3.Feature of Low Breakage Rate Grinding Media Ball Made in China with the Top Quality Steel and High Hardness
1) In general, grinding steel ball has high hardness: surface hardness to 58-65 HRC, volume hardness of 56-65 HRC
2) impact toughness high: impact toughness more than 12 J / cm2.
3) broken rate is low: the actual broken rate is not higher than 0.5%.
4) loss of grinding forged steel ball round rate is low.
- Q: What's the effect of casting copper?
- Riga. Copper is copper components, promote the graphitization of the copper element, make dense tissue, and to refine and improve the uniform distribution of graphite, which can reduce the chilling tendency of the cast iron, but also can promote the formation of pearlite, has a favorable effect on the section sensitivity. Copper has the tendency to strengthen cast iron, ferrite and pearlite, so it can increase the strength of cast iron. The tensile strength and bending strength of cast iron almost increase with the amount of copper in it, especially in low carbon cast iron.
- 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 kind of casting process is used for cast iron parts? And what are the cast steel parts adopted?
- The main content of red sand table (Institute of soil science, China) silica 79.4%. three 1.48%. three 10.55%. two aluminum oxide iron oxide, calcium oxide 0.85%. Magnesium Oxide 0.52%. 1440. refractory mud 3.06% LOI 1.98% red sand with high silicon content, permeability is strong, durable, high refractoriness, good angle, low moisture content, less mud the casting finish is high, the basic requirements of sand should meet the following requirements: Casting of high purity and cleanliness, with silica sand as an example, iron sand SiO2 content of more than 90%, the big steel casting requests the SiO2 content of more than 97%; the high refractoriness and thermal stability; the suitable particle the shape and particle composition; it is not easy to be wetted by the liquid metal; cheap. The particle shape and composition of casting sand particle shape and particle composition permeability properties such as mobility, sand compaction, permeability, strength and resistance to liquid metal effects, is an important indicator of the quality of casting sand.
- Q: the parts of the threaded hole is casting, casting the hole directly, and then tapping or casting, and then punch 10When the casting is ready, punch it again before tapping it Is the hole casting good or is it punched and tapped on the drilling machine after casting?
- There are several casesThe first hole with a diameter of less than 4MM is generally not done, or as a hole location only for a period of less than 10MM.Second for the big hole, some of the reasons for the holding force, we must increase the slope, direct tapping is unlikely, so it still needs post-processingThird for products with high tightness requirements, some cores need to be made even if they are very small, so they can be tapped directlyFourth, some due to technical requirements, regardless of the size of each other's requirements must be made, there is no wayThe above methods are common, and they will encounter many small problems in actual production.
- Q: The cause of fracture and why there is no toughness
- This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.
- Q: What are the causes of pitting on the surface of a precision casting?
- The quality of the shell surface is out of order. Or shot blasting out of question.
- Q: How to distinguish the forging parts and casting parts accurately
- Distinguish from performance:The processing performance of forged parts is higher than that of the same material. The forging parts are compact and have good mechanical properties, but the casting parts may have sand holes, holes, shrinkage holes and other defects, and their mechanical properties are inferior to those of forgings. At the same time, forging processing can ensure the continuity of the metal fibrous tissue, fibrous tissue to forging and forging shape consistency, metal streamline integrity, can ensure the parts with mechanical properties and long service life good.
- Q: Why do casting parts have air holes?
- First, from the source, tools, raw material drying, in the process of melting into the reaction gas, another influence is pouring process, such as high temperature solidification gas dissolved too much after not excluded. The method can adjust the pouring temperature properly, control the source of gas (drying and controlling the inoculant, especially the content of magnesium), and add cooling iron to change the solidification mode. It depends on what kind of casting you are. You can't make it clear at once. And molding sand relationship is mainly water content and permeability, brush coating resin content.
- Q: Why should pig iron be used in casting?
- Not necessarily is iron, steel, stainless steel, aluminum, copper can be cast iron, is cheaper, and better properties of cast out, for example, is not easy to rust, high strength, easy processing and so on, and is the only iron iron cast out, it is not necessarily the raw pig iron, plus some other material
- Q: What are the general technical requirements for casting parts?
- What kind of casting do you want to know? Copper parts, iron pieces, aluminum pieces??? Their casting conditions are different.
