Chrome Corundum Castable
Khoom Description
Cov khoom tseem ceeb ntawm chromium corundumrefractory castablemuaj xws li txhuas oxide, chromium oxide thiab magnesium oxide. Ntawm lawv, tus nqi ntawm chromium oxide ntxiv tuaj yeem cuam tshuam rau thaj chaw tshwj xeeb, acid corrosion kuj thiab thermal shock kuj ntawm chromium corundum. Kev ua haujlwm kub ntawm chromium corundum castable yog qhov zoo heev thiab tuaj yeem siv tau ntev hauv qhov chaw kub siab tshaj 1500C yam tsis ua haujlwm.
Chrome corundum castable yog ib qho kev ua tau zoo corundum castable feem ntau yog ua los ntawm high-purity corundum li aggregate thiab hmoov, tov nrog ib tug tsim nyog tus nqi ntawm industrial chromium oxide, aluminate cement raws li ib tug binding neeg sawv cev, thiab ntau yam admixtures. Castables tuaj yeem muab faib ua ob hom: hom zoo tib yam thiab hom qis qis. Tsawg-expansion castables muaj qis dua expansion coefficient, uas tuaj yeem txo qhov kev puas tsuaj los ntawm thermal expansion tshwm sim los ntawm qhov kub thiab txias.

Cov txheej txheem kev npaj ntawm chromium corundum castable muaj xws li hmoov batching, npaj molding slurry, casting thiab ziab. Ntawm lawv, qhov fineness thiab dispersion ntawm cov hmoov muaj kev cuam tshuam zoo rau qhov zoo ntawm castable.
Kev tsim cov chrome corundum refractory castable muaj kev sib xyaw ua ke ntawm cov khoom siv raw khoom kom ua tiav cov khoom xav tau thiab cov khoom. Cov sib tov yog ces tov nrog binders thiab additives, cam khwb cia rau hauv cov duab xav tau, thiab kho los ntawm kev tswj kom qhuav thiab tua cov txheej txheem.
Khoom nta
High Temperature Resistance: Chrome corundum castable qhia tshwj xeeb tiv thaiv rau qhov kub thiab txias, tswj kev ua haujlwm ruaj khov thiab ruaj khov hauv cov cua kub hnyav.
Corrosion Resistance: Nws cov tshuaj muaj pes tsawg leeg muaj kev tiv thaiv corrosion los ntawm slag, tshuaj, thiab thermal shock, ua kom lub neej ntev kev pab cuam nyob rau hauv ib puag ncig hnyav.
Kev hnav zoo heev: Lub castable showcases zoo kawg li tiv thaiv hnav thiab yaig, ua rau nws tsim nyog rau cov ntawv thov raug puas tsuaj thiab kev ntxhov siab.
Cov txheej txheem tsim khoom:
Cov txheej txheem tsim khoom muaj kev npaj ua kom zoo thiab sib xyaw ntawm cov khoom siv raw. Cov txiaj ntsig sib xyaw yog ces muab pov rau hauv cov duab los yog hauv ob sab phlu, ua raws li kev tswj kev kho thiab tua ntawm qhov kub siab, ua kom muaj cov qauv ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom.
Khoom Advantage
Slag kuj: Chrome corundum refractory castable yog ua los ntawm ultrafine hmoov thiab tsis tshua muaj cement technology thiab yog dav siv nyob rau hauv lub teb ntawm steelmaking. Slag kuj yog qhov ua tau zoo ntawm chrome corundum refractory castables. Thaum lub sij hawm tsim khoom, cov tuam ntxhab yuav tsum tau kho cov dej-txo cov neeg sawv cev ntxiv thiab retardant raws li qhov sib txawv ntawm cov neeg siv khoom thiab lub sijhawm sib txawv.
Thaum ntxiv chromium oxide, qhov me me ntawm cov hmoov refractory yuav tsum tau kho. Qhov sib txawv ntawm qhov loj me me yuav cuam tshuam rau kev ua haujlwm ntawm chromium corundum castables. Ua kom tus nqi ntawm Cr2O3 tuaj yeem txhim kho cov slag tsis kam ntawm cov castable, tshwj xeeb tshaj yog cov tsis kam mus rau slag nkag.
Enhanced Durability: Lub castable lub superior tsis kam rau thermal stress, tshuaj corrosion, thiab hnav ua kom lub neej ntev kev pab cuam thiab txo cov kev tu ncua.

Khoom Disadvantages
Qhov tsis zoo ntawm chrome corundum castable:
Tom qab cov tshuaj tiv thaiv ntawm Cr2O3 thiab AL2O3, cov khoom siv txhuas-chromium yuav raug tsim. Thaum reacting nrog rau lwm yam impurities, ib tug chromium-muaj iav theem yuav tsim, uas yuav tsim ib tug kob duab thiab sau ntawm chromium corundum crystals. Lub viscosity loj thiab tuaj yeem tiv thaiv kev nkag mus ntawm molten slag.
Nws tsis yog tias ntau chromium oxide ntxiv, qhov zoo dua cov slag kuj yuav. Yog tias koj ntxiv ntau dhau lawm, qhov txhaum yuav tev tawm raws li qhov kev txiav txim ntawm thermal cov tshuaj tiv thaiv quab yuam, thiab nws yooj yim los thaiv cov cua raws, yog li nws yog qhov zoo tshaj rau ntxiv 3-6%.
