The foundry industry may encounter problems such as white cast iron in casting. How to solve this problem has become a key issue. At this time, choosing low-carbon, low-nitrogen and carbon additives is a good option. So, what are the characteristics of low-carbon, low-nitrogen and carbon additives?
First, the low-carbon and low-nitrogen carbon additive has a moderate particle size, large porosity and fast absorption speed.
In addition, this product has a good degree of graphitization, which enhances the nucleation ability of the original molten iron. The number of graphite spheres in ductile iron can be increased, and graphite nuclei can be added to the molten iron in the electric furnace.
The third point is also the key to the excellent and stable performance of low-carbon and low-nitrogen carbon additives.
The fourth point is that graphite is evenly distributed in the casting.
Finally, petroleum coke is subjected to high-temperature baking, resulting in pure chemical composition and very few harmful components.
