Learn Why Copper Furnaces are the Best Choice to Melt Copper

Before The Induction Copper Furnace. Prior to the introduction of copper furnaces in the 20th century, those who worked in the copper melting industry used fuel-based furnaces. Not only was this a costly process, but the furnaces also emitted large volumes of pollutants into the air which had a negative impact on both the environment and anyone working anywhere near the furnaces.

Bright Annealing Copper and its Alloys - Industrial Heating

The basic function of the furnace atmosphere in copper-based-alloy annealing is to protect the product from oxidation. To achieve this, the oxygen partial pressure of the atmosphere must be less than that necessary to form the oxide. Even high-purity nitrogen contains one or two parts per million of oxygen, and furnace leaks are inevitable.

60 Centuries of Copper: Early Smelting Practice

Long afterwards smelting furnaces acquired the shape that they essentially maintained right down to Victorian Swansea days, i.e. a small stone or brick chamber with some means of pouring or ladling out the molten metal, a hearth below, and a brick chimney, usually low and stumpy, which provided an updraft and allowed the waste gases to escape.
