Graphite Briquette Suppliergraphite briquette. In converter smelting, when high-carbon steel grades, petroleum coke with very few impurities is used as a recarburizer. The requirements for the recarburizer for top-blown converter steelmaking are high fixed carbon, low ash, volatile content and impurities such as sulfur, phosphorus, nitrogen, and dry, clean, and moderate particle size. graphite briquette supplier also use graphitized petroleum coke as materials of recarbonizer.
The recarburizer is used in casting, which can greatly increase the amount of scrap steel, reduce the amount of pig iron or not use pig iron. Most recarburizers are suitable for electric furnace smelting, and a small part of recarburizers with a particularly fast absorption rate are used in cupolas. In the feeding method of electric furnace smelting, the recarburizer should be put in with the scrap steel and other charge, and small doses can be added to the surface of the molten iron. However, it is necessary to avoid large quantities of materials into the molten iron to prevent excessive oxidation and the occurrence of insignificant recarburization effects and insufficient carbon content in castings. The amount of recarburizer is determined according to the ratio of other raw materials and the carbon content. For different types of cast iron, choose different types of recarburizers according to your needs. As graphite briquette supplier, the characteristics of our graphite briquette and graphite carbon ball product itself choose pure carbon-containing graphitized materials to reduce excessive impurities in the pig iron. Choosing appropriate recarburizers can reduce the production cost of castings.
There are many kinds of raw materials for recarburizers, and the production processes of different graphite briquette suppliers are also different. It is not said that graphite powder is used for compression molding. This production method requires the addition of too much binder for molding, and the carbon content generally does not meet the requirements of high-quality recarburizers. As a professional graphite briquette supplier, Anyang Huatuo uses high quality graphite powder to manufacture graphite briquette. Because the pressed graphite powder is a solid block and has no porous structure, the absorption speed and absorption rate are not as good as calcined, roasted and formed carbon increase Agent. High-quality graphite briquette recarburizer generally refers to a recarburizer that has undergone graphitization. Under high temperature conditions, the arrangement of carbon atoms is in the microscopic form of graphite, so it is called graphitization. Graphitization can reduce the content of impurities in the recarburizer, increase the carbon content of the recarburizer, and reduce the sulfur content.
