Thaum tshav kub kub Reverist steel Grate 1.4845
EU cov teb chaws feem ntau ua raws cov qauv kev nruj thiab kev tiv thaiv ib puag ncig hauv kev xaiv cov steel ua kom tus txheej txheem kub. Kev xaiv cov khoom tsis tau them rau kev ua haujlwm siab, tab sis kuj yuav siv mus rau hauv tus account corrosion tsis kam, kev lag luam thiab kev ua raws. Cov hauv qab no yog cov khoom EU ntau yam thiab lawv cov yam ntxwv thov:
1. Cov ntaub ntawv tseem ceeb thiab European cov qauv
(1) Austenicic Stainless Hlau (Austenitic Stainless Hlau)
Cov npav raug:
1.4845 (x [5Crnisi2521, sib raug rau peb 310s):
Lub antioxidant kub tuaj yeem ncav cuag 1100 degree, uas yog dav siv nyob rau hauv kev kub siab corrosion.
1.4833 (x12crni2313, sib raug rau peb 309s):
Lub antioxidant kub yog li 1000 degree, thiab tus nqi qis me ntsis, uas haum rau nruab nrab thiab kub kho cua sov thiab cua sov rhuab.
Cov yam ntxwv:
Cov ntsiab lus Chromium thiab Nickel Cov Lus (CR 2025%, NI 1220%) muab cov oxidosion zoo, yog kev xaiv vuam zoo, yog cov kev xaiv vuam hauv European Union.
(2) Ferric lub cev stainless hlau (ferritic stainless hlau)
Cov npav raug:
1.4762 (x10cralsi25, sib haum rau peb 446):
Nrog cov ntsiab lus chromium siab (25% cr) thiab antioxidant kub txog li 900 degree, nws yog qhov haum rau oxidation ib puag ncig xws li cov hluav taws kub tua hluav taws.
Cov yam ntxwv:
Tus nqi yog tsawg, tab sis lub zog kub thiab thermal kub ua tau tsis muaj zog dua li cov hlau tsis muaj zog tshaj li cov hlau tsis tshua muaj txiaj ntsig.
(3) nickel-raws li alloy (nickelbased alloys)
Cov npav raug:
Inconel 600 (2.4816):
Qhov kub kub tiv thaiv 1200 degree +, permoulce permburization thiab sulfide corrosion, siv hauv qhov kub thiab txias kub siab.
Inconel 625 (2.4856):
Ntxiv Molybdenum thiab niobium, tiv taus chloride ion corrosion, haum rau kev ua tubrog chaw lossis thaj chaw ntub dej ntawm cov khib nyiab pov tseg.
Cov yam ntxwv:
Kev ua tau zoo heev tab sis tus nqi siab, EU feem ntau siv rau cov tseem ceeb lossis kev tswj hwm siab yuav tsum tau ua siab corrosion.
(4) Thaum tshav kub kub-resistant cam khwb cia hlau (hetresistant cam khwb cia hlau)
Cov npav raug:
GX40CRSI28 (enjs1029):
Siab chromium cam khwb cia hlau (2530% CR), hnav zoo heev, siv rau cov hmoov tshauv ntawm cov grate hnav thaj chaw.
Cov yam ntxwv:
Tus nqi qis thiab hnav tsis kam, tab sis loj brittleness, yuav tsum zam kev cuam tshuam kev cuam tshuam, ntau yam hauv kev txhawb zog ntawm biomass boilers.
2. Qhov ntau yam cuam tshuam cov khoom xaiv
(1) Kev tiv thaiv ib puag ncig muaj kev tsav tsheb
Cov neeg European Union Khib Nyiab Cov lus qhia (dav 2000/76 / EC) yuav tsum tau tswj hwm cov roj chioxin thiab txhawb nqa cov roj ntsha cov khoom siv nyiaj npib siab (piv txwv li 1.4845 lossis inconel 625).
(2) Cov qauv zog zog
EU Erological Directive (ERP) Txhawb nqa cov txheej txheem cua tshuab, grate yuav tsum tau ua kom zoo cua tsim), thiab cov ntaub ntawv nrog ob lub zog kub thiab lub teeb yuag.
(3) cov tseev kom muaj rau kev lag luam ncig
The material should be recyclable (such as stainless steel recovery rate>90%), thiab cov feem ntawm Refractory cam khwb cia hlau yog maj mam txo qis vim qhov nyuaj ntawm kev rov qab zoo.
3. Raug ntawv thov cov xwm txheej nrog cov ntaub ntawv
Daim Ntawv Thov Kev Pab Cuam
Feem ntau siv nyob rau hauv European Union
Cim npe nrov: Thaum tshav kub kub Resistant steel grate 1.4845, Tuam Tshoj Kub Resistant Steel grate 1.4845 manufacturers, lwm tus neeg, Hoobkas
