China Wholesale High Purity Synthetic Recarburizer With Fixed Carbon Graphite Petroleum Coke

Petroleum coke is currently a widely used recarburizer.
Petroleum coke is a by-product of refining crude oil. Residues and petroleum pitches obtained by crude oil distillation under pressure or vacuum can be used as raw materials for making petroleum coke. After coking, raw petroleum coke can be obtained. The production of raw petroleum coke is less than 5% of the crude oil used. The annual output of raw petroleum coke in the United States is about 30 million tons. The raw petroleum coke has a high content of impurities and cannot be used directly as a recarburizer. It must be calcined first.
Raw petroleum coke comes in spongy, needle, granular and fluid forms.

Natural graphite can be divided into flake graphite and microcrystalline graphite.
Microcrystalline graphite has a high ash content and is generally not used as a recarburizer for cast iron.
There are many varieties of flake graphite: high-carbon flake graphite needs to be extracted by chemical methods, or heated to a high temperature to decompose and volatilize the oxides in it. This kind of flake graphite is not produced and expensive, and is generally not used as a recarburizer; low carbon flakes The ash content in graphite is high, so it is not suitable to be used as a recarburizer; medium carbon graphite is mainly used as a recarburizer, but the amount is not large.

Coke and anthracite
In the process of electric arc furnace steelmaking, coke or anthracite can be added as a recarburizer during charging. Due to its high ash and volatile content, induction furnace smelting cast iron is rarely used as a recarburizer.

The main raw material for manufacturing artificial graphite is powdered high-quality calcined petroleum coke, in which pitch is added as a binder, and a small amount of other auxiliary materials are added. After the various raw materials are matched, they are pressed into shapes, and then processed in a non-oxidizing atmosphere at 2500-3000°C to make them graphitized. After high temperature treatment, the ash, sulfur and gas content are greatly reduced.
Due to the high price of artificial graphite products, artificial graphite recarburizers commonly used in foundries are mostly recycled materials such as chips, waste electrodes and graphite blocks when manufacturing graphite electrodes to reduce production costs.
When smelting ductile iron, in order to make the metallurgical quality of the cast iron superior, artificial graphite should be the first choice for the recarburizer.
