Energy saving technology and measures of foundry industry

As a major energy consumption of mechanical industry, foundry industry has the features of high energy consumption, low resource utilization, heavy pollution, poor economic performance, and it has restricted the development of foundry industry. Rationally using sources, grasping energy saving technology vigorously is an important mission and developing trend of foundry industry.

Energy saving technology and measures are as follows:

1.Recycle and reuse of used sand: the developed countries such as United States

and Europe, have been the recycling of used sand as a major research topic. And this technology has been put into industrial production.

2.Recycling of binder: environment - friendly inorganic binder with sand core and sand treatment and recycling technology obtained more and more attention.

3.Regeneration of mold and pattern material: Since the 1990s, Europe and the United States treat the waste pattern material or recycled pattern material from casting manufacturer with special cleaning measures, then adjust the composition according to users’ requirements, forming the ‘recycling-regenerative pattern materials’.The key to this technology is adopting the advanced multi-stage filtration or centrifugation, speeding the operation process to obtain the purer pattern materials.

4.Centered on melting energy - saving technology: Energy consumption of mold melting accounts for 50% of total production energy consumption. Casting scrap caused by melting accounts for 50% of the total scrap. Therefore, the use of the new melting equipment and melting process are main measures of energy saving.
