Product Description

High Quality Graphite Heating Rod, Combined Heater For High Temperature Vacuum Furnace
Product details:
Graphite heater become the indispensable parts of the high temperature furnace. The weight loss is small and thermal expansion coefficient is very small when burned by ultra-high temperature. The strength of graphite heater will increase with the increasing of temperature.
 
High Quality Graphite Heating Rod, Combined Heater For High Temperature Vacuum Furnace Features:
1. Thermal stability: according to the use conditions of hot and cold products, special design is made to ensure the reliability of product quality.
2. Erosion resistance: the uniform and fine matrix design delays the erosion degree of the product. Impact resistance: the product can withstand high thermal shock strength, so any process can be assured.
3. Acid resistance: the addition of special materials can significantly improve the quality of products, show excellent performance in acid resistance index, and greatly extend the service life of products.
4. High thermal conductivity: high content of fixed carbon ensures good thermal conductivity, reduces dissolution time and significantly reduces energy consumption.
5.Control of metal pollution: strict control of material composition ensures that the product does not pollute the metal when dissolved.
6. Quality stability: the manufacturing technology and quality assurance system of high pressure forming can more fully guarantee the quality stability.
