What are the common problems of alloy steel precision casting?

Everyone knows, usually inAlloy steel precision castingAt this time, it is very likely to cause damage to the module unintentionally. The occurrence of damage not only delays the staff's time, but also consumes the raw materials of the module. Nowadays, energy-saving production is advocated in our country. Facing the influence of new national policies, many precision casting manufacturers will change their industrial layout to energy-saving and environmental protection. ThenAlloy steel precision castingWhat are the common problems in energy-saving production in China? I have summarized the following aspects:

1. Adopting reliability design and improving processing technology to improve the production rate of precision castings processing technology. Under the prerequisite of ensuring the quality of high-precision castings, changing the gating system and applying hot thermal insulation risers can generally increase the export rate.

2. Adopt high compactness molding machine and its contemporary core-making technology to minimize the quality of castings and reduce the remaining amount of processing. It has been proved that high pressure molding can reduce the quality of castings by 3%-5% compared with manual molding and general equipment molding, and the remaining amount of processing can also be maintained at 2-3 mm. Reducing the net weight not only makesAlloy steel precision castingEnergy saving in the production workshop can also reduce the energy consumption of subsequent production and processing.

3. Adopt energy-saving production process to effectively organize production. Promote as-cast ductile iron, and stipulate that the elongation after fracture is below 12% should be obtained in the as-cast state; as far as possible, use the frequency wave harmonic vibration aging processing technology to remove the stress-reducing thermal aging processing technology.

4. Save raw materials and try to reuse them. Because all raw materials must be consumed in the production.

5. Large-scale production by the precision casting company, that is, the production capacity of each forging module is above 5000t. Due to the large production capacity of the company, the operation time of the smelting furnace is long, and the heating consumption of the furnace itself can be greatly reduced on the energy consumption of one ton of castings.

6. Improve the management ability and reduce the unqualified rate.
