Ungabhekana Kanjani Ne-Decarburization Ekwelashweni Kokushisa?

I-Decarburization yinto evamile futhi eyinkinga eyenzeka ngesikhathi sokwelashwa kokushisa kwensimbi namanye ama-alloys aqukethe i-carbon. Kubhekiselwa ekulahlekeni kwekhabhoni kusuka kungqimba olungaphezulu lwento lapho kuvezwa amazinga okushisa aphezulu ezindaweni ezikhuthaza ukugcotshwa kwe-oxidation. I-Carbon iyisici esibalulekile ensimbi, enomthelela emandleni ayo, ubulukhuni, nokumelana nokugqoka. Ngakho-ke, ukususwa kwe-carburization kungaholela ekuncishisweni kwezakhiwo zemishini, ukuwohloka kwendawo, kanye nezinkinga zekhwalithi yomkhiqizo jikelele. Ukuze kubhekwane ngokuphumelelayo ne-decarburization ekwelapheni ukushisa, uhla lwezindlela namasu okuvimbela angasetshenziswa.

1. Ukulawula Umkhathi

Enye yezindlela ezisebenza kahle kakhulu zokunciphisa ukukhishwa kwe-carburization ukulawula umoya wesithando somlilo ngesikhathi senqubo yokwelapha ukushisa. Ukususwa kwe-carburization kwenzeka lapho ikhabhoni esensimbini ihlangana nomoya-mpilo noma amanye amagesi afana ne-carbon dioxide, yakhe i-carbon monoxide noma i-carbon dioxide ephuma phezulu. Ukuvimbela lokhu, umoya ongasebenzi noma onciphisayo kufanele usetshenziswe. Amagesi avamile ahlanganisa i-nitrogen, i-argon, noma i-hydrogen, eyenza indawo engenawo umoya-mpilo, enciphisa ingozi yokulahlekelwa yikhabhoni.

Ezinye izinqubo zokwelashwa kokushisa zisebenzisa isithando somlilo ukuze kuqedwe ngokuphelele ukuba khona kwamagesi angasabela ngendawo yensimbi. Le ndlela iphumelela ikakhulukazi ezingxenyeni zenani eliphezulu lapho ngisho nokususa i-carburization encane kungamukeleki. Okunye, i-carburizing atmosphere, lapho kusetshenziswa khona amagesi anothe ngekhabhoni, angasiza ekugcineni noma akhuphule ngisho namazinga ekhabhoni engaphezulu, alwe nokuwohloka okungaba khona.

2. Ukusetshenziswa Kwezingubo Zokuzivikela

Ukusebenzisa okokuvikela okuyisivikelo kungenye indlela yokuvikela i-material ekususweni kwe-carburization. Izembatho ezinjengama-ceramic paste, i-copper plating, noma amapende akhethekile angasebenza njengezithiyo ezibonakalayo, avimbele ikhabhoni ukuthi ingaphumi phezulu. Lezi zimbobo ziwusizo ikakhulukazi ezingxenyeni ezidlula imijikelezo yokwelashwa okude noma ezingxenyeni ezivezwe endaweni ene-oxidative kakhulu.

3. Ukuthuthukisa Amapharamitha Wokwelapha Ukushisa

I-Decarburization incike kumazinga okushisa, okusho ukuthi uma izinga lokushisa liphezulu, maningi amathuba okuba ikhabhoni iphume endaweni yensimbi. Ngokukhetha ngokucophelela amazinga okushisa nezikhathi zokwelashwa kokushisa, ingcuphe yokukhishwa kwe-decarburization ingancishiswa. Ukwehlisa izinga lokushisa lenqubo noma ukunciphisa isikhathi sokuchayeka emazingeni okushisa aphezulu kunganciphisa kakhulu izinga lokulahleka kwekhabhoni. Kwezinye izimo, ukupholisa izikhawu phakathi kwemijikelezo emide nakho kungaba yinzuzo, njengoba kunciphisa isikhathi sonke lapho okokusebenza kuvezwa khona ezimeni ze-decarburizing.

4. Izinqubo Ngemva Kokwelashwa

Uma ukukhishwa kwe-decarburization kwenzeka naphezu kwezinyathelo zokuvimbela, izinqubo zangemuva kokwelashwa ezinjengokugaya indawo noma umshini zingase zisetshenziswe ukuze kukhishwe ungqimba owenziwe nge-decarburized. Lokhu kubaluleke kakhulu ekusebenzeni lapho izakhiwo ezingaphezulu njengokuqina nokumelana nokugqokwa kubalulekile. Kwezinye izimo, inqubo yesibili ye-carburizing ingasetshenziswa ukubuyisela ikhabhoni elahlekile kungqimba olungaphezulu, ngaleyo ndlela kubuyiselwe izakhiwo ezifiselekayo zemishini.

I-Decarburization ekwelapheni ukushisa yindaba ebucayi engaba nomthelela omkhulu ekusebenzeni kanye nekhwalithi yezingxenye zensimbi. Ngokulawula umkhathi wesithando somlilo, usebenzisa okokuvikelayo, ukwenza ngcono imingcele yenqubo, nokusebenzisa izindlela zokulungisa ngemva kokwelashwa, imiphumela emibi yokukhishwa kwecarburization ingancishiswa ngempumelelo. Lawa maqhinga aqinisekisa ukuthi izinto ezilashwayo zigcina amandla azo ahlosiwe, ubulukhuni, nokuqina, ekugcineni athuthukise ikhwalithi iyonke yomkhiqizo wokugcina.
