I-oxidation yeukuthethelelwaIthinteka kakhulu ekubunjweni kwamakhemikhali kwensimbi evuthayo kanye nezinto zangaphakathi nangaphandle zendandatho yokushisa (efana nokwakheka kwegesi isithando somlilo, lokushisa lokushisa, njll.).
1) Ukwakheka kwamakhemikhali zezinto zensimbi
Inani lesikali se-oxide esakhiwe lihlobene kakhulu nokwakheka kwamakhemikhali. Okuphezulu kokuqukethwe kwekhabhoni kwensimbi, kwakhiwa isikali se-oxide, ikakhulukazi lapho okuqukethwe kwekhabhoni kudlula u-0.3%. Lokhu kungenxa yokuthi ngemuva kokuthi i-carbon i-oxidised, ungqimba wegesi we-monoxide (co) wenziwa ebusweni obungenalutho, odlala indima ekuvimbeleni i-oxifation eqhubekayo. Insimbi ye-Alloy ku-CR, NI, i-Al, Mo, iMo, ukufudumeza okwengeziwe lapho ukwakhiwa kwezinga kungaphansi, ngoba lezi zinto zazingu-oxidized, zingakha ungqimba, zingakha ungqimba ngaphezulu kwefilimu eliminyene le-oxide eliminyene, futhi futhi Insimbi isondelene ne-coefficie ethe xaxa yokunwebeka, futhi ifakwe ngokuqinile ebusweni, akulula ukuhlukana futhi iwe, ngakho-ke ukuvikela ezinye i-oxidation, ukuvikelwa. Insimbi engamelana nokushisa engavikeli insimbi iyinsimbi ye-alloy enezinto eziningi ezingenhla, futhi lapho okuqukethwe yi-ni no-cr ngensimbi kungu-13%? Ku-20%, cishe akukho ximation kwenzeka.
2) Ukwakheka kwegesi
Ukwakheka kwegesi yomlilo kuthonya elihle ekwakhekeni kweukuthethelelaIsikali, okufanayoUkukhokhiswa kwensimbiEsimweni esiphansi sokushisa, ukwakheka kwesilinganiso akufani, ephepheni le-oxidizing runce, ukwakheka kwesilinganiso kungcono kakhulu, kukhanya okukhanyayo, okulula ukususa; Kugesi ongathathi hlangothi (ikakhulukazi equkethe i-N2) kanye nokwehlisa igesi yesithando (equkethe i-CO, H2, njll.) Ukuze unciphise ukwakheka kanye nokususwa kwesikali se-oxide, ukunakwa kufanele kukhokhwe ekuphathweni kokwakheka kwegesi isithando esigabeni ngasinye sokushisa. Ngokuvamile, ukuthethelelwa kungaphansi kwe-1000 ℃, kanye negesi ye-oxidized isithando lapho kushisa, ngoba izinga lokushisa aliphezulu ngalesi sikhathi, inqubo ye-oxidation ayikhuli kakhulu, futhi isikali se-oxidation asikabi lula kakhulu, futhi isikali se-oxide sakhiwe kulula ukususa; Lapho amazinga okushisa edlula i-1000 ℃, ikakhulukazi esiteji esiphakeme sokushisa esiphethe, enciphisa igesi yomlilo noma igesi engathathi hlangothi kufanele isetshenziselwe ukunciphisa ukukhiqizwa kwesikali se-oxide.
Uhlobo lwegesi isithando somlilo esithandweni sokufudumeza flame kuya ngenani lomoya elinikezwe uphethiloli ngesikhathi sokuvutha. Uma i-coeffied ethe xaxa yomoya esithandweni somlilo inkulu kakhulu, ukulethwa komoya kukhulu kakhulu, igesi yomlilo i-oxidised, i-metal oxide isilinganiselo, uma i-coeffied yomoya engaphezulu, uma i-coeffied ye-air eyeqile, uma i-coeffied eyeqile esithandweni somlilo ingu-0.4? Ku-0,5, igesi yomlilo iyancishiswa, yakha umkhathi wokuvikela ukugwema ukwakheka kwesikali se-oxide futhi kufinyelelwe ukufudumala kwe-oxidation.

3) Ukushisa kokushisa
Izinga lokushisa lokushisa libuye libe yinto eyinhloko yokwakhiwa kwamazinga, okuphezulu kokushisa okufudumeza, i-oxidation enkulu kakhulu. Ku-570 ℃? Ngaphambi kuka-600 ℃, ubukele i-oxidation lihamba kancane, lisuka ku-700 ℃ isivinini se-oxidation sisheshise, siye ku-900 ℃? Ku-950 ℃, i-oxidation ibaluleke kakhulu. Uma isilinganiso se-oxidation sithathwa njenge-1 ku-900 ° C, 2 ku-1000 ° C, 3.5 ngo-1100 ° C, no-7 ° C, kwandiswa amahlandla ayisithupha.
4) Isikhathi sokushisa
Isikhathi eside sokushisa kokuthethelelwa kwegesi oxidizing gesi esithandweni somlilo, kukhunjulwa okukhulu kwe-oxidation, futhi kwakhiwa kakhulu isilinganiselo se-oxide, ikakhulukazi esigabeni sokushisa samazinga okushisa aphezulu, ngakho-ke isikhathi sokushisa kufanele sincishiswe ngangokunokwenzeka , ikakhulukazi isikhathi sokushisa nesikhathi sokubamba ngokushisa okuphezulu kufanele kufinyezwe ngangokunokwenzeka.
Ngaphezu kwalokho, imali ekhokhwayo ekushiseni okuphezulu ayigcini nje kuphela esithandweni somlilo, kodwa nasezinhlelweni ezazikhokhile, yize izinga lokushisa le-oxide lise liphezulu, lizobe liphakeme kabili, kodwa Izinga le-oxidation kancane kancane liba buthaka ngokuncipha kokushisa kwe-billet.
