Coke Coal Use

Coking coal (metallurgical coal) is an vital industrial uncooked material, mostly used to produce coke, which in flip helps metal and different heavy industries. The following are its most important makes use of and sub-sectors

  1. Steel smelting (core use)

Coke production: Coking coal is distilled at excessive temperature (heated to extra than 1000°C in air isolation) to produce coke. Coke performs a twin function in the blast furnace:

Reducing agent: reacts with iron ore to decrease iron oxide to steel iron.

Fuel: Combustion gives high-temperature warmth (maintaining about 1500°C in the blast furnace).

Steelmaking process: Coke money owed for 70%-80% of the uncooked substances in the blast furnace, which without delay impacts the satisfactory and manufacturing effectivity of steel.

  2. Foundry industry

Chocolate furnace fuel: Coke is used to soften metallic uncooked substances such as pig iron and scrap metal to produce castings.

Characteristic requirements: Coke for casting desires to be low in sulfur and ash to limit impurities in castings.

  3. Chemical Industry and Energy

Coal Gasification: Coking coal can be gasified to generate synthesis fuel (CO+H₂), which is used to produce chemical merchandise such as methanol and artificial ammonia.

Calcium Carbide Production: Coke and limestone react in an electric powered furnace to generate calcium carbide (CaC₂), which is similarly used to make acetylene (used for slicing and welding, PVC plastics, etc.).

  4. Non-ferrous Metal Smelting

Reducing Agent: In the smelting of copper, lead, zinc and different metals, coke is used as a lowering agent to extract pure metals.

Fuel: Provides the excessive temperature required for smelting.

  5. Other Industrial Applications

Carbon Materials: Coke can be processed into graphite electrodes (used for electric powered arc furnace steelmaking), carbon products, etc.

Fuel Supplementation: Low-quality coking coal or coke powder can be used as industrial boiler gas (non-mainstream use).

  As "industrial food", the demand for coking coal is intently associated to industries such as metal and infrastructure, and is an essential indicator for measuring the heavy industrial economy.
