Nhanganyaya yeChigadzirwa
High Strength Ductile Iron Bar chinhu chepamusoro-soro chakagadzirwa zvakanangana nezvikamu zvemakanika zvinoda kusimba uye kushanda. Chinozivikanwawo seSG Iron kana Spheroidal Graphite Iron, chinhu ichi chinosanganisa kuchinjika kwesimbi nekuumbwa kwayo zviri pedyo nesimbi. Nesimba rayo rakasiyana, kugona kwayo kugadzira michina zvakanaka, uye kugona kwayo kudzikamisa simbi, ductile iron bar yave sarudzo inofarirwa kune akawanda mashandisirwo emaindasitiri, kusanganisira masisitimu ehydraulic, zvikamu zvemuchina, uye zvikamu zvemagetsi zvinotumira simba.
Kusiyana nesimbi yegrey, simbi ine ductile ine graphite yakaita sedenderedzwa, iyo inowedzera simba rayo rekudhonza uye kuramba kubatwa. Iyi process ye microstructure inoita kuti igare kwenguva refu mumamiriro ezvinhu anorema, zvichiita kuti ive yakakodzera kune zvese zvinhu zvisingachinji uye zvinoshanduka. Ductile iron bars inowanikwa mudhayamita dzakasiyana uye inogona kupihwa mumamiriro ezvinhu akaomarara kana akagadzirwa nemazvo kuti ienderane nezvinodiwa zvakasiyana zvemaindasitiri.
- simbi dzakapfava dzinogadzirwa zvichienderana nezvinodiwa nenyika dzese. Mhando dzesimbi dzinoshandiswa zvakanyanya dzesimbi dzakapfava dzinoratidzwa nenzira dzakasiyana zvichienderana nenyika dzakasiyana uye zviyero.
Zvinotevera ndizvo zvinowanzoshandiswa mu ductile iron steel grades (magiredhi) pasi pemaitiro akasiyana-siyana akafanana:

Tsananguro yeChigadzirwa
Ductile iron bar chinhu chinovandudza hunhu hwayo hwemakanika nekuwedzera zvinhu zvinosanganisa simbi zvakaita semagnesium kana cerium kuti zvigadzire simbi kuti igadzire graphite kuita chimiro chedenderedzwa. Panyaya yemakemikari, zvikamu zvikuru zvesimbi iron, kabhoni, silicon, pamwe nemanganese, phosphorus, sarufa nezvimwe zvinhu. Kuwedzera zvinhu zvinosanganisa simbi zvakaita semagnesium kana cerium kwakakosha, izvo zvinokurudzira kuumbwa kwechimiro chedenderedzwa mugraphite.
Ductile iron rods dzinowanzo shandiswa munzvimbo dzakadai semagiya nezvikamu zveshaft mukugadzira michina, macrankshaft nematanda ekubatanidza muindasitiri yemotokari, mapaipi nezvikamu zvekuvaka mumunda wekuvaka, zvikamu zvehydraulic mumichina yekuvaka, uye mavharuvhu nemidziyo yepombi muindasitiri yesimba.
