What is the long-term benefit of adopting Calorized Lance Pipe in the production line?


Depending on the application and usage goals, notably for oxygen lancing, end users of lance pipes have additional alternatives for employing steel pipes to increase efficiency. The challenge is that customers cannot imagine how much they can improve their productivity in the long term, and which option would be suitable to choose for various purposes. Today, we'll give you an overview of the three primary steel pipe types that are employed in the steel melting and refining process: mild steel pipe, ceramic-coated pipe, and calorized pipe.

Definition of Daiwa  Lance Pipes - SC, CC, CA

Mild steel (MS) pipes are made of steel with a low carbon content (less than 0.25 %). The pipes do not harden and are easy to use because of their low carbon content. MS Pipes are readily welded and molded into various forms and sizes for pipelining and tubing applications since they are constructed of mild steel. This kind is commonly applied in a variety of industrial and engineering applications, as well as for lancing purposes in steel manufacturing.

Ceramic Coated Lance Pipes (CC Lance Pipe) is manufactured by applying a special refractory coating on the inside and outside of mild steel pipe. Depending upon the normal bore of the pipe refractory coats are applied both inside and outside of the pipe. This improves the resistance of the Ceramic Coated Pipes to the attack of liquid metal and slag. It is used in Electric Arc Furnace for oxygen, and other gas blowing. The Coating Layers are provided in more than 1-time coating layer, depending on each customer's requirement. Compared to Calorized Lance pipe, Ceramic Coated Lance pipe is easier to burn during usage.
Ceramic Coated Lance Pipe
DAIWA CA LANCE (CA Lance pipe) is produced by our know-how of Calorizing process technology. During the production, Calorized layer and Ceramic coating are provided both for the outside and inside of the pipe. Our calorizing process lets CA Lance pipe stand for a much longer time than normal Mild steel pipe. It is used for oxygen/carbon injection for steel making. The calorized layer and the refractory coating layer together generate strong heat resistance and anti-oxidation to achieve minimum consumption of lance pipe to cut down your cost.

Daiwa Lance's Recommendation

End users have a variety of alternatives for using steel pipes to improve performance, depending on each application and usage purpose. Daiwa Lance has its own calorizing technique for steel melting and manufacturing that can produce both calorized and ceramic-coated pipe with the goal of making it last a lot longer than mild steel pipe. Calorized Lance is a suitable substitute for oxygen or carbon injection in the steelmaking process as a result.

For the purpose of construction, or for use without the high requirements of long time heat resistance,  Daiwa SC Lance pipe is our recommendation. On the flip side, with a medium range of corrosion and heat resistance, the Daiwa CC Lance pipe will be one of the alternatives for you to choose. The best option of our recommendation is Daiwa CA Lance pipe as our Know-How to expand the performance for steel production.
