Boyne Smelters Limited (BSL) had a big moment on Friday when it officially opened its new, much-anticipated Carbon Bake Furnace 4 (CBF4).
The development is part of a $720 million upgrade at the plant, launched in 2008 and designed to improve productivity and environmental performance.
A carbon bake furnace is basically a super-sized oven that bakes blocks, called 'anodes', which are required in the aluminium production process.
The new furnace will typically produce 2500 carbon anodes per week, while burning less natural gas that the original Carbon Bake furnaces 1 and 2.
The 1.2 tonne anodes are loaded into the furnace by crane and heated at temperatures over 1200 degrees Celsius.
The heating and baking process takes about 18 days, after which time the blocks are removed from the bake and transported to the reduction cells for use as electricity conductors to make aluminium.
