Ukubunjwa kwamakhemikhali kanye ne-Microstructure
Ukwakheka kwamakhemikhali kwemidiya ephezulu yokugaya i-chrome kuyisici esibalulekile esithinta kakhulu ukusebenza kwayo ezinhlelweni ezahlukahlukene zezimboni. Izingxenye eziyinhloko zale midiya yokugaya zifaka i-carbon, i-chromium, nezinye izakhi ze-alloying ezifana ne-manganese, i-molybdenum, ne-nickel. Phakathi kwalokhu, okuqukethwe kwe-chromium, ngokuvamile okusukela ku-10% kuya ku-30%, kubaluleke kakhulu njengoba kudlala indima ebalulekile ekuthuthukiseni ukwakheka kwama-carbides aqinile ngaphakathi kwempahla. Lokhu kwakheka kwe-carbide kubalulekile ekuthuthukiseni ukumelana nokugqoka kanye nokuqina, ngaleyo ndlela kuvumela imidiya yokugaya ukuthi ibekezelele izimo ezinzima ezihlangatshezwana nazo ngesikhathi sokusebenza kokugaya.
I-microstructure yemidiya yokugaya, ethonywa ngokuyinkimbinkimbi kokubili ukwakheka kwamakhemikhali kanye nenqubo yokwelapha ukushisa, idlala indima ebalulekile ekunqumeni izici zayo eziphelele nezici zokusebenza. I-microstructure elinganisene kahle ehlanganisa i-martensite, i-austenite egciniwe, ne-carbides ifiseleka kakhulu ukuze kuzuzwe ukusebenza okuphelele. Ukusatshalaliswa nokwakheka kwalezi zigaba kuthinta ngokuqondile izici ezibucayi njengokuqina, ukuqina, nokumelana nokugqokwa, okubalulekile ekugayeni okuphumelelayo.
Izinqubo zokwelashwa kokushisa, okuhlanganisa ukucisha kanye nokushisa, zisetshenziswa ngokuhlelekile ukuze kuzuzwe i-microstructure oyifunayo kanye nezakhiwo zemishini zemidiya yokugaya. Phakathi nenqubo yokucisha, izinga lokupholisa lilawulwa ngokucophelela, njengoba lithinta kakhulu ukwakheka kwe-martensite nokugcinwa kwe-austenite. Ukulandela ukucisha, izinga lokushisa lokushisa libuye likhethwe ngokucophelela ukuze kuncishiswe ukucindezeleka kwangaphakathi futhi kucwengisiswe i-microstructure ngokuqhubekayo. Ukwelashwa okufanelekile kokushisa kuqinisekisa i-microstructure ene-homogeneous enama-carbides asatshalaliswa ngokulinganayo, okunikela ekuqiniseni ukumelana nokugqokwa nokusebenza kukonke. Ngokulungiselela kokubili ukwakheka kwamakhemikhali kanye nezinqubo zokwelashwa kokushisa, abakhiqizi bangakhiqiza imidiya yokugaya i-chrome ephezulu ezihlangabezana nezidingo ezidingekayo zezinhlelo zokusebenza ezihlukene zezimboni, ekugcineni okuholela ekusebenzeni okuthuthukisiwe kanye nokuphumelela kwezindleko ekusebenzeni.
Izakhiwo Zomzimba kanye Nenqubo Yokukhiqiza
Izici ezibonakalayo zemidiya yokugaya i-chrome ephezulu, okuhlanganisa usayizi, umumo, nezici ezingaphezulu, zinomthelela omkhulu ekusebenzeni kwayo kokugaya. Ubukhulu bemidiya yokugaya bukhethwa ngokusekelwe kuhlelo lokusebenza oluthile kanye nobukhulu bezinhlayiya obufunayo bezinto zomhlabathi. Imidiya emincane ivamise ukusebenza kahle kakhulu ekugayeni kahle, kuyilapho imidiya emikhulu ifanele imisebenzi yokugaya amaholoholo.
Ukuma kwemidiya yokugaya nakho kunomthelela ekusebenzeni kwayo. Amabhola ayindilinga ayifomu elivame kakhulu, enikeza ukugeleza okuhle nokugqokwa komfaniswano. Kodwa-ke, ama-cylpebs (ama-cylindrical pellets) athola ukuduma ezinhlelweni ezithile ngenxa yokwanda kwendawo yawo kanye namandla okwenza ngcono ukusebenza kahle kokugaya.
Inqubo yokukhiqiza ye imidiya yokugaya i-chrome ephezulu ibalulekile ekunqumeni izinga nokusebenza kwayo. I-Casting iyindlela eyinhloko esetshenziswayo, ngamasu afana nokubunjwa kwesihlabathi, ukubunjwa kwensimbi, kanye ne-centrifugal casting. Inqubo yokulingisa ithinta isakhiwo sangaphakathi, i-porosity, kanye nekhwalithi ephezulu yemidiya. Amasu okulingisa athuthukile nezinyathelo zokulawula ikhwalithi zibalulekile ukuze kukhiqizwe imidiya yokugaya esebenza kahle enezici ezingaguquki.
