摘要
对正火后分级机叶片底部出现的粒状珠光体组织与叶片中部出现的层片状珠光体组织进行比较,并对前者形成原因及其对耐磨性的影响进行了研究。结果表明:随正火温度提高,珠光体球化更完全,底部900℃正火试样获得完全球状珠光体组织;850℃正火试样具有最佳耐磨性。
The microstructure of granular pearlite was compared with lamellar pearlite on the middle. The formation reason of granular pearlite on the bottom of classifier blade and the effect of which on wear resistance were researched. The results show that pearlite spheroidization complied with normalized temperature increasing. At 900 ℃, normalized sample is spheroidized absolutely. The best wear resistance sample is achineved by normalized at 850 ℃.
