Product Description

Product Description

Graphitized petroleum coke

Xingshi New Materials supplies graphitized carbonization agents (Carbon Raiser for Industry)

Mainly containing graphitized petroleum coke( 100% Graphitized Petroleum Coke / Semi Graphitied Petroleum coke) and some artificial graphite(Synthetic Graphite Granule and powder) such as electrodes fines, graphite crucibles, anode block by-products, and scraps.

Production of the GPC (  Full Graphitized Petroleum Coke and Semi- Graphitized Petroleum coke )

After high-temperature "magic" treatment at 1800 ℃ -3000℃, the internal carbon atoms of graphitized petroleum coke transform from disordered to neatly arranged graphite structures - this is the birth process of graphitic petroleum coke carbonization agents.
 
Its core characteristics are high carbon, low sulfur, and low nitrogen. Far superior to ordinary calcined petroleum coke. This "refined" carburetor can not only supplement carbon efficiently, but also reduce defects such as porosity and slag inclusion in castings, which can be called the "golden supporting role" of the casting industry

Color and Gloss: Graphitic petroleum coke carbonization agents typically appear gray black or black in color, with a stronger metallic luster and a shiny black appearance. The enhancement of this luster is due to the more ordered arrangement of carbon atoms during the graphitization process. Formed a more compact structure.

Structure and texture: Graphitized petroleum coke carbonization agent has a porous structure, which helps to improve its specific surface area and reactivity, thus better exerting its carbonization effect in steelmaking and casting processes. Meanwhile, it usually has a certain degree of hardness and brittleness, and is not easily broken or deformed.

Applications

Graphitized Petroleum Coke(GPC Carbon Raiser) is used for steelmaking, casting, and smelting as a Carbon agent

√  Metallurgical industry: Graphitized petroleum coke is the best carbon additive for smelting, especially suitable for the steelmaking industry. It can effectively improve the quality of steel, reduce production costs, and promote the development of the steel industry.
 
√ Graphite product production: Graphitized petroleum coke (GPC 98% OR 99%) is a raw material for producing large cathode blocks, large carbon electrodes, graphite electrodes, and high-performance electrode pastes. At the same time, it can also replace some grinding and be used to manufacture high-tech products such as graphite emulsion, graphite sealing materials and composite materials, graphite anti-wear additives, etc.

√ Other industrial fields: Graphitized petroleum coke is also widely used in the chemical industry (as a reducing agent, casting reduction inoculant, refractory materials, etc.), mechanical industry (as a lubricant), electrical industry (carbon brush), battery industry (electrode), fertilizer industry (catalyst), friction material production (artificial graphite particle powder), and the production of high-temperature crucibles, electrodes, and pencil leads in smelting.

Features & Advantages

1. Improve casting performance and upgrade quality
The graphitized structure makes carbon more easily absorbed by molten iron, with an absorption rate of over 90%. It can refine the graphite morphology, enhance the tensile strength and hardness of castings, especially suitable for high-end products such as ductile iron and vermicular iron.

2. Reduce porosity defects and increase yield!
Ordinary carburizers have high sulfur and nitrogen content, which can easily cause porosity. The graphitization process can remove most impurities and control sulfur below 0.05%. Extremely low nitrogen content, reducing the risk of nitrogen porosity in castings from the source

3. Environmental protection, energy conservation, and green production
The low ash content characteristic (≤ 0.5%) reduces slag generation, lowers energy consumption and slag removal intensity, while reducing smoke and dust emissions, which is in line with environmental trends.
 
Half graphitized petroleum coke carbonization agent is a cost-effective Carbon raiser( Carbon additive), with lower sulfur content than petroleum coke carbonization agent, better effect than petroleum coke carbonization agent, but lower price than all graphite carbonization agent. The absorption rate is also a very high product. Both ductile iron and gray cast iron can be used.
Many foundries use semi graphite petroleum coke carbonization agents.

Packaging & Shipping

Storage: When the moisture content is less than 0.5%, the introduction of hydrogen gas in humid environments increases the risk of casting porosity.

Usage time

1. Temperature control: Low temperature carbonization, high temperature silicon adjustment
The best carbonization effect is achieved when the temperature of the molten iron is between 1460-1550 ℃. Excessive temperature can cause carbon burning. Therefore, it is recommended to complete carbonization in the low temperature stage during the early stage of melting, and then adjust the silicon content in the high temperature stage.

2. Particle size selection: Finer is not better
The particle size needs to match the furnace type: medium frequency furnace recommends 1-5mm graphite petroleum coke, which can dissolve quickly and avoid excessive oxidation. Particle uniformity also affects absorption efficiency, and powder and large particles need to be screened out.

3. Sulfur content:
The production of ductile iron requires strict control of sulfur content (S ≤ 0.015%), and it is necessary to use graphitized carburizers with sulfur content below 0.05%.

4. Nitrogen content
Nitrogen content exceeding 0.012% in gray cast iron is prone to porosity, and the type of carburizer needs to be adjusted according to the amount of scrap steel used
