Determination of carbon content and sulfur content by metal element analyzer

The most important and most basic elements in steel are the five major elements of carbon, sulfur, silicon, manganese and phosphorus. The content of the five major elements directly affects the performance and grade of the steel. Among them, carbon and sulfur are important elements in determining the specifications and quality of steel products. It is also the most important measurement element of the metal element analyzer . Carbon with a carbon content higher than 1.7% is called cast iron , and steel with less than 1.7% is called high carbon steel. Carbon content is higher than 0.6% . The carbon content is 0.25%-0.60% called medium carbon steel , and less than 0.25% is called low. Carbon steel.

How to determine the carbon and sulfur content in steel ?

The sample is first passed through a high temperature furnace combustion oxygen is generated and escaping CO2 and SO2 gas, separation of carbon and sulfur with metallic elements and their compounds, the method for measuring the content of CO2 and SO2 are:

( 1 ) Volumetric method: The gas volume method and the non-aqueous titration method are commonly used , and the sulfur content is determined by an iodometric method and an acid-base titration method. Wherein the gas volume as measured carbon, iodine statutory sulfur, fast and accurate joint is the most common method of measuring carbon and sulfur. Precision stainless analyzer, a lower limit of 0.050% carbon content, sulfur content lower limit of 0.005%.

(2) IR method: Determination of carbon and sulfur by an infrared method, also accurate, fast, and high sensitivity, an infrared measuring instrument is used, a high degree of automation, the price is also high.

(3) determination of metal carbon, sulfur, there are the ICP method, X-ray fluorescence spectrometry, mass spectrometry, chromatography, and the like activation analysis, the sensitivity of some methods up to 10-10%. Analysis and development of high-speed and at the time of the relevant requirements and conditions.

In the steel-making furnace, we must race against time and demand high speed. The core metal element analyzer analysis of steel in the five elements, five elements focuses on the analysis of carbon and sulfur. Elemental analysis instruments and methods now, though involved in all areas, but instrument sales of carbon and sulfur analysis, turnover It accounts for more than 70% of high-speed analytical instruments .
