- Q: What are the factors affecting the machining process of the casting material and structure?
- The impact on the machining is obvious, it should be the material and heat treatment of the castingCarbon steel parts should be treated by heat treatment (annealing) without special conditions. It can effectively prevent the uneven hardness and hard points. It is easy to turn.
- Q: our factory now produces steel castings in the use of polishing directly after spraying processing, but the powder sprayed 15But the spray powder touched off what is the reason we are not very strict requirements not only need to peel off bubbles can also, because our products are steel castings so we use steam hole sludge put on. Do not know if this spray treatment has no effect to thank friends with us!
- Steel parts are not familiar. But after spraying, the powder should be divorced from the adhesive force is too low, try to provide the surface roughness of the casting
- Q: Domestic large steel castings factory which is better, recommend!
- At least spend money on research and development, then the quality should be all right.
- Q: I often see Waixiejiagong drawings, casting, how to distinguish the latheman.
- Yes, casting drawings are casting drawings with machining allowances, slopes, and gating systems
- Q: The cause of fracture and why there is no toughness
- This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.
- Q: For example, casting parts contain many holes, inclusions and other defects, the size and the number of holes exceed which limit is not qualified
- According to different casting process and parts materials, each has relevant standards, can be found online;
- Q: What do you mean by "proofing" in the casting? Do you charge for the proofing?
- Proofing refers to making the first sample to confirm to the customer
- Q: Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?
- The tolerance of a specific size can be obtained from the tolerance grade and nominal size of the casting.
- Q: In the design of casting steps and precautions, for casting design, we have what experience?.
- Two: the basic structure unit in the design of metal casting type and the parameters selected, usually should also pay attention to: (1) because of the metal type heat quickly, so the metal type casting minimum wall thickness should be bigger than the sand casting, metal type casting alloy minimum wall, different size of castings see table 1.1-31 thick can be selected; (2) the inner wall of the casting internal ribs and the thickness of wall thickness should be 0.6-0.7 connected, or as the inner wall (rib) cold slowly, cracks in the wall at the junction in the casting shrinkage;
- Q: Is 316 casting better than 304 casting?
- The degree of difficulty in the process of casting depends mainly on the structure, precision requirements, and hardness of the casting. It is comprehensive. There is no simple comparison of the material to determine the degree of difficulty in processing
