0.2-1mm Metallurgical Graphite Petroleum Coke

This 0.2-1mm metallurgical graphite petroleum coke is one of our core carbon raiser grades. It is custom-made to meet melting demands in metallurgy, foundry and steelmaking industries. Raw petroleum coke undergoes full high-temperature graphitization treatment, then multi-stage screening to get particles within the 0.2–1mm range. The final product has uniform and clean grains, with excess fine powder and oversized impurities removed.

This particle size matches regular feeding routines for induction furnaces and electric arc furnaces, and it is widely adopted for steady carbon addition in smelting workshops. The grain size balances sinking speed and contact area with molten metal, maintaining stable reaction performance in molten steel and iron. It helps operators control the whole melting process, and fits well for ductile iron casting and special steel melting where carbon raw materials are held to high standards.

It has sufficient graphitization degree and good carbon activity. Once added into molten steel or iron, it gets absorbed smoothly and will not float on the melt surface for a long time. The 0.2–1mm size range is highly practical for metallurgical carbon raising. It avoids heavy dust issues brought by ultra-fine powder and slow dissolution caused by oversize grains.

Impurities are well controlled. It introduces very few unwanted components into the melt and reduces the risk of inclusions and internal defects in castings and steel parts. Thorough screening guarantees consistent particle conditions batch by batch, so you can expect reliable performance every time you feed it.

The particles feature a dense and solid structure. They are not easy to break during transportation and feeding, so few extra fine fines are generated. This cuts unnecessary material loss and eases dust troubles in the workshop.

The medium particle size brings steady sinking speed. After charging into molten metal, it takes part in carbon raising reactions continuously and predictably. Operators can control carbon content more easily and avoid repeated feeding and frequent adjustments.

It works with various feeding methods, including manual feeding and automatic silo feeding, with little risk of blockage.

Compared with ultra-fine carbon raisers, it generates less dust for a better working environment. Compared with large-grain carbon materials, it dissolves faster and suits furnace heats with shorter melting cycles.

Stable quality for the same grade means you do not have to change melting parameters frequently in long-term use. It helps factories lock in mature and fixed production procedures.

Flexible packing solutions are available, including standard bags and jumbo bags. They are convenient for warehouse storage, local transport, and fit the shift-based material picking system in plants.

Application

It is mainly applied in metallurgy and foundry sectors. It is most popular for ductile iron production, and widely used for carbon adjustment during carbon steel and alloy steel melting.

It fits induction furnace melting processes, and is also selected for refining procedures in many electric arc furnaces.

It adjusts carbon composition in molten iron and steel, optimizes metal microstructure, and helps improve the mechanical properties of castings.

This grade of graphite petroleum coke is also used as a carbon source component in formulas of some refractory materials and carbon composite materials.

If you are sourcing 0.2-1mm graphite petroleum coke, tell us your furnace type, finished products and your feedback on the carbon raiser you are using now. We will offer proper suggestions based on your actual working conditions.

Samples can be arranged for delivery. You can run furnace tests on site to check absorption effect and dust performance before confirming bulk orders.

We maintain regular stock for this grade. Long-term cooperation orders get priority shipment to reduce the risk of production shutdown caused by material shortage.

Feel free to contact us anytime if you run into questions during application. We can discuss and adjust feeding methods and operation details together.

If you have special requirements on label design, packing type or shipment schedule, inform us in advance and we will try our best to accommodate.
