- Q: How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.
- The material is usually steel material price plus the cost (per ton of 2.5-3 million, plus profit).In the Yangtze River Delta region, generally 304 casting price of about 5-5.5 million / ton.The price will be higher if the parts are complex, or a piece weighs less than 100 grams.
- 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: 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: What are the requirements for casting steel castings?
- 1, high quality requirements of the surface or the main processing surface should be placed below.
- Q: It is generally said that cast iron is re smelted by pig iron. My question is..:1 pig iron for melting iron, is directly cast into products (such as bed cover, etc.); or that is just the first pig iron smelting iron casting, such as to cover, bed and other products, will once again cast iron melt to casting?2, there are many castings to the engine. Are these castings made by the engine manufacturer themselves or bought by others?There is no need to answer all. Thank you!!!
- The first to ask, such as casting end cover, bed and other products, is to put the iron melting and casting againThe two question, their casting castings manufacturers than to buy professional casting factory production, production quality more security professional.
- Q: How can the casting be quenched and tempered?
- Another is the result of pre heat treatment (quenching or annealing) after quenching and tempering treatment, suitable for ZG35SiMNMo, ZG35CrMo and so on. Please tell the casting process is your product and material and then set tempered.: shutup:
- 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?
- There are various casting stresses after casting, which can be divided into two kinds: thermal stress and shrinkage stress. In a long time placed in the atmosphere, called aging treatment.Aging treatment is an effective measure to eliminate casting stress. Aging is divided into natural aging, thermal aging and resonance aging.1, the so-called natural aging, the casting is placed in the open field for more than half a year, so that the internal stress relief.
- Q: Where is the precision casting factory?
- The National Precision Casting Factory is generally distributed in Shandong, Ji'nan, Jiangsu, Wuxi, Changzhou, Zhejiang, Guangdong, Panyu, Dongguan.The above are only the main distribution, many of Shandong are made supercharger, and Guangdong to jewelry industry based.
- 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
- Q: Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!
- Valve sand core mold drying is not in place, excessive water content
