In Figs. 1 and 2, we present the fracture microstructure of blast-furnace coke produced from KZh (51%) and K (49%) coking coal in the blast-furnace shop at AO ArcelorMittal Temirtau.On heating in the absence of air, the coking coal is converted to a plastic liquid state. The plastic mass surrounds solid grains of noncoking coal.

Coke: Coke is the primary fuel and reducing agents in the BF process. Depending on auxiliary reducing agents used, the coke consumption level is around 350–400 kg/t hm in modern blast furnaces. The metallurgical coke in the blast furnace acts as a reducing agent, energy carrier, and support medium for the burden material.

How 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 Fuel Low Sulphur Blast Furnace Coke / Metallurgical Coke / Pet Coke. Coke are made from a mixing material of serval kinds of coal,under a high temperature(1300ºC) process.They are widely used for steelmaking,ferroalloys manufacture or non-ferrous metals smelting,iron castings manufacture or other related metallurgical and foundry industry ...

Coke is used as fuel in a blast furnace. It plays an important role in the chemical processes that take place in a blast furnace. Coal is heated to about 1250 degrees Celsius in the coke ovens. This process is referred to as 'dry distillation' because these coke ovens are oxygen free, so the coal does not actually burn.

the coke breeze replacement is assumed to release the same mass of carbon. Carbon in blast furnace secondary fuel – At the blast furnace, all carbon from secondary fuels is released in addition to carbon from coke. The carbon is converted in the blast furnace into CO and CO 2 contained in the blast furnace gas (BFG), a by-product fuel leaving the

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. Changing production conditions to meet ...

Pulverized coal injection (PCI) is a process which involves injecting large volumes of fine coal particles into the raceway of the blast furnace (BF). Pulverized coal is an important auxiliary fuel used in the BF ironmaking. PCI provides auxiliary fuel for partial coke replacement and has proven both economically and environmentally favourable.

The major product is the blast furnace coke which is used in pig iron and steel manufacturing units. Depending on the customer requirement, the Blast Furnace Coke size can be customized. Other products for sale are Coke fines (< - 10 mm), Nut coke ( + 8 to …

Coke is an important raw material in the smelting process of the blast furnace, accounting for about 45%. Others include pellets, sinter, lump ore, limestone and so on. Regarding coke, some people may have doubts. Coke and coal are all high-heating fuels. Even some anthracites have higher calorific value than coke and are cheaper than coke.

Coke Gas. Coke gas is a by-product of industrial coke production from pit coal, coke gas is created by high-temperature dry distillation of coking coals in the absence of oxygen. The gas mainly consists of hydrogen (50-60%), methane (15-50%) and a small percentage of carbon monoxide, carbon and nitrogen.

18 hours to produce blast furnace coke and 25 to 30 hours to produce foundry coke. The coking time is determined by the coal mixture, moisture content, rate of underfiring, and the desired properties of the coke. When demand for coke is low, coking times can be extended to 24 hours for blast furnace coke and to 48 hours for foundry coke.

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 ...

Big coke lumps and low amounts of carbonaceous fines are necessary for a good permeability and drainage of liquid products. Coke size must not be less than 40 mm (40-60 or 40-80 mm).. The average coke diameter should be higher for large blast furnaces. Coke with a narrow size is used in order to achieve an optimal gas distribution.

Metallurgical coke is an important raw material for pig iron production in the blast furnace. During this process the coke undergoes severe mechanical, thermal and chemical stresses. One of these is the CO2 -gasification which may lead to a decisive mechanical weakening of the lump coke by increased carbon burn-off.
