Coke in the iron and steel industry ScienceDirect

2019-1-1  Metallurgical coke is produced in coke ovens and is mainly used for the iron ore reduction in blast furnaces (BFs). It is also consumed in blast and electric furnaces for ferroalloy production and for the reduction of other metal oxides, chlorides, phosphates, sulfates, as well as for the reduction of carbonates to carbides.

Metallurgical coke: formation, structure and

2021-5-19  Metallurgical coke consists of carbon grains of a variety of textures (i.e. isotropic, mosaic, fibrous, etc.) ash particles and pores. The most important mechanisms of coke degradation, as investigated in laboratories as well as by sampling at tuyeres, are: (1) cracking caused by preferential volume expansion of certain types of carbon grains, and (2) structural weakening caused by

Analysis of chemical-metallurgical agglomeration

Thermally activated chemical and metallurgical processes of lumping of fine-dispersed iron ore raw material during sintering are examined in the work. The following processes are included: moisture removal, ignition of coke fines and burn-off of carbonates, taking into account burning features of coke fines, fusion of grain charge, forming of agglomeration cake, creation of overhumidification

A Detailed Look at Iron Ore Agglomeration feeco

Pellets around 4-10 mesh provide a happy medium between iron ore fines (crushed/ground iron ore) and a chunk of iron (mined) for use in a blast furnace. Pelletization offers an effective solution to the items noted above. The ‘recipe’ for successful pelletization, however, is determined through testing. Iron Ore Agglomeration Tests

Environmental Assessment of Iron Ore Agglomeration

A study was carried out to compare the environmental impacts of the two major iron ore agglomeration processes, sintering and pelletising, using life cycle assessment (LCA) methodology. The following agglomeration processing routes, with the fuel options shown, were investigated: sintering with combined natural gas/coke breeze or charcoal as fuel, grate-kiln pelletising with combined natural
