Product Overview
RQTSi5 yog Suav -tus qauv siab- silicon tshav kub- cov hlau tsis muaj zog (tseem hu ua QTRSi5 nyob rau hauv GB / T 9437-2009) tsim tshwj xeeb rau cov khoom siv uas ua haujlwm nyob rau hauv qhov siab siab -kub, oxidizing rauv {{1}. Nrog cov ntsiab lus ntawm silicon ntawm 4.5-5.5%, RQTSi5 tsim cov ntom ntom, kho nws tus kheej SiO₂ oxide nplai ntawm qhov chaw casting, uas ua raws li kev tiv thaiv ntxiv hauv oxidation thiab muab cov khoom nws tus yam ntxwv tsis kam mus rau scaling, thermal qaug zog, thiab kev loj hlob ntawm qhov kub thiab txias.
Ntawm Juhe Yulong Special Steel Co., Ltd., peb tsim RQTSi5 boiler fittings thiab cua sov- resistant castings rau cov neeg siv khoom kos duab thiab specifications, pab cov boiler muaj OEMs, fais fab nroj tsuag tu pab pawg, pov tseg- rau- cov tswv fais fab, thiab metallurgical khoom neeg muag khoom thoob ntiaj teb. Nrog rau ntau tshaj kaum xyoo ntawm kev paub txog kev tsim, peb xa tsis tau tsuas yog RQTSi5 qhov chaw xwb tab sis kuj muaj tag nrho cov spectrum ntawm tshav kub-tiv taus thiab hnav- cov ntaub ntawv pov thawj resistant - yog li koj tuaj yeem tau txais txhua qhov siab - kub haum los ntawm ib tus neeg muag khoom.
Chemical Composition & Mechanical Properties
Tag nrho RQTSi5 castings peb tsim ua raws li GB/T 9437-2009 (Heat-Resistant Cast Iron Parts). Kev txheeb xyuas qhov muaj pes tsawg leeg thiab cov khoom muaj raws li hauv qab no:
Khoom Description
| Element | C | Si | Mn | P | S |
| Ntau yam | 2.4 – 3.2 | 4.5 – 5.5 | Tsawg dua los yog sib npaug li 0.7 | Tsawg dua lossis sib npaug li 0.10 | Tsawg dua lossis sib npaug li 0.03 |
Qhov 4.5-5.5% silicon ntau yog cov ntsiab lus ntawm RQTSi5. Kev tshawb nrhiav thiab kev xyaum ua ob qho tib si paub meej tias cov ntsiab lus silicon yuav tsum ncav cuag li 4% lossis siab dua ua ntej SiO₂ nto zaj duab xis ua kom txaus los ua kom muaj txiaj ntsig oxidation tsis kam thiab thermal- qaug zog txhim kho. RQTSi5 zaum zoo tshaj qhov pib.

Thaum tshav kub kub -Resistance Rating
- Kev pabcuam txuas ntxiv hauv huab cua / cua sov: mus txog 800 degree
- Nyob rau sab sauv txwv silicon (≈5.5% Si): mus txog 900 degree
- Nyob rau hauv qhov chaw siv boiler combustion zones, RQTSi5 grate bars thiab lub cub tawg fittings niaj hnub tswj cov nplaim taws kub ntawm 900-950℃nrog rau lub cub tawg chamber kub nyob ib ncig ntawm 1,000 degree, nrog rau cov pov tseg -incineration grate systems.
Vim li cas RQTSi5 rau Boiler Fittings
Silicon-Based Oxidation Resistance - Tsis yog "Tsuas Kub-Tlerant"
Tsis zoo li cov hlau grey zoo tib yam (HT150/HT200) lossis cov qauv hlau (QT450-10), RQTSi5 tso siab rau cov hlau alloy- qib silicon es tsis yog chromium lossis npib tsib xee rau nws qhov siab -kub kev ua haujlwm. Thaum pib cua sov, silicon xaiv oxidizes ntawm qhov chaw los tsim ib txheej nyias, iav SiO₂ txheej. Cov txheej no yog nruj me ntsis adherent, muaj cov pa oxygen diffusivity tsawg, thiab ib nrab ntawm tus kheej- kho yog khawb thaum caij tsheb kauj vab. Qhov tshwm sim yog txo qis "kev loj hlob" (qhov kev nthuav dav mus tas li) thiab kev ntsuas - ob hom tsis ua haujlwm tseem ceeb rau boiler grate tuav thiab lub cub tawg sab hauv.
Ductile Iron Matrix rau Load-Bearing Capacity
RQTSi5 yog ductile (spheroidal graphite) hlau, tsis yog grey hlau. Lub spheroidal graphite morphology muab nws chav siab dua -kub tensile zog (Ntau dua los yog sib npaug rau 370 MPa) thiab zoo cuam tshuam tsis zoo dua flake-graphite tshav kub-resistant grey irons xws li RTSi5. Qhov no yog qhov tseem ceeb rau grate tuav uas yuav tsum txhawb nqa qhov hnyav ntawm lub txaj roj, rau lub qhov rooj ntawm lub qhov rooj uas muaj cov khoom siv thauj khoom, thiab cov yeeb nkab txhawb nqa nqa thermal - nthuav dav kev ntxhov siab.
Tus nqi -Txoj kev hloov pauv kom sov-Resistant Steel
Rau kev pabcuam kub txog 800-900 degree, RQTSi5 muab oxidation tsis kam ntawm cov khoom siv thiab cov nqi casting zoo hauv qab cua sov-cov hlau tsis muaj zog xws li ZG30Cr18Mn12Si2N, 1.4777 (GX40CrSi13), lossis 310 stainless hlau. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom loj, hnyav, lossis cov khoom siv boiler uas yuav tsum tau hloov ntau zaus - grate tuav, hnav daim hlau, baffles, thiab rauv hauv ob sab phlu.
