EN-GJS 400-15 / 500-7 Ductile Iron Bars | Simbi yeSpheroidal Graphite
Nhanganyaya yeChigadzirwa
EN-GJS 400-15 / 500-7 Ductile Iron Bars zvigadzirwa zvesimbi zvakagadzirwa zvinoenderana nezvinodiwa neEuropean, zvakagadzirirwa kushandiswa zvinoda simba rakawanda, ductility yakanaka, uye michina yepamusoro. Mabhara aya anogadzirwa ne spheroidal graphite microstructure, iyo inopa hunhu hwakanaka hwekudhonza uye kuramba kukanganiswa, zvichiita kuti ave sarudzo inoshanda zvakasiyana-siyana yekushandiswa kwechimiro uye michina.
Nhevedzano yeEN-GJS inonyanya kufarirwa muEurope nekuda kwekupa mhando dzakasiyana dzesimba uye kurebesa. EN-GJS 400-15 ine ductility yakanaka uye kusimba, nepo EN-GJS 500-7 ichipa simba rakawanda uku ichichengetedza kuchinjika kwakakwana. Aya masimbi esimbi anobatsira zvikamu zvinogara zvichidzokororwa, kudedera, kana kukanganiswa zvine mwero. Kugona kwawo kugadzira kunoita kuti akwanise kushandiswa pakukwesha uye pakupedzisa nemazvo.
- 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:
| ASTM A536 | MUNA 1563 | ISO 1083 | JIS G5502 |
| 60-40-18 | EN-GJS-400-15 | GGG40 | FCD400 |
| 65-45-12 | EN-GJS-450-10 | - | FCD450 |
| 80-55-06 | EN-GJS-500-7 | GGG50 | FCD500 |
| 100-70-03 | EN-GJS-600-3 | GGG60 | FCD600 |
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.

Zvishandiso zveChigadzirwa
EN-GJS ductile iron bars dzinoshandiswa mumaindasitiri akasiyana-siyana, anosanganisira:
>Zvikamu zvemakanika zvakaita semagiya, mapuru, uye shafts
>Zvikamu zvechivakwa mumichina yeindasitiri
>Matumbu evharuvhu uye ma hydraulic manifolds
>Mabhureki emotokari uye dzimba dzekusiyanisa
>Zvishandiso zvekusimudza nekugadzira
>Zvikamu zvemichina yekurima
