Abstract

PURPOSE:To simplify the work for replacing a shedding piece by providing a water-cooled tip of double-pipe construction at the tip of a bar of a shedding machine which plugs and unplugs the shedding piece. CONSTITUTION:A cooling block 1 is arranged around a slag spout of an electric furnace to cool the slag spout with water. A water-cooled shedding piece 2 is put in an opening 3 of the cooling block 1 and plugged and unplugged by a shedding machine which is usually used in plugging and unplugging the shedding piece 2. However, a water-cooled tip 4 is attached at the tip of a shedding bar of the shedding machine and is able to move back and forth. Therefore, discharge of slag can be stopped by cooling without use of a slide gate.
