对于低硫铁水来说,加入相当于0.1%硅增量的含饰硅铁,会得到全部白口的铸件。这时相应的钵的增量为0.025%,这种孕育剂的碳化物促进作用,亦许是由于过量的钵而致。向含硫量十分低的铁水中加入相当于。
For low-sulfur hot metal, the addition of silicon-containing ferrites in increments of 0.1% will result in all white castings. At this time, the corresponding increment of the bowl is 0.025%. The carbide promoting effect of this inoculant may be due to the excessive bowl. To the sulfur content is very low added to the equivalent of molten iron.
