Q: Casting parts need to be subjected to the kind of heat treatment after the weldment is finished
Annealing is needed to eliminate stress and refine grain
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?
If it is not directly cast hole hole, later processing, large pores may be directly cast out,
Q: What is the reason for 304 stainless steel precision casting parts to be changed?
Steel deformation control is one of the most common problems in the metal processing industry. Any process will occur. The casting is the largest deformation and the least fine. It is generally used to produce blank blanks
Q: What's the density of the cast iron? The density is thin and the density is thin
There is a hot knot in the thick area, which easily causes microscopic shrinkage and makes the casting not dense. A riser may be added for shrinkage relief.
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: How to cast iron and wrought iron collocation
2, listen: Pig beating sound boring, wrought iron beating sound loud.
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: How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
Hot galvanizingGenerally 0.06 mm or more
Q: Heat treatment process and purpose of casting parts
Objective: to stabilize tissues, eliminate or substantially reduce internal stress.
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?
Usually manual molding optional CT11 class, ordinary machine modeling optional CT10 class, high pressure molding should reach CT9 level. The tolerances on the wall thickness of the casting are comparable to those of other dimensions of the same casting.
