High-aluminium refractory cov ntaub ntawv: xws li high-alumina cib, high-alumina ceramic fibers, thiab lwm yam. High-aluminium cov ntaub ntawv muaj cov yam ntxwv ntawm high-temperature zog thiab zoo hnav tsis kam, thiab feem ntau yog siv nyob rau hauv metallurgy thiab kev tsim kho. .
Silicon-carbon refractory cov ntaub ntawv: xws li silicon-carbon bricks, silicon-carbon ceramic fibers, thiab lwm yam. Silicon carbon cov ntaub ntawv muaj zoo heev kub kuj thiab thermal shock kuj thiab yog dav siv nyob rau hauv molten hlau kho thiab refractory linings.
Tsis tas li ntawd, muaj siliceous (silicate oxide), aluminium silicate, corundum magnesium, magnesium calcium, aluminium magnesia, magnesia silicon, carbon composite refractory cov ntaub ntawv, zirconium refractory cov ntaub ntawv, cov ntaub ntawv tshwj xeeb refractory, thiab lwm yam.
2. Lub cev muaj zog
Cov khoom siv lub cev ntawm cov khoom siv refractory muaj xws li cov khoom siv hluav taws xob, cov khoom siv thermal, cov khoom siv kho tshuab, kev ua haujlwm thiab kev ua haujlwm. Ntawm lawv, cov khoom muaj xws li porosity, ntim ntom ntom, dej nqus, huab cua permeability, pore loj faib, thiab lwm yam.; Cov khoom siv thermal muaj xws li thermal conductivity, thermal expansion coefficient, tshwj xeeb tshav kub, tshav kub muaj peev xwm, thermal conductivity coefficient, thermal emissivity, thiab lwm yam.; mechanical zog muaj xws li Compressive zog, tensile zog, flexural zog, torsional zog, shear zog, cuam tshuam lub zog, hnav tsis kam, creep khoom, bonding zog, elastic modulus, thiab lwm yam. Kev siv cov kev ua tau zoo suav nrog refractoriness, load softening kub, Reburning kab hloov, thermal shock kuj, slag kuj, acid kuj, alkali tsis kam, hydration kuj, CO yaig kuj, conductivity, oxidation kuj, thiab lwm yam.
3. Daim ntawv thov
Cov ntaub ntawv refractory yog siv dav hauv metallurgy, tshuaj lom neeg kev lag luam, kev tsim kho, lub zog thiab lwm yam kev lag luam los tsim cov refractory furnaces, refractory linings, refractory rwb thaiv tsev cov ntaub ntawv, thiab lwm yam. machinery, boilers, lub teeb kev lag luam, hluav taws xob fais fab thiab lwm yam teb. Lawv yog cov khoom siv tseem ceeb los xyuas kom meej tias kev ua haujlwm ntau lawm thiab kev tsim kho thev naus laus zis ntawm cov kev lag luam saum toj no tau hais tseg.
4. Txoj Kev Loj Hlob
Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, cov ntaub ntawv refractory yuav txhim kho nyob rau hauv cov kev taw qhia ntawm lub teeb yuag, kev ua haujlwm siab, thiab kev tiv thaiv ib puag ncig yav tom ntej. Cov thev naus laus zis tshiab xws li nanotechnology thiab biomass cov ntaub ntawv yuav txuas ntxiv txhawb kev tshawb fawb thiab kev tsim cov khoom siv refractory, ua rau lawv ua lub luag haujlwm ntau dua hauv ntau yam. Nyob rau tib lub sijhawm, cov khoom siv refractory customized kuj tseem yuav dhau los ua qhov kev txhim kho yav tom ntej rau cov ntawv thov sib txawv.
