What is Semi Coke?



Semi coke production in China(also called gas coke) is made of high quality jurassic coal briquettes which can be found in the Shenfu coalfield. As a new type of carbon material, it has attractive properties of high fixed carbon, high specific resistivity, high chemical activity , low ash content, low Aluminum, low sulphur, and low phosphorus. It has gradually replaced metallurgical coke anthracite and charcoal. As an irreplaceable carbon material, it has been widely used in producing Calcium Carbide, Silicon Metal, Ferroalloy, Silicon Iron, Silicomanganese, Carborundum, and so on. Moreover, it can also replace a fairly large number of anthracite and hard coke applications in the area of blast furnace injection, producing charring materials and activated carbon. 

Application of the Semi Coke production in China Supplied by Rongxing



The semi coke production in China supplied by Rongxing Group is used in blast furnace instead of coal injection in steel-making.

0-6mm semi coke will be used for sintering Mn ore in process of production SiMn; or using in other sinter mill.

6-18mm semi coke will be used in producing Ferronickel , Ferrosilicon ,Calcium Carbide and other ferroalloys.


Semi Coke production in China Small Material Specification Parameters

    Size                 18-30mm

    Ash                      ≤8%  
    Sulphur                  ≤ 0.40%-0.50%
    Moisture                 10-15%
    Phosphorus               ≤0.012%
    w(k+Na)                ≤0.2%


Advantage of Rongxing Semi Coke production in China

We mainly supply Semi Coke, electrode paste and other Industry products. We focus on Ferroalloys industry such as Fesi Plant,FeNi Plant,Calcium Carbide plant and Steel Making Industry. As our main product, semi coke has advantage of low ash, low sulfur and low phosphorus, high fixed carbon, high electrical resistance and high re-activity. It can reduce unit ton electric power consumption more than 2000 Degree than metallurgical coke, and can improve ferroalloys products quality because of low sulfur and low phosphorus.Our unit ton power consumption for fesi 75% can lower than 8300 degree.


What should we pay attention to when using semi coke?

1. Semi coke should have rainproof measures during storage to avoid damp rain.
2. Stove that uses semi coke should not communicate with the bedroom as much as possible to prevent gas poisoning.
3. During the use of semi coke, regularly clean the flue to ensure the full combustion of semi coke.
4. Add enough coal at one time. Add coal in the middle and late period of combustion to prevent the furnace temperature from being too low and extinguishing the fire.
5. The height and diameter of the chimney must be ensured, and the chimney interface and the chimney itself must not leak (the chimney is too low or too thin will cause the heating furnace to not burn normally, seal the fire and extinguish the fire, etc.).
6. Adjust the size of the air inlet on the dust removal door according to the situation when sealing the furnace, to prevent the situation that the fire can not be sealed or extinguished when the furnace is sealed.
7. If a chimney hat is added, the hat should be more than 50 cm away from the mouth of the chimney.
