Carbon and sulfur analyzer is the steel carbon and sulfur elemental analysis of the role of
The principle of carbon and sulfur analyzer analyzes, that is, the sample (e.g., also called resistance furnace tube furnace, arc furnace, high frequency induction furnace, etc.) through oxygen combustion in a high temperature furnace, and the generated escape of CO2 and SO2 gas, Using this method to achieve the separation of carbon and sulfur elements and metal elements and their compounds, and then determine the content of CO2 and SO2, and then convert the carbon and sulfur content of the sample.
Carbon steel, sulfur is an important element determining the size and quality of steel products, a carbon content higher than 1.70% or more is called cast iron, less than 1.70%, the steel is called. 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. Nanjing Kirin brand carbon and sulfur analyzer accurately detect an iron alloy, stainless steel, carbon steel, alloy steel, cast iron, ductile iron, nonferrous metals, rare earth metals, cement, ore, coke, iron, nonferrous metals and other materials in the plurality of elements Quality score .
Infrared carbon and sulfur analysis instrument
The general measurement methods are the following:
Infrared spectrophotometry: The carbon and sulfur in the sample are heated at high temperatures under oxygen-rich conditions and oxidized to carbon dioxide and sulfur dioxide gas. After the gas is processed into the corresponding absorption tank, the corresponding infrared radiation is absorbed, and the signal is relayed by the detector, and the output is processed by a computer. This method has the characteristics of accurate, rapid, high sensitivity, high and low carbon and sulfur content are used, using this method of infrared carbon and sulfur analyzer, a higher degree of automation, the price is relatively high, suitable for applications with high analytical accuracy requirements.
Arc Furnace Carbon and Sulfur Analyzer
Volumetric method: Commonly used carbon measurement methods are gas volumetric method and non-aqueous titration method. Sulfur measurement is iodometric method and acid-base titration method. In particular, the gas volumetric method to measure carbon and iodine content is the most rapid and accurate method for carbon and sulfur determination in China. The accuracy of carbon and sulfur analyzers using this method has a lower limit of carbon content of 0.050% and sulfur content. The lower limit is 0.005%, which can meet the needs of most occasions.
Tube furnace carbon sulfur analyzer
At present, there are a large number of carbon-sulfur analyzers in use in the following categories: infrared carbon-sulfur analyzers, tube furnace carbon-sulfur analyzers, electric-arc furnace carbon-sulfur analyzers, and non-aqueous carbon-sulfur analyzers. Users can use their own needs and The advantages and disadvantages of a carbon-sulfur analyzer are selected.
