石墨漂浮;冷却速度;碳当量;石墨球大小
摘  要:
对石墨漂浮的形成机理进行了探讨 ,认为石墨漂浮就其本质来说是取决于石墨球的大小 ,漂浮的石墨只能是自由生长的石墨和共晶奥氏体圈形成前的共晶石墨。提供了石墨漂浮的临界尺寸概念 ,并指出在实际生产中控制碳当量和加快冷却速度是解决石墨漂浮最有效的办法。

摘  要:
Mechanism of causing graphite floating was studied,and considered that graphite floating depends ibyts nature on the size of graphite ball,and the floating graphite is only free growing one and Conception of critical size to graphite floating was presented and the most effective method to solve graphite floating was given of controlling carbon equivalent and quickly cooling.
