YES! We are a professional ductile iron &gery iron casting Factory in China.
2.Q: How long can you make your quotation:
Within 3 workdays after received your detailed product information
3.Q: Do you provide OEM Service?
Yes, we provide OEM Service.
4.Q: What 's your quotation element?
Drawing, material, weight and quantity.
- Q: What are the casting parts used to test shrinkage holes?
- 3 fluorescent magnetic powder, this method can also be found in part.
- Q: What are the requirements for casting steel castings?
- 4 thickness, most should be placed above the.5 and try to reduce the number of.6, the sand core should be used in classification of flat surface
- Q: How do casting parts remove stress?
- Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment
- 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: What's the density of the cast iron? The density is thin and the density is thin
- Uneven casting density is caused by uneven shrinkage of the casting during solidification.
- Q: Why should pig iron be used in casting?
- 1, in the absence of special requirements, the most important thing is that the price is cheap.2, pig iron castings quenching process requirements are not high. You can do it by hand.3, pig iron casting hardness is very large, can meet many requirements.4, pig iron castings, high temperature resistance is relatively strong. Like stoves are pig iron castings.5, pig iron casting plasticity is very bad, but in some experiments, but use this weakness to improve the sensitivity of the experiment.Wait
- Q: Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!
- Valve sand core mold drying is not in place, excessive water content
- 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: How to solve casting defect casting?
- Different defects, different solutions, some shortcomings, the current domestic level can not be resolved
- Q: How can the casting be free of trachoma?
- 2, pouring temperature should be enough, otherwise the sand can not float up;
