Abstract
Disclosed herein is a metallurgical furnace and roof for the same. The roof has a body. The body has a top surface having a center. The top surface has a center opening disposed about the center. The body has a bottom surface opposite the top surface. An outer sidewall connects the top surface to the bottom surface. The outer sidewall, bottom surface and top surface define an interior portion, wherein the outer sidewall has a lift side and a hood side. An internal spray cooling system is disposed in the interior portion of the body. Lift brackets are disposed on the top surface. The lift brackets are configured to support the entire weight of the roof when suspended by a crane, wherein all the lift brackets are disposed in a first segment of the roof.

A roof for a metallurgical furnace comprising:
- a body comprising:
- a top surface having a center, the top surface having a center opening disposed about the center;
- a bottom surface opposite the top surface;
- and
- an outer sidewall connecting the top surface to the bottom surface, the outer sidewall, the bottom surface and the top surface defining an interior portion, wherein the outer sidewall has a lift side and a hood side;
- an internal spray cooling system disposed in the interior portion of the body;
- lift brackets disposed on the top surface, the lift brackets configured to support a weight of the entire roof when the roof is suspended by a crane, wherein all the lift brackets are disposed in a first segment of the roof.
A metallurgical furnace comprising:
- a tilt platform;
- a gantry crane attached to the tilt platform, the gantry crane having arms;
- a furnace body disposed on the tilt platform, the furnace body comprising:
- a sidewall, the sidewall having a top disposed opposite a bottom, wherein the sidewall surrounds an interior portion of the furnace body;
- a roof disposed on the top of the sidewall, the roof comprising:
- a roof body comprising:
- a top surface having a center, the top surface having a center opening disposed about the center;
- a bottom surface opposite the top surface;
- and
- an outer sidewall connecting the top surface to the bottom surface, the outer sidewall, the bottom surface and the top surface defining an interior portion, the interior portion configured to be cooled with a spray cooling system, and wherein the outer sidewall has a lift side and a hood side;
- and
- lift brackets disposed on the top surface, the lift brackets coupled to the arms of the gantry crane and configured to support a weight of the entire roof when the roof is suspended by the gantry crane, wherein all the lift brackets are disposed in a first segment of the roof.
A method of moving a roof from a metallurgical furnace, comprising:
- attaching a gantry crane to lift points disposed on a first half of the roof closest the gantry crane;
- and
- lifting the roof with the crane by the two lift points wherein the weight of the roof causes a moment about the lift points and directs the roof to contact the gantry crane.
