Cov kev cai yooj yim rau refractory bricks rau kilns
Lub hom phiaj tseem ceeb ntawm refractory bricks li kiln hauv ob sab phlu yog los txhim kho kev ua hauj lwm ntau lawm yam tsis ncua sij hawm ntau lawm vim kev puas tsuaj ntawm refractory bricks thaum lub sij hawm ntau lawm txheej txheem. Yog li ntawd, tsim nyog refractory bricks yuav tsum tau xaiv raws li cov yam ntxwv ntawm lub hnub nyoog ntawm lub cub tawg ntev thiab high efficiency. Lub refractory cib tsim los ntawm Henan refractory cib chaw tsim tshuaj paus yog ib qho inorganic non-metallic khoom uas muaj hluav taws kub tsis tsawg tshaj li 1580 ℃. Lub stability ntawm refractory bricks tiv thaiv kub nyob rau hauv tsis muaj load yog hu ua refractoriness, uas qhia txog lub hauv paus zog ntawm refractory bricks. Vim tias cov cib refractory feem ntau yog siv los ua cov khoom siv rau cov kub kub thiab lwm yam khoom siv thermal, nrog rau cov thawv kub kub thiab cov khoom siv hauv kev lag luam, nws tuaj yeem tiv taus ntau yam kev hloov pauv ntawm lub cev thiab cov khoom siv. Yog li ntawd, cov cai hauv qab no yuav tsum tau ua raws li:
(1) Txhawm rau kom ua tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm kub, nws yuav tsum muaj qhov kub txaus txaus uas tsis soften thiab yaj.
(2) Nws tuaj yeem tiv taus lub tshuab hluav taws xob thiab kev ntxhov siab thaum lub sijhawm ua haujlwm, tsis tas yuav poob lub zog ntawm cov qauv, softening deformation thiab vau ntawm qhov kub thiab txias, feem ntau yog qhia los ntawm qhov kub thiab txias.
(3) Thaum qhov kub thiab txias, qhov ntim tau ruaj khov, thiab lub qhov cub masonry los yog lub cev nchuav yuav tsis tawg vim kev nthuav dav ntawm cov khoom, thiab nws yuav tsis tawg vim lub shrinkage ntau dhau, yog li txo cov kev pab cuam lub neej. Nws yog feem ntau ntsuas los ntawm linear expansion coefficient thiab reheat shrinkage (los yog expansion).
(4) Refractory bricks yog heev cuam tshuam los ntawm cua sov tej yam kev mob. Lub tshuab hluav taws xob lub cev tau yooj yim puas vim qhov zoo ntawm qhov kub thiab txias tsis sib xws. Yog li ntawd, yuav tsum muaj qee qhov kev tiv thaiv thermal shock
(5) Thaum lub sij hawm siv, refractory bricks feem ntau raug rau cov tshuaj lom neeg ua kua, gases los yog cov khoom, ua rau cov khoom yuav corroded thiab puas. Yog li ntawd, cov khoom yuav tsum tau muaj ib tug tej degree ntawm corrosion kuj.
(6) Thaum lub sij hawm siv, refractory bricks feem ntau corroded los ntawm high-ceev nplaim taws thiab pa taws, ntxuav los ntawm cov kua hlau thiab slag, thiab cuam tshuam los ntawm hlau thiab lwm yam ntaub ntawv. Yog li ntawd, yuav tsum muaj lub zog txaus thiab hnav tsis kam.
Qhov zoo ntawm refractory bricks nyob ntawm nws cov kev ua tau zoo, uas yog tus qauv rau kev ntsuas cov khoom zoo. Qhov raug thiab tsim nyog xaiv ntawm refractory bricks kuj nyob ntawm cov khoom ntawm refractory bricks.
