In the prebaked anode calcination process control, it is required that the powder coke content in petroleum coke should be low, and the petroleum coke should have a certain particle size, not only to reduce burning loss and increase the actual yield, but also petroleum coke with high powder coke content is easy to cause Blockage of the material outlet of the equipment, coking in the tank, blasting of the furnace body, shed materials, etc., lead to early damage to the furnace body, over-burning, and loose and easy pulverization of the coke after calcination, which affects the life of the calcination furnace and the quality of calcination. At the same time, the content of petroleum coke powder coke increases, which makes the distribution of aggregates of various sizes after crushing and screening unstable, which affects the quality of the final prebaked anode.
