Granular petroleum coke is hard and granular, which is prepared by delayed coking method with high content of sulfur and asphaltene, and is mainly used as fuel.
The fluidized petroleum coke is prepared by continuous coking in the fluidized bed, which is fine and granular, the structure is non-directional, the sulfur content is high and the volatile content is low.
Petroleum coke is calcined to remove sulfur, moisture, and volatile matter.
Calcining raw petroleum coke at 1200 ℃ 1350 ℃ can make it become basically pure carbon.
Calcined petroleum coke is used by the aluminum industry, 70% of which is used to make anodes that reduce bauxite.
About 6% of the calcined petroleum coke produced in the United States is used as a carburizer for cast iron.
Natural graphite can be divided into two types: flake graphite and microcrystalline graphite.
Microcrystalline graphite has high ash content and is generally not used as carburizing agent for cast iron.
There are many kinds of flake graphite: high carbon flake graphite needs to be extracted by chemical method, or heated to high temperature to decompose and volatilize the oxides.
The ash content in low carbon flake graphite is high, so it is not suitable to be used as carburizer, and medium carbon graphite is mainly used as carburizer, but the dosage is not much.
Coke and anthracite.
In the steelmaking process of calcined petroleum coke arc furnace, coke or anthracite can be added as carburizing agent.
Because of its high ash and volatile content, calcined petroleum coke is rarely used as a carburizing agent for smelting cast iron in induction furnace.
