graphite column carburizer for ductile iron casting

Foundry column graphite carburizing agentDuring smelting or casting, factors such as high-temperature oxidation and burn-off can lead to carbon loss. Steel mill columnar graphite carbon raiser can precisely replenish carbon content and promote graphitization of molten iron. Graphite column pellet carburant  also enhance the mechanical properties of steel and castings.Advantages of columnar graphite carburizerHigh Absorption Rate: Graphite column carburizer  has a high absorption rate, far exceeding that of coal-based and petroleum coke-based carbon additives.Low Sulfur and Nitrogen Content: Column graphite carbon raiser  has very low sulfur and nitrogen content, making it particularly suitable for high-end castings such as ductile iron.Promotes Graphitization of Molten Iron: Carbon atoms form an ordered, layered graphite structure, which effectively refines and homogenizes the distribution of graphite.Columnar Structure: The carbon additive has good flowability and does not clog the fe…
