PURPOSE:To simplify a process of executing refractory, to improve executing efficiency and to reduce necessary labors by setting a core at inside of a molten metal vessel and executing a lining by charging monolithic refractories into a space formed between inner wall-face of the above-mentioned vessel and outside wall-face of the core. CONSTITUTION:After finishing a permanent lining brick laying for ladle bottom part 7 and inner wall part 8, slag-line bricks 5 are laid. The slag-line bricks 5 are laid above the permanent lining bricks 8 and along the inner side faces of the permanent lining bricks 9 at the slag-line part as projecting toward the ladle 1 center direction from the bricks 8 as cantilever-like. Next, the core 3 having truncated cone-like at its top part is set at center of the ladle 1 and the monolithic refractories 4 charged into the space 4 are formed as ladle lining, while vibrating and floating air bubbles. Timings of the solid refractory laying work and the monolithic refractory laying work are executed surely as separately.
