I-Anealing yinkqubo yokunyanga ubushushu kwimibhobho edityanisiweyo yensimbi engenasici.Injongo yalo kukuphelisa uxinzelelo olushiyekileyo, ukuzinzisa imilinganiselo, kunye nokunciphisa ukuthambekela kokuguqulwa kunye nokuqhekeka.

Yintoni annealing 2205 umbhobho steel stainless?

Ngombhobho oveliswa ngumsebenzi obandayo, i-carbide precipitation, i-lattice defects, kunye nesakhiwo esingahambelaniyo kunye nokubunjwa kuya kubangela ukuxhathisa kwe-corrosion yensimbi engenasici.Ngeli xesha, unyango lwe-annealing (okanye unyango lwesisombululo) luyafuneka.

Kutheni le nto i-2205 ifakwe umbhobho wentsimbi engatyiwayo?

Ukunciphisa ubulukhuni bentsimbi kunye nokuphucula iplastiki ukuququzelela ukusika kunye nokulungiswa kwe-deformation kubanda

Ukucoca iinkozo, i-homogenize isakhiwo sensimbi kunye nokubunjwa, ukuphucula iimpawu zetsimbi okanye ukulungiselela unyango olulandelayo lobushushu

Ukuphelisa uxinzelelo lwangaphakathi olushiyekileyo kwintsimbi ukukhusela i-deformation kunye nokuqhekeka.

2205 inkqubo yensimbi engenasici

Kwimveliso, inkqubo ye-annealing isetyenziswa ngokubanzi.Ngokweenjongo ezahlukeneyo zokufunxa ezifunwa sisicwecwe sokusebenza, kukho iindlela ezahlukeneyo zokutywina, ezidla ngokusetyenziswa kukuthomalalisa uxinezeleko, ukuthomalalisa ngokupheleleyo kunye nokuqhobosha ngokulinganayo.

Ukuphelisa uxinzelelo.Isixhobo esixhaphakileyo sokuthomalalisa uxinzelelo lwetyhubhu yensimbi engenasici sisithando somlilo esiqhubekayo esiqaqambileyo setyhubhu yentsimbi engatyiwayo, eluhlobo lweziko lomlilo eliqaqambileyo.Umthombo wegesi okhuselayo wamkela isithando somlilo se-ammonia kwaye uxhotyiswe ngesixhobo sokucoca igesi. I-Hangao Tech (i-SEKO Machinery) yenze utshintsho lwesakhiwo se-muffle furnace, isusa indlela yokuhanjiswa kwebhanti ye-mesh kwaye endaweni yayo ngokuqhubekayo i-roller ye-tube enye ehambisa emgceni.Isixhobo sineempawu zolawulo oluphambili, ukonga amandla okumangalisayo, ukugcinwa okufanelekileyo, njl. njlImibhobho yensimbi engenasici ephathwa ngobushushu ngokusebenzisa yethu ugcino lobushushu umbhobho wentsimbi engenaziko eliqaqambileyo lomlilo yokunciphisa i-deformation kwaye iqinisekisa i-ellipticity yemibhobho.

Imitya yensimbi engenasici icwangciswe ngokulinganayo kwi-rack yokutya, ithunyelwe kwiziko lokutshisa ngebhanti lokuhambisa, ifudunyezwe kwi-1050-1080 ℃ phantsi kokhuseleko lomoya olawulekayo, kwaye emva koko igcinwe ixesha elifutshane, zonke ii-carbides ziyakwazi. zinyibilike ezikweni elivutha umlilo.Kwisakhiwo se-austenite, kwaye emva koko ipholile ngokukhawuleza ukuya ngaphantsi kwe-350 ° C, isisombululo esiqinileyo esiphezulu, oko kukuthi, isakhiwo se-unidirectional unidirectional austenite, sinokufumaneka.

Ikhutshwe ngokupheleleyo.Isetyenziselwa ukucokisa ulwakhiwo olurhabaxa kakhulu oluneempawu ezimbi zoomatshini emva kokuphosa, ukubunjwa kunye nokuwelda kwentsimbi yekhabhoni ephakathi kunye nephantsi.Fudumeza i-workpiece kwiqondo lobushushu le-30-50 ° C ngaphezu kweqondo lokushisa apho yonke i-ferrite iguqula ibe yi-austenite, ibambe ixesha elithile, kwaye ipholile ngokukhawuleza ngesithando somlilo.Ngethuba lenkqubo yokupholisa, i-austenite iguqula kwakhona, enokwenza ukuba isakhiwo sensimbi sincinci..

Spheroidizing Annealing.Isetyenziselwa ukunciphisa ubunzima obuphezulu bensimbi yesixhobo kunye nentsimbi yokuthwala emva kokubumba.I-workpiece ishushu kwi-20-40 ° C ngaphezu kweqondo lokushisa apho intsimbi iqala ukwenza i-austenite, kwaye ipholile ngokukhawuleza emva kokugcinwa kobushushu.Ngethuba lenkqubo yokupholisa, i-lamellar cementite kwi-pearlite iba yi-spherical, ngaloo ndlela inciphisa ubunzima.
