Injection Carbon And Semi-coke
Injection carbon is a carbon material used in blast furnace injection processes. Its primary component is fixed carbon. It partially replaces pulverized coal, improving combustion efficiency and molten iron quality. It is commonly used in steelmaking. Semi-coke, a solid product obtained by low-temperature dry distillation of coal, has a high fixed carbon content and low volatile matter content. It is widely used as a reducing agent or fuel in industries such as calcium carbide, ferrosilicon, and steel.
Applications
Injection Carbon for Electric Arc Furnace Steelmaking
Used as a carbon source for injection in electric arc furnaces, it promotes foamy slag formation, improves thermal efficiency, and reduces electrode wear.
Injection Carbon for Blast Furnace Injection
As a pulverized coal alternative, it improves combustion efficiency, reduces the coke ratio, and optimizes blast furnace operating costs.
Semi-coke for Ferroalloy Smelting
As a reducing agent and carbon source, it is suitable for electric furnaces for alloys such as ferrosilicon and ferromanganese, offering high reaction efficiency and low impurities.
Semi-coke for Calcium Carbide Production
Used as a partial coke replacement, it improves reaction stability and calcium carbide output efficiency and is compatible with most calcium carbide furnace systems.
Semi-coke for Blast Furnace Fuel Replacement
As an auxiliary fuel, it reduces coke consumption while maintaining a reducing atmosphere, helping to control costs and emissions.

FAQ
Q: Can injection carbon be used directly for blast furnace injection?
A: Yes, injection carbon is suitable for blast furnace injection, improving combustion efficiency and molten iron quality.
Q: What is the difference between semi-coke and regular coal?
A: Semi-coke undergoes low-temperature dry distillation, resulting in a higher fixed carbon content and lower volatile matter, making it suitable for use as a reducing agent and fuel in metallurgy.
Q: How do I choose the injection carbon that suits my process?
A: Select injection carbon with the appropriate particle size and carbon content based on the injection equipment and smelting process requirements.
Q: What are the storage requirements for semi-coke?
A: It should be kept dry and well ventilated to avoid moisture and impurities that may affect combustion and reaction performance.
Q: Can injection carbon and semi-coke replace coke?
A: They can partially replace coke and reduce coke consumption, but their use must be tailored to the specific process.
