EN-GJS 400-15 / 500-7 Ductile Iron Bars | Tšepe ea Spheroidal Graphite
Selelekela sa Sehlahisoa
EN-GJS 400-15 / 500-7 Ductile Iron Bars ke dihlahiswa tsa tshepe e entsweng ka tshepe e sebetsang hantle tse entsweng ho latela maemo a Yuropa, tse etseditsweng ka ho kgetheha ditshebediso tse hlokang matla a hodimo, bokgoni bo botle ba ho dutla, le bokgoni bo phahameng ba ho sebetsa. Ditshepe tsena di hlahiswa ka sebopeho se senyenyane sa graphite sa spheroidal, se fanang ka thepa e makatsang ya ho thaepa le ho hanyetsa tshusumetso, e leng se etsang hore e be kgetho e feto-fetohang bakeng sa ditshebediso tsa meaho le tsa mechine.
Letoto la EN-GJS le ananeloa haholo Europe ka ho fana ka mefuta e fapaneng ea metsoako ea matla le bolelele. EN-GJS 400-15 e khetholloa ka ho ba bonolo le ho tiea ho hoholo, athe EN-GJS 500-7 e fana ka matla a holimo ha e ntse e boloka ho tenyetseha ho lekaneng. Litšiea tsena tsa tšepe tse ductile li loketse likarolo tse fetang khatello e pheta-phetoang, ho thothomela, kapa ho otloa ka mokhoa o itekanetseng. Ho sebetsa ha tsona ka thata ho li etsa hore li be ntle bakeng sa ts'ebetso ea ho qeta ka ho otlolla le ka ho nepahala.
- lithapo tsa tšepe tse entsoeng ka ductile li etsoa ho latela maemo a machaba. Lithapo tsa tšepe tse sebelisoang hangata tsa lithapo tsa tšepe tse entsoeng ka ductile li hlahisoa ka litsela tse fapaneng ho latela linaha le maemo a fapaneng.
Tse latelang ke limaraka tsa tšepe tsa ductile tse sebelisoang haholo (limaraka) tlas'a litsamaiso tse 'maloa tse tloaelehileng tse tloaelehileng:
