Product Description

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

In the smelting process of iron and steel products, due to factors such as smelting time, holding time, and longer overheating time, the smelting loss of carbon in the molten iron increases, resulting in a decrease in the carbon content in the molten iron. The carbon content in molten iron cannot reach the theoretical value expected for refining.The carbon-containing substances added in order to make up for the carbon content burnt in the steel smelting process are called recarburizers.
The fixed carbon content of the recarburizer must not be too low, otherwise, to reach a certain carbon content, it is necessary to add more than the high-carbon recarburizer, which will undoubtedly increase the amount of other unfavorable elements in the recarburizer , So that the molten iron cannot obtain better returns.
 
In the metal smelting process, due to improper ingredients or charging and excessive decarburization and other reasons, sometimes the content of steel or iron does not meet the expected requirements. At this time, carbon is added to the steel or molten iron. The main substances used to increase carbon are anthracite powder, carbonized pig iron, electrode powder, petroleum coke powder, pitch powder, charcoal powder and coke powder. The requirement for the recarburizer is that the higher the fixed carbon, the better, and the lower the content of harmful impurities such as ash, volatile and sulfur, the better, so as not to pollute the molten iron.
In addition, the recarburizer needs other indicators, such as moisture, ash, and volatile content, the lower the amount of fixed carbon, the higher the amount of fixed carbon, the content of these harmful components will not be high.
There are many materials that can be used as cast iron recarburizers. Commonly used are artificial graphite, calcined petroleum coke, natural graphite, coke, anthracite, and mixtures made of these materials. Among the above-mentioned recarburizers, the best quality is artificial graphite.
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.
 
Production Process

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

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.
