Xa ukhetha uhlobo lwentsimbi engagqwaliyo (SS) kwisicelo sakho okanye kwiprototype, kubalulekile ukuqwalasela ukuba ngaba kufuneka iimpawu zemagnethi. Ukuze wenze isigqibo esinolwazi, kubalulekile ukuqonda izinto ezigqiba ukuba uhlobo lwentsimbi engagqwaliyo lunemagnethi okanye akunjalo.
Iintsimbi ezingagqwaliyo zii-alloys ezisekelwe kwisinyithi ezidumileyo ngokumelana kwazo kakuhle nokugqwala. Kukho iintlobo ngeentlobo zeentsimbi ezingagqwaliyo, apho iindidi eziphambili ziyi-austenitic (umz., 304H20RW, 304F10250X010SL) kunye ne-ferritic (esetyenziswa rhoqo kwizicelo zeemoto, izixhobo zasekhitshini, nakwizixhobo zoshishino). Ezi ndidi zinemilo eyahlukeneyo yeekhemikhali, nto leyo ekhokelela kwiindlela zazo ezahlukeneyo zemagnethi. Iintsimbi ezingagqwaliyo ze-Ferritic zihlala zineemagnethi, ngelixa iintsimbi ezingagqwaliyo ze-austenitic zingenjalo. Imagnethi yentsimbi engagqwaliyo ye-ferritic ivela kwizinto ezimbini eziphambili: umxholo wayo ophezulu wesinyithi kunye nolwakhiwo lwayo olusisiseko.
Utshintsho ukusuka kwiZigaba ezingezizo zeMagnetic ukuya kwiZigaba zeMagnetic kwiNsimbi engagqwaliyo
Zombini304kwaye iintsimbi ezingenanto ezingama-316 ziwela phantsi kodidi lwe-austenitic, oko kuthetha ukuba xa zipholile, intsimbi igcina imo yayo ye-austenite (i-gamma iron), isigaba esingengo-magnetic. Izigaba ezahlukeneyo zentsimbi eqinileyo zihambelana nezakhiwo zekristale ezahlukeneyo. Kwezinye ii-alloys zentsimbi, esi sigaba sentsimbi esinobushushu obuphezulu siguquka sibe sisigaba se-magnetic ngexesha lokuphola. Nangona kunjalo, ubukho be-nickel kwii-alloys zentsimbi engaqhotyoshelwanga kuthintela olu tshintsho lwesigaba njengoko i-alloy iphola ukuya kubushushu begumbi. Ngenxa yoko, intsimbi engaqhotyoshelwanga ibonisa ukuthambekela okuphezulu kancinci kwe-magnetic kunezixhobo ezingengo-magnetic ngokupheleleyo, nangona isahleli ingaphantsi koko kudla ngokuthathwa njenge-magnetic.
Kubalulekile ukuqaphela ukuba akufuneki ulindele ukuba ulinganise ukuba amandla ombane aphantsi kangaka kwiqhekeza ngalinye le-304 okanye i-316 stainless steel odibana nayo. Nayiphi na inkqubo ekwaziyo ukutshintsha isakhiwo sekristale se-stainless steel inokubangela ukuba i-austenite iguqukele kwi-ferromagnetic martensite okanye kwiifom ze-ferrite zesinyithi. Ezi nkqubo ziquka ukusebenza ngokubandayo kunye nokuwelda. Ukongeza, i-austenite inokuguquka ngokuzenzekelayo ibe yi-martensite kumaqondo obushushu aphantsi. Ukongeza ubunzima, iimpawu zemagnethi zezi alloys zichatshazelwa kukwakheka kwazo. Nokuba ngaphakathi koluhlu oluvumelekileyo lokwahluka komxholo we-nickel kunye ne-chromium, umahluko obonakalayo kwiimpawu zemagnethi unokubonwa kwi-alloy ethile.
Izinto Ezibalulekileyo Omele Uziqwalasele Xa Ususa Iinxalenye Zentsimbi Engagqwaliyo
Zombini i-304 kunyeIntsimbi engagqwaliyo engama-316zibonisa iimpawu ze-paramagnetic. Ngenxa yoko, amasuntswana amancinci, afana neesphere ezinobubanzi obuqala kwi-0.1 ukuya kwi-3mm, anokutsalwa kwiindawo zokwahlulahlula imagnethi ezinamandla ezibekwe ngobuchule ngaphakathi komjelo wemveliso. Ngokuxhomekeke kubunzima bazo, kwaye okubaluleke ngakumbi, ubunzima bazo xa kuthelekiswa namandla okutsala kwemagnethi, la masuntswana amancinci aya kunamathela kwiimagnethi ngexesha lenkqubo yemveliso.
Emva koko, la masuntswana anokususwa ngempumelelo ngexesha lemisebenzi yokucoca imagnethi rhoqo. Ngokusekelwe kwimbono yethu esebenzayo, sifumanise ukuba amasuntswana entsimbi engagqwaliyo angama-304 anokuthi agcinwe kumanzi xa kuthelekiswa namasuntswana entsimbi engagqwaliyo angama-316. Oku kubangelwa ikakhulu bubukho bemagnethi obuphezulu kancinci bentsimbi engagqwaliyo engama-304, nto leyo eyenza ukuba iphendule ngakumbi kwiindlela zokwahlulahlula imagnethi.
