Abstract：
The dynamic melting behavior of nodularization core wire front end in molten iron was studied by manual insertion method.The correlation between molten iron temperature and feeding speed and the depth of fusion burst was explored.The results show that there is always a high concentration of magnesium evaporating zone in the front-end of cladding wire.When the temperature of molten iron is fixed,the depth of melting explosion increases nonlinearly with the increase of feeding speed.When the feeding speed is constant,the melting depth tends to decrease with the increase of molten iron temperature.On the basis of experimental research,the theoretical prediction model of molten iron temperature-feeding speed-melting depth is established.
