Welded ceramic hnav-resistant hauv ob sab phlu.
Cov ntaub ntawv no tej zaum yuav tsis paub zoo rau qee cov neeg nyeem, tab sis nws ua lub luag haujlwm tseem ceeb hauv kev tu cov cuab yeej hauv kev lag luam xws li mining, fais fab, thiab cement.
1. Cov ntsiab lus tseem ceeb ntawm welded ceramic hnav-cov ntaub ntawv tiv taus.
Welded ceramic hnav-cov ntaub ntawv tiv taus feem ntau muaj ob ntu: cov ceramic thaiv thiab cov hlau puag phaj. Ceramic block yog lub hauv paus tseem ceeb, feem ntau yog ua los ntawm alumina ceramics, uas paub txog nws qhov siab hardness thiab zoo hnav tsis kam. Lub hauv paus hlau phaj feem ntau yog ua los ntawm qis- carbon steel thiab ua haujlwm pabcuam thiab kev sib txuas. Thaum lub sij hawm tsim cov txheej txheem, cov ceramic thaiv yog tsau rau ntawm lub hauv paus hlau phaj los ntawm cov txheej txheem vuam tshwj xeeb, tsim ib chav ua tiav liner. Qhov kev tsim no sib txuas cov hnav tsis kam ntawm ceramics nrog lub toughness ntawm hlau, ua rau lub liner ob leeg khov kho thiab yooj yim rau nruab.
2. Cov yam ntxwv tseem ceeb thiab qhov zoo
Cov yam ntxwv tseem ceeb ntawm cov welded ceramic hnav- cov kab resistant yog raws li hauv qab no. Ua ntej, nws muaj kev hnav zoo heev. Lub siab tawv ntawm cov khoom siv ceramic tuaj yeem tiv taus kev sib txhuam thiab kev cuam tshuam ntawm cov ntaub ntawv, txo cov khoom hnav. Qhov thib ob, nws yooj yim rau nruab. Los ntawm txoj kev vuam, lub liner tuaj yeem txuas nrog rau saum npoo ntawm cov khoom siv, hloov mus rau ntau yam duab. Cov liner no kuj muaj kev tiv thaiv corrosion zoo thiab tuaj yeem nyob ruaj khov nyob rau hauv acidic thiab alkaline ib puag ncig. Nws yog qhov hnyav heev thiab tsis ua rau lub nra hnyav ntawm cov khoom siv. Nws cov nqi txij nkawm yog tsawg, thiab ib zaug ntsia, nws tuaj yeem siv tau ntev, txo qis sijhawm.
3. Piv txwv ntawm Daim Ntawv Thov Scenarios
Hom phaj phaj no yog siv dav hauv ntau qhov chaw lag luam. Piv txwv li, nyob rau hauv kev lag luam mining, nws yog feem ntau siv nyob rau hauv conveying pipelines, chutes thiab nyob rau hauv lub crushers los tiv thaiv hnav ntawm ores thiab slag. Hauv kev lag luam hluav taws xob, nws kuj tseem siv rau hauv cov thee hmoov conveying tshuab thiab cov cuab yeej tshem tawm plua plav los tiv thaiv qhov kub ntawm - kub thiab siab - hnav ib puag ncig. Cov khoom siv raw khoom sib tsoo thiab clinker txias cov cuab yeej hauv cov nroj tsuag cement kuj xav tau cov phaj hauv ob sab no los tiv thaiv cov khoom siv. Nws kuj tau pom ntau zaus hauv kev lag luam xws li metallurgy thiab chemical engineering, pab cov cuab yeej ua haujlwm ruaj khov hauv cov xwm txheej hnyav.
4. Kev teeb tsa thiab kev saib xyuas cov ntsiab lus tseem ceeb
Thaum txhim kho cov welded ceramic hnav-cov ntaub ntawv tiv thaiv, ob peb kauj ruam tseem ceeb yuav tsum tau them sai sai rau. Xyuas kom meej tias cov cuab yeej nto yog huv si, tiaj tus, tsis muaj roj stains thiab xeb, kom lav qhov vuam zoo. Raws li cov duab ntawm cov khoom siv thiab qhov chaw hnav, txiav thiab npaj cov txheej txheem hauv ob sab phlu kom tsis txhob muaj qhov khoob. Thaum lub sij hawm vuam txheej txheem, siv tshwj xeeb vuam rods thiab tswj cov vuam kub kom zoo los tiv thaiv cov ceramics los ntawm cracking. Tom qab kev teeb tsa, xyuas seb lub vuam seam puas ruaj. Yog tias tsim nyog, ua cov vuam txuas ntxiv. Kev saib xyuas txhua hnub feem ntau suav nrog kev tshuaj xyuas tsis tu ncua kom pom tias cov kab hlau hauv ob sab yog xoob lossis puas, thiab tam sim ntawd daws cov teeb meem me me kom tsis txhob nthuav dav ntawm qhov cuam tshuam.
5. Sib piv nrog Lwm Cov Hnav-cov ntaub ntawv tiv taus
Piv nrog cov hlau zoo tib yam lossis cov roj hmab liner, welded ceramic hnav- cov ntaub ntawv tiv taus muaj txiaj ntsig zoo dua ntawm kev hnav tsis kam. Txawm hais tias cov ntaub ntawv hlau muaj lub zog siab, lawv muaj qhov tsis tshua muaj zog thiab yooj yim hnav; roj hmab liners muaj elasticity zoo, tab sis tsis resistant rau high kub thiab ntse ntaub ntawv. Ceramic liners, ntawm qhov tod tes, muab cov hardness siab thiab qee qhov toughness, ua rau lawv muaj ntau yam. Txawm li cas los xij, lawv cov nqi kuj tseem siab dua, thiab kev nqis peev thawj zaug tuaj yeem siab dua me ntsis ntawm cov khoom siv hlau. Tab sis nyob rau hauv lub sij hawm ntev, vim lawv lub neej kev pab cuam ntev dua, tag nrho cov nqi yuav raug nqi ntau dua.
6. Cov lus qhia xaiv thiab siv
Thaum xaiv cov welded ceramic hnav-cov ntaub uas tiv taus, nws yog qhov yuav tsum tau txiav txim siab raws li cov kev ua haujlwm tshwj xeeb. Piv txwv li, nyob rau hauv siab - cuam tshuam ib puag ncig, thicker ceramic blocks yuav tsum raug xaiv; rau corrosive ib puag ncig, corrosion kuj ntawm ceramic thiab hlau substrate yuav tsum tau ua kom ntseeg tau. Nws raug nquahu kom cov neeg siv yuav los ntawm cov tuam txhab muaj npe nrov thiab ua tib zoo saib xyuas cov khoom pov thawj zoo kom tsis txhob muaj cov khoom siv tsis zoo los ntawm cov khoom tsis zoo. Thaum siv, ua raws li cov kev qhia tshwj xeeb ntawm kev teeb tsa thiab ua cov kev tshuaj xyuas tsis tu ncua kom ua haujlwm zoo rau nws txoj haujlwm tiv thaiv.
