Approximately 40% of the COG is used as a fuel in the coke oven.

1.1.1 Coke-making process Blast furnace coke is produced by heating coking coal to high temperature in the reducing atmosphere of the coke oven.[1] The coal-to-coke transformation is illustrated in Figure 1.[4] The coal mix is heated from the oven walls on each side of the coke oven and two plastic layers are developed on each side and converw a Coke Plant Works. Coal is the main ingredient used to make coke. Iron is produced by inputting coal into a blast furnace. However, coal cannot be put directly into a blast furnace because of all the harmful by-products that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first.

Coke is a processed form of coal, made in oven by driving off volatile elements. In blast furnaces, coke helps generate the 3000o F temperatures and reducing gases needs to smelt iron ore. About 1,000 pounds of coke are needed to process a ton of pig iron, an amount which represents more than 50% of an integrated steel mill's total energy use.Hot Rolling Mill and brief process of Hot Rolling Mill.

The use of a drum chute instead of the regular chute is proposed in coke sorting prior to classification. A method of calculating the optimal drum dimensions is outlined. The drum's inclination is plotted as a function of the required number of drum rotations to which the coke is subjected. A simplified method is considered for determining the number of drum rotations to which the coke must ...Answer (1 of 4): Coal is not directly used in blast furnace, coke is used directly. Part of coke is replaced with coal dust injection. It reduces the cost of hot metal as well as we can inject more oxygen to maintain the RAFT so the production is increased. Coal is grind and preheated for remo...

Coke products are generated in the process and are adapted to certain requirements depending on the intended use. These include water content, ash content, sulphur content, grain size, solidity and abrasion resistance. The most common end products today are blast furnace coke and foundry coke. The coal is delivered by train.A method of producing blast furnace coke from bituminous coals, particularly coals having poor coking capacities in which the coal to be carbonized is ground, predried or preheated, mixed with binders, compressed or formed into briquets having small mechanical resistances and charged into oven chambers, is characterized by fine coals or fine coal mixtures having a swelling index in mixture ...

In the event that the coke produced in drums 32 and 38 has sufficient strength and is suitable for use as bulk in the production of blast furnace grade coke, the coke may be separated into a portion of a size suitable for use as a blast furnace coke bulk, i.e. from about 3/4 inch to about 3 inches which is passed directly to calciner 124 and a ...The Role of Coke in Iron and Steel Production. While coke serves multiple purposes in a blast furnace, its most critical role is as a permeable support surface; coke acts as a support for iron-bearing burden, while allowing slag and metal to drain through to the hearth and gases to move upwards.².
