Title:
ROTARY HEARTH FURNACE
Document Type and Number:
WIPO Patent Application WO/2014/167916
Kind Code:
A1
Abstract:
Provided is a rotary hearth furnace equipped with an eccentric rotation suppression function, with which eccentric rotation of the hearth can be suppressed appropriately during startup and low-temperature operation as well as during high-temperature operation, even when the hearth is large and when the circumferential rotational velocity is increased, and which is compact and has a simple configuration, enabling the installation space and the manufacturing cost to be reduced. This rotary hearth furnace is equipped with: an annular hearth (4) rotationally driven in the horizontal plane on an installation base (2); a ring body (11) provided under the hearth and concentric with the annular hearth; multiple lever arms (12) arranged at equal intervals in a circular fashion on the installation base and having pressure-receiving rollers (16) which are pressed by the ring body in response to displacement of the hearth within the horizontal plane; and spring units (17) which are provided on the installation base, and bias the lever arms so as to push back against the ring body in response to the pressing of the pressure-receiving rollers of the lever arms.
