The flash furnace works with water-cooled elements that protect its structure from the heat of the process. LTF fabricated and installed the circuits that feed those elements: dozens of copper lines, each with its own valve, connected to 316L stainless steel supply manifolds.
The circuit joints were made by silver brazing, and the 6, 8 and 10 inch supply systems were fabricated and installed in 316L stainless steel. Installation was completed with the furnace supply hoses, with a workforce of 200 on rotating shifts.

- 01
Fabrication and installation of the Flash Furnace cooling circuits
The furnace works with water-cooled elements that protect its structure from the heat of the process. The circuits that feed them are dozens of copper lines, each with its own valve.
- 02
Silver brazing of the cooling system
The joints of the copper lines in the circuits were made by silver brazing.
- 03
Fabrication and installation of 316L steel supply manifolds
The 316L stainless steel manifolds distribute the water to the circuits: each copper line connects to them through its own valve.
- 04
Fabrication and installation of 6, 8 and 10 inch supply systems in 316L stainless steel
The 6, 8 and 10 inch supply lines were fabricated and installed in the same 316L stainless steel as the manifolds.
- 05
Installation of the Flash Furnace supply hoses
The furnace supply hoses completed the installation of the system.
- 06
Workforce of 200 on rotating shifts
The work took place in the Flash Furnace building, the heart of the Chuquicamata smelter, with 200 people on rotating shifts.

Site context
The Flash Furnace is the heart of the Chuquicamata smelter, Codelco’s largest: around the middle of the last decade it had a smelting capacity of 1.4 million tonnes per year, with one flash furnace, two Teniente converters and three Peirce-Smith converters. Its cooling systems keep the elements surrounding the molten bath within their temperature range.
