Q:How to distinguish the forging parts and casting parts accurately
Distinguishing between forging and casting can be done from the following points:From the principle of distinguishingForging processing of machining by hammer or press and other equipment for forging parts produced in hot state, casting processing of metals into liquid, pouring into the cavity with a specific shape, produced by machining parts after cooling solidification. Simply say that forging is the metal soft pinch molding, and casting the metal into thin cooling solidification.
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:How much is the casting allowance in the design of the casting machine and the drawing?
The general foundry casting technology division will mark put shrinkage and the allowance of the map in your chart (usually with the red pen) for the production of wood or other material wood workers die drawings.
Q:What are the general technical requirements for casting parts?
According to the national standard GB/T 9438, there are 8 aspects: 1. chemical composition; 2. delivery status; 3. mechanical properties; 4. dimensional tolerances; 5. weight tolerances; 6. appearance quality; 7. internal quality; 8. casting salvage.
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:When the blank is a casting, the margin is evenly distributed, how should rough machining? Twenty
Even distribution is a good thing. Generally, the machining allowance of the casting is uneven.If the processing depends on how your processing techniques have been arranged.In the NC milling plane contour machining, when the rough margin is large, how to deal with.1. Return to the foundry, too large margin improvement.2. Then you can spend more time on it.
Q:Why should pig iron be used in casting?
1, in the absence of special requirements, the most important thing is that the price is cheap.2, pig iron castings quenching process requirements are not high. You can do it by hand.3, pig iron casting hardness is very large, can meet many requirements.4, pig iron castings, high temperature resistance is relatively strong. Like stoves are pig iron castings.5, pig iron casting plasticity is very bad, but in some experiments, but use this weakness to improve the sensitivity of the experiment.Wait
Q:What kind of flaw detector is better for casting parts?
If you want to detect internal defects, you can use ultrasonic flaw detector, ray flaw detector can also, but the ray of the safety protection level is too high, not recommended priorityMacro Xu flaw detector answered, such as the magnetic particle inspection machine has the demand can contact us, Baidu "macro Xu flaw detection""
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:Which surface is coarser for cast iron or cast steel castings? Why?
Roughness mainly depends on the surface roughness on the surface of the sand.
CGBM established in 1995, the largest and most specialized casting and forged products supplier in China. Min products are grinding media balls, grinding rods, cylpebs, mill liners and steel flanges, with specifications all reaching international standards and annual production capacity is over 150,000tons.
