Q: How to improve the surface roughness of casting parts?
First, the accuracy of the model should be improved; two is to change the molding technique; the three is the coating; and the worker's technical level.
Q: What's the effect of casting copper?
Riga. Copper is copper components, promote the graphitization of the copper element, make dense tissue, and to refine and improve the uniform distribution of graphite, which can reduce the chilling tendency of the cast iron, but also can promote the formation of pearlite, has a favorable effect on the section sensitivity. Copper has the tendency to strengthen cast iron, ferrite and pearlite, so it can increase the strength of cast iron. The tensile strength and bending strength of cast iron almost increase with the amount of copper in it, especially in low carbon cast iron.
Q: What are the requirements for casting steel castings?
4 thickness, most should be placed above the.5 and try to reduce the number of.6, the sand core should be used in classification of flat surface
Q: What are the casting parts tested?
The surface brightness, appearance, size, chemical composition, weight, material, surface defects, internal defects, seals need to be checked, leakage, etc.
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: How to distinguish the forging parts and casting parts accurately
Distinguishing between forging and casting can be done from the following points:From the principle of distinguishingForging processing of machining by hammer or press and other equipment for forging parts produced in hot state, casting processing of metals into liquid, pouring into the cavity with a specific shape, produced by machining parts after cooling solidification. Simply say that forging is the metal soft pinch molding, and casting the metal into thin cooling solidification.
Q: Why do casting parts have air holes?
Cangshan Qiao hidden his answer is quite comprehensive, you can try using inert gas to reduce air cover
Q: How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.
Q: What reason is the bronze statue choking fire?
The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,
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
