vacuum pressure electric ovens | 真空電気炉

Outline | 概要

  This high-vacuum-pressure and high-temperature electric oven in a highly pure Ar atmosphere is designed to sinter and anneal a metallic or ceramics specimen. This oven is provided in its chamber with tungsten mesh heaters, reflectors and cooling layers. A turbo molecular pump, a vacuum pump and an operation panel are arranged to execute automatic operations of temperature raising, temperature holding and cooling.
 

Feature | 特徴

  By operating the gate valve and the cylinder mounted on the pass-box, a specimen can be put in and out through the pass-box. Accordingly, operations can be executed without the oven atmosphere injured, resulting in reduction in a period of time during which a high vacuum pressure is provided in the oven.
