The invention belongs to the field of steelmaking equipment, and particularly relates to a lining dismounting device for a vacuum furnace. The lining dismounting device comprises a furnace lining ejection mechanism and a furnace lining hoisting mechanism; the furnace lining ejection mechanism comprises a positioning steel frame, a connecting plate and a mounting seat cavity, and a jack is arrangedin the mounting seat cavity; the furnace lining hoisting mechanism comprises a main hoisting rod and at least three transverse hoisting claws evenly distributed on the main hoisting rod in the circumferential direction, the main hoisting rod is hinged to the transverse hoisting claws, the maximum included angle between the unfolded transverse hoisting claws and the main hoisting rod is 90 degrees, and the outer ends of the transverse hoisting claws are provided with claw ends extending outwards and upwards in an arc mode. According to the dismounting device, the furnace lining can be dismounted in the furnace within 8 hours or more after the furnace service is finished, an induction furnace does not need to be moved to another workshop for dismounting the furnace lining, the furnace shutdown time between the furnace service can be shortened after improvement, the production efficiency is improved, and the leakage detection and shutdown cost is reduced; and particularly, the dismounting time of the cold start boiler after a fault occurs can be greatly reduced.

    本发明属于炼钢设备领域,具体涉及一种真空炉炉内炉衬拆除装置,包括炉衬顶出机构和炉衬吊取机构;炉衬顶出机构包括定位钢架、连接板以及安装座腔,所述安装座腔内设有千斤顶;所述炉衬吊取机构包括主吊杆和至少三个沿周向均布于主吊杆上的若干横吊爪,所述主吊杆与所述横吊爪铰接,所述横吊爪展开与所述主吊杆之间的最大夹角为90度,所述横吊爪外端设有向外向上弧线延伸形成的爪端。本申请的这套拆除装置,可以在炉役结束后8小时以上就可以在炉内进行炉衬拆除,无需将感应炉移到另外的车间进行炉衬拆除,改善后可以降低炉役之间的停炉时间,提高生产效率、降低检漏及停机成本。特别是可以大大减少出现故障后产生冻炉的拆除时间。
