Ductile Iron Hoobkas tau tsim txij li xyoo 2021
1. Lus Taw Qhia:
Ductile cam khwb cia hlau yog cov khoom siv hlau cam khwb cia siab uas tsim nyob rau xyoo 1950s.Nws txoj kev ua tau zoo yog ze rau ntawm cov hlau.Raws li nws cov kev ua tau zoo heev, nws tau ua tiav siv los nrum qee lub zog thiab nrog kev xav tau ntawm lub zog, toughness, thiab hnav tsis kam.Ductile cam khwb cia hlau tau tsim sai sai rau hauv cov khoom siv hlau cam thib ob nkaus xwb rau grey cam khwb cia hlau thiab dav siv.Lub npe hu ua "hloov hlau rau cov hlau" feem ntau yog hais txog cov hlau hlau.Ductile cam khwb cia hlau tau txais cov ductile graphite los ntawm spheroidization thiab inoculation kev kho mob uas zoo txhim kho cov neeg kho tshuab cov khoom ntawm cam khwb cia hlau, tshwj xeeb tshaj yog cov yas thiab toughness, yog li tau txais lub zog siab dua carbon steel.
2. Kev ua tau zoo:
Cov hlau castings yuav luag tau siv nyob rau hauv tag nrho cov kev lag luam loj, uas xav tau lub zog siab, plasticity, toughness, hnav tsis kam, thermal thiab mechanical shock resistance, siab lossis kub tsis kam, corrosion resistance, thiab dimension stability.Txhawm rau ua kom tau raws li cov kev hloov pauv no hauv kev siv, cov hlau nplaum muaj ntau qib, muab ntau yam khoom siv thiab lub cev.
3. Khoom siv:QT450-10
4. Daim ntawv thov:
Cov khoom siv hlau cam khwb cia rau cov khoom siv hauv qab, zoo li lub hau kawg rau cov menyuam nqa khoom, lub dab tshos rau cov menyuam taug kev, lub bracket rau idler
5. Muaj peev xwm ntau lawm:500-550T / hli, Automated ntau lawm kab.
6. Qhov zoo:
1) Piv nrog cam khwb cia hlau, cov hlau cam khwb cia hlau muaj qhov zoo tshaj plaws hauv lub zog.Lub zog tensile ntawm cov cam khwb cia hlau yog 60k, thaum lub zog tensile ntawm cam khwb cia hlau tsuas yog 31k.Lub zog tawm ntawm cov hlau cam khwb cia yog 40k, thaum lub cam khwb cia hlau tsis qhia lub zog tawm los thiab nws thiaj li tawg.Lub zog-rau-tus nqi piv ntawm cov hlau nplaum yog qhov zoo tshaj plaws ntawm cov hlau cam khwb cia.Lub zog ntawm ductile hlau yog piv rau cov cam khwb cia hlau.
2) Piv nrog cov cam khwb cia hlau, Cov cam khwb cia hlau muaj lub zog ntau dua, dua li cov hlau cam khwb cia.Tus nqi qis ntawm spherical graphite cam khwb cia hlau ua rau cov khoom siv no nrov dua, kev ua haujlwm zoo dua qub, thiab cov nqi ua haujlwm ntawm kheej kheej graphite cam khwb cia hlau raug txo.
3) Yog li ntawd, tom qab lub siab-loading qhov chaw ntawm ductile cam khwb cia hlau tau ua tiav los ntawm fertilizing annealing voj voog, cov qauv kheej kheej hauv cov ductile cam khwb cia hlau kuj tuaj yeem tshem tawm qhov tshwm sim tawg uas cov flake graphite hauv cov cam khwb cia hlau yog yooj yim los tsim.Hauv microphotograph ntawm cov khoom siv hlau, cov kab nrib pleb tuaj yeem pom tau txiav tawm tom qab ncav cuag lub pob graphite.Hauv kev lag luam hlau ductile, cov pob graphite no hu ua "crack stoppers" vim tias lawv muaj peev xwm tiv thaiv kev puas tsuaj.
