A method is provided for installing a refractory lining in a blast furnace or other metallurgical vessel. A consumable form is installed along an inner surface of an outer shell of the metallurgical vessel. The consumable form is spaced apart from the outer shell. The metallurgical vessel is then filled with burden, which supports the consumable form.
