How can casting foundry make products light weight, energy-saving
In order to carry out energy-saving and
should start from choosing raw materials, then we can save energy
consume, increase the use of source. During producing, we can
improve the gas discharge, purify the poisonous gas and control the
waste water discharge, so the dreams that saving materials, energy,
cost and the continual goal can be realized.
Arrange the structures of the products reasonably,
propel products light weight
Choosing the aluminum alloy as the raw materials of engine casting
to establish a clean casting foundry.
1. The aluminum has good mechanical property and it's density is
only 1/3 of the steel, but the property is 4.5 times of the iron.
Besides, the aluminum corrosion resistance and heat conduction is
very good. So the aluminum alloy has high intensity, recycle and
2. The pressure casting foundry of aluminum alloy can reduce
pollution, it is a clean casting foundry.
Recycle, increase the reuse of source, and
establish economical foundries
Increasing the use rate of source by increasing items produced,
increasing reuses of source by melting again, repairing the
defective casting and
reusing the waste sand, then establish the economical foundries.
Advocate using clean energy and new techniques,
1. Using high heat value clean energy when use melting furnace in
order to reduce poisonous gas discharge. From the economics
perspective, the natural gas is the best and the most reasonable
2. Using concentrated melting furnaces, utilize the discharged gas
which comes from the furnace to heat aluminum pig to increase energy
The advantages of using concentrated melting
a. The floor areas of concentrated melting furnaces are small and
the noise is low.
b. Because using the full-automatic control system, so the
caretakers are unnecessary and reduce the labor cost.
c. The firing system is very advanced; the gas discharge can reach
zero degree of ringelman blackness and can be exhausted by flue
