Problems solved by technology

[0004] The object of the present invention is to invent a method for increasing the number of cycles of carbon black, so as to solve the problem that carbon black cannot be kept in a loose state, so that the service life is short and the number of cycles is small, which leads to the use of carbon black as a graphitization furnace The problem of high production cost caused by high-quality insulation materials

Embodiment 1

[0021] To the furnace bottom of the graphitization furnace, add thermal insulation materials with a total volume of 20m long × 3.7m wide × 0.75m high. The thermal insulation materials include N330 wet-process carbon black and carbon multi-ash square, wherein the total volume of carbon multi-ash square is 1 / 3 of the total volume of the thermal insulation material, the method comprises the following steps:

[0022] S1. Prepare a carbon multi-gray square with uniform size, and its preparation method is:

[0023] ① Purchase a finished product with a cross-sectional area of ​​200mm×200mm and a height of 2m.

[0024] ② Use a cutting lathe to evenly divide the whole multi-gray square to obtain multiple carbon multi-gray squares with a cross-sectional area of ​​200mm×200mm and a height of 500mm;

[0025] ③Collect the carbon multi-ash square obtained after the segmentation, and transport it to the graphitization furnace for standby;

[0026] S2. After the graphitization furnace is co...

Embodiment 2

[0029] The difference between the first embodiment and the second embodiment is that: the total volume of the carbon multi-ash square added to the heat preservation material of the graphitization furnace is different.

[0030] To the furnace bottom of the graphitization furnace, add thermal insulation materials with a total volume of 20m long × 3.7m wide × 0.75m high. The thermal insulation materials include N330 wet-process carbon black and carbon multi-ash square, wherein the total volume of carbon multi-ash square is 1 / 4 of the total volume of the insulation material, the method comprises the following steps:

[0031] S1. Prepare a carbon multi-gray square with uniform size, and its preparation method is:

[0032] ① Purchase a finished product with a cross-sectional area of ​​200mm×200mm and a height of 2m.

[0033] ② Use a cutting lathe to evenly divide the whole multi-gray square to obtain multiple carbon multi-gray squares with a cross-sectional area of ​​200mm×200mm an...

Abstract

The invention discloses a method for increasing the number of cycle use of carbon black. According to the method, carbon with high ash content is added into insulation material carbon black at the bottom of a graphitization furnace to keep the loose state of the carbon black in the production process, thereby better guaranteeing insulation effects of the carbon black, greatly prolonging service life of the carbon black, increasing the number of cycle use of the carbon black and reducing production cost. The method has simple principle and is easy to implement, and meanwhile, the method has theadvantages that the defect that the carbon black can not be well maintained in the loose state during the production process is overcome, and the problems that the carbon black has less cycle use, short service life and the like are solved.

Description

technical field [0001] The invention relates to the field of graphitization technology, in particular to a method for increasing the cycle times of carbon black. Background technique [0002] As we all know, in the graphitization production process of negative electrode materials, carbon black is the first choice for furnace bottom insulation material. Carbon black can not only withstand high temperatures above 3000 degrees, but also play a good insulating role, and is a good auxiliary material in the production of the entire negative electrode material. However, any material faces consumption issues during the production process, and carbon black is no different. When the number of cycles reaches more than 8 times, the insulation of carbon black is reduced, so that it needs to be replaced or supplemented with new carbon black, and the price of carbon black is very expensive, causing the production cost to be too high; moreover, through the observation of daily production ...
