Carbon Raiser
There are two types of carbon additive. One is Carbon Additive and the other is Low Nitrogen Carbon Additive . According to the different refining methods, carbon additive will increase and affect the strength of steel and casting during founding. YUAI has a lot of experience in dealing with carbon additive. The group ensures to provide the best quality of carbon additive to customers. We never stop innovating for better product.

Due to different levels of absorbility, Carbon Additive will be differentiated into specific products which are Pitch Coke, Calcined Petroleum Coke and Anthracite. We conclude that Pitch Coke has the highest level of absorbility, which is the best founding.

 
Pitch Coke

Pitch Coke is extracted from coke tar by BAOSTEEL Co., Ltd., which contains higher level of carbon, very low level of sulfur and nitrogen. Compared with calcined petroleum coke, pitch coke is stronger and easier for graphitizing. As a result, it can be considered as the best raw material for Special Carbon Products.

 
Calcined Petroleum Coke

Calcined Petroleum Coke comes from delayed coke which extracted from oil refinery. Although Calcined Petroleum Coke contains higher level of sulfur and nitrogen, the price advantage makes it still use widely during steel-making and founding as a kind of carbon additive.

 
Coaly Carbon Additive

Coaly Carbon Additive is processed and calcined from washed lump coal from Ningxia. Coaly Carbon Additive has the lowest level of carbon containing which usually is 95%. However, the lowest price makes it still competitive in steel-making.

 
Low N Calcined Petroleum Coke
The Low N Calcined Petroleum Coke which operating and by our company is processing at a higher temperature from Pitch Coke. Due to a different processing method, compared Calcined Petroleum Coke and Pitch Coke, it contains lower nitrogen, lower sulfur and high fix carbon. Low N Calcined Petroleum Coke processing by our company can be considered as one of the best CPC.
