- 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: What's the effect of casting copper?
- In general cast iron, the mass fraction of copper below 3% - 3.5% can increase the hardness; but when the cast iron has a tendency to chill, or when there is a hard point of free carbides, the addition of copper decreases the hardness.Copper can be used to improve the wear resistance, abrasion resistance, and shock absorption of cast iron, so it is often used in the manufacture of sliding friction iron castings, such as drilling machine spindle, automobile and tractor, valve tappet, etc.. But in white cast iron or chilled cast iron, adding copper does not make any improvement in its abrasion resistance.Copper for certain heat resistant cast iron and austenitic cast iron can increase the heat resistance and corrosion resistance, copper - chromium composite alloy to prevent oxidation under high temperature in the atmosphere from the skin effect is particularly effective, heat resistance and corrosion resistance of austenitic cast iron containing many mass fraction of 4% ~ 7% copper.
- Q: Domestic large steel castings factory which is better, recommend!
- Do the casting manufacturer of large steel castings, Hunan Jinsha heavy industry science and technology limited company, heard that their professional only more than 1 tons of steel castings, anyway, 150T just big, the company won a lot of foundry industry patents should be good. At least spend money on research and development, then the quality should be all right.
- Q: Is the cast steel a casting part?
- Cast steel is divided according to material, as well as cast iron parts, cast aluminum parts and so onCasting parts are divided according to the method, as well as forging partsCast steel parts must be casting parts
- 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: The cause of fracture and why there is no toughness
- This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.
- 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: What is the difference between casting and stamping parts?
- Cold stamping is generally no longer done by cutting, or only a small amount of cutting is required. The precision and surface state of hot stamping parts are lower than those of cold stamping parts, but they are better than those of castings and forgings, and the amount of cutting is less.Stamping is mainly based on process classification, can be divided into separation process and forming process two major categories.
- Q: Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle
- Processing stainless steel materials, you can use YG class tools, such as YG8, YG8N. The tool geometric parameters g0=15 degrees to 18 degrees, a0=6 degrees to 8 degrees, kr=75 degrees, ls=-5 degrees to -8 degrees; cutting amount is Vc=43 m/min, ap=0.3 to 0.5 mm, f=0.16mm/r.
- Q: Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?
- Our country has a national standard for casting tolerance levels. This national standard applies to you in malleable iron, grey cast iron, and ductile iron.
