Continuous melting of damp brass swarf: Hans Bebber and Wilfried Spitz of Induga GmbH & Co KG, Cologne present concepts and practical results for melting damp swarf in a crucible-type furnace and report on initial experience gained in a fully operational plant

The recycling of brass swarf from the mechanical machining proces forms a traditional part of the melting programme in the foundry industry. While channel-type induction furnaces were predominantly used in the 70 to thaw such swarf, this changed at the beginning of the 80 The benefits of the coreless crucible induction furnace with its bath motion that can be varied via the specific power and oftenness and the resulting stirring consequence can be advantageously and systematically exploited here [1] to be paid to its greater profitability, the coreless-type furnace carne to replace the channel-type furnace for the recycling of swarf and ever-larger
