Casting is the foundation of industry, and material is the core of casting. Hunan Xintan New Materials Co., Ltd. produces graphitized petroleum coke recarburizer and supplies flake graphite, slag remover, ferroalloy and other materials in the casting industry enjoy a high brand awareness.
Graphite petroleum coke recarburizer is produced by graphitization at high temperature of 3000℃. Featuring good graphite nucleation, It is the preferred carbonizing material for casting industry, especially ductile iron casting. For the casting industry, there are many materials for carbon raiser, such as anthracite, calcined petroleum coke, etc., but the types of casting are not the same, and the types of carbonizing are different. Generally speaking, gray iron casting is not so strict on the sulfur content of recarburizer, and anthracite and calcined petroleum coke carburants can be selected.Ductile iron has strict requirement for sulphur .The carbon content of graphitized recarburizer produced by Xintan New Materials Co., Ltd. is stable at more than 99%, and the sulfur content can be less than 0.01%. Through the furnace bottom or the furnace layer by layer of carburizing or the furnace outside the carbon, the absorption rate of carbon in hot metal is greatly improved, so as to better improve the mechanical properties of castings.
Flake graphite has the characteristics of high temperature resistance and lubricant, casting mold and casting surface add flake graphite, so that the casting is easy to release, in the process of casting industry production, casting process is carried out in a high temperature environment, in order to make the casting at high temperature without deformation, without fracture, it is necessary to add special casting flake graphite, casting material after adding flake graphite, can withstand high temperature, Ensure the quality of castings.
