Title: Method for operating copper smelting furnace
Inventor: TAKAHASHI MASAHARU
IPC: F27D3/14
Filed: 2001-11-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a simple and safe method for coping with such a difficulty that a tapping operation for a tapping matte or slag is very dangerous if condensed dew exists on the surface of a water-cooled flume, because when the tapped matte or slag covers the surface of the dew, a phreatic explosion occurs and the molten body bursts.  <P>SOLUTION: This method for operating a copper smelting furnace comprises, in a smelting process for copper, discharging matte or slag from a hold, finishing tapping by plugging a hole of an outlet portion, removing stuck copper remaining on the water-cooled flume, applying oil onto the surface of the water- cooled flume to form a heat insulating layer between the water-cooled flume and air, and thus preventing dew formation and hence the phreatic explosion when the molten body flows again after the operation.  <P>COPYRIGHT: (C)2003,JPO
