Q: There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump: German winter three step mirror polishing 2013 new processYou can free proofing!

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's the effect of casting copper?: Copper is one of the main corrosion resistant alloys. When the mass fraction of copper in cast iron is from 0.25% to 1%, the corrosion resistance of copper in the industrial atmosphere can be obviously increased. But copper has very little corrosion resistance in lye or salt solution.Copper can increase the flowability of molten iron and improve its casting ability remarkably.Copper can increase the coercive force and residual magnetic force, but the permeability is not affected.Combined use of copper with other alloy elements, such as copper chromium, copper chromium molybdenum, copper molybdenum, copper manganese, copper vanadium, can achieve greater results.

Q: Casting parts need to be subjected to the kind of heat treatment after the weldment is finished: 1, gray cast iron: General graphite annealing, to be heat treatment annealing, surface hardening etc.; ductile iron can be various: annealing, normalizing, quenching and isothermal quenching, surface treatment, chemical heat treatment.2. Pouring liquid metal into the casting cavity which adapts to the shape of parts. After cooling and solidification, the casting method is called casting. Castings obtained by casting are called castings. Casting structure design: ensure the working performance and mechanical performance requirements, consider the technical requirements and performance of alloy casting casting casting structure, casting structure design is reasonable or not, the casting quality, productivity and cost has a great influence.3. Heat treatment is a metal hot working process in which the material is in solid state by means of heating, heat preservation and cooling to obtain desired microstructure and properties

Q: Domestic large steel castings factory which is better, recommend!: Do the casting manufacturer of large steel castings, Hunan Jinsha heavy industry science and technology limited company, heard that their professional only more than 1 tons of steel castings, anyway, 150T just big, the company won a lot of foundry industry patents should be good. At least spend money on research and development, then the quality should be all right.

Q: Selection of hydraulic press is the casting parts and steel plate welding, how to choose?: Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.

Q: My parts complex, machining costs are relatively high, so want to cast, but the surface needs anodizing, what material will be better?: Yes, the cast aluminium is polarized and gray, but the key problem is to guarantee the quality of the aluminium casting, and the quality of the other aluminium casting is not good.

Q: Why should pig iron be used in casting?: Popular name is called pig iron, in fact, is a kind of cast iron without treatment, after casting, in iron elements to add other elements to improve casting performanceIt mainly improves the fluidity, reduces the melting point and reduces the shrinkage.Usually pure iron and cast iron at the eutectic point (about 4.7% carbon content) can be used for castingThere are many kinds of cast iron, usually grey cast iron, ductile iron and vermicular graphite iron......

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: How to solve casting defect casting?: Different defects, different solutions, some shortcomings, the current domestic level can not be resolved
