Multi-element analyzer for chemical composition testing of steel
Multi-element analyzer is applied to the analysis of chemical composition of carbon structural steel. Carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel according to chemical composition (ie, carbon content). , S, Mn, P, Si, Cr, Ni, Mo, Re, Mg, Fe, Cu, Al, V, W, Ti and other common elements. Carbon and sulfur analysis uses infrared photometric analysis to significantly improve the accuracy of the analysis. The first wavelength-adjustable optical system for diffraction grating digital motors used in elemental analyzers in China. Program control and data processing are implemented using a computer. It can quickly and accurately measure the content of components in carbon steel, low carbon steel, medium carbon steel and high carbon steel. It has high automation and non-quantitative weighing function, accurate and reliable, and convenient for users to operate.
Material analysis of chemical composition of carbon structural steel:
Carbon steel can be classified into low carbon steel, medium carbon steel and high carbon steel according to chemical composition (ie, carbon content).
(1) Low carbon steel, also known as mild steel, contains from 0.10% to 0.30% carbon. Low carbon steel is easy to accept various processing such as forging, welding and cutting. It is commonly used in the manufacture of chains, rivets, bolts, shafts, etc.
(2) Carbon steel with a carbon content of 0.25% to 0.60% in medium carbon steel. There are a variety of products such as killed steel, semi-killed steel, boiling steel. In addition to carbon, it may contain a small amount of manganese (0.70% to 1.20%). Divided into ordinary carbon structural steel and high quality carbon structural steel according to product quality. Good thermal processing and cutting performance, poor welding performance. Strength and hardness are higher than low carbon steel, and plasticity and toughness are lower than low carbon steel. The hot rolled material and the cold drawn material may be directly used without heat treatment, and may be used after heat treatment. The medium carbon steel after quenching and tempering has good comprehensive mechanical properties. The highest hardness that can be achieved is about HRC 55 (HB538), and σb is 600 to 1100 MPa. Therefore, medium carbon steel is the most widely used in various applications at medium strength levels. In addition to being used as building materials, it is also used in the manufacture of various mechanical parts.
(3) High carbon steel is often called tool steel, with carbon content ranging from 0.60% to 1.70%, which can be hardened and tempered. Hammers, crowbars, etc. are made of steel with a carbon content of 0.75%; cutting tools such as drill bits, wire taps, reamers, etc. are made of steel with a carbon content of 0.90% to 1.00%.
