The world's first neutron moisture meter that successfully realized the automatic control of the sintering material moisture-the DF-5744 belt neutron moisture online detector was formally put into the sintering process automatic control system at the Angang Bayuquan site on March 7, 2012. As of press time, the equipment was stable and the moisture control accuracy reached 0.1%. This means that this sintered material moisture detection and control instrument developed and produced by Dongfang M & C has achieved great technological breakthroughs in continuous operation time, stability and control accuracy in terms of better on-site adaptability, and has completely got rid of The manual intervention realizes the fully automatic control of the sintering process. This equipment uses the slowing effect of hydrogen on neutrons. By measuring the count rate of slow neutrons, it can instantly reflect the number of water molecules in the material, so as to reflect the moisture content of the material, and realize the moisture control process and the entire production process. Automatic control to ensure the normal combustion of the blast furnace. Prevent the entire sintering process from being adversely affected by insufficient or excessive moisture of the mixture, thereby improving product quality and yield, and reducing production energy consumption. At present, there are two ways to detect the moisture of sintered materials at home and abroad: infrared moisture detection and neutron moisture detection. The imported infrared moisture meter can realize the automatic batching of the sintering process. However, because the instrument is particularly sensitive to the color of the material, it will cause a huge deviation when the material type is changed. Therefore, when using infrared technology to detect the moisture of the material, the parameters of the instrument must be changed according to different materials, and it cannot be separated from manual intervention. It has been reported abroad that a neutron moisture meter is used to detect the moisture of the sintered material. However, most imported neutron moisture meters are used for moisture detection of blast furnace coke. For many domestic tenders for sintered belt moisture meters, the imported neutron moisture meter products have given up bidding opportunities. In view of the particularity and complexity of the sintering production process, Dongfang M & C creatively applied the neutron water measurement technology to the moisture detection and control of the belt sinter material with the deep understanding of different sites and more than ten years of technical accumulation, completely eliminating The disadvantage of infrared moisture meter to measure the moisture of sintered material must be manual intervention. The instrument has major breakthroughs in "detection sensitivity", "material state change compensation method" and "device structure". Solved the long-standing technical problems of the ironmaking process. "Sintering" is the key process that determines the success or failure of iron-making blast furnaces. The ore powder and coke are directly charged into the blast furnace, because there is no gap in the blast furnace and it cannot be burned. Only by adding water to the ore powder to form particles of an appropriate size and sintering into slag-like sintered material products, the normal combustion of the blast furnace can be ensured. The amount of water added to the sinter is the key parameter of the sintering process. If the amount of water added is too small, the mineral powder will still not form particles; if the amount of water added is too large, it will be sintered into large pieces and become waste products. A deviation of 1% in the amount of added water will obviously affect the combustion efficiency of the blast furnace, which will affect the economic benefits of the ironworks. The successful development of the sinter material moisture meter has ensured the fully automatic optimized operation of the sintering process, which will definitely bring huge economic benefits to China's iron and steel (metallurgy) enterprises. double chaise lounge,Chaise Lounges,leather lounge chaise Guangzhou LoPhiDa Co.Ltd , https://www.guangdongwidinlsa.com
