Impurity elements other than the matrix element iron in metal materials such as iron and steel include carbon, manganese, silicon, sulfur, and phosphorus. For ferroalloys or alloy steels, a certain amount of alloying elements, such as nickel, tungsten, molybdenum, vanadium, titanium, rare earth, etc., varies with their varieties. The presence of impurity elements in steel has a great influence on the performance of steel.
Nickel can enhance the strength and toughness of steel. Chromium increases the hardness, heat resistance and corrosion resistance of steel. Tungsten, aluminum, vanadium, titanium and other elements can also improve the strength and heat resistance of steel. Carbon, silicon, manganese, sulfur, and phosphorus are the main impurity elements in pig iron and carbon steel, and are called the five major elements. Because they have a great influence on the performance of steel, general analysis requires testing these elements.
The HXE-4B carbon and sulfur analysis instrument can be used to detect carbon and sulfur elements. The sample is burned by an arc burner. The carbon volume method is used to measure carbon. The iodometric method is used to automatically titrate and measure sulfur. Imported precision micro pressure sensors and microcomputer programming automatic control work procedures, Detect the measurement results, make the carbon and sulfur element content digital direct reading, automatically print the measurement results; other elements are detected by HXS-3A microcomputer high-speed analyzer (multi-element analyzer), using advanced "intelligent dynamic follow" and "standard "Curve Nonlinear Regression" and other technologies, microcomputer control and data processing, can modify the curve, automatically display and print the test results, a total of 12 working curves can be stored, in theory, 12 elements can be detected. The detection accuracy and error are in line with national standards. The matching of the two instruments makes the economy fast and it is an ideal choice for casting iron and steel enterprises. It plays a decisive role in the production process.
