【摘要】 与单炉还原法比较,双炉还原法通过对工艺、设备及控制手段的改进,将四氯化锆与镁分别装入各自的反应炉中,使四氯化锆挥发、镁的熔融及还原反应分别进行,满足还原条件后,打通两个反应炉之间联接电热通道,进行还原反应生成海绵锆。此法反应区域、反应速度、反应温度、反应平衡容易控制,不仅提高了海绵锆的产量和质量,而且金属回收率高,废气排放少。更多还原

【Abstract】 compared with single furnace reduction method, double furnace reduction method based on the improvement of technology, equipment and control means, zirconium tetrachloride and magnesium in their respective reactor respectively, make zirconium tetrachloride volatilization, mg melting and reduction reaction, respectively, after reduction conditions, through the connection between the two reactor electric channel, to generate sponge zirconium reduction reaction. This law area, reaction speed, reaction temperature, reaction balance easier to control, not only can improve the yield and quality of zirconium sponge, and metal recovery rate is high, fewer emissions.更多还原
