Vuba aha, hasohotse itegeko rigenga imiterere y’icyuma gikozwe mu buryo bwa "Stainless Steel Grades and Chemical Compositions" rya GB/T20878-2024 ku rwego rw’igihugu, ryatunganyijwe n’ikigo gishinzwe ubushakashatsi ku bijyanye n’amakuru mu nganda za metallurgical, rikaba ryaritabiriwe na Fujian Qingtuo Special Steel Technology Research Co., Ltd. n’andi mashami, kandi rizashyirwa mu bikorwa ku ya 1 Gashyantare 2025. Nyuma y'imyaka hafi itandatu y'ingamba zidashira, Qingtuo Group yateguye ku giti cyayo uruhererekane rwa QN rw'icyuma kitagira umugese cya austenitic gifite azote ikomeye cyane, harimo S35250 (QN1701), S25230 (QN1801), S35657 (QN1803), S35656 (QN1804), S35388 (Ibicuruzwa bifite urwego rutandukanye rwo kurwanya ingese nka QF1804), S35706 (QN2008), S35886 (QN1906) na S35887 (QN2109) byashyizwe muri ubu buryo, byongera imiterere y'ubwoko bw'icyuma kitagira umugese kandi bitanga imbaraga nyinshi, zoroshye, kandi zirwanya ingese nyinshi ku rwego rw'inyubako zitwara imizigo. Gahunda yo gushyira mu bikorwa ubwoko bw'icyuma kitagira umugese bufite umutekano mwinshi kandi buhendutse.
S35656 (QN1804) yishingikiriza ku buryo bwayo bwiza bwo kurwanya ingese, ubushuhe bwo gusudira hamwe n’ubushobozi bwayo bwo gukoresha ubushyuhe buke bushyirwa muri GB/T150.2-2024 “Ibyuma bitanga umuvuduko Igice cya 2: Ibikoresho” na GB/T713.7-2023 “Icyuma n’icyuma byo gukoresha ibikoresho bitanga umuvuduko” hamwe n’igice cya 7: Ibyuma bitanga umuvuduko n’icyuma kidashyuha” hamwe n’ibindi bipimo bibiri by’igihugu bifitanye isano n’ibyuma bitanga umuvuduko. Mu myaka mike ishize, icyuma gitanga umuvuduko cya QN cyakoze urunigi ruhamye rw’inganda kandi cyakoreshejwe mu byiciro byinshi mu masoko atandukanye yo gutwara imizigo nko mu buhanga bwa gari ya moshi yihuta, inyubako zakozwe mbere, ubwubatsi bwa gari ya moshi zo munsi y’ubutaka, ingufu, ubwubatsi bw’inyanja n’ibyuma bitanga umuvuduko.
Gutunganya amashanyarazini inzira yo kurangiza hakoreshejwe amashanyarazi ikuraho urwego rworoshye rw'ibikoresho mu gice cy'icyuma, akenshi icyuma kitagira umugese cyangwa ibindi bisa nacyo. Iyi nzira isiga ubuso bubengerana, bworoshye kandi busukuye cyane.
Bizwi kandi nkagushushanya hakoreshejwe amashanyarazi, gushushanya hakoreshejwe anodikecyangwagushushanya hakoreshejwe amashanyarazi, electropolishing ni ingirakamaro cyane mu gusiga no gukuraho ibice byoroshye cyangwa bifite imiterere y’ubuso igoye. Electropolishing irushaho kunoza imiterere y’ubuso binyuze mu kugabanya ubukana bw’ubuso kugeza kuri 50%.
Gutunganya hakoreshejwe amashanyarazi bishobora gufatwa nk'ikintuelectroplating isubira inyumaAho kongeramo irangi ryoroheje rya iyoni z'icyuma zifite amashanyarazi meza, electropolishing ikoresha amashanyarazi kugira ngo ishongeshe urwego rwo hasi rwa iyoni z'icyuma mu gisubizo cya electrolyte.
Gutunganya ibyuma bitagira umugozi ni byo bikunze gukoreshwa cyane mu gutunganya ibyuma bitagira umugozi. Ibyuma bitagira umugozi bifite irangi ryiza, rirabagirana kandi risukuye cyane rirwanya ingese. Nubwo hafi ya byose ibyuma bizakora, ibyuma bikunze gukoreshwa mu gutunganya ibyuma bitagira umugozi ni ibyuma bitagira umugozi 300 na 400.
Gusoza icyuma gikozwe mu buryo bwa electroplating bifite amahame atandukanye yo gukoresha mu buryo butandukanye. Izi porogaramu zisaba urwego rwo hagati rwo kurangiza. Gusoza icyuma gikozwe mu buryo bwa electropolishing ni inzira inyuramo aho umuyoboro w'icyuma gikozwe mu buryo bwa electropolished ugabanuka. Ibi bituma imiyoboro iba myiza mu bipimo kandi umuyoboro wa EP ushobora gushyirwaho neza mu buryo bufatika muri sisitemu zoroshye nkaikoreshwa mu nganda zikora imiti.
Dufite ibikoresho byacu byo gusiga irangi kandi dukora imiyoboro yo gusiga irangi ikoresheje amashanyarazi ijyanye n'ibikenewe mu nzego zitandukanye tuyobowe n'itsinda ry'abahanga bo muri Koreya.
Umuyoboro wacu wa EP uri mu cyumba gisukuye cya ISO14644-1 cyo mu cyiciro cya 5, buri muyoboro usukurwa hakoreshejweubuziranenge buhanitse cyane (UHP)azote hanyuma igapfundikirwa hanyuma igashyirwa mu mifuka ibiri. Icyemezo cyerekana ko imiyoboro y’amazi ikora neza, imiterere yayo, uburyo ikurikirana ibikoresho, ndetse n’ubuso bwayo ntarengwa ni byo bitangwa ku bikoresho byose.
