What are the functions of carbon and sulfur analyzers and elemental analyzers?

Metal materials such as steel can enhance the strength and toughness of steel. Chromium increases the hardness, heat resistance and corrosion resistance of steel. Elements such as tungsten, aluminum, vanadium, and titanium can also increase the strength and heat resistance of steel. Improved. Carbon, silicon, manganese, sulfur, and phosphorus are the main impurity elements in pig iron and carbon steel, and are called five major elements. Because they have a large effect on the performance of steel, these elements are generally analyzed in assays.

The carbon and sulfur analysis instrument can detect the two elements of carbon and sulfur. The sample is burned by an arc furnace, the carbon is measured by gas volume method, and the sulfur is automatically titrated by imported iodometric method. Carbon and sulphur content is displayed directly by digital display, and the measurement results are automatically printed; other elements are detected by a microcomputer high-speed analyzer (multi-element analyzer), and advanced technologies such as "intelligent dynamic follow" and "standard curve nonlinear regression" are used. And data processing, curve correction, automatic display and printing of test results, a total of 12 working curves can be stored, theoretically can detect 12 elements. The detection accuracy and error are in accordance with national standards. The two instruments are matched to make the economy fast, which is an ideal choice for foundry steel companies and plays a decisive role in the production process.

The impurity elements other than elemental iron 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 its variety. The presence of impurity elements in steel has a great influence on the properties of steel. Learn more about the product characteristics and price of carbon and sulfur analyzer, infrared carbon and sulfur analyzer , metal element analyzer.

When the carbon and sulfur analyzer is performing sample analysis, the arc furnace plays a certain role. The use of the arc furnace not only relieves the high-speed combustion of the sample, improves the working conditions, but also has a significant power saving effect. Using GQ-DRL type electric arc furnace, only one sample consumes 0.0003 kWh for combustion analysis. Compared with the horizontal tube furnace, one year of continuous use, an electric arc furnace can save 10,000 kilowatt hours.

Arc furnace combustion, acid-base titration, boiling titration continuous determination method. The main method is as follows: the sample is burned in the electric arc furnace by the "pre-large oxygen, after-controlled gas" process. The generated mixed gas containing sulfur dioxide and carbon dioxide is sequentially introduced into the fixed sulfur and fixed carbon absorption cups, and acts on the absorption liquid. In the fixed sulfur absorption cup, an aqueous hydrogen peroxide solution containing a mixed indicator of methyl red and bromocresol green is preset. After the introduction of sulfur dioxide gas, the generated sulfuric acid was titrated with a sodium hydroxide standard solution to determine the sulfur content. In the fixed carbon absorption cup, an ethanol-ethanolamine-potassium hydroxide solution containing a thymolphthalein indicator is preset. After the carbon dioxide gas is introduced, the carbon content is calculated based on the consumption of the alkaline non-aqueous solution.
