Casting and forging flange flange (www.kundamfj.com)
Cast out flange; accurate blank shapes and sizes; small processing volume; low cost; but there casting defects (pores cracks inclusions.); Cast streamlined internal organization of poor (if the cutting member, streamlined worse);
Kun 达法兰 - forging flange flange is generally lower than the carbon rust casting; forging streamlined good; the organization is relatively compact; mechanical properties superior to casting flange;
Improper forging process also occurs large grains or uneven hardening crack phenomenon, forging costs than cast flange.
Forgings than casting can withstand higher shear and tensile forces.
Casting advantage is that it can come up with a more complex shape, the cost is relatively low;
Forgings advantage is that even within the organization; casting pores absent; inclusions and other harmful defects;
From the difference between the production process of casting and forging flange flange different, such as belonging to a centrifugal casting flange flange.
Centrifugal casting method of producing a precision flange flange, the more common kind of casting sand casting organization much fine, quality improved greatly, loose tissue, pores, trachoma and other issues is not easy to appear.
First, we need to understand how to produce centrifugal flanges are made; centrifugal casting making welded flange process method and product; characterized in that the product has been processed by the following process steps:
① selected raw steel into the melting furnace, the molten steel temperature reaches 1600-1700 ℃;
② metal mold preheated to 800-900 ℃ constant temperature;
③ start the centrifuge, the step ① Step ② the molten steel into the preheated mold;
④ holding the casting was allowed to cool to 800-900 ℃ 1-10 minutes;
⑤ water cooled to near room temperature, remove the casting mold release.
Main products: stainless steel flat welding flange, high-neck flange, spiral wound gasket (with inner and outer rings), graphite composite pad (packing rings, self-sealing), PTFE gasket (packing), asbestos gaskets. octagonal pad, lens pad, oval pad, tooth pad rubber gaskets, graphite packing, PTFE packing, carbonized fiber packing, high pressure asbestos rubber sheet, multi-level valve seals, rubber O-rings, a special non- Standard & seal products can produce: DN10-DN6000mm Nominal:. 0.6 ~ 63MPa Working temperature: -200 ~ 1200 ℃.
