Title:
HEARTH CARRIAGE CONNECTION STRUCTURE FOR ROTARY HEARTH FURNACE
Document Type and Number:
WIPO Patent Application WO/2007/113929
Kind Code:
A1
Abstract:
In a rotary hearth furnace comprising a plurality of hearth carriages, each of the hearth carriages on which a hearth is placed has a running device. The hearth carriages adjacent to each other are connected to each other through a spacer by bolts and nuts at an interval in one row on a horizontal plane. Even if respective hearth carriages are thermally deformed during the operation, the hearth carriages can be freely deformed without being restrained each other by curved deformation, and therefore, the hearth carriages are always kept in a stable state.
