An attempt to produce blast furnace coke from Victorian brown coal

Influence Mechanism of Lignite and Lignite Semi-coke Addition on Drum Strength of Coke

“…[6][7][8][9] Nomura et al 10) investigated the effect of plastic addition on the coal caking property and found that the decomposition products of plastics would interacted with the coking coal during the carbonization process resulting in the decrease of coal caking property and coke strength. Mollah et al 11) had tried to produce blast furnace coke using lignite, its commercial products, and briquettes. However, it was found that the produced coke had high compressive strength but the reactivity was too high to be used in a blast furnace.…”

Significantly enhances caking index of long‐flame coal under tetralin‐glycerol/H2 system

“…Mechanical strength is the most desired property for coke. Compressive strength was used instead of drum strength in this study, that is, because it was impossible to obtain enough coke for drum index (DI) test . As shown in Table , the proximate analysis and compressive strength were tested to evaluate the properties of coke.…”

Numerical Investigation of Applying High-carbon Metallic Briquette in Blast Furnace Ironmaking

“…14,15) For each cell in the CZ, their reaction rates are expressed as Eqs. (3), (4). where, η is the fraction of liquid phase, k is the index of the cells surrounding the calculated cell; j (j = i) represents Fe, FeO and Gangue, and HCMB Fe for reactions 6, 7, 8, and 11, respectively; A k is the face area between cell k and the calculated cell, n  is the normal unit vector on the face of the calculated cell.…”

“…Because of the scarcity of the caking coal resources, the environmental pollution in the coke production, and the desire to reduce hot metal costs, tremendous efforts have been made on the low-coke operation technology in the developments of BF ironmaking sectors. 3,4) Many of the low-coke BF operation technologies concentrate on substituting the coke by non-caking coals or other reducing agents (e.g. oil, gas, and biomass).…”
