Q:What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?
For the nodular cast iron, the hardness, strength and wear resistance are improved, such as used in the manufacture of automobile, tractor, diesel engine crankshaft, connecting rod and other important parts. A normalizing and hypereutectoid ball annealing before, can eliminate the mesh two cementite spheroidizing annealing, to ensure that all spheres of cementite. Annealing is a metal heat treatment process, which means the metal is slowly heated to a certain temperature, sufficient for a long time, and then cooled at an appropriate speed. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize size, reduce deformation and crack tendency, refine grain, adjust microstructure and eliminate tissue defects. Its purpose: (1) reduce hardness and improve machinability; (2) eliminate residual stress, stabilize size, reduce deformation and crack tendency; (3) refine grain, adjust microstructure and eliminate tissue defects. In production, annealing process is widely used.
Q:Question, such as title, I hope I don't copy the definition of rolling and casting in Baidu encyclopedia, thank you
The performance is too extensive, I think the following several people all fall into the erroneous zone directly, the performance includes a series of aspects:Mechanical properties: tensile strength, yield strength, elongation and contraction ratio of section and impact toughness after etc.
Q:Why do cheap cars like stamping parts instead of casting parts?
We usually say that the stamping is usually refers to the cold stamping parts, for example, a piece of iron, wants to turn it into a fast food dish, it must design a set of mold, mold is working face plate shape, the pressure plate mold, it becomes you want the dishes, this is the cold stamping die stamping is the direct use of metal materials.Automobile stamping parts are mainly classified according to process, and can be divided into two major parts: separation process and forming process.
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:Casting parts have poor surface finish. What sand is used to make them?
V casting, EPC, precision casting of the surface is good.
Q:What are the causes of pitting on the surface of a precision casting?
The quality of the shell surface is out of order. Or shot blasting out of question.
Q:What do you mean by "proofing" in the casting? Do you charge for the proofing?
Proofing refers to making the first sample to confirm to the customer
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: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 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.
