随着海綿钛生产的扩大,其工艺和設备結构也在不断完善。工业上用鎂还原法生产海綿钛的还原反应器,上部結构不完善是其主要缺点之一。到目前为止,还原反应器是用垫有真空橡皮的平底盖子加以密封的。盖子下面装有隔热屏。此类結构的反应器,其上部溫度制度的特点是溫度梯度很大。隔热屏的下表面温度在850～900℃之間,而盖子的內表面溫度却只为150～250℃。
With the expansion of sponge titanium production, its technology and equipment structure is also constantly improving. Industrial production of magnesium reduction by the reduction of titanium sponge reactor, the superstructure is imperfect one of its main drawbacks. To date, the reduction reactor has been sealed with a flat bottom lid with a vacuum rubber pad. Under the cover with a heat shield. The reactor of this kind of structure, its upper temperature system is characterized by a large temperature gradient. The temperature of the lower surface of the heat shield is between 850 ° C and 900 ° C, while the temperature of the inner surface of the lid is only 150 ° C to 250 ° C.
