Five methods of energy-saving production in Dongguan foundry

Dongguan foundry energy-saving production method

1. Save raw materials and recycle as much as possible. Because all the raw materials produced are consumed.

2. Improve management ability and reduce failure rate. For example, in a precision casting plant with an annual output of 5000t, every 1% reduction in unqualified castings is equivalent to the production of 50t precision castings. According to a ton of energy consumption of 405kgee, it can save 20t of standard coal a year, which means that one ton of precision castings can reduce the energy of 4kgee. Consumption.

3. Choose reliability design and upgrade processing technology to develop the honor of Dongguan precision casting processing technology. Under normal circumstances, under the premise of ensuring the quality of precision castings, by modifying the pouring system software and applying hot heat insulation gates, the export rate can be increased. If the export rate can be increased from 60% to 70%, it can be reduced by 14.3 % Of energy consumption.

4. Choose high compactness molding machine and modern core-making professional technology to reduce the quality of castings as much as possible and reduce the remaining amount of processing. Practical experience pressing design can make the quality of castings better than process modeling. General equipment modeling design can relieve 3%-5%, and the machining allowance can be maintained 2-3 mm. In the precision casting production workshop, it can not only reduce the net weight, but also reduce the energy consumption in the later production process.

5. Choose energy-saving production technology and effectively organize production. For example: Use self-setting resin sand or surface drying sand instead of clay sand to dry sand, reduce the energy consumption of air-dried castings, strictly seasoning, clarify the appropriate composition of precision cast steel, select reasonable design schemes, and remove the castings from the cast state. Ash or hard particles in order to cancel the graphitization annealing process; using as-cast ductile iron, the following elongation after breaking should be obtained in the as-cast state; as far as possible, use frequency harmonic oscillation aging processing technology to remove the heat of reducing ground stress Time-sensitive processing technology. Learning these will improve the efficiency of the company and save costs.
