Five kinds of flange processing process steps

1, casting flange processing process.

The selected raw materials steel into the medium frequency electric furnace melting, so that the steel temperature of 1600-1700 ℃; the metal mold preheated to 800-900 ℃ to maintain a constant temperature; start the centrifuge, the steel into the preheated metal mold; castings naturally cooled to 800-900 ℃ to maintain 1-10 minutes; cooling with water to close to room temperature, take off the mold and remove the casting.

2、Forging flange processing process.

The forging process is generally composed of the following processes, namely, selecting high-quality billets, heating, forming, and cooling after forging. The forging process methods are free forging, die forging and film forging. When producing, according to the size of the forging quality, the number of production batch to choose different forging methods.

Die forging parts with high dimensional accuracy, small machining allowance, forgings with a more reasonable fiber tissue distribution, can further improve the service life of the parts

.

The basic process of free forging: In free forging, the shape of the forgings is forged into the billet gradually through some basic deformation processes. The basic processes of free forging are upsetting, drawing, punching, bending and cutting, etc.

3、Die forging process.

The basic process of die forging The process of die forging: material, heating, pre-forging, final forging, punching with skin, cutting edge, tempering, shot blasting. Commonly used processes are upsetting, drawing length, bending, punching, forming.

4、Cutting flange processing technology.

In the plate directly cut out the flange of the inner and outer diameter and thickness of the disk with the amount of processing, and then bolt holes and waterline processing. The flange produced in this way is called cut flange, the maximum diameter of such a flange to the width of the plate is limited.

5, rolled flange processing technology.

Cut strips with the plate and then rolled into a round process called rolling, mostly used in the production of some large flange. After the successful rolled welding, and then flattened, and then the waterline and bolt hole processing technology
