Dab tsi yog cov khoom siv zoo tshaj plaws rau lub qhov cub npog castables?
01. Siv ntau yam khoom siv
Muaj ntau ntau yam khoom siv rau lub qhov cub npogcastables. Nws tsis tuaj yeem xaiv cov khoom siv tiag tiag. Cov khoom tsim nyog tshaj plaws yog xaiv raws li qhov corrosion degree ntawm qhov sib txawv rauv kub.
Piv txwv li, lub qhov cub npog ntawm calcium carbide rauv tuaj yeem siv cov txheej txheem qis-cement npog castable, thaum lub qhov cub hluav taws xob npog yog tsim rau siv nrog steel fiber ntau rauv npog castables. Vim tias lub npog hluav taws xob ua haujlwm nyob rau hauv cov xwm txheej ntawm qhov kub thiab txias thiab cua sov sai, cov xwm txheej thaum siv lub tshuab ua kom sov yog qhov hnyav heev. Yogsiab alumina cibyog siv rau masonry, cov refractory bricks yuav yooj yim tev tawm vim hluav taws xob qhov. Txawm li cas los xij, lub qhov cub npog castable ua los ntawm cov cuab yeej siv qis-cement nrog ntxiv steel fibers tau zoo heev thermal poob siab thiab tsis kam mus rau high-temperature yaj yaig.
02. Ntxiv steel fiber ntau tuaj yeem txhim kho qhov kub thiab txias zog
Vim hais tias nyob rau hauv cov txheej txheem ntawm cov cement castables tsawg, ntxiv ib qho kev faib ua feem ntawm cov cua sov-resistant steel fibers tuaj yeem txhim kho qhov kev ntxhov siab ntawm cov castables thiab txhim kho lub toughness ntawm castable. Ntxiv mus, cov hlau fiber ntau castables muaj zoo thermal shock stability, cracking kuj thiab Peeling. Nws tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm lub qhov cub npog.
Tsis tas li ntawd, vim hais tias steel fiber ntau ntxiv rau castable, nws tuaj yeem txhim kho lub zog ntawm qhov nruab nrab thiab siab kub thiab txo qis qhov seem ntawm lub qhov cub npog tom qab cua sov. Vim yog qhov nyuaj smelting ib puag ncig ntawm lub qhov cub hluav taws xob npog, hluav taws kub feem ntau khiav tawm ntawm qhov chaw electrode, thiab nws yooj yim rau tev tawm thaum siv cov cib refractory. Yog li ntawd, lub refurbished furnace cover yuav siv tsis tau.
03.Cov khoom siv dab tsi?
Qhov cuam tshuam ntawm calcium carbide furnace cover tsis muaj zog npaum li cov hluav taws xob lub qhov cub npog. Nws tuaj yeem ua nrog cov txheej txheem sib piv ntawm cov cement qis thiab micro-hmoov thev naus laus zis, vim tias cov cement tsawg tuaj yeem txo cov calcium cov ntsiab lus ntawm cov castable, thiab tom qab kev pab cuam lub neej yuav ntev dua, thiab kev siv tshuab micro-powder, Dab tsi ntxiv, lub qhov cub npog castables uas tsim los ntawm cov txheej txheem no muaj kev ruaj ntseg ntawm qhov nruab nrab thiab siab kub, thiab thaum lub sij hawm tsim kho, cov dej ntxiv yog txo, ua rau cov castable muaj zog thiab ruaj khov.
04. Qhov kev ua tau zoo yog qhov zoo tshaj qhov siab ntawm alumina cib
Txawm hais tias nws yog ib qho qis-cement cub tawg npog castables los yog lub qhov cub npog castable nrog refractory steel fiber ntau technology, qhov kev ua tau zoo dua li ntawm high-alumina cib, vim hais tias cov cam khwb cia rauv cover muaj kev ncaj ncees thiab tsis muaj teeb meem nyob rau hauv lub refractory. cib masonry txheej txheem. Cib txuas cov qhov khoob. Nyob rau hauv ib txwm muaj xwm txheej, qhov tseem ceeb ntawm lub qhov cub npog npog yuav ua rau muaj kev pab cuam lub neej li ntawm 15% piv nrog kev siv cov cib refractory.
Txawm li cas los xij, qhov kev xaiv ntawm lub tshuab hluav taws xob qis qis siv cov castables lossis lub qhov cub npog castable nrog steel fiber ntau yog nyob ntawm qhov kub ntawm lub cub tawg, qhov zoo ntawm lub qhov cub npog, thiab qhov chaw siv.
