Q: How to improve the surface roughness of casting parts?
One is to improve the accuracy of the model; the two is to improve the molding sand mesh. How much is the other relationship?.
Q: What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?
The aim is to make the grain fine and distribute the carbide evenly. The difference between normalizing and annealing is that normalizing cooling rate is slightly faster than annealing cooling rate, so normalizing structure is finer than annealing structure, and its mechanical properties are also improved. In addition, normalizing furnace cooling does not occupy equipment and has higher productivity. Therefore, normalizing may be used instead of annealing as much as possible. The main application areas of normalizing are as follows: for low carbon steel, after normalizing, the hardness is slightly higher than that of annealing, and the toughness is better. It can be used as the pretreatment of cutting. Used for medium carbon steel, instead of quenching and tempering, as the final heat treatment, or as an induction heating method before surface hardening. Used for tool steel, bearing steel, carburizing steel, etc., it can eliminate or restrain the formation of network carbide, so as to obtain the good organization of spheroidizing annealing. For cast steel, the microstructure can be refined and the machinability can be improved. Used for large forgings, which can be used as final heat treatment, so as to avoid larger cracking tendency during quenching.
Q: Casting parts need to be subjected to the kind of heat treatment after the weldment is finished
Annealing is needed to eliminate stress and refine grain
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: What method of casting does not rust? I think the sample is like oil
The surface of a general casting is easy to rust. In order to prolong the rusting period, antirust paint or antirust oil is usually sprayed. What you said should be anti rust oil.
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: 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?
3, the resonance method is cast on its resonant frequency vibration 1060ndn, to eliminate the residual stress in casting.
Q: Why do casting parts have air holes?
First, from the source, tools, raw material drying, in the process of melting into the reaction gas, another influence is pouring process, such as high temperature solidification gas dissolved too much after not excluded. The method can adjust the pouring temperature properly, control the source of gas (drying and controlling the inoculant, especially the content of magnesium), and add cooling iron to change the solidification mode. It depends on what kind of casting you are. You can't make it clear at once. And molding sand relationship is mainly water content and permeability, brush coating resin content.
Q: When there is no flaw detection for large casting parts, is there any crack inside?
Cracks are considered serious levels of defects and should be repaired
Q: The difference between sheet metal and casting parts
Sheet metal refers to the metal sheet (which can be bent straight board, etc.) generally uniform thickness, can obtain the required parts by stamping, molding, welding, splicing and other processing methods.
