Definition Of Flange Ring Heavy Steel Forgings Alloy Steel Flange Fittings Forged Flange

1. . Description of Flange

Flange and stainless steel flange is mainly applied to the petroleum and natural gas pipeline joints and chemical industry, nuclear power, pressure vessel industry etc..

We are a professional forging flanges and ring forgings provider, providing all flange forging, engineering mechanical ring forgings, base of the excavator, rotary bearing seat, wind power flange, pressure vessel flange. Free forging and rolling ring processing. Main products: all kinds of material flange (including carbon steel flange and stainless steel flange, dual phase steel flange...); also can grind machining the ring diameter of 6 meters, single weight of 20 tons of all kinds of ring forgings (including: Excavator base, mixer truck rolling, wheel mechanical ring forgings; pressure vessel for flange, wind power flange); also can according to customer drawings according to the required processing.

2. Flange of specifications

The forging process generally consists of the following steps, namely using high quality material, billet heating, forming, cooling after forging. Process for forging the free forging, forging and forging membranes. According to the quality of production, size, number of batch production of different forging method.
Low productivity of free forging, machining allowance, but simple tools, general big. Therefore, it is widely used in forging of a simple shape of single and small batch production of forgings. Free forging equipment of air hammer, steam air hammer and hydraulic press, respectively, and suitable for small production of large forgings. Forging of high productivity, simple operation, easy to realize mechanization and automation. Die forging of high precision, small machining allowance, fibrous tissue distribution of forgings is more reasonable, can further improve the service life of parts.
The basic process of free forging, forging, forging shape by some basic deformation processes will be gradually forged into a blank. The basic process of forging is upsetting, stretching, punching, bending and cutting etc..
The 1 upsetting upsetting to the original billet along the axial forging process, the height reduction, cross section increases. This process is commonly used in forging gear blanks and other disc shaped forgings. Upsetting for all local upsetting and upsetting two.
2 long pulling length is to increase the length of the billet, the cross section of the forging process is reduced, usually used to produce the shaft parts blank, such as lathe spindle, connecting rod, etc..
3 punching punch forging processes out through holes or blind holes in the blank.
4 the forging process of a blank to form a certain angle or shape.
5 twist makes a part of the billet to rotate a certain angle relative to the other part of the forging process.
6 cutting head segmentation or the removal of blank forging process.
die forging
The model of forging die forging, the blank is heated placed in fixed on the die forging equipment in forging.
The basic process of die forging process of forging: blanking, heating, pre forging and finish forging, punching, trimming, hardening, shot peening. The commonly used technology for upsetting, stretching, bending, punching, forming.
The common forging equipment commonly used equipment, forging die forging hot forging press, forging and friction press etc..
Common ground is told, flange forging for better quality is generally through the production of forging, fine crystal structure, high strength, of course, the price is expensive.
Whether it is still belong to the casting flange forging flange flange manufacturing method commonly used, asked to see the need to use the strength of components, if the demand is not high, you can also use turning flange.
