Q:What method of casting does not rust? I think the sample is like oil
The surface of a general casting is easy to rust. In order to prolong the rusting period, antirust paint or antirust oil is usually sprayed. What you said should be anti rust oil.
Q:What are the casting parts processing engineering?
According to the classification of process methods, sand casting and special casting.
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:Cause of choking of casting parts
The reason is not in the coated sand, see coating gas evolution, the best use of zircon powder coating (low gas evolution), there is a mold according to a vent needle, this depends on your way is flat or vertical pouring pouring pouring, if vertical pouring, venting pin on the die, and the big piece how could the plane, pouring water flat, a breath, a taboo ah!
Q:Heat treatment process and purpose of casting parts
Natural aging (also known as Chang Hua): lost in the open, the sun and rain, can have experienced years of wind and frost.
Q:What is the difference between the casting drawing and the car work drawing?
What you say is the difference between rough drawing and processing drawingThere must be a difference between the rough drawings and the rough ones
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 is the ejection angle of the die casting (Tan Gang)?
Especially deep hole, and customers to discuss, generally take 0.3-1 degrees is enough
Q:In theory, which is more expensive, forging parts or casting parts?
It depends on the structure. In theory, the shape of the forging is relatively simple, but the requirement of internal structure is relatively high
Q:Which surface is coarser for cast iron or cast steel castings? Why?
The surface of the steel is more rough, because the coating sand cast steel cast iron particles compared with graphite coating degree, the other one is to get a better air permeability and collapsibility of sand, the compaction degree is smaller than iron. Roughness mainly depends on the surface roughness on the surface of the sand.
