- Q: What are the factors affecting the machining process of the casting material and structure?
- As for the metallographic structure, usually the finished products after casting are treated by heat treatment. The mechanical properties of the carbon steel after heat treatment (quenching and tempering) are detected. The stainless steels are treated by heat treatment (solid solution, etc.) and the metallographic structure is analyzedThere is a lot of talk and a bit of confusionIf you have a specific brand, you can search for Baidu or buy tools
- Q: In theory, which is more expensive, forging parts or casting parts?
- The structure of the casting is relatively flexible in design, and the modeling is easy to realize.
- Q: I often see Waixiejiagong drawings, casting, how to distinguish the latheman.
- The technical condition or the material column in the title column will tell whether it is a casting drawing or not. However, the need for casting drawings, and some also through machining (car, milling, etc.), this should be part of the process drawings, process drawings are described
- 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: What's the density of the cast iron? The density is thin and the density is thin
- Generally cast iron thick place, density is empty, thin place density a little more.
- Q: What are the causes of pitting on the surface of a precision casting?
- The quality of the shell surface is out of order. Or shot blasting out of question.
- Q: What is the casting material?
- Gray iron, carbon steel, low alloy steel, ductile iron, stainless steel, Aluminum Alloy can all be cast out
- Q: How do you mark it on the drawing? Do you need to discuss it with the manufacturer?Because the casting allowance is the standard, then, after all, is the theoretical value, the actual level depends on the manufacturer, so is it necessary to ask the manufacturer?
- Casting parts do not need to provide drawings of casting blank, the casting factory according to your drawings in the required surface will be sufficient allowance, and the rest of the size according to the mechanical design manual and the casting manual can be found.
- Q: Would you please tell me how to use casting parts for a year?The cast of an aircraft wing needs to be put aside for a year before it breaks;Does anyone know why?
- 2, heat aging (artificial aging), also known as stress annealing, is to heat the casting to 550-650 degrees, insulation 2 - 4h, with the furnace cooling to 150 - 200T, and then baked.
- Q: When there is no flaw detection for large casting parts, is there any crack inside?
- According to the industry standards, within the scope of the standard requirements to determine whether the product is qualified
