Description

TECHNICAL FIELD

[0001] The utility model belongs to mixing device technical field, and specifically, it is especially related to a mixing device for petroleum coke composite carbon additive production. BACKGROUND

[0002] Petroleum coke composite carbon additive is an additive used in steel, casting and other industries, and its main function is to increase the carbon content in molten iron or molten steel. It is a product composed of petroleum coke as the main raw material, other carbonaceous materials and binders.
