high-frequency induction heating device | 高周波誘導加熱装置

Outline | 概要

  The high frequency induction heating system MU-1700 series is made compact in a personal-computer size into which a conventional large-sized and expensive heating system is being transformed. This space-saving and highly functional system MU-1700 is to be used for study of physical properties, study of semiconductors, and sample preparation.
 

Feature | 特徴

  When there is used a crucible made of a material having a high melting point such as carbon, tungsten, or molybdenum, operations can be executed at the maximum service temperature of about 2200ºC.

Specs | 仕様

Rapid heating
 
When a metallic specimen, for example 30g of a Co-Cr alloy, is directly heated, it can be heated to 1400ºC (melting point) in about 20 seconds.  
Rapid cooling  
The crucible and the oven core tube made of inorganic materials are not heated, resulting in rapid cooling.  
When the oven core tube is made of quartz, the inside can be observed.  
When a carbon crucible is used, a specimen of an inorganic material can be heated indirectly.  
Only necessary portions can be heated.  
For a specimen which is a ceramics/plastic-metal complex, only the metal portion can be heated.  
Simple structure, facilitating the maintenance.  
As an example of application, this heating device can be incorporated in a glove box in which a specimen can be heated, molten and calcined in inert gas.  
       
 
 
       
 
Study of Semiconductors
Heating of a specimen vacuum encapsulated in a quartz tube
Heating of Fluid
Heating of a liquid, powder or gas by disposing a heat generating member (carbon honeycomb, metallic ring or the like) in the fluid passage.
 
  Encapsulation of Electrodes
A glass specimen is locally heated,molten,and welded to the electrode such that the inside gas is encapsulated.
Hardening and Annealing
Heating of a specimen, for example a SUS round rod of 20φ, to 600ºC in about 30 seconds.
 
  Direct Heating
Direct heating of a metallic specimen One of a variety of crucibles is to be selected according to heat resistance and reactivity.
Evacuation (Gas Exchange)
With the use of an evacuation/gas exchange unit (optional), the atmosphere of only the periphery of a specimen can be controlled.
 
  Indirect Heating
Heating and melting of a specimen, such as pure silicon, glass, ash, which does not directly generate heat by high-frequency induction.
In a Vacuum/PressurizingContaine
Study of battery materials or preparation of an alloy of metals of which melting points and boiling points are different from one another.
