[程甫埭问]我在1955年第8期上看到“从元素周期表是否可以推断各种元素对於石墨化的影响”的问题讨论后,不了解「阻碍石墨化的元素钼、钼、钨在一族」与「在铸铁中加铝或矽不能细化石墨,将使石墨变粗」的说法是否互相矛盾。铝究竟是阻碍石墨化呢?还是帮助石墨化?根据某厂制造冷铸车轮用铝来控制白口深度的经验,每包铁水加 [Cheng Fu asked] I see in the first eight in 1955, “From the periodic table whether the various elements can infer the impact of various elements of graphitization,” the discussion, do not understand the “obstruction of graphitized elements of molybdenum, molybdenum , Tungsten in a group ”and“ adding aluminum in cast iron or silicon can not refine graphite, will make graphite thick ”argument is contradictory. Aluminum is hindered graphitization? Or help graphitization? According to a factory manufacturing cold-formed wheels with white aluminum to control the depth of experience, each pack of hot metal
