Semi-Coke

What Is Semi-Coke

Semi-coke from Rongxing Group is light black, characterized by high fixed carbon, high specific resistance, high chemical activity, low ash content, low sulfur, and Low phosphorus.

It is wildly applied to such industries as the chemical industry, metallurgic industry, and gas-making industry to produce calcium carbide, ferroalloy, ferrosilicon, silicon carbide, silicomanganese, fertilizer, etc. Semi coke is made from high-grade Jurassic coal as a new type of carbon material. It will substitute some metallurgical coke in producing ferroalloy products. Semi coke can be used in smelting too.

Raw Materials and Production

Our semi-coke is made from high-grade Jurassic coal and is a new type of carbon material. It can be instead of some metallurgical coke when producing ferroalloys products. Our semi-coke products are used in smelting too much in China currently.

Using CDQ technology to ensure low moisture, high fixed carbon, high heat, low sulfur, low phosphorus, low ash, high combustion efficiency of the semi coke, which is in line with environmental standards.

Main Applications

Semi coke powder can be used in blast furnace instead of coal injection in steel-making

Semi-coke (0-6mm) can be used for sintering Mn ore in process of production SiMn; or using in other sinter mills

Semi-coke (6-18mm) can be used in producing Ferronickel, Ferrosilicon, Calcium Carbide and other ferroalloys.

Using Guide

Semi-coke should have rainproof measures during storage to avoid damp rain.

The stove that uses semi-coke should not communicate with the bedroom as much as possible to prevent gas poisoning.

During the use of semi-coke, regularly clean the flue to ensure the full combustion of semi-coke.

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.

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.).

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.

If a chimney hat is added, the hat should be more than 50 cm away from the mouth of the chimney.
