Abstract

PURPOSE: To accomplish formation of a thermal insulator for the furnace top for a short space of time through a dry solidification thereof after kneaded plastic by water and poured into a molding section.
CONSTITUTION: An inside frame piece is mounted on the upper portion of a coil arranged on the circumference of the crucible at the height of the top surface and a molding section in formed surrounded by a coil 1, an iron core 2, the inside frame piece 7 and an extended section 5A of outside furnace frame 5. A thermal insulator which is kneaded plastic is poured into the molding section and dried to be solidified to form a thermal insulator 6C for the furnace top. After curing, the inside frame piece 7 is removed. With such a method, a furnace top thermal insulator can be formed easily for a short space of time in the crucible type induction furnace.
