The invention discloses a method for replacing a ladle turret rotary arm of a continuous casting machine, and belongs to the technical field of maintenance of ladle turrets of large-tonnage continuous casting machines. The method comprises the steps of mounting of fixed pieces, hoisting between two spans, horizontal movement, molten steel below-span hoisting, balance locking, hoisting landing, reassembling and the like. The ladle turret rotary arm of the continuous casting machine is moved to the position where a molten steel span crane main hoist can operate through a continuous casting crane main hoist and a molten steel span crane auxiliary hoist of existing facilities on site; a chain block is used for balance locking before molten steel span crane hoisting, and the situation that the rotary arm loses balance after the molten steel span crane auxiliary hoist is loosened is avoided; and after steel wire rope hanging of the molten steel span crane main hoist, balance locking of the chain block and stressing of the molten steel span crane main hoist, the molten steel span crane auxiliary hoist and the continuous casting crane main hoist are loosened, and then the molten steel span crane main hoist is used for hoisting landing. The aims of safely and effectively replacing the ladle turret rotary arm of the continuous casting machine, reducing the influence on production and improving maintenance efficiency are achieved.
