Xa ukhetha ibakala lensimbi engenasici (SS) kwisicelo sakho okanye iprototype, kubalulekile ukuqwalasela ukuba ziyafuneka iipropathi zemagneti.Ukwenza isigqibo esinolwazi, kubalulekile ukuqonda izinto eziqinisekisa ukuba ibakala lensimbi engenastainless linomagnetic okanye hayi.
Iintsimbi ezingenastainless zialloyi ezisekwe kwintsimbi ezidume ngokuxhathisa kwazo ngokugqwesileyo ekudlekeni.Kukho iindidi ngeendidi zeentsimbi ezingenasici, kunye neendidi eziphambili ziyi-austenitic (umz., 304H20RW, 304F10250X010SL) kunye ne-ferritic (ehlala isetyenziswa kwizicelo zeemoto, ikhitshi, kunye nezixhobo zoshishino).Ezi ndidi zinokwakheka kweekhemikhali ezahlukeneyo, ezikhokelela kumohluko wokuziphatha kwamagnethi.Iintsimbi ezingenasici zeFerritic zithande ukuba ngumagnetic, kanti iintsimbi ezingenasici ze-austenitic azikho.I-magnetism yensimbi engenasici ye-ferritic ivela kwizinto ezimbini eziphambili: umxholo wayo wentsimbi ephezulu kunye nokuhlelwa kwayo okusisiseko.
Utshintsho ukusuka kwiZigaba ezingezizo iMagnetic ukuya kwiMagnetic kwiSimbi eStainless
Zombini304kunye neentsimbi ze-316 ezingenasici ziwela phantsi kodidi lwe-austenitic, oku kuthetha ukuba xa zipholile, intsimbi igcina i-austenite (i-gamma iron) ifom, isigaba esingenamagnetic.Izigaba ezahlukeneyo zentsimbi eqinileyo zihambelana nezakhiwo zekristale.Kwezinye ii-alloys zensimbi, esi sigaba sentsimbi esinobushushu obuphezulu sitshintsha sibe yimagnethi ngexesha lokupholisa.Nangona kunjalo, ubukho be-nickel kwi-alloys yensimbi engenasici kuthintela le nguqu yesigaba njengoko i-alloy iphola kwiqondo lokushisa.Ngenxa yoko, intsimbi engatyiwayo ibonisa ukuchaphazeleka kwemagnethi ephezulu kancinci kunezixhobo ezingezizo ezemagneti, nangona ihleli ingaphantsi kwento ethathwa njengemagnethi.
Kubalulekile ukuqaphela ukuba akufuneki ulindele ukulinganisa ukuchaphazeleka kwemagnethi esezantsi kangako kwisiqwenga ngasinye se304 okanye 316 yentsimbi engenasici odibana nayo.Nayiphi na inkqubo ekwaziyo ukuguqula ubume bekristale yentsimbi engenasici inokubangela ukuba i-austenite iguqukele kwi-ferromagnetic martensite okanye iifom ze-ferrite zentsimbi.Iinkqubo ezinjalo ziquka ukusebenza okubandayo kunye ne-welding.Ukongeza, i-austenite inokutshintsha ngokuzenzekelayo ibe yi-martensite kumaqondo obushushu asezantsi.Ukongeza ubunzima, iipropati zamagnetic zala ma-alloys zithonywa ngokubunjwa kwazo.Nangaphakathi kweendidi ezivumelekileyo zokwahluka kwi-nickel kunye nomxholo wechromium, umahluko obonakalayo kwiipropathi zamagnetic unokuqwalaselwa kwi-alloy ethile.
Iingqwalaselo eziSebenzayo zokuSusa amasuntswana eStainless Steel
Zombini 304 kunye316 intsimbi engatyiwayobonisa iimpawu zeparamagnetic.Ngenxa yoko, amasuntswana amancinane, anje ngeengqukuva ezinedayamitha ukusuka malunga ne-0.1 ukuya kwi-3mm, zinokutsalwa ngokubhekiselele kwizahluli ezinamandla zemagnethi ezibekwe ngobuchule ngaphakathi kumjelo wemveliso.Ngokuxhomekeke kubunzima babo kwaye, okona kubaluleke kakhulu, ubunzima babo ngokubhekiselele kumandla okukhanga kwamagnetic, la masuntswana amancinci aya kubambelela kumagnethi ngexesha lenkqubo yokuvelisa.
Emva koko, la masuntswana anokususwa ngempumelelo ngexesha lesiqhelo lokucocwa kwemagnethi.Ngokusekwe kuqwalaselo lwethu olusebenzayo, sifumanise ukuba amasuntswana angama-304 entsimbi engenastainless kunokwenzeka ukuba agcinwe xa ebaleka xa kuthelekiswa namasuntswana angama-316 entsimbi engatyiwayo.Oku kubalelwa ikakhulu kubume bemagnethi obuphezulu kancinane be-304 yentsimbi engatyiwayo, nto leyo eyenza ukuba iphendule ngakumbi kubuchule bokwahlula ngemagnethi.
