Steel is particularly produced in two ways, the Basic Oxygen Furnace (BF/BOF) and the Electric Arc Furnace (EAF) - often applied to create new steel and recycle steel scrap.
According to World Steel Association, EAF contributes around 28% of global steel production in 2020. With the concern on carbon dioxide footprint and the increasing proportion of steel scrap yearly, many countries are on the journey to switch to EAF for steel production.
Are you an EAF-switcher who is interested in high productivity and ready to adopt an eco-friendly method in manufacturing? Read this blog to explore better solutions for your business.
Performance of Daiwa Calorized Lance
Daiwa Calorized Lance (CA Lance) is the calorizing coated steel pipe used not only for melting steel or refining steel by blowing oxygen gas, but also for the injection of carbon, lime, and/or other additives. Another usage is to remove slag inside oxygen converter, or other uses which require strong resistance against heat, oxidation, sulfuration, vanadium attack, etc.
We provide the Calorized layer and Ceramic coating both outside and inside of the pipe with the intention to make it stand for a much longer time than normal carbon steel pipe. And this is why Calorized Lance becomes a good option for oxygen or carbon injection in the steelmaking process.
Another interesting thing that we love to share with you is that our CA Lance can last 3 to 10 times longer than mild steel pipes depending on the conditions in which the lance is used. We did an experiment to see how our Calorized lance differs from normal Carbon steel pipe by testing both types under high heat at 3,000 Celsius degrees flame. The result shows that Carbon Steel pipe is melted down in 20 seconds. In the meantime, Calorized lance has a longer lifespan up to 151 seconds.
Size of Calorized Lance Pipe
In addition to above sample sizes, we can also make and serve special lengths such as 3/4" x 1.3M or 1-1/2" x 9.0M, as customer special requirements.
Which Type is Suitable for Your Business?
We are producing and supplying our lance pipes worldwide. Each customer requires different specifications of threads. Thread Type and Threadless Coupling are produced based on different purpose of simple, time-saving and reliable.
Are you still considering which type to choose among those?
・For Type 1,2,3: you can connect pipes together by hand quickly without the need of a connecting machine.
・For Type 4,5: the pipes will be welded together for better air leakage resistance. If you intend to purchase a small amount of pipe, it's highly recommended that you consider these two types. .
・For Type 6: The Threadless coupling that needs the Press machine to connect pipes. With higher volume for consumption, you can consider using this type due to its best air leakage resistance and easy connecting.
Please feel free to contact us, so we can share with you further advices to use the pipe effectively and safely. We can supply together with our CA Lance the Daiwa Press Machine for crimping purpose.
SDGs and Global Mission on Green Steel Production
Decarbonization is a requirement for all production on Earth, and we are committed to reducing carbon dioxide emissions from the steel production process by providing customers our CA Lance. Daiwa Lance is on a mission to protect the environment along with business development, following The Human Rights Guide to the Sustainable Development Goals (SDGs).
Our product can contribute reduce natural resources usage by reduction in number of pipes usage from end-users, following Goal No.12.2 of SDGs - “Achieve the sustainable management and efficient use of natural resources”.
In the meantime, CA Lance also can provide less time to connect pipe, this can contribute to reduce working time in front of EAF with lower chance of labor accidents, contributing into Goal No.3 of SDGs - “Ensure healthy lives and promote well-being for all at all ages”.
With the global mission, we know that many organizations are switching to develop the business with less carbon dioxide to protect human beings and livings on Earth. Let us go with you on the journey to build the better happy and clean world.
