Lub tshuab nqus tsev kub kho cov cuab yeej sintering txoj kev

Txoj kev sintering yog ua ntej sinter ib co raw cov ntaub ntawv, crushed thiab sieve lawv, thiab ces sib tov nrog raw cov ntaub ntawv raws li ib tug tej yam kev faib ua feem, thiab ces mus los ntawm molding, ziab thiab tua. Lub hom phiaj ntawm cov khoom siv raw khoom ua ntej tua hluav taws yog hlawv tawm cov dej noo, cov organic impurities thiab sulfates decomposed gas, thiaj li yuav txo tau cov firing shrinkage ntawm cov khoom thiab xyuas kom meej qhov tseeb ntawm cov khoom sab nraud qhov ntev. Cov ntaub ntawv raw yuav tsum tau sieved tom qab crushing thiab sib tsoo, vim hais tias cov blanks yog graded los ntawm cov hmoov ntawm txawv particle qhov ntau thiab tsawg, uas muaj peev xwm xyuas kom meej packing nyob ze thiab tau ntom ntom.

Dab tsi yog lub zog ntawm cov khoom siv refractory rau cov khoom siv kho cua sov?

Cov khoom ntawm lub cev ntawm cov khoom siv refractory muaj xws li cov khoom siv, cov khoom siv thermal, cov khoom siv kho tshuab, cov khoom siv thiab cov khoom ua haujlwm.

Cov yam ntxwv ntawm cov khoom siv refractory muaj xws li porosity, bulk ntom, dej nqus, huab cua permeability, pore loj faib, thiab lwm yam.

Lub thermal zog ntawm cov ntaub ntawv refractory muaj xws li thermal conductivity, thermal expansion coefficient, tshwj xeeb tshav kub, tshav kub muaj peev xwm, thermal conductivity, thermal emissivity, thiab lwm yam.

Cov khoom siv ntawm cov khoom siv refractory muaj xws li compressive zog, tensile zog, flexural zog, torsional zog, shear zog, cuam tshuam lub zog, hnav tsis kam, creep, daim ntawv cog lus zog, elastic modulus, thiab lwm yam.

Kev ua haujlwm ntawm cov ntaub ntawv refractory muaj xws li refractoriness, load softening kub, reburning kab hloov, thermal shock kuj, slag kuj, acid kuj, alkali tsis kam, hydration kuj, CO corrosion kuj, hluav taws xob conductivity, oxidation kuj tos.

Kev ua haujlwm ntawm cov khoom siv refractory suav nrog kev sib xws, poob qis, fluidity, plasticity, cohesion, resilience, coagulation, hardening, thiab lwm yam.

Cov ntaub ntawv tshwj xeeb feem ntau siv hauv lub tshuab nqus tsev kho cua sov:

Cov ntaub ntawv tshwj xeeb feem ntau siv yog AZS cib, corundum cib, ncaj qha sib txuas magnesia chrome cib, silicon carbide cib, silicon nitride bonded silicon carbide cib, nitrides, silicides, sulfides, borides, carbides thiab lwm yam ntaub ntawv uas tsis yog-oxide refractory; Calcium oxide, chromium oxide, aluminium oxide, magnesium oxide, beryllium oxide thiab lwm yam ntaub ntawv refractory. Feem ntau siv thermal rwb thaiv tsev thiab cov ntaub ntawv refractory muaj xws li diatomite khoom, asbestos khoom, thiab thermal rwb thaiv tsev boards.
