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: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:Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!
Increase the refractoriness and looseness of core sand
Q:Casting parts, anodizing 20
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:What do you mean by "proofing" in the casting? Do you charge for the proofing?
Proofing? In the casting industry is not called proofing, proofing is generally used in the printing industry, that is, according to the customer's drawings or samples, to do a first piece, to provide customers with the inspection process to meet their requirements;In the foundry industry, providing prototypes is sometimes difficult:1, customers if the provision of mold, it would be best, at this time, sample costs are very low, and almost the same as your regular products;2, the customer does not provide the mold, but in business relationships, your factory and not very sure must take this one, it requires your leadership decision-making, is free or low cost, or by a strict process offer (of course sample);3, not all of the casting process to provide samples are difficult, like lost foam can directly make a white NC prototype, and then assembled pouring, this is her unique advantages, first cost less than the opening process and so on;If you don't understand, you can continue to question me
Q:What foundry factories are used in the casting parts of China's major automobile manufacturers?
For example Changchun FAW, under a casting, two casting and other casting plant, but there are more than half of all outsourcing in Tianjin Hebei Shandong purchase, many automobile enterprises to casting foundry.
Q:Casting parts in rocker arm drilling, reaming, roughness, block.
Not processed, do not understand your problem... There's something wrong with the drilling machine. Please call me
Q:Is the cast steel a casting part?
Cast steel is one of the casting parts that you call. The material is made of carbon steel or alloy steel, stainless steel, etc. the method is cast
Q:Can the casting part be phosphating with the phosphating solution of the pickling board?
If it is Phosphating for painting, it is not necessary, because the surface of the casting is rough and can be firmly bonded with the paint film.
Q:How to collect exothermic process of casting blank?
General Casting Factory Casting Division will be in your chart marked on shrinkage and processing margin figure (usually with red and green pen) to the patternmaker production of wood or other material mould diagram.
