Cov khoom siv twg yog qhov zoo rau cov khoom siv ntawm lub qhov cub hluav taws xob? Muaj ntau cov ntaub ntawv siv rau cov khoom siv pouring ntawm lub qhov cub npog, thiab nws tsis tuaj yeem txiav txim siab seb cov khoom twg zoo dua. Nws yog nyob ntawm qhov kev yaig ntawm qhov sib txawv ntawm qhov cub kub kom xaiv cov khoom tsim nyog.
Lub qhov cub hluav taws xob tuaj yeem siv cov txheej txheem cement uas tsis tshua muaj hluav taws xob npog castable, thaum lub qhov cub hluav taws xob npog yog tsim rau siv nrog cov hlau fiber ntau ntxiv rauv castable. Vim tias lub npog hluav taws xob ua haujlwm nyob rau hauv qhov kub thiab txias thiab cua txias thiab cua sov, cov xwm txheej thaum siv lub hau npog yog qhov hnyav heev. Yog hais tias lub siab alumina cib siv rau masonry, lub xub ntiag ntawm hluav taws xob qib qhov yuav yooj yim ua rau refractory bricks tev tawm. Txawm li cas los xij, lub qhov cub npog cov khoom siv ua los ntawm cov txheej txheem cement qis nrog ntxiv cov hlau fibers muaj thermal shock stability thiab tsis kam mus rau high-temperature yaj yaig.
Nyob rau hauv cov txheej txheem ntawm cov cement castable tsawg, ntxiv ib qho kev faib ua feem ntawm cov cua sov-resistant steel fibers tuaj yeem txhim kho cov kev ntxhov siab thiab lub zog ntawm cov castable, thiab cov hlau fiber ntau castable muaj thermal shock stability, tawg tsis kam, thiab tev tsis kam. Yuav ua tau zoo dua rau kev pab cuam lub neej ntawm lub qhov cub npog.
Tsis tas li ntawd, ntxiv cov hlau fibers rau cov khoom siv casting tuaj yeem txhim kho lub zog ntawm qhov nruab nrab thiab siab kub, thiab tseem txo qis qhov seem ntawm lub qhov cub npog tom qab cua sov. Vim lub complex smelting ib puag ncig, lub qhov cub hluav taws xob npog feem ntau catches hluav taws nyob rau hauv lub qhov hluav taws xob qib qhov chaw, thiab nws yog ib qho yooj yim mus tev tawm thaum lub sij hawm siv cov refractory cib. Ua rau cov refurbished furnace cover yuav siv tsis tau.
Qhov cuam tshuam ntawm lub tshuab hluav taws xob npog tsis muaj zog npaum li lub tshuab hluav taws xob npog. Cov txheej txheem sib piv ntawm cov cement qis thiab micro hmoov tshuab tuaj yeem siv rau kev tsim khoom, vim tias cov cement qis tuaj yeem txo cov calcium cov ntsiab lus ntawm cov castable, thiab tom qab siv lub voj voog ntev dua. Daim ntawv thov ntawm micro hmoov tshuab ua rau cov castable tsim los ntawm cov txheej txheem no ruaj khov nyob rau hauv nruab nrab thiab kub ua haujlwm. Ntxiv mus, thaum lub sij hawm tsim kho, lub zog thiab ruaj khov ntawm cov castable muaj zog dua vim qhov txo cov dej ntxiv.
