<p>PURPOSE:To improve production efficiency by providing an insertion hole for the insertion of a new electrode, a base supported on the outside of a furnace wall, etc., and adding the new electrode to an energized electrode. CONSTITUTION:The electrode extension device is formed by the base 20, a support 30, an electrode holding cylinder 43, and a turning gear 50 for rotating the cylinder 43. The base 20 has an electrode insertion hole, and is supported on the outside of the vacuum furnace wall. In addition, the support 30 has an electrode insertion hole, and is elastically supported above the base 20. Moreover, the electrode holding cylinder 43 is rotatively provided on the support 30, and holds an electrode 110.</p> |
