Beschreibung
Zusammenfassung:	Provided is a bearing box for a rotating roll that delivers a high-temperature substance, the bearing box being capable of reducing a thermal load at a bearing portion and a seal portion provided adjacent to the bearing portion to effectively prevent rotation failure, breakage of the bearing portion, and hardening of the seal portion.The bearing box 1 for a rotating roll that delivers a high-temperature substance according to the present invention includes the bearing portion 3 and the seal portion 5 provided adjacent to the bearing portion 3 and includes: a first cooling liquid passage 7 that is formed on the outer peripheral side of the bearing portion 3 and through which a cooling liquid passes; and a second cooling liquid passage 9 that is formed on the radially inner side relative to the first cooling liquid passage 7 and on the outer peripheral side of the seal portion 5, the second cooling liquid passage 9 communicating with the first cooling liquid passage 7 to cause the cooling liquid to pass therethrough.
