We specify coke by chemistry, size, strength and reactivity criteria appropriate to blast furnace or foundry use.
Material characterization and acceptance
We define metallurgical coke by size fraction, moisture, ash, sulphur and fixed carbon, with strength and reactivity measures appropriate to the end use. CSR, CRI and drum-strength indices describe different test outcomes and require specified methods. Blast furnace, foundry and nut coke are not interchangeable grades.
Process compatibility and end-use requirements
Blast furnace ironmaking
We review CSR, CRI, size stability and chemistry in relation to burden permeability, mechanical support and reducing-agent requirements; test limits are agreed individually.
Foundry melting
We assess lump size, strength, ash and sulphur against cupola geometry, melt chemistry and thermal demand; foundry acceptance is distinct from blast furnace criteria.
Other metallurgical processes
We define reductant or fuel requirements by process chemistry, size distribution and impurity limits; breeze and nut fractions require separate handling and acceptance provisions.
