Ductile Iron Sand Kukanda Centrifugal Pump Housing kubvaChina FoundryneOEM Tsika uye CNC Machining Services.
Cast iron isimbi-carbon cast alloy ine zvimwe zvinhu zvinogadzirwa nekunyungudutsa simbi yenguruve, zvimedu, uye zvimwe zvinowedzera. Pakusiyanisa kubva kusimbi uye simbi yakakandwa, simbi yakakandwa inotsanangurwa seyakakandwa alloy ine kabhoni yemukati (min 2.03%) inovimbisa kusimba kwechikamu chekupedzisira neshanduko eutectic.
Zvichienderana nekutsanangurwa kwemakemikari, simbi dzakakandwa dzinogona kunge dzisina kusanganiswa kana kusanganiswa. Huwandu hwema iron alloyed hwakapamhama, uye hune huwandu hwepamusoro hwezvinhu zvakajairika, sesilicon nemanganese, kana zvimwe zvinowedzerwa, zvakaita senickel, chromium, aluminium, molybdenum, tungsten, mhangura, vana-dium, titanium, pamwe chete. vamwe. Kazhinji kutaura, simbi yakakandwa inogona kukamurwa kuita grey iron, ducitle iron (nodular iron), white cast iron, compacted graphite iron uye malleable cast iron.

Ductile cast iron, iyo inonziwo nodular cast iron, spheriodal graphite cast iron kana kungoti SG iron kwenguva pfupi, inomiririra boka resimbi yakakandwa. Nodular cast iron inowana nodular graphite kuburikidza ne spheroidization uye inoculation kurapwa, iyo inobudirira inovandudza ma mechanic properties yesimbi yakakandwa, kunyanya plastiki uye kuoma, kuitira kuti uwane simba rakakwirira kudarika carbon steel.
Ductile iron castings ine zvirinani kunyura kuita pane 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.
Ductile iron haisi chinhu chimwe chete asi chikamu cheboka rezvinhu zvinogona kugadzirwa kuti zvive nehuwandu hwezvinhu kuburikidza nekutonga kwe microstructure. Izvo zvinowanzotsanangudza hunhu hweboka iri rezvinhu chimiro chegraphite. Mune ductile irons, iyo graphite iri muchimiro chemanodule kwete maflakes sezvairi mugrey iron. Iyo yakapinza chimiro chemaflakes e graphite inogadzira kushushikana pfungwa mukati mesimbi matrix uye yakatenderedzwa chimiro chemanodule zvishoma, nekudaro kuvharidzira kusikwa kwekutsemuka uye nekupa iyo inosimudzira ductility inopa alloy zita rayo. Saka kazhinji kutaura, kana iyo ductile iron ichigona kuzadzisa zvaunoda, iyo ductile iron inogona kuve yako yekutanga sarudzo, pachinzvimbo chekabhoni simbi yekukanda kwako.
