Cast iron than other parts of the advantages of what?

1 repeatability is good, has the characteristic of precision casting;

The surface finish of 2 cast iron with high degree of;

3 cancelled the sand core and core making section,eradicates the casting defects and waste system core, corecaused by;

4 different box, not from mold, which greatly simplifies themodeling process, eliminating the casting defects and waste from mold, caused by the combined box;

5 no adhesive used, no water, no additives dry sand molding, eradicates the various water, additives andbinders caused by the casting defects and waste;

6 greatly simplifies the sand processing system, sand can be fully reused, cancelled the sand preparation departmentand waste of sand preparation;

7 shakeout is extremely easy, greatly reducing theworkload and labor intensity of falling sand;

8 cast iron without burr, the cleaning and polishingworkload is reduced by more than 50%;

Riser 9 can be set reasonable shape in the ideal position,and is not restricted by typing, modulus and othertraditional factors, reducing internal defect of iron castings;

The 10 negative pressure casting, more conducive to theliquid metal filling and feeding, improves iron tissue density;

11 combination casting, many boxes, greatly improving thetechnics of cast iron production rate and productionefficiency;

12 reduce machining allowance, reduces the cost of machining;

13 it is easy to realize mechanization and automated production lines, production line elasticity, can realize different alloy, on a production line of different shapes,different sizes of iron castings production;

14 may cancel the draft;

15 the service life of the metal mold can reach more than 100000 times, reducing the die maintenance costs;

16 reducing the dust, dust and noise pollution, greatly improves the foundry workers work environment, reduces the labor intensity, with the male dominated industry can become to female dominated industry;

17 the process operation is simplified, the requirement on the technical proficiency greatly reduced;

18 the shape of the parts from the casting process of the limitation of traditional mechanical design, the liberation of the workers, according to the service performance of the parts, can be free to design the ideal shape of cast ironparts;

19 can reduce the iron weight;

20 reduced the cost of production;

21 simplified plant design, investment in fixed assets can be reduced by 30 ~ 40%, covers an area of and building areacan be reduced by 30 ~ 50%, the power consumption can be reduced by 10 ~ 20%;

22 iron casting technology is widely used, not only suitable for cast steel, cast iron, more suitable for copper and aluminum etc.;

23 iron casting technique is not only suitable for cast iron parts with simple geometries, more suitable for ordinarycasting difficult to start more than open iron core, edge,more complicated geometry;

24 cast iron casting process can realize the microseismicstate, promote the formation of microstructure of special requirements, is conducive to improve the intrinsic quality of iron castings;

25 in the dry sand casting sand removal combination, easytemperature synchronization, therefore can be heat treatedusing waste heat. Especially the high manganese steelcastings water edge processing and heat-resistant steel castings solid solution treatment, the effect is very ideal,can save a lot of energy and shorten the processing cycle;

26 the use of cast iron melting process, according to ability,cast iron pieces to complete any size.
