To put this in perspective, the results of a carefully documented study of an aluminum holding furnace
with an old lining vs.
Other projects in the pipeline for the Smelter includes the installment of an electric holding furnace
to temporarily store and upgrade copper matte until it can be transferred to a converter furnace for final processing.
This liquid metal is held at about 700degC in a holding furnace
before it is transferred to a ladle and poured into a casting mould.
Some 15 tonnes of molten iron spilled from the holding furnace
into the cooling tank beneath the furnace, but no one was injured or hurt in the accident, the company said.
These include "metal delivered ready to cast, no melt loss compared to melting of ingots, consistent quality, lower emissions in the foundry, the transportation crucible can be used as holding furnace
via new heating system, no maintenance cost for foundry for holding furnace
, very little space required, no ingot inventory and therefore less financing cost, no future investment in melting and holding furnaces
Dore produced can be cast directly into anodes eliminating the holding furnace
The holding furnace
for the molten metal is located beneath the fixed plate.
Plus it will increase the capability of the Ausmelt so eventually it can become our only smelting furnace and allow us to convert the old reverberatory furnace, which is responsible for most roof level emissions, into a holding furnace
can serve as a melting furnace, but lacks sufficient capacity to support both block and head lines indefinitely at full production rates.
After the final copper-making blow, the blister copper is transferred to a holding furnace
or directly to a refining furnace.
Tenders are invited for full lining of melting and holding furnace
