Round Ductile/ Cast Iron D400 Manhole Cover with Frame (DN600)



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:Question, such as title, I hope I don't copy the definition of rolling and casting in Baidu encyclopedia, thank you
The performance is too extensive, I think the following several people all fall into the erroneous zone directly, the performance includes a series of aspects:Mechanical properties: tensile strength, yield strength, elongation and contraction ratio of section and impact toughness after etc.
Q:As shown, how do I achieve the tightness test of this product, and achieve industrial production? Seek expert advice.
Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment
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:What is the difference between forging parts and casting parts?
No, it's called die castingDifference: the die casting parts are simple in structure and large in batch sizeCasting: the use of a wide range of structures without restrictions
Q:How to calculate the price of casting parts?
According to the complexity of the workpiece, material and casting requirements and process yield
Q:In the design of casting steps and precautions, for casting design, we have what experience?.
Two: the basic structure unit in the design of metal casting type and the parameters selected, usually should also pay attention to: (1) because of the metal type heat quickly, so the metal type casting minimum wall thickness should be bigger than the sand casting, metal type casting alloy minimum wall, different size of castings see table 1.1-31 thick can be selected; (2) the inner wall of the casting internal ribs and the thickness of wall thickness should be 0.6-0.7 connected, or as the inner wall (rib) cold slowly, cracks in the wall at the junction in the casting shrinkage;
Q:The casting sand is going on
Dispersed sand inclusion is common on the surface and subcutaneous of steel castings, often concentrated on the outer surface of the upper box and the inner surface of the lower case, and a few of them are inside the cast steel parts.
Q:What are the general technical requirements for casting parts?
Satisfy appearance quality (appearance defect, quality change, size deviation)Intrinsic quality (composition, properties, internal organization)Service performance (abrasion resistance, corrosion resistance, heat resistance, pressure resistance)
Q:What's the cause of the choking of the casting?,
2. when casting mold exhaust condition is not good, in the casting material use consider whether and hinder its gas permeability; in the process to consider to release more pores, multi venting; core exhaust is particularly important.
