Q:What is the disadvantage of nodular cast iron in excess of silicon?
Therefore, the increase of silicon content in nodular iron greatly improves the strength index and reduces toughness. Ductile iron has a greater crystalline undercooling and a tendency to chill when treated by spheroidizing, and silicon reduces this tendency.
Q:The role of chromium in nodular cast iron
In order to further understand the mechanism of chromium in ductile iron, the application of electronic scanning and other test means, from chrome crystal structure, crystallization, solidification, heat treatment transformation principle, further study on the mechanism of chromium in ductile iron.
Q:What is the relationship between continuous cast iron pipe and ductile iron pipe?
Cast iron pipes are divided into continuous cast iron pipes and centrifugal cast iron pipes according to different casting methods. They are divided into gray cast iron pipes and ductile iron pipes according to different materials.
Q:An urban infrastructure construction, water supply pipe is ductile iron pipe and PE pipe, thank you
Because the construction of municipal water supply pressure will be relatively large, generally used in the selection of pipe centrifugal ductile iron pipe, he has properties of iron essence and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, ductile iron pipe is mainly used for municipal, industrial and mining enterprises, water supply, gas, oil etc.
Q:What does ductile iron pipe "K" mean?
K means wall thickness registration, general water supply and drainage, now China uses K9, and some countries in South America, such as Brazil, use K7.The wall is thick =k (DN/1000+0.5), such as K9's DN500 tube, with a wall thickness of =9* (500/1000+0.5) =9mm
Q:What new technologies are there for the installation of ductile iron pipes?
The latest installation technology is the use of cast iron pipe special installation tools, a person can be convenient and efficient operation, 5 minutes an interface, very convenient, called cast iron pipe installation tool, you can search.
Q:Advantages and disadvantages of ductile iron pipes?
The ductile iron pipe has a single length of 6 meters and a large wall thickness. The cast iron tube has a single branch length of 3 meters and a thinner wall thickness.
Q:What's the difference between ductile iron pipe and cast iron pipe?
Ductile iron pipe is based on cast iron, changed some of the characteristics of the structure of iron, so that it has become a lot of toughness, than the cast iron pipe is too brittle shortcomings much better, the tensile strength of the pipe bending strength greatly improved. The sealing material used in the socket interface is rubber ring.
Q:Will the quality of ductile iron shrink?
I am a professional casting, I can certainly tell you what he said, there is no basis, you see, the concave is due to do not have a good time, where the hot metal supplement
Q:Method for cutting large diameter ductile iron pipe
When the volume ratio of oxygen and acetylene is less than 1, a carbonized flame is obtained. Because of less oxygen and incomplete combustion, the flame is longer than the neutral flame and the temperature is lower. Acetylene in the carbide flame is suitable for welding high carbon steel, cast iron and cemented carbide materials. When welding other materials with a carbide flame, the weld metal becomes hard and brittle.
