The structure of liquid pure iron at 1550 ℃ was studied by θ-θ liquid metal X-ray diffractometer. The dynamic viscosity and surface tension of liquid pure iron were calculated by Iida and Reynolds formula The results show that the kinetic viscosity of liquid pure iron at 1550 ℃ is η = 6. 44mPa · s and the surface tension is γ = 2.04N / m. According to the formula γ / η = 1516 kT / m, The agreement between the viscosity and the surface tension is good; there is a close relationship between the liquid structure, the dynamic viscosity and the surface tension
