Abstract
Official abstract text for this publication.
A bearing box for a rotating roller for supporting or transporting a high-temperature object. The bearing box includes a bearing and seal units disposed therein. A cooling jacket is disposed at an outer periphery of the bearing box so that the cooling jacket covers at least a portion of an axial region of the bearing and at least a portion of an axial region of the seal unit. The cooling jacket has a cooling water inlet and a cooling water outlet, and the bearing box is cooled by cooling water supplied to the cooling jacket through the cooling water inlet.
First claim
Opening claim text (preview).
The invention claimed is: 1. A bearing box for a rotating roller for supporting or transporting a high-temperature object, the bearing box comprising: a bearing and a seal unit disposed therein; and a cooling jacket having a cooling water inlet and a cooling water outlet, the cooling jacket being disposed at an outer periphery of the bearing box so that the cooling jacket covers at least a portion of an axial region of the bearing and at least a portion of an axial region of the seal unit, wherein the bearing box is cooled by cooling water supplied to the cooling jacket through the cooling water inlet, and wherein a portion of an outer periphery of the cooling jacket disposed at an outer periphery of the axial region of the seal unit is at least partially disposed on a radially inner side of a portion of an outer periphery of the cooling jacket disposed at an outer periphery of the axial region of the bearing. 2. A steel continuous casting machine, wherein a cast slab is supported or guided by one or more rotating rollers, each of which is supported by a bearing disposed in a bearing box according to claim 1 . 3. A steel continuous casting method comprising continuously casting a steel slab by using a steel continuous casting machine according to claim 2 . 4. A method for cooling a bearing box for a rotating roller for supporting or transporting a high-temperature object, the bearing box comprising a bearing and a seal unit disposed therein, the method comprising: placing a cooling jacket at an outer periphery of the bearing box so that the cooling jacket covers at least a portion of an axial region of the bearing and at least a portion of an axial region of the seal unit; cooling the bearing box by introducing cooling water into the cooling jacket through a cooling water inlet provided in the cooling jacket; and discharging the cooling water that has cooled the bearing box through a cooling water outlet provided in the cooling jacket, wherein a portion of an outer periphery of the cooling jacket disposed at an outer periphery of the axial region of the seal unit is at least partially disposed on a radially inner side of a portion of an outer periphery of the cooling jacket disposed at an outer periphery of the axial region of the bearing.
