Waa maxay lebenkii neefsashada caato ah

Lebiska hawo-mareenka laleeliyaha ah waa badeecad cusub oo leh cimri dheer, keydinta tamarta iyo yareynta isticmaalka, oo leh qaab dhismeed macquul ah, xasilloonida kuleylka wanaagsan, iska caabbinta nabaad-guurka, iska caabinta nabaad-guurka, iyo iska-caabbinta dheef-shiidka cimri dherer adeeg Sug daqiiqad. Badanaa waxaa loo isticmaalaa birta samaynta birta, saldhigga iyo qaybaha kale.

Kobcinta iyo adeegsiga laundarka laf-dhabarka lebenkii neefsashada oo loogu talagalay laalaad la sifeeyay oo baaxad leh: Si loo buuxiyo shuruudihii laad sifeysan ee baaxadda lahaa ee lebenkii neefsashada ahaa, iyada oo loo marayo hab farsamo sida kobcinta qaaciddada iyo dabka heerkulka sare, waxqabadka iyo isticmaalka natiijooyinka ayaa si guul leh loo soo saaray. Lebenkii corundum-spinel lebenkii neefsashada ahaa ee lebenkii neefsashada ahaa ee laydhka ahaa ee chromium corundum. Lebenka neefsashada ee laalaadda wuxuu ka samaysan yahay corundum saxan sida maaddada granular, corundum cad oo la isku daray sida budo wanaagsan, wuxuuna ku daray 6% sibidh saafi ah oo aluminate ah, 5% Active α-Al2O3 micropowder iyo 8% spinel, oo lagu daray qaddar ku habboon oxide chromium iyo yareynta biyaha wakiilka, ka dib gariirkii sameynta, qallajinta, ilaalinta kuleylka 1630 ° C in ka badan 3 saacadood. Lebenkii hawo-mareenka ahaa ee laalaabka ahaa ayaa loo adeegsadaa galley weyn oo la safeeyey si loo helo Si miro-dhal leh loogu qanco.

Argon-ka hoose ee argon afuufaya leben hawo-dul-marin kara ayaa qaadata alaab ceyriin ah oo isku-dhafan oo isku-dhafan, shaxanka ayaa horay loo wada-milled oo la isku daray, iyo qaar ka mid ah alaabta ceyriinka ah ayaa si toos ah looga keenay dibadda, qoondayn macquul ah, iyo wax-soo-saar si adag loo xakameeyay si waafaqsan oo leh shuruudaha farsamada casriga ah ee caalamiga ah. Badeecadu waxay leedahay faa’iidooyinka xoogga sare, iska caabbinta nabaad -guurka, iska caabinta nabaad -guurka, iska -caabbinta gelitaanka, iyo nolosha adeegga dheer.

Tilmaamayaasha jirka iyo kiimikada ee alaabta: Al2O3% ≥95.0 Cr2O3% ≥3.0, porosity muuqda:% ≤16.0, cufnaanta jumlada: g/cm3 ≥3.20, heerkulka caadiga ah ee cadaadiska cadaadiska: MPa 110 ° C ≥60.0, 1500 ° C ≥100.0, 1600 ° C ≥120.0. Heerkulka sare xoogga dabacsanaanta: MPa 1400 ° C, 30min ≥10.0.

Part Isticmaal qayb: dharbaaxada hoose ee dhalada.

Method Qaabka dhismaha: dhoobada dabka si siman ugu marmariso, rakibidduna waa mid deggan.
