CALORIZED LANCE PIPE

Calorized lance pipe is made up of 5 layers. At the core is a high quality mild steel lance pipe. In the calorization process the lance pipe is heated to 1000c (1830f) in a mixture of aluminum powder. At 1000c (1830f), the aluminum fuses with the surface of the steel pipe and forms a permanent layer of aluminum-iron alloy. The Calorized pipe is then coated inside and outside with a layer of refractory material which resist heat and slows the melting of the lance pipe. When Calorized pipe is exposed to high heat the refractory material and the Calorized layer form an Aluminum Oxide Film which increases the melting temperature to 2050 degrees c (3750 degrees f). Bare lance pipe melts at temperatures of 1300 to 1500c (2400 to 2800 f.)

The calorization process differs greatly from ceramic coating. The ceramic coated process is similar to a layer of paint which is baked on but does not fuse with the lance pipe. Ceramic coating is simply a coating whereas the calorization process is a fusion process where the calorized layer becomes part of the steel pipe.

 Calorized lance pipe is used for melting and refining steel by both injecting oxygen and injecting other elements such as Carbon or Lime into the melt.

USES

• Cutting steel scrap and refining steel.
• Injection of carbon, lime powder and or other additives for adjusting grades of carbon steel or specialty steels.
• Removing slag inside oxygen convertors.

Calorized lance pipe is available in standard pipe sizes with 3 different end finishes.
