Column carburizer/Columnar recarburizer
New Arrival Carbon Raiser Columnar Graphite Recarburizer 0.8*2cm
Its fixed carbon content is high, and the content of S, P and N is much lower than that of coal carburizing agent. Because of its good carburizing effect in smelting and casting, high carbon yield, stable effect and high cleanliness of molten steel, columnar graphite carburizing agent is deeply welcomed by the metallurgical industry. And it is the preferred high-quality material for carburizing and deoxidizing in the metallurgical industry.
Graphite instant columnar recarburizer refers to the change of molecular structure of carbon products through high temperature or other means, and has a regular arrangement. This molecular arrangement has a wider molecular spacing of carbon, which is more conducive to decomposition in molten iron or molten steel. nuclear. Graphite instant columnar recarburizers currently on the market generally come from two sources, one is the scrap cutting of graphite electrodes, and the other is the graphitized product of petroleum coke 3000 degrees.
Features:
- The particle size is moderate, the porosity is large, and the absorption speed is fast.
- The chemical composition is high in carbon, low in sulfur,extremely harmful and has high absorption rate.
- The graphite structure of the product is good, and the nucleation ability of the original molten iron is improved. In the gestation, the number of ink balls of ductile iron is increased, and the graphite crystal nucleus is added in the iron of the electric furnace. Refine and homogenize the distribution of graphite in the casting.
- Performance is stable.
The selection of suitable recarburizers can help reduce smelting production costs, improve the quality of smelting metals and castings, and allow smelting of metal plants and casting.
Application:
1) Used for steel making,can improve the Carbon content in steel-melting and Ductile iron foundry.
2) Mainly used in steelmaking in electrical stove, screening water, shipbuilding sandblast to remove rust.
3) Can reduce the cost of steelmaking effectively by replacing the traditional petroleum coke of carburant.
