Rolled Steel Media Grinding Ball with Top Quality Steel as Raw Material for Mines and Cement Plant

Q: Why does the precision casting factory not usually make iron castings?: The so-called precision parts is the size, roughness requirements of the piece. Cast iron parts generally do not reach the accuracy.

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: It is generally said that cast iron is re smelted by pig iron. My question is..:1 pig iron for melting iron, is directly cast into products (such as bed cover, etc.); or that is just the first pig iron smelting iron casting, such as to cover, bed and other products, will once again cast iron melt to casting?2, there are many castings to the engine. Are these castings made by the engine manufacturer themselves or bought by others?There is no need to answer all. Thank you！！！: The molten iron (molten iron, scrap steel, scrap casting, iron alloy) is melted into cast iron by means of an electric furnace or cupola, and is poured into a casting.

Q: In theory, which is more expensive, forging parts or casting parts?: Compared with the price, the product with the same simple structure eliminates the material factorsThe forgings must be more expensive

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's the density of the cast iron? The density is thin and the density is thin: Generally cast iron thick place, density is empty, thin place density a little more.

Q: How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness: Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.

Q: What foundry factories are used in the casting parts of China's major automobile manufacturers?: Tangshan Yongding automobile spare parts factory also give a lot of supply, casting factory of Tangshan n to the car enterprises casting wheel gearbox etc.The team of casting experts welcome you to ask questions and accept questions!

Q: Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?: Usually manual molding optional CT11 class, ordinary machine modeling optional CT10 class, high pressure molding should reach CT9 level. The tolerances on the wall thickness of the casting are comparable to those of other dimensions of the same casting.

Q: The difference between sheet metal and casting parts: Casting parts are made by casting (followed by a variety of processing), the shape can be simple, can also be very complex, usually large parts, as a base, bed, work table, and so on, good seismic performance.
