全世界每年生产的粉末冶金制品价值约50—70亿美元,估计今后十年将以每年20—30％的速度增长。粉末冶金工艺最重要的问题之一,是金属粉末制品在热处理过程(预烧、烧结、预热等)中的能量消耗。不同阶段的热处理所消耗的能量约占整个粉末冶金过程总能量的60％以上。 The world’s annual production of powder metallurgy products worth about 5-7 billion US dollars, it is estimated that the next 10 years will be 20-30% annual growth rate. One of the most important problems with powder metallurgy is the energy consumption of the metal powder product in the heat treatment (calcination, sintering, preheating, etc.). The heat energy consumed in different stages accounts for more than 60% of the total energy of the whole powder metallurgy process.
