In this video, let's talk about the "formation and impact of inclusions"
Inclusions mainly come from two aspects:
one is the impurities in the charge, its own impurities;
the other is the reaction product between the reaction product
of the smelting process and the surrounding medium.
Inclusions have the following effects on metal properties:
one. Inclusions destroy the continuity of the metal
and reduce the strength and plasticity;
two. Sharp-angled inclusions are easy to cause stress concentration
and significantly reduce impact toughness and fatigue strength;
three. Fusible inclusions are distributed in the grain boundary,
which not only reduces the strength
but also can cause thermal cracking;
4. Promote the formation of pores,
which can not only adsorb gas,
but also promote the nucleation of bubbles;
We Nanjing Difeng is committed to the production of
nodularizing agent, inoculant, vermicularizing agent,
covering agent, steelmaking deoxidizer,
alloy core wire and other products for cast iron,
with advanced technology, unique formula,
high efficiency, stability, good absorption and fusion, etc.
It can meet all kinds of enterprises that have
special requirements for precision machining and castings.
