Effect of CaF۲ on the contact angle of refining powder on NiCrMoV steel at high temperature using Image Analysis and Statistical Package for the Social Sciences software

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-Al۲O۳-SiO۲. Adding CaF۲ values gives special properties to this type of refining powders. In this study, four types of refining powders with ۳ to ۶% of CaF۲ 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 CaF۲ about %۶ in refining powder of CaO-Al۲O۳-SiO۲ reduces the connecting angle of melting of refining powders on NiCrMoV steel about ۶۰%.
