Impurity elements other than the matrix element iron in metal materials such as iron and steel 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 their varieties. The presence of impurity elements in steel has a great influence on the performance of steel.
Nickel can enhance the strength and toughness of steel. Chromium increases the hardness, heat resistance and corrosion resistance of steel. Tungsten, aluminum, vanadium, titanium and other elements can also improve the strength and heat resistance of steel. Carbon, silicon, manganese, sulfur, and phosphorus are the main impurity elements in pig iron and carbon steel, and are called the five major elements. Because they have a great influence on the performance of steel, general analysis requires testing these elements.
The HXE-4B carbon and sulfur analysis instrument can be used to detect carbon and sulfur elements. The sample is burned by an arc burner. The carbon volume method is used to measure carbon. The iodometric method is used to automatically titrate and measure sulfur. Imported precision micro pressure sensors and microcomputer programming automatic control work procedures, Detect the measurement results, make the carbon and sulfur element content digital direct reading, automatically print the measurement results; other elements are detected by HXS-3A microcomputer high-speed analyzer (multi-element analyzer), using advanced "intelligent dynamic follow" and "standard "Curve Nonlinear Regression" and other technologies, microcomputer control and data processing, can modify the curve, automatically display and print the test results, a total of 12 working curves can be stored, in theory, 12 elements can be detected. The detection accuracy and error are in line with national standards. The matching of the two instruments makes the economy fast and it is an ideal choice for casting iron and steel enterprises. It plays a decisive role in the production process.
A laser cutting machine is a laser device that forms a contour cutting gap on a cloth surface by a computer-controlled high-energy laser beam. The laser from the laser is focused into a high power density laser beam by a special optical path system. When the laser beam is irradiated onto the surface of the cloth, the contact point of the cloth instantaneously reaches the melting point and evaporates, and the laser head is controlled by the computer. When the relative position of the laser head and the cloth is moved, the cloth finally forms a contour cut for the purpose of cutting. The laser cutting machine has the characteristics of high precision, high speed, flexible cutting pattern setting, automatic typesetting, flat cutting and low processing cost.
Since the laser head does not contact the surface of the cloth, it will not cause scratches on the surface of the cloth; the cutting speed is fast, the slit is smooth and flat, generally no subsequent processing is required; the cutting has no mechanical stress, and there is no shearing burr; the processing precision is high and the repeatability is good. Does not damage the surface of the fabric. CNC programming can handle any complex floor plan and can cut coils of wide fabrics. It is the most popular process in the apparel printing industry.
