specific wavelengths of infrared light, infrared energy through the gas before and after the change with the gas under test ... 详细Content>>
Instrument principle
Infrared carbon-sulfur analyzer refers to the use of high-temperature furnaces (mainly high-frequency furnaces, tube furnaces, and combustion furnaces) as the heating system. Under the conditions of oxygen-enriched and fluxing agents, the sample can be instantaneously and rapidly fully burned. The sample contains Of the carbon and sulfur elements into carbon dioxide (CO2) and sulfur dioxide (SO2), and then with the help of CO2 and SO2 absorption of specific wavelengths of infrared light, infrared energy through the test gas before and after the change in the relationship between the measured gas concentration and the line Lambert-Beer's law, the concentration of CO2 and SO2 signal into a voltage signal, and finally by means of software analysis, the content of CO2 and SO2, and the corresponding carbon and sulfur element content, the final analysis results to% C and %S is displayed in the form.
Instrument features and application areas
Infrared carbon-sulfur analyzer has the characteristics of adapting to many types of samples, fast detection speed, wide detection range, accuracy, precision, high sensitivity, and easy operation. In recent years, it has been widely used in metallurgy/metal, machinery manufacturing and processing, geology/mineral, coal/oil, cement/ceramic/glass and other industries.
Carbon and sulfur hazards
Carbon plays an important role in the performance of steel and iron analyzers: As the carbon content increases, the hardness and strength of the steel increase, and its toughness and ductility decreases. Conversely, as the carbon content decreases, the hardness and strength decrease, while the toughness and ductility increase. Carbon-sulfur analyzer is a commonly used measuring instrument in the physics and chemistry analysis room of an enterprise. It is used to quantitatively analyze the contents of carbon and sulfur in metal and non-metal materials, and is widely used in metallurgy, casting, machinery, vehicles, and valves. Ore, environmental protection, quality inspection and other industries and fields, can be quickly and easily carried out raw material acceptance, furnace analysis, product testing and other stages of analysis and testing.
Sulfur exists in steel and deteriorates the quality of steel, reducing its mechanical properties, corrosion resistance, and weldability. In particular, sulfur in steel, if it exists in the state of iron sulfide, due to its low melting point (about 1000 °C), will cause the phenomenon of "hot brittle" of the steel, that is, thermal deformation, cracking at high temperature work, affecting the product Quality and service life. Therefore, the lower the sulfur content in the steel, the better. In general requirements, the sulfur content in ordinary steel is less than 0.050%, the sulfur content in tool steel is less than 0.045%, and the sulfur content in high-quality steel is less than 0.020%.
