中文摘要: 对I型炉海绵钛生产过程中蒸馏设备特点和蒸馏操作工艺进行了介绍，分析了蒸馏通道堵塞原因并提出了相应的控制方法。蒸馏通道堵塞的主要原因是泵的有效抽速与镁和氯化镁挥发量不匹配、真空蒸馏系统气密性不良、蒸馏罐与冷凝器间温度梯度控制不合适。
Abstract:Characteristics of vacuum distillation equipment and operation processes were introduced when Ⅰ—type furnace was applied to produce titanium sponge. Causes of intermediate channels blockage were analyzed and corresponding controlling measurements were put forward. The main causes of intermediate channels blockage include mismatching between effective pumping speed and volatilization quantity of magnesium and magnesium chloride, poor tightness of vacuum separation system, and inappropriate temperature grade control between separation vessel and condenser.
