Kukandira simbiyakashandiswa zvakanyanya mumaindasitiri uye muchina kubva payakagadziriswa yemazuva ano. Kunyangwe munguva dzazvino, masimbi esimbi achiri kuita basa rakakosha mumarori, njanji dzinotakura zvinhu, matirakita, michina yekuvaka, inorema basa midziyo ... nezvimwe. Simbi yakakandwa inosanganisira grey iron, ductile iron (nodular), white iron, compacted graphite iron uye simbi inogoneka. Grey iron yakachipa kupfuura ductile iron, asi ine simba rakaderera uye ductility pane ductile iron. Grey iron haigone kutsiva iyo kabhoni simbi, nepo ductile iron inogona kutsiva iyo kabhoni simbi mune imwe mamiriro ezvinhu nekuda kwekusimba kwakanyanya, kusimba kwegoho uye kurebesa kweiyo ductile iron.
Carbon steel castingsanoshandiswa mune akati wandei maindasitiri ekushandisa uye nharaunda zvakare. Nemagiredhi avo mazhinji, kabhoni simbi inogona kudziyirwa-kunatsiridza goho rayo uye kusimba kwesimba, kuomarara kana ductility kune izvo mainjiniya ekushandisa zvinodiwa kana zvinodiwa zvemuchina. Mamwe magiredhi akaderera esimbi yakakandwa anogona kutsiviwa ne ductile iron, chero bedzi simba ravo rekusimba uye kureba zviri pedyo zvakakwana. Pakufananidza zvimiro zvavo zvemuchina, isu tinogona kunongedzera kune iyo simbi yakatarwa ASTM A536 ye ductile iron, uye iyo ASTM A27 yekabhoni simbi.

Ductile iron casting componentsIva nekuita kurinani kwekuvhunduka kupfuura kabhoni simbi, nepo kabhoni simbi castings ine zvirinani weldability. Uye kune imwe nhanho, iyo ductile iorn castings inogona kunge iine mamwe maitiro ekupikisa kupfeka uye ngura. Saka iyo ductile iron casting inogona kushandiswa kune dzimwe dzimba dzepombi kana masisitimu ekupa mvura. Nekudaro, isu tichiri kuda kuita matanho ekudzivirira kubva pakupfeka uye ngura. Saka kazhinji kutaura, kana iyo ductile iron ichigona kuzadzisa zvaunoda, iyo ductile iron inogona kuve yako yekutanga sarudzo, pachinzvimbo chekabhoni simbi yekukanda kwako.
