Sib txawv Wear-Resistant Luj Tshib los ntawm Traditional Luj Tshib
Hnav-tiv taus lub luj tshib tau txais kev lees paub hauv kev ua lag luam thiab tau hloov pauv qee cov ntaub ntawv hnav-tiv taus xws li cam khwb cia hlau, cam khwb cia hlau, thiab cov khoom siv centrifugal-cam khwb cia. Qhov laj thawj tseem ceeb tom qab qhov no yog lawv cov khoom zoo tshaj plaws hauv kev sib piv rau cov khoom siv niaj hnub. Hauv kev sib tham no, peb yuav sib txawv lub luj tshib hnav-tiv taus los ntawm lub luj tshib tsoos raws li ob yam hauv qab no.
(1) Kev sib piv kev ua haujlwm
1. Cam khwb cia hlau:
Yav dhau los, ntau lub Hoobkas feem ntau siv cam khwb cia hlau rau lub luj tshib. Cam khwb cia hlau luj tshib yog yus muaj los ntawm lawv brittleness, susceptibility rau tawg, nto hnav, thiab phab ntsa thicknesses ntawm kwv yees li 25mm thiab 35mm. Tom qab lub sijhawm luv luv ntawm kev hnav thiab tawg, thee plua plav hnav tshwm sim vim qhov khoob, ua rau muaj kev hloov kho loj dua li lawv lub neej. Cov luj tshib no feem ntau muaj cov pores sab hauv, tsim kom muaj kev phom sij. Thaum cov pores nkag mus, lawv ua irreparable.
2. Hlau Casting:
Cam khwb cia hlau, nrog rau cov hlau alloy, yog siv dav hauv kev hnav-tiv taus daim ntaub ntawv vim yog cov txheej txheem tsim khoom ncaj qha. Txawm li cas los xij, qhov nyuaj ntawm cov hlau cam khwb cia (ib puag ncig 60) yog qhov qis dua li ntawm ceramics (80 thiab siab dua). Yog li ntawd, qhov hnav tsis kam yog tsuas yog ib feem kaum ntawm ceramics. Lub luj tshib tsim nrog cam khwb cia hlau tau hnav tawm hauv me ntsis dhau ib xyoos. Tsis tas li ntawd, cam khwb cia steel kav muaj siab tuab, loj ntim, siab carbon cov ntsiab lus, thiab weldability tsis zoo, yuav tsum tau nyob rau hauv lub tshav kub kev kho mob ntawm welds, uas ua rau muaj teeb meem loj rau installation thiab txij nkawm.
3. Centrifugally Cast Composite Ceramic Yeeb Nkab:
Cov txheej txheem no suav nrog tus kheej-propagating centrifugal casting thiab siv tshuaj lom neeg cov tshuaj tiv thaiv, exothermic combustion, thiab synthesis ntawm cov khoom tshiab thaum lub sij hawm combustion yoj propagation. Ceramic composite kav tsim los ntawm txoj kev no qhia txog kev hnav tsis kam piv rau carbon steel thiab manganese steel kav. Txawm li cas los xij, vim qhov ntsuas kub tsis tshua muaj siab (qhov nruab nrab qhov kub tsis tshaj 1200 degree), alumina tsim yog theem qis-kub, uas txawv ntawm qhov kub-kub theem ntawm lub zog, hardness, thiab ntom. Tsis tas li ntawd, lub sij hawm luv luv ua rau kev sib cais tsis tiav ntawm alumina thiab molten hlau ntawm qhov kub thiab txias, ua rau cov porous, low-density ceramics nrog tsawg hardness.
4. Hnav-Resistant Luj Tshib (95 Ceramic):
Cov luj tshib no yog tsim los nrog cov ntsiab lus alumina tsis pub tsawg dua 95% thiab muaj tag nrho ntawm qhov kub thiab txias theem -Al2O3, nrog sintering kub mus txog 1670 degree. Qhov no ua kom cov khoom zoo tshwj xeeb. Nyob rau hauv cov nqe lus ntawm kev hnav tsis kam, lub neej kev pab cuam ntawm hnav-resistant luj tshib yog tshaj tsib npaug ntawm centrifugal-cam khwb cia composite ceramic luj tshib.
Ntxiv mus, cov txheej txheem centrifugal casting txwv qhov kev siv ntawm cov kav dej ceramics mus rau cov ntu ncaj. Feem ntau, lawv tsis tuaj yeem ua rau khoov lossis me me nkhaus. Txhawm rau tsim lub luj tshib lossis cov kav dej me me, cov yeeb nkab ncaj yuav tsum tau muab faib ua ob peb ntu welded. Tsim lub luj tshib thiab khoov me me muaj cov phab ntsa uas tsis muaj kev cuam tshuam, cuam tshuam cov khoom thauj thiab txo cov khoom tso tawm.
Tsis tas li ntawd, cov ceramics feem ntau muaj ntau cov microcracks, ua rau lawv nkig thiab tawg. Lawv yooj yim rau chipping, tawg, thiab tsis kho. Thaum xav txog tag nrho cov boiler ncua kev kawm ntawv muaj peev xwm, qhov hnyav thiab thickness ntawm cam khwb cia hlau luj tshib, thiab cam khwb cia hlau luj tshib 'abrasion nto phab ntsa thickness, nws yuav pom tseeb hais tias lub luj tshib nrog abrasion nto tshaj 40 hli yuav undoubtedly nce lub luj ntawm lub ncua kev kawm ntawv thiab txo nws cov lifespan. .
Hauv cov ntsiab lus, lub luj tshib hnav-tiv taus muaj txiaj ntsig zoo, txawm tias xav txog cov nqi pib nqis peev lossis cov nuj nqis ua haujlwm. Tus nqi-rau-lub neej piv ntawm hnav-tiv taus luj tshib ho outperforms ib txwm luj tshib. Nrog cov nyiaj siv los yuav ib lub luj tshib, koj tuaj yeem tau txais ob lub luj tshib-resistant ceramic. Kev pab lub neej ntawm hnav-resistant ceramic luj tshib yog ob zaug ntawm lub luj tshib alloy.
