日本钛加工材的装运量1990年达历史最高记录,为8 964t,1991年下降18％,1992年又下降15％,为6 237t。其中出口加工材,在1990年为4 833t,占总量的54％,1992年急剧减少至约2 000t。这主要是由于向南朝鲜出口的冷凝管用窄带(总计700t)已到了设备投资的后期。另外,向英国出口也由原来的500t减至100t。日本国内的需求也从1990 Shipments of titanium materials for processing in Japan reached a record high of 8,964 tons in 1990, a decrease of 18% in 1991 and a further 15% in 1992 to 6,237 tons. Among them, the export processing materials amounted to 4,833 tons in 1990, accounting for 54% of the total. In 1992, the number dropped sharply to about 2,000 tons. This is mainly due to the narrow band (totaling 700 tons) of condenser tubes exported to south Korea which has reached the end of the equipment investment period. In addition, exports to the United Kingdom from the original 500t reduced to 100t. Demand in Japan is also from 1990
