Carbon* analyzer is widely used in metallurgical industry

Carbon and sulfur are important elements in determining the specifications and quality of steel products. Carbon with a content of more than 1.70% is called cast iron and less than 1.70% is called steel. Generally, the steel with carbon content higher than 0.60% is called high-carbon steel, the steel with carbon content between 0.25% and 0.60% is called medium carbon steel, the steel with carbon content less than 0.25% is called low-carbon steel, and the carbon content is less than 0.04%. Called industrial pure iron.

Carbon plays an important role in the performance of the steel analyzer: As the carbon content increases, the hardness and strength of the steel increase, and the toughness and plasticity decrease. On the contrary, when the carbon content decreases, the hardness and strength decrease, while the toughness and plasticity 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 areas, 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, work at high temperature cracks, affect the product's Quality and service life. Therefore, the lower the sulfur content in the steel, the better. In general, 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 measure the carbon and sulfur content in steel, that is, carbon and sulfur analyzers.
