Equipment use: Vacuum carbon tube furnace is a high temperature, high vacuum
resistance furnace using graphite as a heating element. The maximum working
temperature can reach 2000 °C ~ 2400 °C. This series of products are widely used
in inorganic materials (such as ceramic seals, silicon carbide, zirconia, zinc
oxide, alumina, etc.), and metal materials (such as cemented carbide) sintered
in a vacuum or protective atmosphere, can also be used Purification of rare
earth elements and their oxides and sapphire annealing treatment. It is also
suitable for use in colleges and universities and research institutes for pilot
production.
Brief introduction of the structure: The electric furnace is a
vertical vacuum electric furnace, which is composed of a furnace cover, a
furnace body, a furnace bottom and a vacuum unit. The inner layer of the furnace
shell is stainless steel, and the outer layer is carbon steel, and the two
layers are cooled by water. The furnace shell is provided with an air suction
port, an observation hole, a thermocouple hole, a protective atmosphere inlet
and outlet, and an explosion-proof port. The furnace is equipped with a graphite
electrode, which is connected with the graphite heating element by a cylindrical
surface. One end of the electrode protrudes out of the furnace through a seal.
It is an important component for allowing current to pass through the heating
element in the furnace. The heat shield is surrounded by a multi-layer radiation
screen.
Features:
1. The circuit is equipped with water shut-off,
over-current, furnace over-temperature and water over-temperature alarm and
protection functions.
2. The furnace is equipped with an inflatable
overpressure explosion-proof system.
3. Compact structure and reasonable
layout.
4, humanized design, reasonable configuration.
