PURPOSE: A wall structure of a ladle is provided to remove a gap by forming a filling layer in a ladle wall unit, thereby reducing a joint opening phenomenon of ladle refractory materials by improving the structural stability of the ladle. CONSTITUTION: A wall structure of a ladle comprises a steel case(102), a wall unit(120), and a filling layer(130). The steel case of an opened shape with an opened top is extended so that a lateral wall becomes wide in a radial direction from the bottom to the top of the lateral wall. The wall unit formed in the inner surface of the steel case includes bricks(128) of a multiple layer. The filing layer formed between the wall unit and the bricks reduces a joint opening phenomenon. The filling layer is preheated at a temperature of 600°C or greater after filling powdered magnesia filler, thereby becoming solidified.
