PURPOSE:To simplify the construction and to shorten the maintenance time by arranging the first supporting body to upward at the side part of supporting part of a ladle and the second supporting body to downard at the side face of the ladle, descending the ladle toward vertical direction as laying the ladle at the time of descending the ladle and executing auto-connection of piping, etc. CONSTITUTION:The ladle 4 is supported by hook A and descended to above the ladle supporting part 2 at an inclined angle theta, and then the first coupling body 3 arranged at the side part of the ladle supporting part 2 is started to contact as approaching the second coupling body 5 arranged at the side part of the ladle 4. And, the second guide body 23 is engaged as guiding with the first guide body 14, and the first supporting body 11 is abutted as inclining to the second guide body 21 by action of a supporting spring 8 and piston rod 10, and then the ladle 4 is laid on the ladle supporting part 2 at almost horizontal direction. And, after finishing the connection of the first coupling body 3 and the second coupling body 5, electric instruction and pressurized fluid are supplied and molten steel in the inside is discharged from opening hole arranged at the ladle 4 bottom.
