Yintoni iDeoxidizers?

Iideoxidizers Zizongezo ezibalulekileyo ekwenzeni intsimbi, ngokuyintloko zinikwe umsebenzi wokususa ioksijini enyibilikisiweyo kwintsimbi enyibilikisiweyo. Ioksijini ekwintsimbi inokukhokelela kwiziphumo ezingathandekiyo njengokubunjwa kweeoksidi, ezibangela ubuqhophololo, ukuncipha kwe-ductility, kunye nezinye iziphene ezichaphazela umgangatho kunye nokusebenza kwemveliso yentsimbi yokugqibela. Ukhetho olufanelekileyo i-deoxidizer ibalulekile ekulawuleni umthamo wokugqibela weoksijini kunye nokuphembelela iimpawu zentsimbi.

Kutheni i-Deoxidation iyimfuneko?

Ubukho be-oksijini kwinsimbi etyhidiweyo bubumba i-iron oxides (i-FeO), eyonakalisa iimpawu zomatshini kunye nomgangatho opheleleyo wentsimbi egqityiweyo. Ezi oksidi zingabangela ukubandakanywa, okukhokelela ekunciphiseni amandla, ukuqina, kunye nokuxhamla. Isebenza ukukhutshwa kweoksijini Ngoko ke, kubalulekile ukuqinisekisa ukuba intsimbi ihlangabezana neenkcukacha ezifunekayo kwisicelo sayo. Ngaphandle kokufanelekileyo i-deoxidizer Ukongeza, intsimbi ingabonakalisa i-porosity, ukuqhekeka, kunye nokunciphisa ukunyameka kokukhathala.

Iintlobo zeeDeoxidizers ezisetyenziswa kwiMveliso yeNsimbi

iAluminiyam (Al)

IAluminiyam inamandla i-deoxidizer, ukusabela ngamandla nge-oksijini ukwenza i-aluminium oxide (Al2O3). Le oxide ayinyibiliki kwintsimbi kwaye ithande ukudada ngaphezulu, ivumela ukususwa lula. Aluminiyam iideoxidizers zisetyenziswa ngokubanzi kwaye zisebenza ngempumelelo ekufumaneni amanqanaba aphantsi oksijini. Nangona kunjalo, i-aluminiyam eninzi inokukhokelela ekubunjweni kwe-aluminium nitride inclusions.

Isilicon (Si)

Isilicon yenye isetyenziswa ngokuqhelekileyo i-deoxidizer, ukusabela nge-oksijini ukwenza i-silica (SiO2). I-silicon idla ngokusetyenziswa ngokudibeneyo nezinye iideoxidizers ukuphucula ukusebenza kakuhle. Ukusebenza kakuhle kwesilicon njenge i-deoxidizer iphenjelelwa bubushushu kunye nobukho bezinye izinto.

IManganese (Mn)

IManganese ikwasebenza njenge i-deoxidizer, nangona ingaphantsi kwamandla kune-aluminiyam okanye i-silicon. Ihlala isetyenziswa ngokudibeneyo nezinye iideoxidizers ukuqhubela phambili ukunciphisa umxholo we-oksijeni kunye nokuphucula iimpawu zensimbi. IManganese ikwadlala indima ekuphuculeni ukomelela kwentsimbi nokusebenza kwayo.

Ezinye iiDeoxidizers

Ezinye izinto, ezifana ne-titanium (Ti), i-zirconium (Zr), kunye ne-calcium (Ca), zingasetyenziswa njenge iideoxidizers kumabakala athile entsimbi. Ukhetho lwabo luxhomekeke ekubunjweni kwensimbi efunwayo, inqanaba le-oksijini elifunekayo, kunye neendleko ezipheleleyo zenkqubo. Ukhetho luhlala lusekelwe kwibhalansi yeendleko, ukusebenza kakuhle, kunye nefuthe kwiimpawu zetsimbi ezibangelwayo. Ngokomzekelo, i-titanium iyaziwa ngokukwazi kwayo ukususa i-nitrogen ngaphezu kwe-oxygen.

Izinto ezichaphazela ukhetho lwe-Deoxidizer kunye nesicelo

Ukukhethwa kweyona nto ilungileyo i-deoxidizer kunye nendlela yokusetyenziswa kwayo ixhomekeke kwizinto ezininzi ezibalulekileyo, kuquka:

• Ibakala elifunwayo lensimbi kunye neemfuno zalo ezithile.
• Uhlobo lwenkqubo yokwenza insimbi esetyenziswayo (umzekelo, isithando somlilo esisisiseko se-oksijeni (BOF), isithando sombane se-arc (EAF)).
• Indleko-esebenzayo ye i-deoxidizer.
• Inqanaba elifunwayo lokususwa kwe-oxygen.
• Ithuba lokusekwa kokubandakanywa.

Impembelelo ye-Deoxidation kwiiPropati zeNsimbi

Iyasebenza ukukhutshwa kweoksijini ichaphazela kakhulu iipropati zentsimbi yesiphumo, ekhokelela kuphuculo kwi:

• Amandla
• I-Ductility
• Ukuqina
• Ukuweldability
• Ukumelana nokudinwa
• Ukuqulunqwa

Ayonelanga ukukhutshwa kweoksijini, ngokuchaseneyo, kunokubangela insimbi engaphantsi kunye nomgangatho oncitshisiweyo kunye neempawu ezingamkelekanga zomatshini.

Ukuqukumbela

Ukukhetha kunye nokusebenzisa ngokufanelekileyo iideoxidizers kubalulekile ekwenzeni intsimbi ukuze kuphunyezwe umgangatho ophezulu wentsimbi kunye nokusebenza. Ukhetho lwe i-deoxidizer kuxhomekeke kwizinto ezahlukeneyo, ezifuna ukuphononongwa ngenyameko kweendleko, ukusebenza kakuhle, kunye nefuthe elibangelwa kwiipropati zentsimbi. Ukuqonda okunzulu kwentsebenziswano phakathi iideoxidizers kunye nenkqubo yokwenza intsimbi iyimfuneko ekuveliseni iimveliso zetsimbi eziphezulu.
