AI Technical Summary
Technical Problem
The existing graphitization production process has a long production cycle and high energy consumption, resulting in low production efficiency of artificial graphite.
Method used
A continuous graphitization furnace is adopted to achieve a continuous graphitization process by controlling the particle size, preheating temperature and inert gas atmosphere of the raw materials, which shortens the production cycle and reduces energy consumption.
Benefits of technology
It effectively shortens the production cycle of artificial graphite, improves production capacity, reduces energy consumption, and improves the degree of graphitization and purity of the product.

Abstract
The invention discloses artificial graphite and a preparation method thereof, a negative pole piece, a battery and electric equipment. The preparation method comprises the steps that raw materials are put into a graphitization furnace, the raw materials comprise carbon particles, the particle size of the carbon particles ranges from 1 cm to 8 cm, and the graphitization furnace works in the inert gas atmosphere; the raw materials are controlled to enter a preheating zone of the graphitization furnace, so that the raw materials are preheated, and the temperature of the preheating zone is 800-1500 DEG C; feeding the preheated material into a graphitization area of a graphitization furnace so as to carry out graphitization treatment on the preheated material; and feeding the graphitized material into a cooling area of the graphitization furnace so as to cool the graphitized material. In the implementation mode, the graphitization process is continuous, the procedures do not need to be stopped and switched, all the procedures are carried out in the same graphitization furnace, the production period is shortened, and the productivity can be improved.
