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
- Steel deoxidation
- Aluminium adjustment
- Support for inclusion-route control
Where it fits
- Added at tapping, during ladle refining or after vacuum treatment according to the deoxidation practice
Boundary not to miss
- Moisture, oil, rapid or excessive addition can cause splashing, Al oxidation loss, increased inclusions, nozzle clogging or Al exceedance
SELECTION BOUNDARY
Start with the selection boundary
Aluminium deoxidizer acts directly on steel and is not ladle-slag deoxidizer, aluminium cored wire or an Al–Si master alloy for aluminium casting; forms are not unconditionally interchangeable.
PRODUCT MANUFACTURING
Product manufacturing process
Aluminium deoxidizer for steelmaking may be made from verified metallic aluminium feed through actual routes such as remelting, cleaning, casting, cutting, granulation, shot making or briquetting into different supply forms. The supplier must declare feed identity, any binder/additive, contamination control and actual route; this general description does not represent Jinsheng-owned production.
- 01Verify metallic aluminium feed, provenance, surface cleanliness and residual elements
- 02Use remelting/cleaning, cutting, granulation, shot making or briquetting as applicable to the actual product
- 03Control oil, moisture, foreign matter, unit mass/sizing and lot mix-up
- 04Sample representatively and test Al, limiting residuals, form and packing safety
- 05Identify forms separately, pack dry and retain lot traceability
SPECIFICATIONS & PACKAGING
Grades, specifications, indicators and packaging
An aluminium-deoxidizer specification should identify the metallic aluminium feed, Al and limiting Fe/Si/Cu residuals, surface cleanliness, oil/moisture/foreign-matter control, and separately define unit mass/sizing, binder or additive, pack, sampling and COA for ingot, granule, shot, cut-piece or briquette forms. GB/T 1196—2023 is only a feed-product identity reference and does not replace a formal steelmaking TDS.
- 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
Added at tapping, during ladle refining or after vacuum treatment according to the deoxidation practice
- Furnace / equipment
- BOF/EAF tapping ladle, LF or post-RH ladle
- Material / output
- Steel grades using aluminium deoxidation or requiring Al trimming
APPLICATION METHOD
Use scenarios, method, effect and risk validation
Use for steel deoxidation/Al trimming in BOF/EAF tapping, LF or post-RH ladles. Calculate deoxidation Al demand and target net Al increase separately, then select form and sequence from endpoint O, lot Al, slag, inclusion route and site recovery. A matched practice can lower dissolved oxygen and establish target Al; moisture, oil, rapid or excess addition can splash, oxidize, increase inclusions, clog nozzles or exceed Al. Verify steel samples, oxygen and inclusions; it is not ladle-slag deoxidizer.
- 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
Added at tapping, during ladle refining or after vacuum treatment according to the deoxidation practice
- Furnace / equipment
- BOF/EAF tapping ladle, LF or post-RH ladle
- Material / output
- Steel grades using aluminium deoxidation or requiring Al trimming
- Method
- Choose form and sequence from endpoint oxygen, target acid-soluble/total Al, slag and inclusion route, ensuring immersion, melting and mixing.
- Quantity determination
- Calculate deoxidation Al demand and net Al increase separately, using measured lot Al and site recovery and checking Fe, Si, Cu and other residual carry-in.
Expected effects
- Can lower dissolved oxygen and establish target Al when sequence and slag condition are matched
Limits and risks
- Moisture, oil, rapid or excessive addition can cause splashing, Al oxidation loss, increased inclusions, nozzle clogging or Al exceedance
STORAGE & SAFETY
Storage, handling and risk
- Keep dry, oil-free and segregated by form; prevent wet material, sealed containers and rapid reaction from causing splashing in hot steel.
