application of graphitized petroleum coke recarburizer

The smelting material with a relatively large amount of cast steelmaking needs to be graphitized petroleum coke recarburizer. Its raw material is firstly the waste residue generated by converting refined petroleum, which is destined to graphitized petroleum coke increase. The carbon agent has a good thermal energy effect. The petroleum coke is graphitized at high temperature, so only the widely used graphitized petroleum coke recarburizer is placed. It plays an irreplaceable role in the production process of steelmaking!

Production process of graphitized petroleum coke

Petroleum coke is a waste residue in the process of petroleum refining. Graphitization is the production process of processing petroleum coke into graphite by high temperature. In this process, petroleum coke will be energized and treated at a high temperature of 3000 degrees, so that the carbon molecular form of petroleum coke is irregularly separated The open method is transformed into a six-stage uniform alternating method. In this way, the petroleum coke can be better decomposed in the molten iron. Most of the mainstream carburetants on the market today are graphitized petroleum coke recarburizers.

Application of graphitized petroleum coke recarburizer

At present, the carburizing agent is generally suitable for electric furnace melting. There are also a few carburizing agents with a particularly fast absorption rate for cupola furnaces. For electric furnace melting, the carburizing agent should be placed in the furnace together with scrap steel and other charging materials in small doses. You can choose to add it to the surface of the molten iron, but you should avoid feeding large quantities into the molten iron to prevent excessive oxidation and the lack of carbon replenishment effect and insufficient carbon content of the casting. The amount of recarburizer is based on other raw materials. Depending on the proportion and carbon content, the characteristics of the recarburizer itself select pure carbon-containing graphitized substances to reduce excessive impurities in pig iron. The proper choice of recarburizer can reduce the production cost of castings.

Complex technology and good raw materials are the foundation to ensure the quality of graphitized petroleum coke recarburizers. At the same time, better graphitized petroleum coke recarburizers can play a better effect in steelmaking and casting. Of course, one cent of the price The principle of one point is still very popular. At present, the market price of good graphitized petroleum coke recarburizer is also relatively expensive, which also makes graphitized petroleum coke recarburizer only used in some superior varieties.
