FAQ
Why imported Composite Manhole cover/Grating fromChina?
1. Very competitive price, it will save you third or even half cost;
2.Good quality, don't worry much about the quality, actually, most of the building materials you buy from Miami, Dubai ,Italy, South Africa or your local market are imported from China. So why not buy direct from China. The key point is to find a reliable supplier who is honest and professional to take care of the quality and delivery time.
3.Chinahas full range of Manhole covers which Follow En124 for your market, like A15,B125,C250,D400.

- Q: What are the factors affecting the machining process of the casting material and structure?
- As for the metallographic structure, usually the finished products after casting are treated by heat treatment. The mechanical properties of the carbon steel after heat treatment (quenching and tempering) are detected. The stainless steels are treated by heat treatment (solid solution, etc.) and the metallographic structure is analyzedThere is a lot of talk and a bit of confusionIf you have a specific brand, you can search for Baidu or buy tools
- Q: Why does the surface of stainless steel casting mirror mirror ripple?
- Because the grinding machine is layer by layer. And the material inside the casting is not completely uniform.
- Q: Casting parts need to be subjected to the kind of heat treatment after the weldment is finished
- 1, gray cast iron: General graphite annealing, to be heat treatment annealing, surface hardening etc.; ductile iron can be various: annealing, normalizing, quenching and isothermal quenching, surface treatment, chemical heat treatment.2. Pouring liquid metal into the casting cavity which adapts to the shape of parts. After cooling and solidification, the casting method is called casting. Castings obtained by casting are called castings. Casting structure design: ensure the working performance and mechanical performance requirements, consider the technical requirements and performance of alloy casting casting casting structure, casting structure design is reasonable or not, the casting quality, productivity and cost has a great influence.3. Heat treatment is a metal hot working process in which the material is in solid state by means of heating, heat preservation and cooling to obtain desired microstructure and properties
- Q: What kind of casting process is used for cast iron parts? And what are the cast steel parts adopted?
- The types and uses of foundry sand according to the mineral composition of different silica sand and non siliceous sand is divided into two categories. The main mineral composition of silica SiO2.: natural silica sand used for non-ferrous metal casting, cast iron and steel castings in small sand and core sand. The selection of natural silica sand: used in organic matter as the binder of various sand and core sand. The artificial sand for sand and core sand castings. Non siliceous sand and non siliceous sand have many kinds and different uses. Limestone sand: crushed by limestone, the main mineral composition is CaCO3, used for casting sand and core sand. Zirconium sand: the main mineral composition is ZrO2 SiO2, used for large steel castings and alloy steel pieces of core sand or sand surface sand, or powder used as coating. Magnesia: the main mineral composition is MGO, used for high manganese steel casting surface sand, core sand, and its powder can be used as coating. Chromite ore: the main mineral composition is chromite FeO. Cr2O3, used for large or special casting steel surface sand, core sand, its powder can be used as coating.
- Q: The difference between cement sand castings, resin sand castings and vacuum casting parts
- Vacuum casting is the process of using ventilation molds. Molten metal flows into the mold by air pressure, and then removes air to form a vacuum. The casting process is mainly used for small parts or jewelry with exquisite detailsCompared with the traditional clay sand casting, heat hardening resin sand casting production with low surface roughness, high precision, good quality characteristics, dimensional accuracy of resin sand mold after hardening with good rigidity and high, and not easy to deform, so in the choice of process parameters, mechanical processing you can select a smaller margin, thereby reducing the consumption of metal solution and machining cost, which can improve the dimensional accuracy of castings.
- Q: Question, such as title, I hope I don't copy the definition of rolling and casting in Baidu encyclopedia, thank you
- uch as: automobile transmission shaft adopts mechanical rolling machine with good performance, gray cast iron can play seismic effect effectively, with good thermal conductivity of radiator graphite in gray cast iron, the aircraft engine turbine blade by casting directional solidification casting and Dan Jingzhu.Do everything we can to make the best use of it, the advantages and disadvantages of rolling and casting, and you'll find it yourself, Baidu, depending on how you use it
- Q: Where is the precision casting factory?
- Shandong, DongyingThe birthplace of precision casting
- 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.
- Q: Why should pig iron be used in casting?
- Popular name is called pig iron, in fact, is a kind of cast iron without treatment, after casting, in iron elements to add other elements to improve casting performanceIt mainly improves the fluidity, reduces the melting point and reduces the shrinkage.Usually pure iron and cast iron at the eutectic point (about 4.7% carbon content) can be used for castingThere are many kinds of cast iron, usually grey cast iron, ductile iron and vermicular graphite iron......
- 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,
