実験室用真空アーク溶解炉の試作

真空および雰囲気中アーク溶解法の研究-I

抄録

An arc furnace for melting non-refractory and refractory metals and alloys in vacuum or an inert atmosphere was described.
The furnace was designed by the authors with an emphasis placed on adaptability to diverse requirements of research, and can be used for arc melting with either a consumable or a non-consumable electrode. Besides, the specially designed sliding crusible gives prospect of preparing electroderods for the use of consumable melting.
Refractory metals, such as Ti, Cr and Mo as well as steels were successively arc-melted with the aid of this furnace.
The melting variables, such as arc current, voltage and stability as well as ingot quality and degassing were discussed based on the melting experience of various steels.
