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
- Meniscus coverage
- Shell lubrication
- Mould heat-transfer control
Where it fits
- Continuous mould-surface coverage after start stabilization through the casting sequence
Boundary not to miss
- Incorrect selection or cross-mixing can cause poor lubrication, abnormal heat transfer, accretion, entrainment and surface defects
SELECTION BOUNDARY
Start with the selection boundary
Mould flux is not tundish cover, starter flux, ladle cover or synthetic refining slag; their use points and physical-property targets differ.
PRODUCT MANUFACTURING
Product manufacturing process
Formulation and manufacturing route for casting powders depend on the specific product. A general route may include mineral, fluxing and carbonaceous feed review, metered blending and—according to the supplier route—raw-material, premelted/fused-and-crushed, spray-granulated or another verified process, followed by homogenization, screening, physical-property testing and moisture-protected packing. Different use locations must retain separate product identities.
- 01Verify mineral, fluxing and carbonaceous feeds and formulation identity
- 02Meter and blend to the approved formula and apply necessary premelting or fusion
- 03Crush and classify, spray-granulate or prepare the dedicated powder/granule form under the actual route
- 04Homogenize and sample, then test chemistry, melting, viscosity/rheology, crystallization or exothermic-related properties
- 05Segregate by use and grade, pack against moisture and retain lot traceability
SPECIFICATIONS & PACKAGING
Grades, specifications, indicators and packaging
Specification selection must confirm product identity, guaranteed chemistry, sizing, form, packing, test method and order use together.
- 01Confirm formal product identity, applicable standard, supplier grade and actual production route
- 02Fix principal chemistry, limiting items, physical indicators and the corresponding test methods
- 03Confirm form, size distribution, fines, moisture, flowability or unit mass for storage, handling and charging equipment
- 04Confirm pack, label, TDS, SDS/PSI, sampling rules and lot COA

ORDER SPECIFICATION CONFIRMATION
What must be confirmed before this becomes an order specification
Supply specifications, packaging, lead time and quality documents are subject to the formal quotation and order confirmation.
- 01Confirm the product, grade, application and supply scope
- 02Fix guaranteed chemistry, sizing, form and packing in the quotation and order
- 03Agree sampling, test methods, acceptance rules and lot COA fields
- 04Confirm the required TDS, SDS/PSI, labels and delivery documents

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.
Steelmaking plants
Continuous mould-surface coverage after start stabilization through the casting sequence
- Furnace / equipment
- Slab, bloom, billet, round or another continuous-casting mould
- Material / output
- Continuous-cast steel matched by grade and caster conditions
APPLICATION METHOD
Use scenarios, method, effect and risk validation
After casting start stabilizes, continuously cover the mould meniscus, maintain validated powder and liquid-slag layers, and replenish by consumption and meniscus condition. A matched grade can jointly support coverage, lubrication, heat transfer and inclusion absorption; wrong selection, moisture or cross-mixing can cause poor lubrication, abnormal heat transfer, entrainment and strand-surface defects. Verify by flux consumption, level, heat flux, breakout warning and strand quality; it cannot replace tundish/ladle cover.
- 01Confirm steel grade, process point, equipment, initial state, process objective and prohibited conditions
- 02Check the actual SKU, lot COA, TDS, SDS/PSI and site history
- 03Run a small site trial from mass/heat balances or the equipment window without copying a fixed cross-plant dose
- 04Resample or record slag, steel, temperature, equipment response, defects and performance before approval, correction or stop
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
Steelmaking plants
Continuous mould-surface coverage after start stabilization through the casting sequence
- Furnace / equipment
- Slab, bloom, billet, round or another continuous-casting mould
- Material / output
- Continuous-cast steel matched by grade and caster conditions
- Method
- Maintain validated powder and liquid-slag layers, replenish according to consumption and meniscus condition, and prevent foreign matter, wet material or incompatible grades.
- Quantity determination
- Establish a caster-specific window from section, casting speed, flux consumption, level fluctuation and strand-quality data; no fixed cross-caster dose is published.
Expected effects
- Can jointly improve coverage, lubrication and heat-transfer stability when grade and caster are matched
Limits and risks
- Incorrect selection or cross-mixing can cause poor lubrication, abnormal heat transfer, accretion, entrainment and surface defects
STORAGE & SAFETY
Storage, handling and risk
- Protect rigorously from moisture and segregate by grade; avoid dust, foreign matter and personnel exposure at the mould hazard zone.
