thabatha izitena eziphefumlayo njengomzekelo, chaza ngokufutshane ulwazi olusisiseko lwezinto eziphikisayo

Ukuthatha isitena njengomzekelo, eli nqaku lixubusha ulwazi olusisiseko lwee-refractories ezivela kwiinkalo ezine: i-thermal conductivity, umthamo wokushisa okhethekileyo, i-refractoriness, kunye nobushushu bokunciphisa umthwalo.

(Umfanekiso) I-Refractory

I-Thermal conductivity ye-refractory materials: I-Thermal conductivity ibonisa i-thermal conductivity ye-substance. I-conductivity enkulu ye-thermal, ingcono umqhubi we-thermal. Ubuninzi bezitena ezinomoya we-ladle zikhulu, kwaye i-thermal conductivity ihambelana ngokuhambelanayo.

Umthamo wobushushu obuthile wemathiriyeli ye-refractory: Umthamo wobushushu obuthile umele ukufunxa ubushushu okanye amandla okuphelisa ubushushu bento. Okukhona ubukhulu besakhono esithile sobushushu, kokukhona bomelela bufunxa ubushushu obuhambelanayo okanye amandla okuphelisa ubushushu. Umthamo wokushisa othe ngqo wezitena ezinomoya-moya uhambelana nexesha lokubhaka kunye nokupholisa.

Ukuchaswa kwezinto ezichasayo: Njengoko kukhankanywe kwinqaku elidlulileyo, isalathiso sobugcisa esidibanisa ukubunjwa kweekhemikhali, ukusabalalisa, umlinganiselo kunye ne-viscosity yesigaba samanzi esiqulethwe kwizinto eziphathekayo. I-Refractoriness yenye yezibonakaliso ezibalulekileyo zezinto eziphikisayo. Xa zisetyenziswa, izinto eziphikisayo kufuneka zikwazi ukumelana nobushushu obuphezulu bendawo yokusetyenziswa. Kwizitena eziphefumulayo, ukuba ukushisa kwentsimbi etyhidiweyo kuphezulu kakhulu, akuyi kuchaphazela kuphela ubomi bezitena eziphefumulayo, kodwa nokuba kubangele ukuvuza okukhulu. ingozi.

Iqondo lokushisa lokunciphisa umthwalo wezinto eziphikisayo: Ibonisa ukuxhathisa kwezinto kwiqondo lokushisa eliphezulu kunye nomthwalo ngexesha elifanayo. Iimveliso ezixhathisayo zinamandla aphezulu okucinezela kwiqondo lobushushu begumbi, kodwa emva kokulayishwa kumaqondo obushushu aphezulu, ziya kukhubaza kwaye zinciphise amandla azo oxinzelelo.

(Umfanekiso) Igalelwe kwiziko lentsimbi eliqhumayo
