Loluphi olona cingo lokufudumeza into?

Ukukhethwa kocingo oluhle kakhulu kwisixhobo sokufudumeza kuxhomekeke kwiimfuno ezithile zesicelo. Nangona kunjalo, ezinye izinto eziqhelekileyo ezisetyenziselwa ukufudumeza izinto ziquka:

1. Ingxubevange ye-nickel-chromium: Ingxubevange ye-nickel-chromium isetyenziswa kakhulu kwizinto zokufudumeza ngenxa yokumelana kwayo okuphezulu, ukumelana ne-oxidation elungileyo, kunye nokumelana nobushushu obuphezulu. Ngokuqhelekileyo zisetyenziswa kwizixhobo zasendlini ezifana ne-toasters, izomisi zeenwele, kunye nee-oveni.

2. I-Kanthal: I-Kanthal i-iron-chromium-aluminium alloy eyaziwa ngokuba namandla aphezulu okushisa, ukuchasana kakuhle kwe-oxidation, kunye nobomi obude benkonzo. Isetyenziswa ngokuqhelekileyo kwizicelo zokufudumeza kwimizi-mveliso ezifana nee-kilns, ii-ovens kunye nee-ovens zamashishini.

3. I-Tungsten: Eyaziwa ngokuba yindawo yokunyibilika ephezulu kakhulu, i-tungsten isetyenziselwa izicelo ezifuna ukushisa okuphezulu kakhulu, njengeziko lobushushu obuphezulu kunye neenkqubo ezikhethekileyo zoshishino.

4. I-Molybdenum: I-Molybdenum yenye into enomgangatho ophezulu wokunyibilika kunye nokuchasana okulungileyo kwi-corrosion kunye ne-oxidation, okwenza ukuba ifaneleke kwizinto zokushisa eziphezulu zokushisa kwizicelo ezikhethekileyo.

Olona cingo lulungileyo lwento yokufudumeza luxhomekeke kwizinto ezifana nobushushu obufunwayo bokusebenza, indawo eza kusetyenziswa kuyo, kunye neemfuno ezithile zokufudumeza kwesicelo. Isixhobo ngasinye sineenzuzo kunye nokunciphisa, ngoko ke ukhetho kufuneka lusekelwe kwiimfuno ezithile zokusetyenziswa okujoliswe kuyo kwisixhobo sokufudumala.

Ngaba imolybdenum ngumqhubi olungileyo wobushushu?

I-Molybdenum ithathwa njengomqhubi olungileyo wobushushu, nangona ingaqhubeki ubushushu ngokufanelekileyo njengezinye iintsimbi ezifana nobhedu okanye i-aluminium. I-thermal conductivity ye-molybdenum kwiqondo lokushisa malunga ne-138 W / m · K, engaphantsi kobhedu (malunga ne-401 W / m · K) kunye ne-aluminium (malunga ne-237 W / m · K).

Nangona kunjalo, i-thermal conductivity ye-molybdenum isephezulu kakhulu xa kuthelekiswa nezinye izinto ezininzi, ngakumbi kumaqondo aphezulu. Oku kwenza i-molybdenum ibe yinto efanelekileyo yokukhetha izicelo ezifuna ukutshintshwa kobushushu obuphezulu, njengezinto zokufudumeza, ii-furnaces eziphezulu kunye nezinye iinkqubo zokulawula ukushisa.

Ukongeza kwi-thermal conductivity, i-molybdenum inezinye izinto ezixabisekileyo ezifana neqondo eliphezulu lokunyibilika, ukuchasana ne-oxidation, kunye namandla afanelekileyo omatshini kumaqondo aphezulu okushisa, okwenza kube yinto eguquguqukayo kwizinto ezahlukeneyo zokushisa okuphezulu.

Luyintoni unyango lobushushu lwemolybdenum?

I-Molybdenum ihlala iphathwa ngokutshisa ukuphucula iimpawu zayo zomatshini kunye nokunciphisa uxinzelelo lwangaphakathi. Inkqubo yonyango lobushushu lwemolybdenum ibandakanya ukufunxa, ukufudumeza okulawulwayo kunye nenkqubo yokupholisa. Amanyathelo athile onyango lobushushu kwimolybdenum angabandakanya:

1. Ukufakwa kweAnealing: I-Molybdenum idla ngokufakwa kumaqondo obushushu aphezulu, ngokuqhelekileyo kuluhlu lwe-1,800 ukuya kwi-2,200 degrees Celsius (3,272 ukuya kwi-3,992 degrees Fahrenheit). Izinto eziphathekayo zigcinwe kule qondo lokushisa ixesha elithile lokuvumela ukuphindaphinda kunye nokukhula kwengqolowa, okunceda ukukhulula uxinzelelo lwangaphakathi kunye nokuphucula i-ductility.

2. Ukupholisa okulawulwayo: Emva kwenkqubo yokuqhawula, i-molybdenum ipholisa ngokukhawuleza kwiqondo lokushisa legumbi ngendlela elawulwayo ukukhusela ukubunjwa koxinzelelo olutsha lwangaphakathi kunye nokugcina i-microstructure efunwayo.

Iiparamitha ezithile zenkqubo yokunyanga ukushisa, kubandakanywa ukushisa, ubude kunye nesantya sokupholisa, kunqunywe ngokusekelwe kwiimpawu ezifunekayo zomatshini kunye neemfuno ezithile zesicelo.

Ngokubanzi, unyango olushushu lwe-molybdenum lujolise ekwandiseni i-microstructure yayo kunye neempawu zoomatshini ukuqinisekisa ukufaneleka kwayo kwizicelo zokushisa eziphezulu ezifana nokuveliswa kwezinto zokufudumeza, amacandelo eziko kunye nezinye izixhobo ezikhethekileyo zoshishino.
