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
- Reactive CaO/MgO source
- Slag formation
- MgO-balance support
Where it fits
- Primary slag formation or a reviewed slag-adjustment point
Boundary not to miss
- Moisture hydration, over-burning or excessive storage can reduce reactivity and increase caking and dust
SELECTION BOUNDARY
Start with the selection boundary
Similar names, forms or uses do not make products interchangeable; confirm product identity, specification, application process and order documents separately.
PRODUCT MANUFACTURING
Product manufacturing process
Calcined-mineral products generally pass through quarry and chemistry review, crushing and screening, controlled calcination, cooling, finished sizing, reactivity/calcination-state and chemistry testing, and moisture-protected logistics. Kiln type, temperature schedule, fuel and specific controls belong to the actual manufacturer's documentation and are not assumed here.
- 01Confirm quarry source, mineral identity, feed chemistry and foreign-material control
- 02Crush and screen to the feed sizing required by the kiln
- 03Calcine and cool under the actual practice while managing underburning, overburning and degradation
- 04Test chemistry, loss on ignition, reactivity/calcination state, sizing and moisture
- 05Store sealed and dry, identify lots and control ageing from production to use
SPECIFICATIONS & PACKAGING
Grades, specifications, indicators and packaging
A light-burnt dolomite specification must state feed mineral, CaO/MgO and limiting constituents, loss on ignition, light-calcined/reactivity state, moisture, sizing, fines, degradation, storage life and pack. Natural-dolomite data cannot replace the calcined-product TDS; the page assumes no calcination temperature, reactivity value or shelf life, all of which require actual process and lot documents.
- 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
Primary slag formation or a reviewed slag-adjustment point
- Furnace / equipment
- BOF, EAF and reviewed ladle-slag systems
- Material / output
- Steelmaking slag systems requiring a more reactive CaO/MgO source
APPLICATION METHOD
Use scenarios, method, effect and risk validation
Light-burnt dolomite can provide a more reactive CaO/MgO source in reviewed BOF, EAF or ladle slag systems. Trial it against lot chemistry, reactivity/burn state, target MgO, lining and storage age. Qualified dry material can help establish an MgO-bearing slag faster; hydration, overburning or ageing can cause caking, degradation and lower reactivity. Do not replace natural dolomite or lime at a fixed ratio.
- 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
Primary slag formation or a reviewed slag-adjustment point
- Furnace / equipment
- BOF, EAF and reviewed ladle-slag systems
- Material / output
- Steelmaking slag systems requiring a more reactive CaO/MgO source
- Method
- Add according to calcination state, reactivity, target MgO and lining condition, controlling moisture and ageing from production to use.
- Quantity determination
- Calculate from lot CaO/MgO, target slag, other sources and site dissolution; do not apply a fixed replacement ratio for natural dolomite or lime.
Expected effects
- Can help establish an MgO-bearing slag more rapidly when reactivity and handling are controlled
Limits and risks
- Moisture hydration, over-burning or excessive storage can reduce reactivity and increase caking and dust
STORAGE & SAFETY
Storage, handling and risk
- Store sealed and dry, use first-in first-out and monitor hydration/caking; control alkaline and handling dust.
