Vacuum
Oven - Serves Industrial And Science
Vacuum oven
is a heat-treating oven that serves all industrial and scientific
purposes. It also uses a low atmospheric pressure instead of a
protective gas atmosphere. This quality helps to alleviate surface
reactions. Vacuum ovens also perform major functions like quenching,
sterilizing, aging, baking, brazing and soldiering, preheating,
curing, drying, foundry and melting, hot pressing, heat treating,
firing and sintering.
Features
of a Vacuum Oven
The vacuum oven is used for scientific purposes because it has
equipments, ideally suited for large scale and laboratory purposes.
Following are the features of a vacuum oven:
• It has a cooling system.
• It has shelves, carts and racks.
• It has timers, alarms, and recorder, logging options.
• It also has an explosion proof construction.
Advantages
of a Vacuum Oven
The working process of the vacuum oven is very interesting. It
contains an airtight vessel where the heating process takes place.
This allows the vacuum to be drawn inside the vessel. Therefore
the entire heat-treating process takes place in the vacuum or
under precisely controlled atmosphere. This heat-treating under
vacuum is advantageous for the following reasons:
• It prevents surface reactions like oxidation or decarburization.
• It removes surface contaminants like oxide films and residual
traces of lubricants.
• It removes dissolved contaminating substances from metals
by means of degassing.
Various
Forms of Vacuum Ovens
Vacuum oven comes in various forms. The configurations of vacuum
oven include bench or cabinet, tube or muffle and walk-in or truck-in.
The cabinet or bench ovens are suited for small batch equipments
that are mounted on integral stands. The tube or muffle oven is
an oven in which the heating occurs indirectly and the product
to be heated is placed in a refractory container, heated from
outside. The walk in or the truck in oven is suited for large
size batch equipments with double doors and integral carts and
shelves.
Types
of Vacuum Oven
Various types of vacuum ovens are available in market today. Following
are some of the significant types of vacuum ovens:
Multi
Module Vacuum Oven System - This type of vacuum oven
is ideal for product packaging applications that require vacuum
bake out. It also helps in laser welding, temperature curing and
inert gas seam sealing.
Squaroid
Vacuum Oven system - This type of vacuum oven can control
temperature up to 220°C. The built-in-high-limit thermostat
guards against overheating of the products. The oven is equipped
with vacuum fitting, which help in purging and venting of inert
gases and hydraulic thermostat, which controls temperature. This
oven is also required for heating, baking, sterilizing, brazing
and other purposes in the industries.
The vacuum
ovens, thus, serve multifarious facilities for the industries,
laboratories and scientific purposes. So install a vacuum oven
to get the maximum facilities in industrial and scientific matters.
