Semi Coke

Semi coke is made from high grade Jurassic coal and as a new type of carbon material. It is characterized by high fixed carbon, high specific resistance, high chemical activity, low ash content, low sulfur and Low phosphorus, and is wildly applied to such industries as chemical industry, metallurgic industry, gas-making industry, etc.; used to produce calcium carbide, ferro alloys,  fertilizer

– Advantage of semi coke than Met Coke in production of Ferro-alloy smelting as deoxidizer

• High fixed carbon (84% max)

• Low ash (9% max)

• Low Phosphorus (0.03% max)

• Low Sulfur (0.4%max)

• high specific resistance

• high chemical activity

• High conductivity to lower the electric power

• Reduce pollution

– Advantage of semi coke than Met Coke in production of Ferro-alloy smelting as deoxidizer

(1),Semi Coke could improve the quality of the ferroalloy significantly (especially low aluminum alloy Al2O3≤0.1%).

(2),Semi Coke could reduce unit electricity consumption significantly (nearly save more than 1000 KWHR, that means 8-10%)

(3), Semi coke could lower the cost of raw material. Although the price of semi coke and coke is similar, but it’s far cheaper than charcoal and pet-coke

(4),It’s very simple to replace coke, pet-coke and charcoal with semi coke. It’s no need to upgrade your equipment and the operation is easy and process is simple.
