Graphite heater furnace

Release time：2022-02-19 Number of views：885

Equipment introduction:

NOBODY graphite heating furnace has compact structure and scientific design. The heating elements and insulation materials are made of high purity graphite materials with different densities, and the built-in infrared thermometer is used as the temperature measurement and control device. The equipment can reach 3000℃ in the protective gas environment. Preset 6 water-cooled circulation channels, which can effectively ensure the long-term stable operation of the equipment. It is widely used in graphitization, pyrolysis, silicification, tempering, brazing, degassing, carbonization, rapid prototyping, sintering, degreasing, synthesis and other experiments at ultra-high temperature.
