High-frequency infrared carbon-sulfur analyzer for the detection of ductile iron materials Ductile iron has been widely used for various types of mechanical parts because of its high comprehensive mechanical performance, such as internal combustion engine crankshafts, camshafts, automobile clutches and chassis parts, certain machine tool spindles, ploughshares in agricultural machinery, and valve bodies in general machinery. , hydraulic components, etc. It is also widely used to produce cast pipes, rolls and ingot molds. The high-frequency infrared carbon-sulfur analyzer professionally produced by Nanjing Kirin Scientific Instrument Group can quickly and accurately detect the contents of carbon and sulfur in ductile iron materials. It is also widely used to detect ferroalloys, stainless steels, carbon steels, alloy steels, cast irons, and balls. The contents of carbon and sulfur in iron, non-ferrous metals, and other materials. High Frequency Infrared Carbon and Sulfur Analyzer - Dual CPU processing system; High precision acquisition system, up to four times per second; Industrial module power supply, strong anti-interference ability; Platinum infrared light source, sufficient energy of light; Adopting aviation motor modulation Light source signal, signal stability; gold-plated detection chamber, less light absorption; can increase dual-carbon infrared detection pool, automatic switching and so on. Nanjing Kirin Scientific Instrument High Frequency Infrared Carbon and Sulfur Analyzer Production Site The admixture used for the spheroidizing treatment is called a spheroidizing agent, and commonly used are pure metal magnesium and alloys. Compared with ordinary gray cast iron, ductile iron has higher strength, better plasticity and toughness. China is rich in rare earth metals, and ductile iron has become a widely used structural material. Production process: pure magnesium, nickel-magnesium, silicon-iron-magnesium or ferrosilicon-rare earth magnesium alloys are added as spheroidizing agents to molten iron with slightly higher carbon-silicon content and lower sulfur-phosphorus content, and then ferrosilicon, silicon-calcium or other multicomponents are used. The alloy is inoculated and nodular cast iron can be obtained in the cast state. In order to further change its mechanical properties, ductile iron can be subjected to various heat treatments such as annealing, normalizing, quenching, tempering or isothermal quenching. According to the chemical composition, solidification rate, and heat treatment specifications, the microstructure of spheroidal graphite cast iron is different from that of spheroidal graphite. Different metal substrates can be obtained. Ferrite ductile iron with low tensile strength and high elongation; pearlite ductile iron with high tensile strength and low elongation; and bainite and austenite both with excellent tensile strength and elongation. Body - bainite ductile iron and so on. Ductile iron Development: In order to reduce casting defects and improve the mechanical properties of ductile iron at the same time, people are studying to improve the molten iron smelting process, reduce the sulfur content of molten iron, develop new inoculants, and perform a variety of mechanical properties such as high and low temperature performance, fatigue Research work on strength, fracture toughness, and testing. It is also an important development direction to develop a production process that can make ductile cast iron reach the desired performance without heat treatment, and to add a small amount of alloying elements to obtain ductile iron with higher tensile strength and elongation.
