High-frequency infrared all-round element analyzer for steel materials The source of carbon in steel: One of the raw materials for ironmaking is iron ore, and the main component of iron ore is Fe2O3, without carbon. The second raw material for ironmaking is that part of the coke in the coking ironmaking process remains in the molten iron, resulting in carbon in the molten iron. Steel: Iron and steel is produced from iron ore. Raw iron is used as raw material for steel making. The process of steel making is mainly a process of removing carbon. Carbon cannot also be removed. Steel needs a certain amount of carbon to achieve its performance. Kirin Nanjing Science Instruments Group specializing in the production of high-frequency IR QL-HW2000BA versatile elemental analyzer can quickly and accurately detect an iron alloy, stainless steel, carbon steel, alloy steel, cast iron, ductile iron, nonferrous metals, rare earth metals, cement, minerals, The mass fraction of various elements in coke, iron ore, inorganic organics, non-ferrous metals, and other materials , this testing equipment has a quality control for steel companies and meets national standards . In 2009, it was identified as a famous brand product in Jiangsu Province Product patent number: ZL2004 2 0080129.X Science and Technology Achievement No.: 93A2005Y0015 According to chemical composition 1. Carbon steel Carbon steel refers to iron and carbon alloys containing a small amount of elements such as manganese, silicon, sulfur, and phosphorus in addition to iron and carbon. According to their carbon content, carbon steel can be divided into: (1) Low carbon steel - carbon content wc ≤ 0.25% (2) Medium carbon steel - carbon content wc> 0.25% to 0.60% (3) High-carbon steel - Carbon content wc> 0.60% High-carbon steel is generally more in military and industrial medical industries Second, the alloy steel In order to improve the performance of steel, in the smelting of carbon steel, adding some alloying elements and refining of steel, such as chromium steel, manganese steel, chromium manganese steel, chromium nickel steel. According to the total content of alloying elements, it can be divided into: (1) low-alloy steel - the total content of alloy elements ≤ 5% steel (2) Alloy steel - the total content of alloying elements 5% to 10% (3) High-alloy steel - the total content of alloy elements >10% Divided by smelting equipment (1) Converter steel Converter steel can be divided into bottom-blowing, side-blown, top-blown and air-blown, oxygen blowing and other converter steels; according to the different furnace linings, it is divided into two types, acidic and alkaline. (2) Open hearth steel The steel produced by open hearth refining is divided into two types, acidic and basic, depending on the material of the lining material. Generally, open hearth steel is mostly alkaline . Nanjing Kirin Scientific Instrument Group Co., Ltd. Testing Center 2016.03. 23
Masking Tape
Masking tape is mainly used in electronic, hardware, furniture, handicraft shoes, toys and other industries. Maskingtape is high temperature resistant (60-300 degrees). Masking tape has many colores, can stick to the paper, composite PET, PVC and other materials. Paper masking tape suitable for curved and contoured surface. The thickness of paper masking tape is from 45 to 65 micron, the width is from 12mm to 24mm, the length is 20 to 100 yards. Could make customs masking tape.
