摘　　要：分析了采用"I"型半联合法生产海绵钛的过程中,影响产品杂质含量和布氏硬度的因素,以及造成产品Cl、C、Fe、N、Mn等杂质元素含量偏高和硬度较高的原因,并提出严格控制原料纯度、新反应器使用前的清洁、生产过程中工艺控制、破碎加工过程减少有害杂质的污染等的具体措施,供海绵钛生产企业参考。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.
