What is meant by nut coke?
Nut coke is low ash metallurgical coke of smaller grain size. It is used in smelters and in the production of ferro alloys. Nut coke is used in blast furnaces to increase productivity and achieve cost savings.
How is nut coke made?
In conventional ironmaking practice, ferrous burden (iron ore, sinter and pellets) and regular coke are charged in alternate layers. Strict quality and size demand for regular coke layer results in the generation of undersize coke, i.e. size < 40 mm also known as nut coke.
What is size of nut coke?
Nut coke (size < 40 mm) is charged in mixture with the ferrous burden in the blast furnace to take advantage of better permeability, enhanced reduction kinetics and to lower the expensive regular coke requirement during smelting. Nut coke is charged in wide range of size 10 – 40 mm and concentration from 2 – 35 %.
How the quality of coke does effects the reaction of a blast furnace?
Blast temperature is other parameter which influences the coke rate in a blast furnace. Blast furnace coke rate reduces by around 2 % with the blast temperature increasing by 100 deg C. High top pressure also reduces the coke rate in the blast furnace.
What is metallurgical coke?
Metallurgical coke is produced by destructive distillation of coal in coke ovens. The material remaining is called coke. Most metallurgical coke is used in iron and steel industry processes such as blast furnaces, sinter plants, and foundries to reduce iron ore to iron.
What are the qualities of coke?
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process.
Where is nut coke used in the world?
It is used in smelters and in the production of ferro alloys. Nut coke is used in blast furnaces to increase productivity and achieve cost savings. FCS supplies high quality, low ash nut coke from China, Poland, Colombia and Ukraine. Typical cargo specifications:
What kind of nut is in Coca Cola?
These days, the Coca-Cola recipe is a closely guarded secret, but it’s said to no longer contain kola nut extract
Where can I find low ash nut coke?
Nut coke is low ash metallurgical coke of smaller grain size. It is used in smelters and in the production of ferro alloys. Nut coke is used in blast furnaces to increase productivity and achieve cost savings. SOURCES: FCS supplies high quality, low ash nut coke from China, Poland, Colombia and Ukraine.
Which is better nut coke or regular Coke?
In recent past, it has been discovered that small amount of nut coke mixed with ferrous burden leads to better reduction kinetics, lower reductant consumption, and better gas and liquid permeability. Nut coke is charged as a replacement of the regular BF coke.
