Zvakanakira ductile iron mapaipi

Ductile iron pombizvemhando yepamusoro kupfuura pombi dzakakandwa dzesimbi. Girafu musimbi yakajairika iri mumapepa uye ine simba rakaderera. Saka simba rakajairwa resimbi yakakandwa ishoma, brittle. Iyo graphite mu graphite cast iron ine denderedzwa, yakaenzana nekuvapo kweakawanda spherical voids musimbi yakaumbwa. Kupesvedzera kwe spherical void pane simba re cast iron idiki pane iyo flake void, saka kusimba kwe ductile iron pombi yakakwira zvakanyanya kupfuura yeyakajairika simbi yakakandwa.

Zvakanakira zve ductile iron pombi application mupombi yekupa mvura:

1. Nokuti ductile iron pombi inotora flexible joint, basa rekuvaka rinonyanya nyore, rinogona kuvandudza kushanda kwekuvaka, kuvandudza mamiriro ekuvaka, kuderedza mari yekuvaka, uye yakawanda yekubatanidza inotora rubber ring connection, nyore kushanda, inogona kupfupisa nguva yekuvaka, kuderedza mari yekuvaka.

2. Nekumanikidzwa kwemvura yakakwira, kuramba kune mutoro wekunze uye kuenderana nekuchinja kwemamiriro e geological, pombi ine zvakanakira simba rakakura, kusimba kwakanaka, kusimba kwemarara, flexible interface iri nyore kuisirwa, yakasimba seismic resistance, kuderera kwekushanda kwekushanda, inogona kuiswa kune geological urombo chikamu uye mhiri kwemugwagwa, pasina kuwedzera kugadziridzwa kwesimbi pombi, pamwe chete neiyo yakasimba corrosion kumahombekombe, inogona kuiswa mushonga we saline kumahombekombe. Parizvino, inoshandiswa zvakanyanya muinjiniya yepasi pevhu. Mapurojekiti akakura ekuisa pombi anogona kuratidza zvakanakira kuisirwa zviri nyore uye kushomeka kwevashandi.

3. Iyo nodular cast iron pipe ine yakanaka yekuisa chisimbiso uye haisi nyore kudonhedza, iyo inogona kuderedza kudonha kwehuwandu hwepombi network uye kuderedza mutengo wezuva nezuva wekuchengetedza pombi network.

Graphite mune nodular cast iron iri muchimiro che spherical. Saizi yegraphite ndeye 6 ~ 7. Panyaya yemhando, iyo spheroidization giredhi yenodular cast iron pombi inofanirwa kudzorwa se1 ~ 3 giredhi spheroidization rate >. =80%. Nokudaro, iyo mechanical properties inovandudzwa zviri nani. Ductile iron pombi vagadziri vanoratidza kuti mushure mekuvhara ductile iron pombi, iyo metallographic chimiro ndeye ferritic ine diki mwenje mwenje. Zvakanaka mechanical properties.
