Q:What are the requirements for casting steel castings?
2, the plane should be placed on the following.3, thin parts should be placed below.
Q:Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!
Valve sand core mold drying is not in place, excessive water content
Q:Casting parts, anodizing 20
The common material that can be anodized is aluminum alloy. It is recommended to use casting aluminum alloys, such as ZL102 and ZL105, which are commonly used as cast aluminium alloys. The processing of aluminum casting is easy. After processing, the surface of the whole part can be anodized. The color can be chosen.
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: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:When the blank is a casting, the margin is evenly distributed, how should rough machining? Twenty
Problem one,1, according to drawings, castings, material requirements and machine power, choose the right diameter of roughing tools, and can process this material blade type.2, according to the actual size of the casting blank, calculate the number and path of the knife, pay attention to small cutting depth, large feed, cutting width, to ensure that the tool diameter 80 - 90%, the amount of not full knife cutting, this tool and machine tool damage.Question two,If they can not change the casting blank allowance under the condition that the quantity large diameter cutter, such as milling cutter main angle 7560 degrees can give reasonable processing parameters, the same cutting depth should not be too large, because in the same machine power, tool diameter increases, cutting depth will need smaller.
Q:Why does the precision casting factory not usually make iron castings?
Because it is too cheap, the design of materials is cast iron, generally do not have very high requirements.
Q:Where is the difference in performance between the rolled and cast parts of the same part?
uch as: automobile transmission shaft adopts mechanical rolling machine with good performance, gray cast iron can play seismic effect effectively, with good thermal conductivity of radiator graphite in gray cast iron, the aircraft engine turbine blade by casting directional solidification casting and Dan Jingzhu.Do everything we can to make the best use of it, the advantages and disadvantages of rolling and casting, and you'll find it yourself, Baidu, depending on how you use it
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:Explain the heat treatment effect of casting parts, forging parts and welding parts
Good welding of low carbon steel (alloy), probably because the weld workpiece rigidity, fast cooling, the weld internal crystallization of brittle microstructure (martensite), so after welding or welding process welding using self heat, reasonable arrangement of weld, welding seam and heat affected zone heat treatment. The welding heat treatment is often used to preheat before welding, after welding withasbestos cloth covering slow cooling annealing, reach the purpose, its main function is to reduce the internal stress, improve the weld microstructure of martensite formation, reduce brittle tendency, preventing welding cracks.
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.
