Calorized Lance Pipe

A calorized lance pipe is a type of lance pipe used in steelmaking processes, such as in electric arc furnaces (EAF), to inject oxygen and carbon. The pipe has a special calorized treatment applied to it.

The calorizing process involves diffusing aluminum onto the surface of the lance pipe and heating it to 1,000°C. This forms a heat-resistant aluminum-iron alloy, known as the calorized layer. When exposed to high temperatures, the surface of this layer forms a durable aluminum oxide (alumina) film, which suppresses the severe oxidation of the lance pipe itself.

Calorized lance pipes contribute to a longer service life, cost savings, and safer operations in electric furnace steelmaking.

These pipes are manufactured by one of our group companies, Daiwa Lance International (DLI). Discover how our calorized lance pipes, or Daiwa CA Lance, can improve your steelmaking process.
