QUICK DECISION
Four answers before reading the technical detail
This section supports initial screening; final grade, addition and effects require operating conditions, formal documents and plant validation.
What it does
- Promote graphite nucleation
- Reduce undercooling and chill
- Stabilise microstructure
Where it fits
- Ladle or in-stream inoculation, as close to pouring as practical
- Post-inoculation after nodularising, in ladle or stream
- Controlled inoculation after CGI treatment
Boundary not to miss
- Early addition can suffer inoculation fade
- An unsuitable active-element system, size or dose can cause undissolved particles, inclusions or insufficient effect
- Excess or incompatible chemistry can increase slag, defects or structural variation
SELECTION BOUNDARY
Start with the selection boundary
First identify grey, ductile or CGI, then select active-element system and size from section thickness, cooling rate, base chemistry and addition equipment. Families include Ca-Ba, Sr, Zr, Sr-Zr, RE, Bi and Ca-Al; only company-approved actual offerings may become formal SKUs.
PRODUCT MANUFACTURING
Product manufacturing process
Silicon-based inoculants may be ordinary ferrosilicon intended for inoculation or FeSi-based compound systems with controlled Ca, Ba, Sr, Zr, RE or Bi. Formula and active-element control are generally supplier-specific.
- 01Inspect FeSi base and active-element feeds
- 02Controlled melting/formulation and homogenisation
- 03Cast, cool and crush
- 04Narrow sizing and fines removal
- 05Test active elements, size and lot
SPECIFICATIONS & PACKAGING
Grades, specifications, indicators and packaging
Create SKUs by active-element system, Si/Al/Ca indicators and ladle/stream sizing; a family framework is not a company stock grade.
- 01Confirm grey, ductile or validated CGI
- 02Select Ca/Ba/Sr/Zr/RE/Bi system
- 03Match size to ladle or stream inoculation
- 04Confirm actual company grade and pack

INDUSTRY APPLICATION
Industry, furnace, material and addition point
Confirm the process position before method and quantity calculations; an application relationship for one furnace or material must not be copied to another.
Iron foundries
Ladle or in-stream inoculation, as close to pouring as practical
- Furnace / equipment
- Liquid iron from cupola, induction or duplex melting
- Material / output
- Grey cast iron
Iron foundries
Post-inoculation after nodularising, in ladle or stream
- Furnace / equipment
- Nodularised iron from the applicable melting route
- Material / output
- Ductile cast iron
Iron foundries
Controlled inoculation after CGI treatment
- Furnace / equipment
- Validated CGI treatment route
- Material / output
- Compacted graphite iron (CGI)
APPLICATION METHOD
Application method and effect validation
Inoculation is generally close to pouring and selected against base iron, section thickness and fade time. Furnace FeSi adjustment and pre-pour inoculation are different product scenarios.
- 01Confirm iron type, base-iron S/O and thermal analysis
- 02Choose ladle/stream point and size
- 03Set treatment intensity from TDS and trials
- 04Verify chill, graphite form and fade
- 1Ladle inoculation
- 2Stream inoculation
- 3Fade timeline
- 4Microscopy/thermal analysis validation

PROBLEM AND SOLUTION
From operating objective to effect verification
Each application explains the role, method, quantity principle and risk boundary; the final proposal is confirmed against operating conditions and lot documents.
01
Iron foundries
Ladle or in-stream inoculation, as close to pouring as practical
- Furnace / equipment
- Liquid iron from cupola, induction or duplex melting
- Material / output
- Grey cast iron
- Method
- Similar names, forms or uses do not make products interchangeable; confirm product identity, specification, application process and order documents separately.
- Quantity determination
- Determine from carbon equivalent, S/O condition, base-iron nucleation, pouring temperature, fade time, section thickness, cooling rate and thermal-analysis/trial results.
Expected effects
- Increases nucleation and reduces chill/carbides
- Improves flake graphite and structural consistency
Limits and risks
- Early addition can suffer inoculation fade
- An unsuitable active-element system, size or dose can cause undissolved particles, inclusions or insufficient effect
02
Iron foundries
Post-inoculation after nodularising, in ladle or stream
- Furnace / equipment
- Nodularised iron from the applicable melting route
- Material / output
- Ductile cast iron
- Method
- Re-inoculate after nodularising and control the inoculation-to-pour time; nodularizer does not replace post-inoculant.
- Quantity determination
- Set from post-treatment iron condition, residual Mg, section thickness, target nodule count and fade time using thermal analysis, microscopy and trials.
Expected effects
- Raises nodule count and reduces chill/carbides
Limits and risks
- Excess or incompatible chemistry can increase slag, defects or structural variation
03
Iron foundries
Controlled inoculation after CGI treatment
- Furnace / equipment
- Validated CGI treatment route
- Material / output
- Compacted graphite iron (CGI)
- Method
- Validate as a system with the CGI treatment alloy, thermal analysis and residual-Mg control; do not directly transfer grey- or ductile iron practice.
- Quantity determination
- Determine from the narrow residual-Mg window, S/O condition, section thickness and CGI-rate feedback.
Expected effects
- Supports uniform compacted graphite and suppresses carbides
Limits and risks
- Incorrect inoculation intensity can alter graphite form and requires plant-specific validation
STORAGE & SAFETY
Storage, handling and risk
- Keep dry and minimise degradation; wet material and fines present splash, dust and reaction hazards in molten iron.
- Bi, Sb, B, RE and other active-element systems require review against final chemistry, microscopy and defect risk.
