What is Daiwa Calorized Lance Pipe?

Daiwa Calorized Lance Pipe (also known as oxygen blowing lance, oxygen blower, oxygen blowing lance, oxygen lance pipe, high temperature resistant lance pipe, or ceramic coated aluminum pipe) is a type of lance pipe mostly used to inject oxygen and carbon or other additives in the steelmaking process. In order to reach a high level of heat and oxidation resistance, Daiwa Calorized Lance Pipe will need to undergo a calorizing process.

What's the Technology for Making Daiwa Calorized Lance Pipes?

The technology used to produce Calorized Lance Pipe is called "Calorizing," or in other words, "aluminum diffusion." Calorizing is a surface modification process that diffuses aluminum into steel pipes both internally and externally. The purpose of the calorizing process is to protect the base metal from severe oxidation and corrosion caused by the high temperatures in the furnace or harsh environments. 

How is Daiwa Calorized Lance Pipe Manufactured?

To produce Daiwa Calorized Lance Pipes, a diffusion technology will be used. Mild steels will be heated to temperatures reaching 1,000°C, then aluminum penetrates the material, creating a durable aluminum-iron alloy (known as the calorized layer) that coats both the inner and outer surfaces of the mild steel.

Next, the product undergoes a ceramic coating process to enhance its heat and oxidation resistance when exposed to high-temperature environments.

What is Structure of Daiwa Calorized Lance Pipes?

Daiwa Calorized Lance Pipes typically consist of the following components:

  • Ceramic Coating (Inner Surface)
  • Calorized Layer (Inner Surface)
  • Mild Steel Core
  • Calorized Layer (Outer Surface)
  • Ceramic Coating (Outer Surface)
