Alumina hnav-resistant hauv ob sab phlu, tseem hu ua ceramic hauv ob sab phlu los yog txhuas oxide hnav liners, yog ib yam tshiab ntawm high-efficiency hnav-resistant khoom. Nws muaj cov khoom zoo heev xws li siab hardness, siab ceev, hnav tsis kam, corrosion kuj, thiab kub tsis kam. Alumina hnav-resistant hauv ob sab phlu daim hlau yog dav siv nyob rau hauv lub zog tsim, metallurgy, cement, tshuaj lom neeg kev lag luam, mining thiab lwm yam lag luam.
Yog li, leej twg yuav peb cov alumina hnav liner? Qhov tseeb, ntau lub tuam txhab hauv ntau qhov kev lag luam tau lees paub qhov kev ua tau zoo ntawm alumina hnav-tiv taus hauv ob sab phlu thiab xaiv los siv lawv ua cov ntaub ntawv hauv ob sab phlu los daws cov teeb meem hnav-tiv taus ntawm lawv tus kheej cov khoom. Piv txwv li, peb nyuam qhuav xa ib lub thawv ntawm hnav-resistant alumina ceramic phaj rau peb cov neeg muas zaub Nyab Laj.
Qhov zoo ntawm aluminium oxide hnav liners yog raws li nram no:
1. High hardness thiab zoo heev hnav tsis kam
Lub hardness ntawm alumina hnav-resistant hauv ob sab phlu yog HRA80-90, thib ob tsuas yog pob zeb diamond, thiab nws hnav tsis kam yog 266 npaug ntawm manganese hlau thiab 171.5 npaug ntawm cov chromium cam khwb cia hlau.
2. Kub kub tsis kam
Alumina hnav-tiv taus hauv ob sab phlu tuaj yeem tiv taus qhov kub siab txog li 1700 degree thiab tsim nyog rau cov ntawv siv kub-resistant.
3. Corrosion kuj
Alumina hnav-resistant hauv ob sab phlu muaj zoo heev corrosion kuj thiab muaj peev xwm tiv taus corrosion ntawm acid thiab alkali daws, nrog rau kev yaig ntawm molten iav thiab molten hlau.
4. Yooj yim rau nruab thiab tswj
Alumina hnav-resistant hauv ob sab phlu tuaj yeem ntsia tau rau saum npoo ntawm cov cuab yeej siv ntau txoj hauv kev xws li vuam, kev sib txuas, thiab kho tshuab, thiab yooj yim los hloov thiab tswj.
Cov ntawv thov tseem ceeb ntawm aluminium oxide hnav liners yog:
1. Coal-fired fais fab kev lag luam
Alumina hnav-tiv taus hauv ob sab phlu tuaj yeem siv los ua cov hlua khi rau cov thee mills thiab thee hoppers, uas tuaj yeem daws cov teeb meem hnav los ntawm kev kub ceev thiab kub pulverized thee.
2. Kev lag luam metallurgical
Alumina hnav-resistant hauv ob sab phlu daim hlau yuav siv tau raws li hauv ob sab phlu ntawm ntau yam furnaces thiab yog resistant rau kub kub, hnav thiab corrosion.
3. Kev lag luam cement
Alumina hnav-resistant hauv ob sab phlu tuaj yeem siv los ua cov ntaub ntawv sib tsoo, cov khoom siv thauj khoom thiab lwm yam khoom siv hauv cov nroj tsuag cement.
4. Kev lag luam tshuaj
Alumina hnav-resistant hauv ob sab phlu tuaj yeem siv los ua cov ntaub qhwv rau cov reactors, cia tso tsheb hlau luam, thiab cov kav dej, thiab tuaj yeem tiv thaiv corrosion los ntawm cov kua qaub thiab alkali.
Hauv cov ntsiab lus, alumina hnav-resistant liners muaj kev ua tau zoo zoo thiab kev siv dav, ua rau lawv muaj kev xaiv nrov thiab txhim khu kev qha rau kev daws teeb meem hnav-tiv taus hauv cov khoom siv.
