Title:
CYLINDRICAL FAR INFRARED HEATER
Document Type and Number:
Japanese Patent JP3118340
Kind Code:
B2
Abstract:
PURPOSE: To uniformly heat a plurality of thread- or wire-like products simultaneously and enhance thermal efficiency by partitioning the inside of a ceramic cylinder into a plurality of heating chambers via a ceramics partition plate.
CONSTITUTION: The inside of a ceramic cylinder 1 where a coil-like resistant heating band 2 is spirally embedded along the outer peripheral surface is partitioned into a plurality of heating chambers 6 via a ceramic partition plate 5. Thread-or wire-like products simultaneously pass into the heating chambers, followed by a heat treatment. Since each heating chamber 6 exposes to a far infrared radiated surface formed on the inner circumferential surface of the ceramic cylinder 1, it can be uniformly heated under the same condition, to thus eliminate a variation of a quality of products in each heating chamber. The ceramic partition plate 5 can prevent contact between the products due to shift of the products even at a high processing speed. Furthermore, it is possible to prevent any adverse effect on other products even if an accident of breakage of any product occurs.
