Needle coke is a kind of calcined petroleum coke,its appearance is silver-gray, metallic luster porous solid. Its structure has obvious flow textureliking fibers or needles, large less elliptical shapeholes,big lengthwidth ratio particles,lubricated,low coefficient of thermal expansion.It is the raw material for producing ultra-high power graphite electrodesfor electric arc furnaces with strong thermal shock resistance,high mechanical strength,good anti-oxidation performance,low electrode consumption and high allowable current density.
