What it is
A dedicated slag-treatment family used to lower ladle top-slag oxidation, potentially aluminium-based or another verified system; its target is the slag, not a replacement for steel-bath deoxidation practice.

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
- Lowering top-slag oxidation
- Support for reducing steel reoxidation
- Ladle-slag condition adjustment
Where it fits
- Tapping slag adjustment or LF reducing-slag establishment
Boundary not to miss
- Excess, rapid reaction or incompatible formulation can cause slag deviation, splashing, inclusion changes or lining attack
SELECTION BOUNDARY
Start with the selection boundary
A ladle-slag deoxidizer targets top slag and is not equivalent to aluminium deoxidizer, ferrosilicon, silicomanganese or another alloy used directly to deoxidize steel.
PRODUCT MANUFACTURING
Product manufacturing process
This functional powder or granule family has no single production route representing every supplier. A general commercial workflow may include feed-identity and safety-document review, drying and classification, metered blending to a verified formula and—where applicable to the actual product—granulation, briquetting, premelting or another treatment, followed by screening, representative sampling, lot testing and moisture-protected packing. This general workflow is not presented as Jinsheng-owned production.
- 01Verify feed identity, source, formulation boundary and safety documents
- 02Dry, classify, meter and homogenize under the actual route
- 03Use granulation, briquetting, premelting or no-forming commercialization step as declared by the supplier
- 04Screen, sample representatively and test chemistry, physical properties, sizing and moisture
- 05Identify by lot and pack against moisture and mix-up
SPECIFICATIONS & PACKAGING
Grades, specifications, indicators and packaging
A ladle-slag deoxidizer specification must declare effective reductant constituents, carrier/slag-forming constituents, principal oxides, limiting residuals, moisture, sizing, melting and reaction behaviour, form, pack and lot testing, together with the applicable top-slag system. Aluminium-based material is only one possible route; an unverified formula cannot carry fixed indicators, and steel-bath deoxidizer specifications cannot be copied to slag deoxidizer.
- 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

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
Tapping slag adjustment or LF reducing-slag establishment
- Furnace / equipment
- BOF/EAF tapping ladle and LF
- Material / output
- Ladle-slag systems requiring lower oxidizing constituents such as FeO/MnO
APPLICATION METHOD
Use scenarios, method, effect and risk validation
Use in BOF/EAF tapping ladles or LF to lower top-slag oxidation. Add in batches from carryover-slag mass and initial FeO/MnO condition, target top slag, effective lot reductant constituents and stirring capacity. A matched system can lower reoxidation driving force; excess, rapid reaction or slag incompatibility can cause splash, inclusion changes and lining attack. Verify steel and slag separately; it cannot replace aluminium, silicomanganese or ferrosilicon deoxidation of the bath.
- 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
Tapping slag adjustment or LF reducing-slag establishment
- Furnace / equipment
- BOF/EAF tapping ladle and LF
- Material / output
- Ladle-slag systems requiring lower oxidizing constituents such as FeO/MnO
- Method
- After confirming carryover slag, steel deoxidation practice and target top slag, add in batches with adequate stirring and verify steel and slag samples separately.
- Quantity determination
- Calculate from top-slag mass, initial oxidizing constituents, effective lot reductant constituents and target slag condition, then correct from slag samples.
Expected effects
- Can lower ladle top-slag oxidation and reoxidation driving force when formulation and practice are matched
Limits and risks
- Excess, rapid reaction or incompatible formulation can cause slag deviation, splashing, inclusion changes or lining attack
STORAGE & SAFETY
Storage, handling and risk
- Manage moisture, dust and reactivity according to the reductant constituents; prevent splashing and maintain personnel exclusion during hot-ladle addition.
