Application of infrared carbon and sulfur analyzer in the determination of ultra-low carbon sulfur in alloy steel
The old customer of Nanjing Kirin Analytical Instrument-----Fuzhou Jinjiali Co., Ltd. mainly produces pipe joints, steel, alloy steel and other materials. Many years ago, it purchased Nanjing Qilin's arc infrared carbon and sulfur analyzer QL-HW2000E(C) type. This product adopts the infrared absorption method. According to the principle that CO2 and SO2 can selectively absorb infrared light, the energy received by the standard sample through the measuring cell detector is used as a reference, and the carbon in the sample is obtained after computer data processing. Sulfur content.
Carbon is an important element in steel. It is the main indicator that distinguishes iron and steel and determines the steel grade and grade. As C increases, the hardness and strength of steel increase, while the toughness and plasticity deteriorate, making the steel brittle and difficult to process; as the C decreases, the toughness of the steel is enhanced. The methods for measuring carbon include gas volume method, absorption weight method, conductance method, electricity method, non-aqueous titration method, photometric titration, and infrared absorption method. Sulfur is a harmful element in steel, which can cause hot brittleness of steel, reduce the mechanical properties of steel, reduce fatigue limit, plasticity and wear resistance, and affect the service life of steel. The method for measuring sulfur includes a titration method, a conductivity method, an infrared method, and the like.
Nanjing Qilin's arc-infrared carbon-sulfur analyzer mainly uses infrared absorption method to measure carbon or sulfur with low or high content. It has wide measuring range, strong anti-interference ability, complete functions and simple operation. The analysis results are fast and accurate, and in 2009, it was recognized as a famous brand product in Jiangsu Province.
