low-caibon microallyed cast steelsis Àý¾äÈçÏ£º The modification effect of RE and Ca on nonmetallic inc lusions in carbon low-alloy and microallyed cast steelsis studied- By means of SEM7EMPA and quantitative metallogra-ph, the morphology and composition of nonmetalltc inclusions in the modified and unmodified steels are analyzed. The influence of the kind of modifiers and the method of modification on the morphology control of nonmetallic inclusions are discussed ̽ÌÖÁËÏ¡ÍÁºÍ¸Æ¶ÔÌ¼ËØÖý¸Ö¡¢µÍºÏ½ðÖý¸ÖºÍµÍ̼΢ºÏ½ðÖý¸ÖÖзǽðÊô¼ÐÔÓÎïµÄ±äÖÊ×÷Óá£ÓÃɨÃèµç¾µÐÎò¡¢µç×Ó̽Õë¶Ô¾±äÖÊ´¦ÀíºóµÄ¸ÖÖзǽðÊô¼ÐÔÓ½øÐÐÁËÎ¢Çø³É·Ö¼°¶¨Á¿½ðÏà·ÖÎö¡£»¹ÌÖÂÛÁ˱äÖʼÁºÍ±äÖÊ´¦Àí·½·¨¶Ô·Ç½ðÊô¼ÐÔÓÎïµÄÐÎ̬ӰÏìºÍ¿ØÖÆÐ§¹ûµÈ¡£ |
