Abstract (en)
A method is provided for lining a blast furnace or other metallurgical vessel in stages using a plurality of porous consumable forms and a pumpable casting composition. A form member, including a rigid support frame and a porous consumable form mounted thereto, is installed in a lower portion of the vessel being lined, and is spaced from the vessel wall. Casting composition is then pumped into the space between the consumable form and the vessel wall, and is permitted to harden. Then, another form member is positioned above the first, and casting composition is pumped into the space between the second form member and the vessel wall. This process is repeated, using stacked form members, until the refractory lining is completely installed. <MATH>
