The recovery rate and distribution of rare earth elements with the condition of feeding rare earth wire in liquid in stainless steel continuous casting mould are studied by industrial test and numerical simulation. The results show that feeding rare earth wire into the mould has 85% rare earth recovery rate

but the content of rare earth near the solidified shell is relatively high and the distribution of rare earth is inhomogeneous (RE 0. 059% 〜0. 073% )

which is due to the high concentration and inhomogeneous distribution of rare earth in mould liquid at early solidification period. Therefore

the influence of solidification transformation on the distribution of rare earth should be considered in the simulation or industrial production. In order to avoid the segregation of rare earth elements

the matching of rare earth wire diameter

wire feeding speed and continuous casting parameters should be paid attention to.
