1. The processing materials are ultrafine granule structure, high purity and graphite with high graphitization degree.
2. High hardness, good anti-oxidation performance and high machining accuracy
3. Good conductivity, high resistivity, sufficient mechanical strength
4. Small porosity and dense structure.
5. Excellent thermal shock resistance, conductive and thermal conductivity.
6. High temperature resistance, corrosion resistance, acid and alkali resistance, good wear resistance.
7. Surface can be treated with anti-oxidation.



Graphite box (graphite boat) 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 box is made of artificial graphite by mechanical processing. So sometimes it's called a graphite box, sometimes it's called a graphite boat. The graphite box 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.
 

1. Thermal stability: for the use of hot and cold conditions, special treatment to ensure the reliability of product quality.
2. Corrosion resistance: uniform and fine material structure, delay the erosion of the use of degrees.
3. impact resistance: the ability to withstand high thermal shock, so the process can be assured.
4.Acid resistance: the addition of special materials significantly improved the physical properties of the material, excellent performance in terms of acid resistance, and greatly extend the service life of graphite.
5. High thermal conductivity: high content of fixed carbon ensures good thermal conductivity, shortens dissolution time, and significantly reduces energy consumption.
6. Pollution control: strict control of the material composition, to ensure that the pollution of the material greatly reduced.
7. Quality stability: uniform static pressing forming technology, process and quality control system more fully ensure the stability of the material.
8. Advanced processing technology, tolerance and appearance are better than customer standards;
9. With professionals who are familiar with customers' related industries, they can provide professional customization and supporting services.



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.
