OXYGEN LANCING TUBE (PIPE)
[CODE NO. 3240]
Oxygen is used in the manufacture of metals like steel, copper and zinc. Chlorine is used in the manufacture of Aluminum. These gases react with the undesirable impurities and form their respective oxide or chlorides. These oxides or chlorides then float to the surface of the molten metal and are removed.
To transfer these gases to the molten metal, a pipe is needed. This pipe is the lancing pipe and the process of injecting gases into molten metal is known as lancing.
Traditionally an ordinary pipe has been used. The material of construction is low carbon steel (Mild Steel), electrically resistance welded (ERW) in the shape of a pipe. Since the molten is steel or copper or zinc, and the pipe is of mild steel, the pipe melts into molten metal, at the end which is dipped into it. Besides because of high temperature of the molten metal, the pipe also gets oxidized and melts faster into the molten metal. Hence the pipe gets consumed and has to be replaced.
Generally large furnaces are non Tilting in Type and use bottom pouring method to take out the Molten Metal through the Tap Hole. When the Tap hole needs to be opened the same is done with the help of a High Frequency Induction Welded Low Carbon Mild Steel Tube which can sustain 750 PSI Pressure without leaking of Suitable Size 8mm NB,15mm NB or even 25mm NB in certain Cases. Oxygen at high pressure is injected through these tubes into the Tap Hole and the molten metal starts flowing. Depending on the type of Ferro alloy or Steel Plant or Copper or Zinc Smelter the Consumption of the Pipe is determined. These lancing pipes are basically used to open the Tap holes of Bottom Pouring Furnaces.
