In recent years, with the continuous improvement of the quality requirements of mechanical products, including material, dimensional accuracy, especially the improvement of surface quality requirements, resin sand this more advanced technology has been vigorously promoted. In addition, with the treatment of the original sand and the improvement of resin, catalyst, sand mixing equipment, technology and other aspects, the cost of resin sand has been reduced, but also greatly promoted the promotion of resin sand technology.

Characteristics of resin sand modeling:

1, high yield

The yield of cast iron is generally ≥92%, and 96 ~ 98% in higher cases.

2, the surface is smooth

It is 2-3 grades higher than ordinary wet clay sand molding, and its surface roughness can reach Ra12.5.

3, high dimensional accuracy

Due to the high strength of molding sand, the dimensional accuracy of casting is 2 grades higher than that of general tidal sand and sodium silicate sand, which can reach IT8 ~ 10 grade. Subsequent machining allowance can be reduced, tool wear is small.

4, the process is simple, easy to control

Type genus self-hardening resin sand molding, key points of equipment guarantee, as long as the good grasp of the process parameters can ensure the quality of the casting, so the operator's technical quality requirements is low, and save Labour, and reduce labor intensity, the output of per unit area of the casting workshop clay sand drying technique to double, deoxidization efficiency has greatly increased. At the same time, dust spots and scattered sand less, so the working environment is cleaner.


5, high work efficiency

Using resin sand modeling to improve the work efficiency, unit area of the workload increased, saving the workshop area.

6. Reduce labor intensity

Resin sand greatly reduced the core, modeling, sand, cleaning workers labor intensity.

Ii. Main technical indicators and parameters

1, production program: 20000T/year

2, production process: furan resin sand process

3, old sand regeneration system productivity: 20 tons/hour

4, sand mixing capacity: 20+15×2+10 tons/hour

5. Recovery rate of reclaimed sand: ≥95%

6, the amount of reclaimed sand reduction: ≤2%

7, reclaimed sand powder content: ≤0.3% (below 200 mesh, including 200 mesh)

8, sand temperature regulation sand temperature: ≤40ºC

9, sand mixing uniformity error: ≤±3%

10. Liquid material quantitative accuracy error: ≤±1.5%


Determination of regeneration and sand mixing ability


Annual output of 20000 tons of casting (1700 tons per month)


Single casting weight 100-8000 kg (take 1500 kg)


Sand-iron ratio is 3.5:1


300 working days per year (25 days per month)

Then the regeneration capacity is determined:


Q = KCS/DT2, where K- coefficient 1-1.5,C- monthly production, S- sand-iron ratio,

D- working days per month,T2- daily working hours

Q = 1.25×1700× 3.5/25 ×16 =20 tons/hour

20 tons/hour.

Iii. Process flow and description
