Featured Snippet
Nitrided steel yog suav tias yog tus qauv yam tsawg kawg nkaus rau extruder screws vim nws muab:
- High deg hardness (HV 900-1100) rau hnav tsis kam
- Cov tub ntxhais muaj zog toughness los tiv thaiv kev tawg
- Zoo heev corrosion kuj tiv thaiv ya raws thiab raw cov ntaub ntawv
- Lub neej ua haujlwm ntev dua piv rau cov tsis kho lossis qis- qib steel
- Kev ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias
Kev siv cov khoom qib qis dua - tuaj yeem ua rau hnav sai, tsis ruaj khov extrusion, thiab nce nqi kho.
Vim li cas Screw Material txiav txim siab Extruder Performance?
Nyob rau hauv ib lub ntsia hlau floating ntses pellet txiag tshuab, cov ntsia hlau tsis yog ib feem xwb. Nws yog lub plawv ntawm tag nrho cov kab ke, tsis tu ncua raug kub, siab, kev sib txhuam, thiab cov khoom corrosive. Yog tias cov ntsia hlau ua tsis tiav, tag nrho cov kab ntau lawm nres.
Xaiv cov khoom siv ntsia hlau zoo zoo li xaiv cov caj qaum ntawm koj lub peev xwm ntau lawm. Ntawm txhua qhov kev xaiv, nitrided steel tau dhau los ua kev lag luam hauv paus rau kev ua tau zoo.
Dab tsi yog Extruder Screw thiab Vim Li Cas Nws Tseem Ceeb?
Ib qho ntsia hlau ntses noj tshuab ua lub luag haujlwm rau:
- Kev xa khoom raw
- Compressing thiab cua sov cov khoom
- Tsim lub zog shear rau kev ua noj thiab nthuav dav
- Nws qhov kev ua tau zoo cuam tshuam ncaj qha rau:
- Khoom zoo
- Ntau lawm efficiency
- Cov khoom siv lifespan
Cov ntsia hlau ua tsis zoo tuaj yeem ua rau cov zis tsis sib xws thiab nquag poob qis.
Nitrided Steel yog dab tsi?
Nitrided steel yog ib hom hlau alloy uas dhau los ntawm kev kho cua sov nitriding.
Txheej txheem txheej txheem:
- Nitrogen atoms yog diffused rau hauv txheej txheej
- Ib qho nyuaj, hnav- txheej tiv taus yog tsim
Cov khoom tseem ceeb:
- Nto hardness: HV 900-1100
- Nitriding qhov tob: 0.3-0.6 hli
- Siab tiv taus hnav thiab corrosion
Qhov no tsim ib "lub plhaub tawv + tawv core" qauv zoo tagnrho rau qhov chaw extrusion.
Vim li cas Nitrided Steel Yog Tus Qauv Tsawg?
1. Superior Wear Resistance
- Thaum lub sij hawm extrusion, cov ntsia hlau tas li rubs tawm tsam cov ntaub ntawv raw thiab lub thoob.
- Nitrided txheej ho txo qhov hnav
- Khaws cov ntsia hlau geometry thaum lub sijhawm
- Tsis muaj nitriding, screws hnav sai sai, cuam tshuam cov khoom sib xws.
2. Kev kub siab thiab siab ruaj khov
Extrusion muaj cov xwm txheej hnyav:
- Kub mus txog 160℃lossis siab dua
- Kev kub siab tsis tu ncua
- Nitrided steel tuav cov txheej txheem kev ncaj ncees nyob rau hauv cov xwm txheej no, tiv thaiv deformation.
3. Corrosion Resistance
Cov khoom siv raw feem ntau muaj:
- Moisture
- Protein
- Cov tshuaj ntxiv
- Cov no tuaj yeem ua rau corrosion.
Nitrided steel muab cov txheej txheej tiv thaiv uas tiv thaiv cov tshuaj lom neeg puas tsuaj.
4. Lub neej ua haujlwm ntev dua
Piv rau cov pa roj carbon zoo tib yam:
- Kev pabcuam lub neej nce 2-3 zaug
- Txo qhov hloov zaus
- Tus nqi kho mob qis dua
Nws tsis yog ib qho kev xaiv khoom nkaus xwb, tab sis tus nqi -txuag lub tswv yim.
5. Cov khoom ruaj khov zoo
Ib tug ntswj ntsia hlau ua rau:
- Siab tsis sib haum
- Ua noj tsis sib xws
- Cov pellet tsis zoo
Nitrided screws tuav ruaj khov geometry, kom ntseeg tau tias cov zis zoo ib yam.
Kev sib piv: Nitrided Steel vs Lwm cov ntaub ntawv
