Reservoir nozzle for smelting furnaces has nozzle pipe inserted at side near top underneath supply pipe so that cavity underneath collects up foreign bodies to prevent clogging

摘要

The reservoir nozzle comprises a refined steel pipe (6) whose lower end (7) is pressed and welded (8) gas-tight. A supply pipe (1) is inserted at the top into the steel pipe and welded (2) gastight. The nozzle pipe (3) is inserted at the side near the top underneath the supply pipe and welded gastight (4). The cavity (5) formed underneath this nozzle pipe collects up the foreign bodies such as slag and sand from the supply pipe. The reservoir thus formed as a collecting area prevents clogging and blockages.
