The six methods of precision casting energy saving production

H2. As we all know, at ordinary times in the casting, accidentally will produce the die. The formation of scrap not only delays the staff's time, but also wastes the material of the module. But now advocate of saving energy production in China, under the influence of national policy, now many of the precision foundry industry structure change on the energy conservation and environmental protection, the energy saving in the precision casting production what are the considerations, the following conclusion: a total of six

H3. 1. Improve the production rate of precision casting parts by optimizing design and optimization process. On the premise of guarantee the quality of precision castings, change the gating system, using heat insulating riser can often increase exports, if we can increase the export rate from 60% to 60%, can reduce energy consumption by 14.3%.

H4. 2. Adopt high compactness molding machine and modern core technology to minimize casting quality and reduce machining allowance. It is proved that the high pressure molding can reduce the casting quality by 3-5%, and the machining allowance can be kept at 2-3mm. Reducing weight not only makes the precision casting shop energy efficient, but also reduces the energy consumption of the subsequent processing.

H5. 3. Adopt energy-saving technological process and rationally organize production. For example: use self-hardening resin sand or surface dry type to replace clay sand drying, saving the energy consumption of baking mold; To eliminate the graphitization annealing process by eliminating the white or hard points on the castings in the casting state by strictly applying the ingredients, determining the appropriate components of precision castings and taking effective inoculation schemes. To promote the cast iron, it is required that the elongation under 12% should be obtained under the casting condition. It is possible to use frequency wave harmonic vibration aging process to remove the thermal aging process.

4. Save materials and try to reuse them. Because the production of any material needs energy.

5. Precision casting enterprise scale production, i.e., the output of each casting unit is above 5000t. Because of the large output of the enterprise, the working time of the furnace is long, and the heating energy of the furnace itself is amortized to the energy consumption per ton of precision castings.
