FAQ
Why imported Composite Manhole cover/Grating fromChina?
1. Very competitive price, it will save you third or even half cost;
2.Good quality, don't worry much about the quality, actually, most of the building materials you buy from Miami, Dubai ,Italy, South Africa or your local market are imported from China. So why not buy direct from China. The key point is to find a reliable supplier who is honest and professional to take care of the quality and delivery time.
3.China has full range of Manhole covers which Follow En124 for your market, like A15,B125,C250,D400.
- 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 are the requirements for casting steel castings?
- 2, the plane should be placed on the following.3, thin parts should be placed below.
- Q: In theory, which is more expensive, forging parts or casting parts?
- The structure of the casting is relatively flexible in design, and the modeling is easy to realize.
- Q: the parts of the threaded hole is casting, casting the hole directly, and then tapping or casting, and then punch 10When the casting is ready, punch it again before tapping it Is the hole casting good or is it punched and tapped on the drilling machine after casting?
- Single for this problem, the direct casting out of course good. But many times because of the limitations of the process, so we choose the post-processing hole
- Q: Where is the precision casting factory?
- Everywhere is. Look what you want to do
- Q: Which surface is coarser for cast iron or cast steel castings? Why?
- Roughness mainly depends on the surface roughness on the surface of the sand.
- Q: Heat treatment process and purpose of casting parts
- Methods: artificial aging or natural aging (also called normalization) treatment.Artificial aging: heating to 2-3 Baidu, it is best to apply mechanical vibration, and maintain a period of time.
- 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.
- Q: What's the cause of the choking of the casting?,
- 3. when casting the environment is humid, sand mold has not removed the moisture, when the casting, the moisture instantaneous transforms into the steam, causes the blowhole
- Q: How can the casting be free of trachoma?
- Measures for the prevention of trachoma in castings:1, sand compaction to high, paint two times;
