| Abstract: | The factors that affect impurity content and Brinell hardness in the process of sponge titanium production u- sing of “I”-type semi-combined furnace were analyzed. According to the high level of C1, C, Fe, N, Mn content, several measures including strictly controlling the raw material purity, new reactor cleaning before using, process con- trol, and reducing harmful impurity pollution in the crushing process were presented, in order to provide the basis for the production of high quality sponge titanium. |
