Lub chute hauv ob sab phlu yuav raug hnav tiag tiag hauv daim ntawv thov txhua hnub. Tom qab ntawd, peb txheeb xyuas thiab sib piv plaub cov ntaub ntawv hauv ob sab phlu: hlau cam khwb cia hlau, stainless hlau, polyethylene molecule thiab hnav-resistant ceramics, thiab sib tham txog qhov tsim nyog ntawm kev nyiam hnav-resistant ceramic hauv ob sab phlu hauv hlau thiab hlau lag luam hauv ntau yam xws li hnav. tsis kam, cuam tshuam tsis kam thiab nyiaj txiag txiaj ntsig.
Sintering cog thiab coking cog coj hlau ore, coking thee thiab coke ua cov khoom siv raw thiab thauj cov khoom siv rau cov txheej txheem tom ntej; Lub voj voog 24-teev tau txais yuav, nrog cov dej ntws loj ntawm cov hlau ore, coking thee thiab coke thiab lub sijhawm pub mis ntev, uas yog ib qho yooj yim ua rau hnyav hnyav ntawm cov khoom siv tawm, tshwj xeeb tshaj yog chute; Nws feem ntau raug yuam kom nres rau kev kho thaum muaj xwm txheej ceev thaum tsim khoom, thiab qee qhov chutes tau nruab rau saum huab cua ntau tshaj kaum metres thiab kaum metres siab, yog li nws muaj teeb meem rau kev rhuav tshem thiab hloov lawv; Yog li ntawd, nws yog ib qho tseem ceeb tshwj xeeb los txhim kho qhov hnav tsis kam thiab cuam tshuam lub zog ntawm chute hauv ob sab phlu khoom.
Kev sib piv ntawm cov khoom ntawm cov khoom siv chute hauv ob sab phlu
1. Cam khwb cia hlau liner
Cam khwb cia hlau yog cov khoom siv hnav-resistant feem ntau siv hauv engineering. Raws li cov ntsiab lus carbon, cam khwb cia hlau muab faib ua peb hom: grey cam khwb cia hlau, dawb cam khwb cia hlau thiab hemp cam khwb cia hlau. Thaum nws yog siv los ua ib lub phaj hauv ob sab phlu, nws qhov hardness ntawm hb100 thiab 300. Nws yog ib qho nyuaj, tab sis nws tsis tuaj yeem txiav. Lub hauv paus phaj nrog cam khwb cia hlau raws li raw khoom yog nkig heev thiab tsis tuaj yeem ua rau hnyav hnyav.
2. Stainless hlau hauv ob sab phlu
Cov khoom siv ntawm cov hlau hauv ob sab phlu no yog ua los ntawm molybdenum chromium alloy. Nws hardness yog 2 los yog 3 npaug ntawm cov cam khwb cia hlau phaj, thiab nws cov kev pab cuam lub neej yog 12 npaug ntawm cov cam khwb cia hlau phaj. Nws tau ua tiav cov txiaj ntsig pom tseeb hauv kev txo cov plua plav thiab rov ua dua tus nqi thiab txo qhov poob ntawm daim ntawv sib txuas, tab sis nws cov kev hnav zoo yog tau los ntawm kev ua kom tawv tawv tsis tu ncua ntawm nws qhov chaw nyob rau hauv kev cuam tshuam muaj zog, Yog tias nws tsis muaj kev cuam tshuam txaus thiab kev ua haujlwm yog qhov tseem ceeb. Kev sib txhuam zoo li qub, nws cov yam ntxwv tsis tuaj yeem ua kom pom tseeb, thiab nws cov hnav tsis kam yog yuav luag zoo ib yam li cov pa roj carbon monoxide dav dav. Ntxiv mus, tus nqi ntawm stainless hlau hauv ob sab phlu phaj yog siab, nquag hloov yog ib qho yooj yim los ua cov khoom pov tseg zoo, thiab cov khoom sib txawv ntawm lub hauv paus hlau ntawm chute, uas yog teeb meem hauv vuam.
3. Polyethylene molecular liner
Polyethylene molecular khoom muaj cov yam ntxwv ntawm kev hnav tsis kam, tsis tshua muaj kev sib txhuam coefficient, kev ua haujlwm zoo zawv zawg, corrosion tsis kam, zoo rwb thaiv tsev kev ua tau zoo, lub teeb kev ntxhib los mos, ua haujlwm yooj yim, zoo poob siab thiab ntsiag to. Hauv kev lag luam hlau thiab hlau, nws tsuas yog siv rau hauv ob sab phlu ntawm cov khoom siv rau kev xa cov hlau nplaum hmoov thiab thee. Nws tseem tuaj yeem tiv thaiv suab nrov thiab ua lub luag haujlwm tiv thaiv ib puag ncig. Qhov dav dav thickness yog 10 ~ 30mm.
4. Ceramic hauv ob sab phlu
Qhov tseeb, cov ntaub ntawv hnav-resistant ceramic tau siv dav hauv cov phaj hauv cov teb chaws Europe thiab Asmeskas txij thaum xyoo 1990s. Lawv tsuas yog siv rau hauv cov khoom siv kho tshuab yooj yim xws li cov khoom siv thauj khoom, kev tshem tawm plua plav thiab cov hmoov tshauv tawm hauv thermal zog, steel, smelting, machinery, thee, mining, cement thiab chemical industries. Lawv tsuas yog siv hom alumina ua cov khoom siv tseem ceeb thiab ntxiv nrog rau lwm cov khoom xyaw, Nws yog sintered ntawm qhov kub siab txog 1700 ℃. Cov feem ntau siv hnav-resistant ceramic hauv ob sab phlu feem ntau suav nrog planar ceramic thaj, spherical ceramic thaj, tsho welded ceramic thaj, welded ceramic cib thiab anisotropic ceramic hauv ob sab phlu. Nws cov khoom xa mus rau: alumina cov ntsiab lus 92%, ntom 3.6g / cm3, Rockwell hardness 85hra, compressive zog 850mpa, tawg toughness kic4 · 8Mpa · ML2, flexural zog 290mpa, thermal conductivity 20W / m · K thiab thermal expansion coefficient 7. -6m / m · Ko yog tus cwj pwm los ntawm kev hnav tsis zoo, muaj kev cuam tshuam rau kev ua haujlwm siab, kev kub siab ua haujlwm (nws tuaj yeem ua haujlwm ntawm 0 ℃ thiab 250 ℃ rau lub sijhawm ntev), zoo ua haujlwm tsis muaj zog alkali thiab tsis muaj zog acid, zoo tiv thaiv kev poob. , yooj yim installation thiab hloov, ultra-siab hnav tsis kam thiab txo txij nkawm lub sij hawm.
