How to Realize Green Casting Foundry in China
China is No.1 in casting production in the
world. But its productive level is quite low. There are many small
factories with high energy consumption in China’s foundry industry.
Compared with the developed countries, the environmental investment
in China is far from enough. To achieve green casting, we have heavy
responsibilities and also a great potential, and we believe we are
able to make China change from a big casting country into a casting
power in the near future.
The implementation of green energy conservation and environmental
protection is the key to achieving sustainable development.
Therefore, we must research and promote energy-saving, environmental
protection new technology and new equipment which are suitable for
China's actual conditions.
1. To focus on melting and heating system, and tap the comprehensive
energy-saving potential. Adopt all kinds of new technology to
eliminate pollution to the environment, and improve the melting
quality, reducing defective index.
2. To save material resources, and develop material recycling
technologies to reuse foundry waste and create the highest value of
reuse. For example, use new technology of recycling old sand.
3. It is estimated that China's foundry industry accounted for the
total annual energy consumption 25% to 30% of the machinery
industry, and the pollutant emissions per unit of production are
much higher than developed countries.
Therefore, we should solve environmental pollution problems from the
materials, processes and equipment aspects. Develop non-toxic
refining and metamorphic technique, and non-toxic tasteless white
binder and casting materials, dust removal, sand regeneration, and
no dust casting technology.
4. To strengthen the mechanization and automation of production
processes, improve labor productivity, and to achieve nearly no
margin of casting production technology.
To achieve green casting, every foundry is responsible and they
should do certain contributions, only by the collective work, can we
achieve green castings in the near future.
