What is the role of carbon and sulfur analyzer

The role of the carbon and sulfur analyzer is to determine the carbon and sulfur elements in various materials.  That is, the mass fraction of carbon and sulfur in steel, iron, alloys, non-ferrous metals, cement, ore, catalysts and other materials can be determined quickly and accurately.  Carbon and sulfur are important elements in determining the specifications and quality of steel products.  A carbon content above 1.70% is called cast iron, and a carbon content below 1.70% is called steel.  Generally, steels with a carbon content higher than 0.60% are called high carbon steels, steels with a carbon content between 0.25% and 0.60% are called medium carbon steels, and steels with a carbon content of less than 0.25% are called low carbon steels.  Called industrial pure iron.  Carbon plays an important role in the performance of iron and steel analyzers: as the carbon content increases, the hardness and strength of the steel increases, and its toughness and plasticity decrease; conversely, when the carbon content decreases, the hardness and strength decrease, and the toughness and plasticity  increase.  Carbon and sulfur analyzer is a commonly used measuring instrument in the physical and chemical analysis room of enterprises. It is used to quantitatively analyze the content of carbon and sulfur elements in metal and non-metal materials. It is widely used in metallurgy, foundry, machinery, vehicles, pumps, valves,  Industries and fields such as ore, environmental protection, and quality inspection can easily and quickly perform analysis and testing at the stages of raw material acceptance, pre-furnace analysis, and finished product inspection.  Sulfur is present in steel, which will deteriorate the quality of steel, reduce its mechanical properties, corrosion resistance, and weldability.  Especially the sulfur in steel, if it exists in the state of iron sulfide, due to its low melting point (about 1000 ° C), it will cause the "hot brittleness" of the steel, that is, thermal deformation, cracks at high temperatures and affect the product.  Quality and service life.  Therefore, the lower the sulfur content in steel, the better.  Generally, 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%.  In view of the important role of carbon and sulfur content in the quality and performance of steel, it is of great significance to detect the carbon and sulfur content in steel, that is, carbon and sulfur analysis.  The carbon and sulfur elements in the iron and steel stainless steel analyzer are combusted with oxygen at high temperature (1200 ℃ ~ 1400 ℃).  Both can be converted into gas to form CO2 and SO2. This is the basis of analyzing carbon and sulfur by combustion method.  The principle of carbon and sulfur analyzer analysis is that the sample is burned with oxygen in a high temperature furnace (such as a resistance furnace, also known as a tube furnace, an electric arc furnace, a high frequency induction combustion furnace, etc.) to generate and escape CO2 and SO2 gases.  Use this method to separate carbon and sulfur elements from metal elements and their compounds, then measure the content of CO2 and SO2, and then convert the carbon and sulfur content in the sample
