Integration of plasma treatment casting for energy savings in cast iron foundries
It was the goal of this project to investigate the extent that it is possible to optimize the design of feeders for cast iron and to examine whether by optimizing the estate's design also can achieve substantial savings. The project has aimed both to improve existing methods and finding new ways to improve the use of feeders.
Project description
During a ph.d-study a further development of plasma treatment casting technology (PTC) in cast iron foundries and by optimising the machines feeding with a specialdesigned electric arc welder savings are achieved for energy, sand and iron and produces a final product with improved mechanical properties.
Results
Casting of metals is one of the shortest paths to provide the form for complex geometries. On a daily basis we encounter molded parts in cars, trains, computers, furniture, windmills and numerous other structures that affect our everyday lives.In Denmark produced annually about 80,000 tons of cast iron exported to the world. Vald. Birn group, which also includes foundries abroad, producing together 200,000 tonnes. Foundry industry is among the most energy-intensive companies we have. This is also one of the industries where we have the greatest degree of recycling. Worldwide reused about 80% of iron and steel for the production of castings and steel structures. It is only the paper industry, which has a correspondingly high recycling.
An earlier research project (PSO 336-007) have shown that there is great potential for saving energy by optimizing the design of feeders for castings.
