Casting flanges and casting flanges are often put together to compare, but do you understand the difference and process of casting flanges and casting flanges? Today we will take you to understand the difference between casting flange and forging flange.
First of all, casting flange, casting out of the flange, blank shape and size is accurate, a small amount of processing, low cost, but there are casting defects (porosity. Cracks. Inclusions); casting internal organization streamline poor, forging flange is generally lower than the casting flange carbon content is not easy to rust, forging streamline good, the organization is denser, the mechanical properties are better than the casting flange.
The advantage of casting is that you can make a more complex shape, and the cost is relatively low; The forging advantage is that the internal organization is uniform, there is no casting in the porosity, inclusions, and other harmful defects; from the production process to distinguish between casting flange and forging flange, such as centrifugal flange belongs to one of the casting flange.
Centrifugal flange belongs to the precision casting method of production flange, this kind of casting than ordinary sand casting organization to be much finer, the quality is improved a lot, not easy organization loss, porosity, trachoma, and other problems.
The forging process is generally composed of the following procedures, namely, selecting high-quality billets for discharging, heating, forming, and cooling after forging. The forging process methods are free forging, die forging, and tire film forging. Production, according to the size of the quality of forgings, the number of production batches to choose a different forging method.
Die forging is known as model forging, the heated billet placed in the forging equipment fixed in the die forging forming.
Commonly speaking, forging flange quality is better, generally produced by die forging, crystal organization is fine, high strength, of course, the price is also more expensive.
Whether casting flange or forging flange belongs to the flange common manufacturing methods, see the need to use the strength requirements of the components, if the requirements are not high, you can also choose the turning system flange.
