Abstract
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. Casting composition may then be inserted between the consumable form and the outer shell. The casting composition is heated for a period of time before the burden is ignited. Cables which are lowered from the top of the vessel and secured at a lower end of the vessel may be used. Tubes mounted on panels may be threaded along the cables to position the panels in constructing the consumable form.

A method of installing a refractory lining in a metallurgical vessel comprising:
- providing a metallurgical vessel including an outer shell;
- installing a consumable form along an inner surface of the outer shell, the consumable form is spaced apart from the inner surface of the outer shell;
- filling the metallurgical vessel with burden;
- supporting the consumable form with the burden;
- and
- inserting a casting composition between the consumable form and the outer shell to form the refractory lining.
A method of installing a refractory lining in a blast furnace comprising:
- providing a blast furnace including an outer shell;
- inserting an annular support plate against an inner surface of the blast furnace;
- securing a first elevation of panels to the plate, the panels spaced apart from an inner surface of the outer shell;
- securing a second elevation of panels to the first elevation of panels;
- filling the blast furnace with burden;
- supporting an inner surface of the panels with the burden;
- and
- pumping a casting composition between the panels and inner surface of the outer wall to form the refractory lining.
A method of installing a refractory lining in a blast furnace comprising:
- providing a blast furnace including an outer shell, and a plurality of tuyere openings formed through the outer shell;
- providing a plurality of panels, each panel including a tube attached thereto;
- inserting a steel cable into the blast furnace from a top portion of the blast furnace;
- lowering the cable to allow a lower end of the cable to be secured at the tuyere openings;
- inserting a top end of the cable through the tube on each panel;
- lowering each panel into a desired position along the cable;
- inserting a spacer rod through a grout opening of the blast furnace to space the panels from the outer shell;
- tightening the cable to remove slack and pulling the panels toward the outer shell;
- filling the blast furnace with burden;
- and
- inserting a casting composition between the panels and the outer shell to form the refractory lining.
