VACUUM ARC MELTING APPARATUS FOR EASY-TO-THE SPECIMEN OBSERVATION AND FOR THE CONVENIENT ELECTRODE MOVEMENT

摘要

The present invention relates to a vacuum arc melting apparatus capable of easily observing a specimen and conveniently moving an electrode in a material melting process in a melting chamber. In the vacuum arc melting apparatus, a vacuum chamber includes a chamber body which comprises a sidewall and is made of transparent materials for visible rays. An electrode rod manipulating unit is formed in the chamber body to control the location of an electrode rod. Thereby, a worker can manufacture an ingot specimen with high quality through uniform alloy melting by conveniently observing the specimen and controlling the location of the electrode rod.
