Hello everyone, I am the youngest girl in the factory.
Some netizens asked me privately,
how to solve the poor breeding effect of gray cast iron?
The basic solution is to use FeS-based S-increasing agent to
increase S to 0.07% to 0.10%.
A small number of factories also add O agents in the later stage,
such as sponge iron or sintered iron or chips,
so that [O] can reach more than 30ppm.
There are also factories that use oxygen-sulfur inoculants.
These methods are nothing more than generating oxysulfides,
which act as graphite cores.
