- Q: There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump
- Use the vibrator to polish the material: the high aluminum porcelain 4cm (with a polishing agent that has an automatic mending function), you go find this polish,
- Q: Explain the heat treatment effect of casting parts, forging parts and welding parts
- 2 improve the crystal structure, enhance the formation and stability of spherical carbon crystal;Forgings are generally stress bearing members, and most of them are made of high strength medium carbon steel (alloy), which is formed by forging and fine crystalline. After the shell is annealed or quenched and tempered, the mechanical properties of the shell are more superior, and it has better strength and better elasticity;Welding materials.
- Q: What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?
- Please consider the following points:1, batch: if the product batch is very large, casting will certainly have advantages, cost sharing will be very low. If less, it is recommended to use weldments.2. Reinforcement structure: if the structure is relatively simple, it is recommended to use welded parts, complex, preferably casting.
- 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: Casting parts have poor surface finish. What sand is used to make them?
- V casting, EPC, precision casting of the surface is good.
- Q: After reaming, the roughness can reach several levels, that is to say, the sample.Casting parts in rocker arm drilling, reaming, roughness, block. After reaming, the roughness can reach several levels, that is to say, the sample.
- The finish of reaming depends on the material and the sharpness of the reamer, as well as the speed and speed of the top and bottom. Marine machine tool
- Q: Does anyone know how to make precise casting parts for aerospace or manufacturers of single and small quantities of automotive parts and components, mainly in Beijing, Tianjin and Tangshan?
- List of China's military enterprises list of ten major military groupsChina Nuclear Industry Construction Group CorporationChina Aerospace Science and Technology CorporationChina Aerospace Science and Engineering CorporationChina Aviation Industry CorporationChina Aviation Industry Corporation IiChina State Shipbuilding CorporationcsicChina North Industries Group CorporationChina South Industries Group CorporationChina National Nuclear CorporationKey military enterprisesShipbuilding industry:China State Shipbuilding Corporation (South ship group), (China Shipping Group)China Shipbuilding Industry Corp (North Ship group), (China Shipbuilding Industry)Guangzhou Shipyard International Limited by Share Ltd (GSI)Jiangnan Heavy Industry Limited by Share Ltd (Jiangnan Heavy Industry)Nuclear industry:China National Nuclear Corporation (CNNC)China Nuclear Industry Construction Group Corporation
- Q: As shown, how do I achieve the tightness test of this product, and achieve industrial production? Seek expert advice.
- Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment
- Q: When there is no flaw detection for large casting parts, is there any crack inside?
- According to the industry standards, within the scope of the standard requirements to determine whether the product is qualified
- Q: How to solve casting defect casting?
- Different defects, different solutions, some shortcomings, the current domestic level can not be resolved
