Product Introduction:
The KJ-VS1700-12CWG high-temperature graphite vacuum furnace uses graphite heating elements that are resistant to high temperatures and not easily deformed. The working temperature can reach 1700 ℃. The high-temperature vacuum furnace is equipped with a vacuum unit, which can achieve heat treatment of materials under high temperature and high vacuum. It is widely used for heat treatment of metal materials in high vacuum and protective atmosphere, and can also be used for heat treatment of special materials with good insulation properties such as carbide fibers.
