Raws li ib qho ntawm cov khoom tseem ceeb,siab alumina castablesmuaj cov khoom zoo heev hauv qhov chaw huab cua xws li qhov kub thiab txias, corrosion thiab hnav, ua rau lawv xaiv zoo tshaj plaws rau cov khoom siv thiab kev tsim vaj tsev.Dab tsi yog qhov zoo ntawm high-aluminium refractory castables?
Raws li cov khoom siv refractory zoo heev, qhov zoo tshaj plaws ntawm high alumina castables yog nyob rau hauv nws cov hluav taws kub-resistant kev ua tau zoo. Nws lub peev xwm los tswj kev ruaj ntseg nyob rau hauv qhov kub thiab txias yog feem ntau vim nws cov ntsiab lus aluminium siab. Cov yam ntxwv no tso cai rau nws tiv taus qhov kub thiab txias yaig thiab tsis yooj yim rau deformation lossis melting, yog li ua kom muaj kev ruaj ntseg thiab ruaj ntseg ntawm cov txheej txheem kev lag luam.
Tsis tas li ntawd, siab alumina castables kuj muaj thermal shock stability thiab corrosion kuj. Ntawm qhov kub thiab txias, nws tuaj yeem tiv taus qhov cuam tshuam ntawm thermal stress thiab tiv thaiv kev tawg lossis tev tawm los ntawm kev hloov pauv kub tam sim ntawd. Nyob rau tib lub sijhawm, nws tseem tuaj yeem tiv taus qhov yaig ntawm cov roj kub kub thiab cov khoom molten, tswj nws cov qauv kev ncaj ncees thiab kev ua haujlwm.
High-alumina refractory castables tau pom zoo tiv thaiv hlau, slag thiab tshuaj tua kab mob. Cov yam ntxwv no ua rau lawv txaus nyiam nyob rau hauv high-temperature industrial teb. Los ntawm nws cov tshuaj lom neeg muaj pes tsawg leeg thiab cov qauv ntawm lub cev, cov khoom siv no zoo tiv thaiv kev yaig ntawm corrosive xov xwm, yog li ncua kev pab cuam lub neej ntawm cov khoom.
Cov ntsiab lus ntawm aluminium siab nyob rau hauv siab alumina castables muab nws cov tshuaj lom neeg ruaj khov thiab tuaj yeem tiv taus qhov yaig ntawm ntau yam tshuaj lom neeg. Nyob rau tib lub sijhawm, nws qhov ntom ntom microstructure tseem tiv thaiv kev nkag mus ntawm cov hlau molten thiab dross, ntxiv dag zog rau nws cov corrosion kuj.
High alumina castables tau pom tias lawv lub zog txawv tshaj plaw nyob rau hauv high-temperature thiab high-pressure ua hauj lwm ib puag ncig vim lawv zoo heev hnav tsis kam. Kev hnav tsis kam ntawm cov khoom siv no los ntawm nws cov khoom tshwj xeeb ntawm lub cev thiab tshuaj lom neeg, uas tuaj yeem tswj tau qhov smoothness thiab kev ncaj ncees ntawm cov khoom nto nyob rau hauv lub sij hawm ntev kev kub ntxhov.
Kev hnav zoo heev tsis tsuas yog txhais tau hais tias siab alumina castables muaj lub neej ua haujlwm ntev nyob rau hauv kev ua haujlwm hnyav, tab sis kuj txhais tau tias nws tuaj yeem txo cov khoom siv poob qis thiab cov nqi kho mob vim hnav thiab tsim kua muag. Cov yam ntxwv no ua rau high-aluminium refractory castables ib qho khoom siv tseem ceeb hauv kev lag luam kub kub, pab txhim kho cov khoom siv thiab ua kom ruaj khov ntawm cov kab ntau lawm.
Yog li ntawd, rau cov khoom siv uas yuav tsum tau ua haujlwm nyob rau hauv qhov kub thiab txias ib puag ncig, xaiv high alumina castables raws li cov khoom siv rau cov khoom tseem ceeb yog undoubtedly ib tug ntse thiab kev txiav txim siab. Nws qhov hnav-tiv taus kev ua tau zoo yuav muab lub zog lav rau kev ua haujlwm ruaj khov mus sij hawm ntev ntawm cov cuab yeej siv thiab ua rau muaj txiaj ntsig zoo rau kev tsim khoom thiab cov txiaj ntsig kev lag luam ntawm kev lag luam.
