- Q: What are the casting parts used to test shrinkage holes?
- 2. x ray. This method can do nondestructive testing, but the cost is higher. Generally, high castings are required.
- Q: How to get rid of casting sand inside casting parts?
- Are you saying that in the sand casting cavity? We use the manual blast, he is like a pipe will be automatic shot out of the grit, into the casting cavity, to remove the internal cavity in the purpose of casting sand!
- Q: Selection of hydraulic press is the casting parts and steel plate welding, how to choose?
- Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.
- Q: I often see Waixiejiagong drawings, casting, how to distinguish the latheman.
- What you say is the difference between rough drawing and processing drawingThere must be a difference between the rough drawings and the rough ones
- Q: What should I pay attention to when designing a casting structure?
- (2) in the prevention of metal mold casting misrun and cold partition should pay attention to the following problems: the structure of A casting thickness should be appropriate not too thin, especially when casting size when not too thin; the B should avoid a big level, because it makes the liquid metal in the casting. Rise slowly, and the air contact surface, easy oxidation, and because the metal type liquid metal heat quickly, quickly lose liquidity, easy to cause misrun and cold lap, slag and other defects; C casting shape should be streamlined to avoid sharp corners and has sharp change connection structure in order to facilitate the flow of liquid metal. 2 in the design of metal castings in a complex shape, if the production process is very difficult, should not affect the casting conditions, try to make the casting has simple shape, strong structure change, removed from metallic die for.
- 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: What are the causes of pitting on the surface of a precision casting?
- There is a bump on the mold. Or casting cooling fast.
- 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: In the design of casting steps and precautions, for casting design, we have what experience?.
- (3) to prevent generating white grey cast iron, in addition to taking measures from the process, must make the wall thickness is not too thin (some sources indicate that the corner wall thickness above 15mm, metal type casting must be in the corner, for Aluminum Alloy, magnesium alloy casting casting casting Create fillet should not be less than 3-4m, for casting round cast iron, copper alloy mould casting can see table 1.1-32 selection; (5) because of the metal and the core without let, for the convenience of the casting is taken out and the draw out type, slope casting casting should be suitably large than sand casting metal casting. General 30%-50%, it should be pointed out that in addition to the height of the slope of casting size and alloy type, wall, is also related to the casting surface position, where the cooling and contraction and metal surface of casting surface can be designed from the tendency of small inclination, while casting shrinkage tend to be pressed on the surface of metal castings the type should be given greater inclination, all kinds of metal type alloy casting casting casting.
- Q: How to solve casting defect casting?
- Different defects, different solutions, some shortcomings, the current domestic level can not be resolved
