High Heat-Resistant Oxygen Lance Pipes in Furnaces

Daiwa Calorized Lance Pipe (Daiwa CA Lance) is a heat-resistant lance pipe that undergoes a thorough calorizing metal surface modification, in addition to being coated with a protective ceramic coating layer inside out. Thanks to this process, the lifespan, heat resistance, and minimum consumption of Daiwa CA Lance are all significantly enhanced.
Using the latest technology of calorizing, Daiwa CA Lance possesses the power to deliver up to 7x super strength for blowing and injecting oxygen into liquid or molten steels.

*Note: Dual protective layers of calorized and ceramic coating can be flexibly applied with different thickness to suit changing needs of each customer.

1. Blow oxygen to cut steel scraps or refine molten steels in Electric Arc Furnace (EAF).
2. Blow carbon, lime powder and/or other additives for adjusting grades of carbon steels.
3. Cut and melt to remove the residual slags adhered inside the oxygen converter.
4. Blow inert gases such as nitrogen, argon into the ladle furnace or smelters.
5. Protect dipping thermocouples against the high temperature of molten liquids in aluminum, copper, and zinc melting furnaces.
6. Other uses that require strong resistance against heat, oxidation, sulfuration, and vanadium attack.
