Casting Grinding Ball Of Mining Machinery Ball Mill with High Hardness

Q:How to improve the surface roughness of casting parts?: One is to improve the accuracy of the model; the two is to improve the molding sand mesh. How much is the other relationship?.

Q:Why do casting parts have air holes?: Cangshan Qiao hidden his answer is quite comprehensive, you can try using inert gas to reduce air cover

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 is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?: For the nodular cast iron, the hardness, strength and wear resistance are improved, such as used in the manufacture of automobile, tractor, diesel engine crankshaft, connecting rod and other important parts. A normalizing and hypereutectoid ball annealing before, can eliminate the mesh two cementite spheroidizing annealing, to ensure that all spheres of cementite. Annealing is a metal heat treatment process, which means the metal is slowly heated to a certain temperature, sufficient for a long time, and then cooled at an appropriate speed. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize size, reduce deformation and crack tendency, refine grain, adjust microstructure and eliminate tissue defects. Its purpose: (1) reduce hardness and improve machinability; (2) eliminate residual stress, stabilize size, reduce deformation and crack tendency; (3) refine grain, adjust microstructure and eliminate tissue defects. In production, annealing process is widely used.

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:For example, casting parts contain many holes, inclusions and other defects, the size and the number of holes exceed which limit is not qualified: According to different casting process and parts materials, each has relevant standards, can be found online;

Q:How to calculate the price of casting parts?: According to the complexity of the workpiece, material and casting requirements and process yield

Q:What do you mean by "proofing" in the casting? Do you charge for the proofing?: Die die must charge, wood cheap, expensive aluminum mold

Q:How to distinguish the forging parts and casting parts accurately: To distinguish from the use of materialsForging materials are mainly made of carbon steel and alloy steel of various components, followed by aluminum, magnesium, titanium, copper and their alloys. The original state of the material is rod, ingot, metal powder and liquid metal. The materials needed for casting are mostly metal, wood, fuel, molding materials and so on. In contrast, the forging parts rarely produce dust, harmful gas and noise, etc., and play a more obvious role in environmental protection. Of course, because of this, the price of forged parts on the market is higher than that of castings.

Q:Casting blank in the cooling process to release a large amount of heat energy, what can be recycled?: Casting, do not need to provide a rough casting foundry drawings, according to your chart will put foot margin in the processing needs of the surface, the rest of the size can be found according to the mechanical design manual and manual casting.
