Title:
FURNACE COOLING DEVICE
Document Type and Number:
Japanese Patent JP3837119
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a furnace cooling device capable of improving ambient surroundings at a low facility cost, and not causing a burn even if a user touches its outside surface.
SOLUTION: This furnace cooling device is so structured that the circumferential surface of a rotating or rocking furnace 2 is cooled by two steps in the order of gas cooling by a cooling gas region 12 and liquid cooling by cooling liquid 13 not by directly cooling by the cooling liquid; and thereby the generation of steam around the furnace is prevented, and the furnace 2 is sufficiently cooled by preventing the leakage of the cooling liquid from the circumferential surface of the furnace 2 and by dispensing with rustproof measures for the circumferential surface of the furnace 2.