Izindlela zokwelapha ezingaphezulu, ezifana nokuchama noma ukuqinisa indawo, zingasetshenziswa ukuze kuthuthukiswe ukumelana nokuguga kanye nokuqina komthelela wemidiya yokugaya. Lezi zindlela zokwelapha ziguqula izici ezingaphezulu, zenze isendlalelo sokucindezeleka esicindezelayo esithuthukisa ukuqina kwemidiya kanye nokumelana nokusakazeka kokuqhekeka.
Izimo zokusebenza namapharamitha okugaya
Ukusebenza kwe- imidiya yokugaya i-chrome ephezulu kuthonywa kakhulu izimo zokusebenza namapharamitha wokugaya lapho asetshenziswa khona. Izinto ezifana nesivinini sokugaya, ukushaja kwebhola, nokuminyana kwe-slurry kunomthelela omkhulu ekusebenzeni kahle kokugaya kanye nezinga lokuguga kwemidiya.
Isivinini se-Mill sithinta ukunyakaza kwemidiya yokugaya kanye nokudluliswa kwamandla ezintweni eziphansi. Ukusebenza ngesivinini esifanelekile kuqinisekisa ukugeleza okusebenzayo kanye ne-cataracting kwabezindaba, kukhulisa ukusebenza kahle kokugaya kuyilapho kunciphisa ukuguga. Isivinini esibucayi, okuyijubane lethiyori lapho imidiya yokugaya izoba yi-centrifuge, iyipharamitha ebalulekile ekunqumeni isivinini sokusebenza esilungile.
Ishaja yebhola, noma ivolumu yemidiya yokugaya emshinini, ithinta amandla okugaya nokusebenza kahle. Ukushaja kwebhola okuphelele kuqinisekisa ukuthintana okwanele kwemidiya-kuya-kwabezindaba kanye nokuxhumana kwemidiya kuya kokubalulekile kuyilapho kuvumela isikhala esanele sokunyakaza kwezinto ezibonakalayo. Ukushaja ngokweqile noma ukushaja okuncane kwesigayo kungaholela ekwehliseni ukusebenza kahle kokugaya kanye nokwenyuka kokuguga kwemidiya.
Ukuminyana kwe-slurry, okubhekisela esilinganisweni sokuqinile namanzi esigayweni, kuthonya izinsimbi zokugaya nokuguga kwemidiya. Ukuminyana okuphezulu kwe-slurry ngokuvamile kuphumela ekwenyukeni kokusebenza kahle kokugaya kodwa kungase futhi kuholele emazingeni aphezulu okuguga kwemidiya. Ukulinganisa lezi zici kubalulekile ekuthuthukiseni inqubo yokugaya kanye nokwandisa impilo yemidiya yokugaya.
Izinto ezigaywayo nazo zidlala indima ekusebenzeni kwemidiya yokugaya i-chrome ephezulu. Izinto eziqinile neziqhumayo zingabangela ukuguga okusheshayo, kuyilapho izinto ezithambile zingase zibangele amazinga okugaya kancane. Ukuqonda izici zezinto eziphakelayo kanye nokulungisa amapharamitha okugaya ngokufanele kubalulekile ukuze kuzuzwe ukusebenza kahle.
Sengiphetha, ukusebenza kwemidiya ephezulu yokugaya i-chrome kuthonywa ukusebenzisana okuyinkimbinkimbi kwezinto, okuhlanganisa ukwakheka kwamakhemikhali, i-microstructure, izakhiwo ezibonakalayo, izinqubo zokukhiqiza, nezimo zokusebenza. Ngokucubungula ngokucophelela nokuthuthukisa lezi zici, izimboni zingathuthukisa ukusebenza kahle kwazo kokugaya, zehlise izinga lokuguga, futhi zithuthukise ukukhiqiza kukonke. Njengoba ubuchwepheshe nocwaningo kulo mkhakha luqhubeka nokuthuthuka, singalindela ukuthuthuka okwengeziwe ekusebenzeni nokuphila isikhathi eside kwemidiya ephezulu yokugaya i-chrome.
Ukuze uthole ulwazi olwengeziwe mayelana nekhwalithi ephezulu imidiya yokugaya i-chrome ephezulu kanye nezeluleko zochwepheshe zokuthuthukisa izinqubo zakho zokugaya, sicela usithinte ku sales@da-yang.com futhi sunny@da-yang.com. Ithimba lethu lochwepheshe e-NINGHU lilungele ukukusiza ekutholeni isisombululo esiphelele semidiya yokugaya ngezidingo zakho ezithile.
