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:It's not easy to drill ductile iron with cobalt high speed steel bit. Please help to point it out
Choose carbide or whole carbide drill, about 90HRC in hardness. But it requires a high number of drills, around 3000.
Q:How much is a ductile iron pipe dn400?
Ductile iron pipe nominal diameter is 80 ~ 2200 mm, compared with grey cast iron, high strength, good toughness, thin wall metal, less dosage, and can withstand high pressure, effective length of 5 meters, 6 meters and 8 meters; according to the different thickness of P, G two. It is the development direction of cast iron pipe.
Q:What's the function of the cement mortar lining of ductile iron pipes?
You may easily say that this statement is vague and there is no evidence that other manufacturers often do so when promoting other types of lining. However, in order to prove the truth of the above view, we have compiled sufficient examples to demonstrate the reliability of each of these statements from a scientific and logical point of view.We have stated each of these fields and other embedded systems as specious statements. There is only a reasonable conclusion that the cement mortar lining (CML) provides excellent protection for ductile iron pipes and steel tubes.Ductile iron pipe and steel pipe CML CML produces a synergistic effect of the incomparable.
Q:What is the manufacturing process of ductile iron pipes? Thank you
Ductile iron pipe is a pipe dream of urban water supply, gas pipelines, sets of high strength, good ductility and corrosion resistance strong strength, has the essence of iron, steel, cast iron pipe and steel pipe is a traditional popular replacement products, is a kind of widely used pressure water supply, gas and send pipes. Has the advantages of high strength, good toughness, corrosion resistance and easy device and other excellent characteristics, is the traditional grey iron and steel pipe replacement products popular, has become the preferred data of water supply, gas industry, set high strength, good ductility and corrosion resistance strong strength, has the essence of iron, steel, is the traditional cast iron pipe and steel pipe replacement products under the popular small as you introduce the ductile iron pipe is how to make the.
Q:What does "K8" mean in ductile iron pipe grades?
K9 is GB, K10 is specially customized, K8... Strictly speaking, it is not up to standard, standard length, wall thickness and so on.. Many workshops, grades of factory products, such as K9, standard length 6.15M, K8 is 6M, wall thickness from the beginning of DN100, are thin on the point.
Q:What is cast iron pipe?
Cast iron pipes (Cast, Iron, Pipe), cast cast pipe. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings. Labor intensity is small. According to the casting method, it is divided into continuous cast iron pipe and centrifugal cast iron pipe, in which the centrifugal cast iron pipe is divided into sand mould and metal type two kinds.
Q:Method for joining cast iron pipes
The connection between the pipe and the pipe adopts the form of socket type or flange disk interface. According to the function, it can be divided into two kinds: flexible interface and rigid interface. The flexible interface is sealed with rubber ring, which allows a certain degree of corner and displacement, so it has good seismic resistance and tightness. It is easy and quick to install than rigid interface. It has little labor intensity according to the casting method.
Q:Ductile iron 600-3 grade, tensile strength, how to test, there is a simple way?
General use of tensile machines, such as quality management, this aspect should be strictly controlled, otherwise the data is not accurate, do nothing, no one wants
Q:What material is ductile cast iron 235A?
Pig iron is an alloy of iron and carbon carbon content more than 2%, pig iron carbon content is generally in 2.5%--4%, including C, SI, and Mn, S, P and other elements, is the use of iron ores in blast furnace products. According to the different forms of carbon in pig iron, and can be divided into pig iron, cast iron and steel ball ductile cast iron. Several precipitation of spherical graphite cast iron. The cutting action on the metal substrate than spheroidal graphite flake graphite cast iron, the strength of the matrix organization strength of 70 ~ 90%, the tensile strength is up to 120kgf/mm2, and has good toughness. Ductile iron chemical composition besides iron usually contains: the amount of carbon 3.3.8%, silicon 2.3.0%, manganese, phosphorus, sulfur and no more than 1.5% of the total amount of rare earth, magnesium spheroiditic agent.
