Stainless steel casting processing has a wide range of applications, mainly through stainless steel casting processing materials with different shapes formed after processing. The processing flow of stainless steel casting and processing profiles is mainly casting, and the following stainless steel casting processing--Blue Sky Precision Alloy Foundry For you to introduce in detail the casting process in stainless steel casting process:

The casting process in stainless steel casting process is mainly a method of melting and casting a molten material into a product at a high temperature. In fact, the production is complicated, but it is not difficult to use the machine during processing. The production process mainly achieves the purpose of casting by changing some parameters, from the melting atmosphere, melting temperature and cooling conditions to ensure the efficiency of production, etc., but in the process of cooling, the temperature inside is often caused by the formation of voids inside the product. We call it shrinkage. However, there are fixed equipments for casting at present, and we can adjust the conditions to meet our needs, so the castings produced today are very good.

Stainless steel casting and precision casting refers to the process of cutting, folding, bending and welding of stainless steel casting processing by the performance of stainless steel casting processing, and finally obtaining the process of stainless steel casting and processing products required for industrial production. A large number of machine tools, instruments, and stainless steel casting processing equipment are required in the casting process. The following blue sky precision alloy foundry, for you to introduce, in the stainless steel casting process precision casting process should pay attention to what problems, as follows:

1. After hot rolling, annealing, pickling and descaling, the surface of the steel plate is a dull surface, a bit rough, and should not be considered as a damaged part.

2. After cold rolling, annealing, descaling, and finally light rolling with a matte roll, this is the most commonly used in construction applications, except for the last mild cold rolling with a polishing roll after annealing and descaling, other processes and 2D is the same, the surface is slightly radiant and can be polished; Bright Annealing: This is a reflective surface that is rolled by a polishing roll and finally annealed in a controlled atmosphere. Bright annealing still maintains its reflective surface and does not produce scale. Since the oxidation reaction does not occur during the bright annealing process, it is not necessary to perform pickling and passivation treatment.

3. Polished surface processing: the surface is uniformly ground, the abrasive grain size is 80~100'; the matte surface is polished, and the surface has uniform straight lines. Usually, the abrasive belt with a particle size of 180~200 is thrown once on the 2A or 2B board. Grinded.

4. Unidirectional surface processing, low reflectivity, this surface processing may be the most versatile in architectural applications. The process steps are first polished with a coarse abrasive and finally with an abrasive having a particle size of 180.

Stainless steel casting and casting castings preferably have a dimensional accuracy of 5 名义 of nominal size and a roughness level of Ra 0.8-3.2 um. Thereby greatly reducing the workload of subsequent machining. In the case of near net shape and even net shape, machining is almost completely eliminated.

The castings have superior mechanical properties and low molding costs:

Due to the superiority and stability of the process itself, the mechanical properties of the casting can be maintained at a high level.

Lost wax precision casting is particularly suitable for situations where the shape of the structure is complex. A properly designed single casting can sometimes replace multiple parts of the equipment, which can include ordinary casting, machining, stamping, forging, injection molding, sheet metal, and the like. At the same time, in view of the strong flexibility of the process, the molding is easy, the weight of the parts can be significantly reduced, thereby greatly reducing the processing cost. In addition, it is also very conducive to saving and environmental protection.

Wide range of material adaptability:

Silica sol lost wax precision casting is suitable for most casting alloys, including various cast iron, carbon steel, low alloy steel, tool steel, stainless steel casting, heat resistant steel, nickel alloy, cobalt alloy, titanium alloy, bronze, brass , aluminum alloy, etc. And its overall processing effect is relatively stable, especially suitable for materials that are difficult to forge, weld, and machine.

Excellent production flexibility:

It is very suitable for high-volume, small-volume, and even single-piece production, sometimes without even the difference in production costs. There is no need for very complicated machinery and the mold processing scheme is flexible.
