DUTTILE IRON cov kab ntau lawm tau qhia thiab ua haujlwm txij li xyoo 2021

Zas Hlau Hoobkas tau tsim txij li xyoo 2021

1. Qhia Taw Qhia:
Cam khwb cia hlau zas yog cov khoom siv dag zog zoo uas tau tsim hauv xyoo 1950. Nws qhov kev ua tau zoo nyob ze rau ntawm cov hlau. Raws li nws qhov kev ua tau zoo tshaj plaws, nws tau ua tiav siv los pov tseg qee lub zog nyuaj thiab nrog qhov xav tau ntau ntawm lub zog, tawv, thiab hnav tsis kam. Cov hlau cam khwb cia tau tsim sai sai rau hauv cov khoom siv hlau nrum thib ob tsuas yog rau cov hlau cam hlau thiab siv dav. Qhov hu ua "hloov hlau rau hlau" feem ntau yog hais txog hlau zas. Cam khwb cia hlau tau txais cov zas graphite los ntawm spheroidization thiab inoculation kev kho mob uas ua tau zoo txhim kho cov yam ntxwv ntawm cov hlau cam khwb cia, tshwj xeeb tshaj yog cov yas thiab tawv, yog li tau txais lub zog siab dua li cov hlau.

2. Kev Ua Tau Zoo:
Cov hlau cam khwb cia hlau tau yuav luag tau siv hauv txhua qhov kev lag luam loj, uas xav tau lub zog siab, yas, tawv, hnav tsis kam, hnyav cua sov thiab tshuab ua haujlwm poob siab, siab lossis tiv taus kub, tiv taus xeb, thiab qhov ruaj khov. Txhawm rau ua kom tau raws li cov kev hloov pauv no hauv kev siv, cov hlau zas hlau muaj ntau qib, muab ntau yam khoom siv thiab lub cev.

3.Material: QT450-10

4.Application:
Cov khoom siv hlau cam khwb cia hlau seem rau cov khoom seem hauv qab, zoo li lub npog kawg rau cov menyuam nqa khoom, lub dab tshos rau cov menyuam taug qab, tus ncej rau tus tsis siv neeg

5. Muaj peev xwm ntau lawm: 500-550T/Hli, Cov kab ntau lawm.

6. Kev xav:
1) Sib piv nrog cov hlau cam khwb cia, cov zas cam khwb cia hlau muaj qhov zoo tshaj plaws hauv lub zog. Lub zog tensile ntawm cov hlau cam khwb cia hlau yog 60k, thaum lub zog tensile ntawm cam khwb cia hlau tsuas yog 31k. Lub zog tawm los ntawm cov hlau cam khwb cia hlau yog 40k, thaum cov hlau cam khwb cia tsis qhia pom lub zog tawm los thiab thaum kawg tawg. Lub zog-rau-tus nqi piv ntawm cov hlau zas yog zoo dua li cov hlau cam khwb cia. Lub zog ntawm cov hlau zas yog piv rau cov hlau cam khwb cia.

2) Sib piv nrog cov hlau cam khwb cia, Cov zas cam khwb cia hlau muaj lub zog tawm los ntau dua, dua li cov hlau cam khwb cia. Tus nqi qis ntawm kheej kheej graphite cam khwb cia hlau ua rau cov khoom siv no nrov dua, kev ua haujlwm tau zoo dua yog siab dua, thiab kev ua haujlwm ntawm cov duab kheej kheej graphite cam khwb cia hlau raug txo.

3) Yog li ntawd, tom qab qhov chaw thau khoom nrawm ntawm cov hlau cam khwb cia tau ua tiav los ntawm kev siv lub tshuab ua kom sov, cov qauv kheej kheej hauv cov zas zas hlau kuj tseem tuaj yeem tshem tawm qhov tshwm sim tawg uas flake graphite hauv cov hlau nrum tau yooj yim los tsim. Hauv microphotograph ntawm cov hlau zas, cov kab nrib pleb tuaj yeem pom los txiav tom qab mus txog pob graphite. Hauv kev lag luam hlau zas, cov khoom siv graphite no hu ua "cov nres tawg" vim tias lawv muaj peev xwm tiv thaiv kev tawg.
