- Q: Explain the heat treatment effect of casting parts, forging parts and welding parts
- 2 improve the crystal structure, enhance the formation and stability of spherical carbon crystal;Forgings are generally stress bearing members, and most of them are made of high strength medium carbon steel (alloy), which is formed by forging and fine crystalline. After the shell is annealed or quenched and tempered, the mechanical properties of the shell are more superior, and it has better strength and better elasticity;Welding materials.
- Q: What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?
- 3, weight: if reinforcement in products, casting weight is generally greater than the welding parts (the internal organizational structure and mode of production determines the mechanical properties of materials, so it determines the weight of the product), considering the cost of transportation, certain priority structure.
- Q: In theory, which is more expensive, forging parts or casting parts?
- Compared with the price, the product with the same simple structure eliminates the material factorsThe forgings must be more expensive
- Q: What is the reason for 304 stainless steel precision casting parts to be changed?
- Steel deformation control is one of the most common problems in the metal processing industry. Any process will occur. The casting is the largest deformation and the least fine. It is generally used to produce blank blanks
- Q: How can the casting be quenched and tempered?
- Cast steel annealing or normalizing parts in strength and toughness is insufficient, can be used in quenching and tempering treatment. It is mainly used for gear, gear and other parts of the cast steel. The conditioning has two kinds: one kind is cast directly after quenching and tempering, with warm water (40---50 degrees) intermittent cooling, suitable for ZG270---500, ZG310----570 and other castings.
- 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: Why do casting parts have air holes?
- Cangshan Qiao hidden his answer is quite comprehensive, you can try using inert gas to reduce air cover
- Q: Cause of choking of casting parts
- Is it boiling from the picture? Does it sound like a fire? If not, it's not choking. I feel like choking. The gas doesn't drain out
- 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.
