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
- Nodularising treatment
- Graphite morphology control
- Counteract sulfur and oxygen
Where it fits
- Treatment ladle after desulfurisation/preconditioning and before post-inoculation
Boundary not to miss
- Under-treatment causes poor nodularity; over-treatment can increase slag, fume and excessive residual Mg/RE
- The reaction is vigorous; moisture, fines, temperature and ladle condition affect safety and recovery
SELECTION BOUNDARY
Start with the selection boundary
Confirm base-iron S/O, treatment method, target residual Mg, section thickness and interfering elements before selecting Mg, RE, Ca, Al and size. More RE is not always better; clean feeds and heavy sections require review for chunky graphite. A nodulariser does not replace post-inoculant and is not recommended as a CGI treatment alloy; CGI requires a validated dedicated alloy and closed-loop control.
PRODUCT MANUFACTURING
Product manufacturing process
RE-Mg-FeSi is generally prepared by controlled Mg/RE alloying into an FeSi base, followed by casting, crushing and screening. Mg is highly reactive, so the manufacturing route and safety controls are strongly producer-specific.
- 01Inspect FeSi, Mg, RE and auxiliary feeds
- 02Controlled alloying and Mg recovery control
- 03Cast/cool and control homogeneity
- 04Crush, screen and control fines
- 05Test Mg/RE/Ca/Al and sizing
SPECIFICATIONS & PACKAGING
Grades, specifications, indicators and packaging
SKUs should distinguish Mg, RE, Si, Ca, Al and size. More RE is not inherently better; low/no-RE and medium/high-RE grades depend on base-iron purity, interfering elements and section size.
- 01Confirm Mg/RE grade framework
- 02Check Ca, Al and interfering elements
- 03Select sizing such as 3–15 or 5–25 for the treatment ladle
- 04Confirm moisture-protected pack and SDS/PSI

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
Treatment ladle after desulfurisation/preconditioning and before post-inoculation
- Furnace / equipment
- Induction and cupola–induction duplex routes; cupola iron requires particular sulfur review
- Material / output
- Ductile cast iron
APPLICATION METHOD
Application method and effect validation
Balance the treatment from base-iron S/O, temperature, ladle and target residual Mg, then close the loop with microscopy, residual Mg and trials. Post-treatment inoculation remains separate.
- 01Desulfurise if needed and remove slag
- 02Arrange nodulariser and cover for the treatment method
- 03Controlled sandwich/cover/cored-wire treatment
- 04Deslag, post-inoculate and verify residual Mg/microstructure
- 1Treatment-ladle layout
- 2Reaction/splash control
- 3Post-inoculation point
- 4Residual-Mg and microscopy verification

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
Treatment ladle after desulfurisation/preconditioning and before post-inoculation
- Furnace / equipment
- Induction and cupola–induction duplex routes; cupola iron requires particular sulfur review
- Material / output
- Ductile cast iron
- Method
- Use a validated sandwich, pocket or covered-ladle method; match sizing, ladle geometry, cover/conditioner and tapping stream, then deslag and post-inoculate.
- Quantity determination
- Balance from base-iron S/O, target residual Mg, product Mg/RE, treatment temperature, ladle and site Mg recovery, then correct with microscopy, residual Mg and trials; do not reuse a fixed legacy rate.
Expected effects
- The process objective is the target nodular state; final graphite form, residual Mg and mechanical properties require chemistry, microscopy and casting validation
Limits and risks
- Under-treatment causes poor nodularity; over-treatment can increase slag, fume and excessive residual Mg/RE
- The reaction is vigorous; moisture, fines, temperature and ladle condition affect safety and recovery
STORAGE & SAFETY
Storage, handling and risk
- Keep dry, minimise fines and follow molten-metal procedures; magnesium reaction can generate splash and MgO fume.
- SDS/PSI must reflect actual Mg, RE, form and destination regulations.
This section does not replace the company's final SDS/PSI or the plant safety procedure.
