What are the methods for energy-saving production in precision casting?

Everyone knows that when casting parts, the module will be damaged if you are not careful. The occurrence of damage not only delays the staff's time, but also consumes the raw materials of the module. However, energy-saving production is being carried out in our country nowadays. Due to the influence of China's strategic policy, many of Dongguan's precision casting industry structures will change to green and environmental protection. So what are the methods for energy-saving production in precision casting? The following summary has a total of six points:

1. Save raw materials and reuse them as much as possible. Because all materials are produced, energy must be consumed.

2. The precision casting company produces industrially, that is, the annual output value of each forging unit is above 5000t. Because the company's annual output value is large, the working hours of the melting furnace are long, and the energy consumption of heating of the furnace itself can be greatly reduced by apportioning the energy consumption of one ton of precision castings.

3. Develop management capabilities and reduce the failure rate. For example, for a precision casting plant with an annual output of 5,000 tons, every 1% reduction in the failure rate is equivalent to an extra 50 tons of precision castings. According to one ton of energy consumption of 405 kgee, it can save 20 tons of standard coal a year, that is, one ton of precision castings. Reduced the energy consumption of 4kgee.

4. Select the reliability design and improve the processing technology to develop the honorable production rate of the processing technology of Dongguan precision castings. Under the premise of ensuring the quality of precision castings, modifying the pouring system software and applying hot thermal insulation gates can generally develop the export rate. If the export rate can be developed from 60% to 70%, it can reduce the energy by 14.3%. Consumption.

5. Choose high-compact molding machines and their contemporary core-making expertise to minimize the quality of castings and reduce the remaining amount of processing. Practical experience High pressure modeling design can make the quality of castings 3%-5% less than technical modeling design and general equipment modeling design, and the remaining amount of processing can also be maintained at 2-3 mm. Reducing the net weight not only saves energy in the precision casting production workshop, but also reduces the energy consumption of subsequent production and processing.

6. Use energy-saving production processes and effective institutions for production. For example, use self-hardening resin sand or surface dry type to replace clay sand air-drying type, saving energy consumption of air-drying casting; strict seasoning, clarification of the appropriate components of precision cast steel, selection of reasonable creative plans, and removal of castings in the as-cast state The ash or hard grains can be used to cancel the graphitization annealing process; the as-cast ductile iron shall be implemented, and the elongation after fracture shall be obtained in the as-cast state; the frequency harmonic oscillation aging processing technology shall be selected as far as possible. Remove the thermal aging processing technology to reduce the ground stress. Learning these will increase the efficiency of the company and save costs.
