Graphite sagger (graphite box) itself is a carrier, we can put the raw materials and parts we need to locate or finalize the design together in which high temperature sintering molding. Graphite sagger is made of artificial graphite by mechanical processing. So sometimes it's called a graphite box, sometimes it's called a graphite sagger. The graphite sagger is mainly used in various vacuum resistance furnaces, induction furnaces, sintering furnaces, brazing furnaces, ion nitridation furnaces, tantalum niobium smelting furnaces, vacuum quenching furnaces, etc.
 

The application of graphite sagger in porous carbon production mainly includes the following aspects:

1. As a reaction vessel: The preparation of porous carbon usually needs to be carried out under high temperature and other conditions. Graphite sagger has the characteristics of high temperature resistance, oxidation resistance and strong chemical stability. It can withstand extreme conditions in the preparation process and provide a stable reaction environment for the formation of porous carbon, ensuring the smooth progress of key steps such as pyrolysis and activation.

2. Promote the formation of carbon materials: Graphite itself has a certain catalytic effect. In the preparation process of porous carbon, graphite sagger can promote the formation of carbon materials, help improve the crystallinity and conductivity of porous carbon, thereby optimizing the performance of porous carbon and making it more suitable for use in energy storage and other fields.
Ensure product purity: The chemical stability of graphite sagger can effectively prevent the introduction of impurities in the reaction process and ensure the purity and quality of porous carbon, which is crucial for its application in high-performance batteries, catalyst carriers and other fields with high purity requirements.

3. Control the reaction atmosphere: Graphite sagger can adjust the reaction atmosphere to a certain extent, which helps to control the pore structure and surface properties of porous carbon. For example, in some preparation processes, the pyrolysis and activation process of carbon materials can be affected by controlling the gas composition and pressure in the sagger, thereby achieving the regulation of the pore size, shape and distribution of porous carbon to meet the requirements of porous carbon performance in different application scenarios.

4. Achieve large-scale production: Graphite saggers have good thermal conductivity and temperature uniformity, which can make the reaction materials evenly heated in the sagger, which is conducive to the stability and consistency of the quality of porous carbon products in large-scale production. At the same time, the reusability of graphite saggers also reduces production costs, improves production efficiency, and promotes the large-scale production of porous carbon.



1. The columns of the graphite box must be vertical and stable: the columns of the graphite box must be supported by fire-resistant clips to prevent them from swaying at high temperatures. The graphite box column on the outer ring shall not be inclined to the kiln wall, but may be slightly inclined to the center of the kiln.

2. After filling the kiln, seal the kiln door: the kiln door should preferably be built with refractory bricks on the inner and outer layers. The inner layer should be flush with the inner wall of the kiln wall, and the outer layer should be flush with the outer wall of the kiln wall, and each layer should be painted. Fire clay. When building the kiln door, leave a fire observation hole, and the position of the fire observation hole should be fixed every time the kiln is installed to avoid sudden high and low, large and small, which will affect the correct temperature measurement.

3. The height of the graphite box column: it should be determined according to the kiln structure and the temperature rise of various parts in the kiln. In general, the graphite box column near the vent should be lower to reduce the resistance of the flame to rise. Although the graphite box column in the middle can be taller, there should be enough space between the top of the kiln and the rising flames to converge here, and then redistribute them to the fire channels of the fire absorbing holes.

1. Flatten channels and reduce procurement costs. Our company is responsible for the entire link of raw material production-graphite box processing-graphite box sales, which can reduce customer procurement costs.
2. Appropriate graphite raw material size, less waste and low material cost. Our company's fine-grained high-density graphite is currently the most suitable material for graphite cartridge production, with high quality, low price and high cost performance.
3. The processing cycle is short, which can meet the timeliness requirements of customers. Our company is a professional manufacturer of graphite cartridges, with a monthly production capacity of 10,000, which is better than the customer's processing accuracy requirements, and the delivery is timely. It is widely praised by customers at home and abroad.
