Calcined Needle Coke Used in Steelmaking of High Power and Ultra High Power Graphite Electrode CNC

Short Description:

Calcined needle coke is significantly different from sponge coke in property, with high density, high purity, high strength, low sulfur content, low ablative capacity, low thermal expansion coefficient and good thermal shock resistance. There are obvious anisotropy in heat conduction, electricity conduction, magnetic permeability and optics. The hole is large but less, slightly elliptical, the fracture surface has a clear texture structure, and the touch has a sense of lubrication. Calcined needle coke is mainly prepared from residue with high aromatics content and low non-hydrocarbon impurity content. Calcined needle coke: has obvious needle structure and fiber texture, mainly used in steelmaking of high power and ultra high power graphite electrode.Welcome to inquire
