  The effects of wetting on the transfer of a particle into molten metal were investigated using three theoretical models. The effects of particle diameter and contact angle between the particle and molten metal on the force for particle transfer were also calculated. Using these theoretical models, for any arbitrary value of the three interfacial energies (solid/vapor, solid/liquid and liquid/vapor), contact angle, particle radius, ratio of dipped length, particle and liquid density, the actual force required for the particle transfer can be obtained. Furthermore, these equations were verified using water solutions and paraffin coated steel balls with a 1mm radius in experiments where the contact angle was varied from 0° to 105° by changing the concentration of the surfactant (sodium lauryl sulfate). The surface tension of these aquasolutions were measured by the maximum bubble pressure method.
