Where Is The Impurity In The High Temperature Resistant Stainless Steel Sheet?

  Where is the impurity in the high temperature resistant Stainless Steel Sheet?

  Where is the impurity in the high temperature resistant Stainless Steel Sheet? On the high temperature of the Stainless Steel Sheet in the impurities from where the problem is a lot of people are very concerned about the production found in the formation of impurities mainly from a series of chemical reactions, how to send the reaction, the staff carried out Simple combing.

  In the production process of stainless steel, the deoxidizer (A1, FeSi, SiMn, etc.) added to the molten steel is oxidized to produce Al2O3, SiO2 and MnOAl2O3, SiO2-MnO, Al2O3-SiO2 (Cr, Ti, Si, Mn) are oxidized to form FeOCr2O3, SiO2-Cr2O3, Al2O3-Cr2O3, Cr2O3-MnS, TiO2 and other inclusions. During the cooling and solidification crystallization of molten steel, The temperature drop and localized segregation also form secondary deoxidation products. When these products are too late to discharge from the molten steel, it will remain in the steel to form endogenous inclusions.

  The inclusions in the finished stainless steel are in the process of smelting and casting, the erosion and erosion of the refractory material into the large inclusions of the molten steel, the slag mixed with the molten steel (such as the steel out of the AOD tapping process) Transport and casting process in the secondary oxidation and so on.

  Nitride in stainless steel is mainly in the form of TiN, which is dissolved in steel [N], and in the smelting, casting process, molten steel in the air N2 and steel [Ti] the role of the product. In addition, in the solidification process of molten steel, there will be CrN, Cr2N and other types of nitride generated.

  Above is the high temperature Stainless Steel Sheet may exist some impurities and sources, are basically the result of chemical reactions. On the one hand, enterprises should strictly screen high temperature stainless steel raw materials, on the other hand should also pay attention to 304 stainless steel angle in the production of chemical reactions to avoid the occurrence of finished products to ensure quality.
