- 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: How do casting parts remove stress?
- Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment
- Q: Casting parts by shot blasting, spray painting, baking after the formation of very small rust spots, how to solve ah?
- The first process is very important. Shot blasting must be thorough. The solution is to wipe the surface of the paint with a release. Re shot
- Q: What is the reason for 304 stainless steel precision casting parts to be changed?
- 304 stainless steel is easier to change than ordinary steel. Because the 304 heat conductivity is lower than that of the low doped steel, the temperature is even more uneven, and 20% of the non ferrous elements also make the distribution of internal and external elements more uneven, hard and soft inside. Each of these two produces greater internal stresses, resulting in a variant.
- Q: What should I pay attention to when designing a casting structure?
- 1 of the casting in metal mold cooling was faster than sand, metal type and let, thus casting in metal mold casting, casting stress generated in the ratio of sand casting to crack tendency is also large, but also prone to misrun and cold lap, white (for casting casting). Defect. Usually: (1) in the prevention of metal casting casting crack aspect should pay attention to the following problems: the structure of A in wall thickness, wall transition and connection to the ease, corner fillet appropriate requirements such as should be more strict than sand casting; B should be connected vertically connected with the wall to tilt C; for the weak parts of the structure should be set to strengthen ribs, bosses, to prevent casting; D should minimize the obstacle free shrinkage of the boss, casting rib, flange and other prominent part; E in the casting arrangement of ribs, but also should consider its influence on the casting shrinkage.
- Q: What is the casting material?
- Kdl1588n said in detail, casting a lot of material, steel, iron, aluminum, copper, zinc, etc. can be, valuable, as well as gold and silver, the most common on cast steel and cast iron, cast aluminum and so on.
- Q: Why should pig iron be used in casting?
- Not necessarily is iron, steel, stainless steel, aluminum, copper can be cast iron, is cheaper, and better properties of cast out, for example, is not easy to rust, high strength, easy processing and so on, and is the only iron iron cast out, it is not necessarily the raw pig iron, plus some other material
- Q: Is 316 casting better than 304 casting?
- It is comprehensive. There is no simple comparison of the material to determine the degree of difficulty in processing
- Q: Shandong foundry, casting small pieces of precision casting
- Dongying Huayang precision casting factory, the smallest to do 2G pieces.
- Q: ZGMn13 casting parts processing, with what knife head good?
- its surface wear resistance is high; the two is with the gradual wear of surface hardening, the hardening layer is continuously formed new if you have suggestions, processing, plasma cutting or flame cutting try
