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 an insulating material with a total volume of 20m long × 3.7m wide × 0.75m high. The insulating material includes N330 type wet carbon black and carbon multi-ash square, wherein the total volume of adding 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 cooled, plac...

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 an insulating material with a total volume of 20m long × 3.7m wide × 0.75m high. The insulating material includes N330 type wet carbon black and carbon multi-ash square, wherein the total volume of adding 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 and a height...

Abstract

The invention discloses a method for increasing the cycle times of carbon black. By adding carbon multi-ash square to the heat-insulating material carbon black at the bottom of the graphitization furnace, the loose state of the carbon black in the production process is kept, thereby better ensuring It improves the insulation effect of carbon black, greatly prolongs the service life of carbon black, increases the number of cycles of carbon black, and reduces production costs. The principle of the invention is simple and easy to implement. It plays a very good role in overcoming the current defect that the carbon black cannot be kept in a loose state in the production process, and solving the problems of less cycle times of carbon black and short service life of carbon black. Effect.

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 ...
