唐钢连铸保护渣渣膜矿相分析

Analysis mineralogical phases of mold flux film from Tangsteel

采集河北联合钢铁集团唐钢中厚板有限公司1号连铸机保护渣渣膜,对应浇铸钢种为Q345B、Q235B。对渣膜进行宏观观察;采用X射线衍射手段,分析保护渣渣膜矿相成分;采用偏光显微镜,观测渣膜微观结构,分析渣膜微观矿相、玻璃相分层结构;分析保护渣原渣化学成分对渣膜矿相形成影响规律,为连铸结晶器保护渣研发及使用提供理论依据。

The mold flux film collected from Iron ＆ Steel Group for casting steel grades No. 1 CC machine of the Plate Mill of Hebei Q345B and Q235B is observed and then the constituents of mineralogical phases of the film are analyzed by X-ray diffraction and the microstructure of the slag film is observed by a polarizing microscope and micro mineralogical phase of the film and the stratification structure of the glass phase are analyzed and the effects of the chemical compositions of the mold flux on the formation of the mineralogical phase of the flux are checked and thus theoretical evidence is provided for development and application of the CC mold flux.
