Dhowaan, heerka qaran GB/T20878-2024 "Fasalada birta aan daxalka lahayn iyo Waxyaabaha Kiimikada", oo uu tafatiray Machadka Cilmi-baarista Heerarka Macluumaadka Warshadaha Metallurgical oo ay ka qaybqaateen Fujian Qingtuo Special Steel Technology Research Co., Ltd. iyo cutubyo kale, ayaa la sii daayay waana la sii dayn doonaa waxaa la dhaqan gelinayaa Febraayo 1, 2025. Ka dib ku dhawaad lix sano oo dadaal ah oo aan kala go 'lahayn, Kooxda Qingtuo waxay si madaxbanaan u soo saartay nitrogen-ka kooban aadka loo xoojiyay austenitic steel QN taxane ah, oo ay ku jiraan S35250 (QN1701), S25230 (QN1801), S35657 (QN1803), S35656 (QN1538) heerarka iska caabinta daxalka sida QF1804), S35706 (QN2008), S35886 (QN1906) iyo S35887 (QN2109) ayaa lagu soo daray heerkan, kobcinta qaab dhismeedka kala duwan ee birta ah iyo bixinta xoog sare, khafiif ah, iyo iska caabin sare daxalka ee beerta qaab-dhismeedka rarka-xambaarsan. Qorshaha xaqiijinta ee noocyada kala duwan ee birta ah ee leh badbaadada sare iyo waxtarka qiimaha leh.
S35656 (QN1804) waxay ku tiirsan tahay caabbinta daxalka aadka u fiican, alxanka iyo guryaha heerkulka hooseeya ee lagu daro GB/T150.2-2024 "Qaybta Cadaadiska Qaybta 2: Qalabka" iyo GB/T713.7-2023 "Steel Plate and Steel" Qalabka Cadaadiska" Qeybta 7: Birta Aan Laheyn iyo Heat-Resistant Steel” iyo labada heer qaran ee kale ee la xidhiidha maraakiibta cadaadiska. Dhawrkii sano ee la soo dhaafay, birta taxan ee QN waxay samaysatay silsilad warshadeed oo xasiloon waxaana lagu dabaqay qaybo badan oo ka mid ah suuqa qaab dhismeedka xamuulka qaada sida injineernimada tunnel-ka tareenka xawaaraha sare leh, dhismayaal hore loo hagaajiyay, injineernimada tareenka dhulka hoostiisa mara, tamarta, injineernimada badda iyo weelasha cadaadiska.
Electropolishingwaa habka dhamaystirka kiimikaad kiimikaad ah oo ka saara lakabka khafiifka ah ee walxaha qayb ka mid ah birta, sida caadiga ah birta aan lahayn ama alwaaxyada la midka ah. Nidaamku wuxuu ka tagayaa dhalaal, siman, dhammaystir dusha aadka u nadiifsan.
Sidoo kale loo yaqaanpolishing koronto kiimikaad, polishing anodicamapolishing electrolytic, electropolishing waxay si gaar ah faa'iido u leedahay sifaynta iyo nadiifinta qaybaha jilicsan ama leh joomatari adag. Electropolishing waxay hagaajinaysaa dhamaystirka dusha sare iyadoo hoos u dhigaysa qallafsanaanta dusha sare ilaa 50%.
Electropolishing waxaa loo malayn karaa sidakoronto ku celis ah. Halkii lagu dari lahaa dahaarka khafiifka ah ee ion birta si togan loo dallaco, elektropolishing waxay isticmaashaa korantada si ay u milmaan lakabka khafiifka ah ee ion birta oo loo beddelo dareeraha korantada.
Electropolishing ee birta aan lahayn ayaa ah isticmaalka ugu badan ee isticmaalka korantada. Birta birta ah ee korontadu leedahay waxay leedahay dhammays siman, dhaldhalaal ah, nadiif ah oo iska caabiya daxalka. In kasta oo ku dhawaad bir kasta ay shaqayn doonto, biraha ugu badan ee korantada lagu shubo waa 300- iyo 400-taxane ah oo ah bir aan lahayn.
Dhammaystirka korantada ayaa leh heerar kala duwan oo loo isticmaalo codsiyada kala duwan. Codsiyadani waxay u baahan yihiin dhammaystir dhexdhexaad ah. Electropolishing waa geeddi-socod loo marayo qallafsanaanta buuxda ee tuubada birta ah ee korantada ee la dhimay. Tani waxay ka dhigaysaa tuubooyinka si sax ah cabbirkooda iyo EP Pipe waxaa lagu rakibi karaa si sax ah hababka xasaasiga ah sida kuwacodsiyada warshadaha dawooyinka.
Waxaan leenahay qalab polishing noo gaar ah oo soo saara tuubooyinka polishing electrolytic kuwaas oo buuxiya shuruudaha beeraha kala duwan iyadoo ay hagidda kooxda farsamada Korean.
Tuubadayada EP ee ISO14644-1 Fasalka 5 xaaladaha qolka nadiifka ah, tuubo kasta ayaa lagu nadiifiyaaNadiifinta ultra sare (UHP)nitrogen ka dibna daboolan oo labajibbaaran. Shahaado u qalma heerka wax soo saarka tubbada, ka kooban kiimikaad, baafinta walxaha, iyo qallafsanaanta dusha sare ee ugu badan ayaa la bixiyaa dhammaan walxaha.
