Today, I will take you to understand the characteristics of
inoculants with different ingredients
1. 75 Ferrosilicon: This is the most commonly used inoculant,
and the content of aluminum and calcium plays
an important role in the inoculation effect.
2. Strontium-containing ferrosilicon:
This kind of inoculant has a strong ability to eliminate white mouth,
which is especially beneficial to improve the shape and
distribution of graphite in thin-walled castings.
3. Barium-containing ferrosilicon:
This type of inoculant has a strong ability to promote graphitization,
which can improve the shape and
distribution of graphite in thin-walled castings,
and also slow down inoculation recession.
4. Zirconium-containing ferrosilicon:
This type of inoculant has a deoxidizing effect,
which is beneficial to improve the fluidity of molten iron,
reduce the tendency of white buckle of cast iron,
and promote uniform and fine A-type graphite.
It also has the effect of slowing down pregnancy decline.
5. Silicon-barium alloy:
The silicon-barium alloy containing 20-30% barium is used as an inoculant,
which can significantly reduce the white mouth tendency of cast iron,
and can increase the time of maintaining
the inoculation effect to about 30 minutes,
especially suitable for large castings.
During processing, the alloy addition amount is about 0.1%.
6. Silicon calcium alloy: Although it has a strong inoculant effect,
it is not suitable to use granular alloy as an inoculant for cast iron,
except for the application of cored wire.
7. Rare earth inoculant:
adding an appropriate amount has a strong inoculant effect,
and its effect is several times that of 75 ferrosilicon,
which can effectively eliminate white mouth
and slow down the decline of inoculum.
However, the dosage must be strictly controlled during use.
