The invention provides a Kaldo furnace lifting method and a lifting appliance thereof.The Kaldo furnace lifting method comprises the following steps that A, a Kaldo furnace is rotated so that a shaft core of the Kaldo furnace can be located in the vertical direction; b, the furnace cap and the furnace body are detached from the connecting flange; c, connecting a lifting lug arranged at the upper part of the furnace crown with a lifting hook through a sling, and then lifting and disassembling the furnace crown; d, the lifting hook is connected with the furnace body through a lifting appliance, and then the furnace body is lifted and detached. After split hoisting is adopted, the maximum hoisting capacity is only 39.575 t, and meanwhile, the hoisting space, namely the height of the furnace crown is increased by 1.195 m. A Kaldo furnace lifting appliance comprises a connecting plate in bolted connection with a flange plate, and the connecting plate is connected with the lifting appliance. Bolt connection is formed by the plate-shaped structure and the original bolt holes in the annular plate-shaped flange plate, so that connection is more stable, and meanwhile, the structure of the flange plate cannot be damaged.
本发明提供一种卡尔多炉吊装方法及其吊具,一种卡尔多炉吊装方法,包括以下步骤:A、旋转卡尔多炉使其轴芯位于竖直方向;B、将炉帽与炉体从连接法兰处拆分;C、将炉帽上部设置的吊耳通过吊索与吊钩相连,随后起吊拆卸炉帽;D、吊钩通过吊具与炉体连接,随后起吊拆卸炉体。采用分体吊装后,最大起重量仅39.575t,同时增大吊装空间即炉帽高度1.195m。一种卡尔多炉吊具,包括与法兰盘构成螺栓连接的连接板,连接板与吊具相连。通过板状结构与环形板状的法兰盘上原有的螺栓孔构成螺栓连接,使得连接更加稳固稳定,同时不会破坏法兰盘结构。
