Introduction to the rolling flange and its manufacturing industry

　　Introduction to the rolling flange is used to cut the strip and then roll into a circle process called roll system, and more for the production of some large flange. Rolling after the success of the welding process and then flatten, then the waterline and bolt hole.

　　Large coil flange is a flange in the machinery industry in general use and promotion, get the user's praise and favor. Large volumes of flange on a wide range of uses, use range are determined in accordance with different characteristics, used for medium conditions are relatively mild, such as low non clean compressed air, low pressure circulating water and its advantages are relatively cheap price.

　　In the machinery industry, many manufacturers use large volumes of flange (also can be said is to strengthen ring) just as connection or support and so on, said to be used (flat) strip directly in large volumes of flange equipment direct volume required ring can be made. The processing technique of saving, labor saving, and material saving, greatly reduces the cost.

　　Coil manufacturing industry is the production of the first plate cut into the appropriate strip, the length of the length according to the specifications of the large flange. And then made into a circle with the coil ring machine, with the electrode to weld the interface firmly. Then press the flattened, and then lathe processing waterline, chamfering process, finally with indexing disc with a drilling machine processing of bolt hole drilling.
