عنوان انگلیسی Effect of CaF2 on the contact angle of refining powder on NiCrMoV steel at high temperature using Image Analysis and Statistical Package for the Social Sciences software
چکیده انگلیسی مقاله Steel melting treatment powders always play an important role in reducing steel inclusions. These types of powders can be used in steel smelting production processes for all types of low-alloy and high-alloy steels. The composition of these powders are generally CaO-Al2O3-SiO2. Adding CaF2 values gives special properties to this type of refining powders. In this study, four types of refining powders with 3 to 6% of CaF2 were melted in induction furnace under high temperature and The surface of NiCrMoV low-alloy steel was impregnated by melting this sample of refining powders. The contact angle between the sample of melted refining powders and the surface of NiCrMoV steel was determined using Image Analysis (IA) and using Statistical Package for the Social Sciences (SPSS) was analyzed. The results showed increasing the percentage CaF2 about %6 in refining powder of CaO-Al2O3-SiO2 reduces the connecting angle of melting of refining powders on NiCrMoV steel about 60%.
