Zinthu za QN zotsatizana ndi chitsulo chosapanga dzimbiri cha austenitic zomwe zili ndi nayitrogeni yolimba kwambiri zikuphatikizidwa mu GB/T20878-2024 ya dziko lonse ndipo zatulutsidwa.

Posachedwapa, muyezo wa dziko lonse wa GB/T20878-2024 “Stainless Steel Grades and Chemical Compositions”, wokonzedwa ndi Metallurgical Industry Information Standards Research Institute ndipo unachitidwa ndi Fujian Qingtuo Special Steel Technology Research Co., Ltd. ndi mayunitsi ena, unatulutsidwa ndipo udzayamba kugwira ntchito pa February 1, 2025. Pambuyo pa zaka pafupifupi zisanu ndi chimodzi zoyesayesa mosalekeza, Qingtuo Group idapanga payokha mndandanda wa QN wa chitsulo chosapanga dzimbiri chopangidwa ndi nayitrogeni, kuphatikiza S35250 (QN1701), S25230 (QN1801), S35657 (QN1803), S35656 (QN1804), S35388 (Zogulitsa zomwe zimakhala ndi milingo yosiyanasiyana yolimbana ndi dzimbiri monga QF1804), S35706 (QN2008), S35886 (QN1906) ndi S35887 (QN2109) zaphatikizidwa mu muyezo uwu, zomwe zawonjezera kapangidwe ka chitsulo chosapanga dzimbiri ndikupereka mphamvu yayikulu, yopepuka, komanso yolimbana ndi dzimbiri m'munda wa nyumba zonyamula katundu. Dongosolo lokwaniritsa mitundu ya chitsulo chosapanga dzimbiri yokhala ndi chitetezo chapamwamba komanso yotsika mtengo. 

S35656 (QN1804) imadalira kukana dzimbiri, kusinthasintha, komanso mphamvu zake zotenthetsera kutentha zomwe zikuphatikizidwa mu GB/T150.2-2024 "Ziwiya Zopanikizika Gawo 2: Zipangizo" ndi GB/T713.7-2023 "Mbale Yachitsulo ndi Chitsulo cha Zipangizo Zopanikizika" Ndi Gawo 7: Chitsulo Chosapanga Dzimbiri ndi Chitsulo Chosatentha" ndi miyezo ina iwiri yadziko lonse yokhudzana ndi zombo zopanikizika. M'zaka zingapo zapitazi, zitsulo zosapanga dzimbiri za QN zapanga unyolo wokhazikika wa mafakitale ndipo zakhala zikugwiritsidwa ntchito m'magulu osiyanasiyana pamsika wonyamula katundu monga uinjiniya wa njanji yachangu, nyumba zokonzedwa kale, uinjiniya wa sitima yapansi panthaka, mphamvu, uinjiniya wa nyanja ndi zombo zopanikizika.

Kupukuta kwamagetsiNdi njira yomaliza yamagetsi yomwe imachotsa zinthu zochepa kuchokera ku chitsulo, nthawi zambiri chitsulo chosapanga dzimbiri kapena zinthu zina zofanana. Njirayi imasiya mawonekedwe owala, osalala, komanso oyera kwambiri.

Amadziwikanso kutikupukuta kwamagetsi, kupukuta kwa anodickapenakupukuta kwamagetsiKupukuta ndi magetsi kumathandiza kwambiri popukuta ndi kuchotsa zinthu zomwe zili zofooka kapena zokhala ndi mawonekedwe ovuta. Kupukuta ndi magetsi kumathandizira kuti pamwamba pakhale pomaliza pochepetsa kuuma kwa pamwamba ndi 50%.

Kupukuta kwamagetsi kungaganizidwe ngatielectroplating yobwerera m'mbuyoM'malo mowonjezera utoto woonda wa ma ayoni achitsulo okhala ndi positive-charged, electropolishing imagwiritsa ntchito magetsi kuti isungunule wosanjikiza woonda wa ma ayoni achitsulo kukhala yankho la electrolyte.

Kupukuta chitsulo chosapanga dzimbiri pogwiritsa ntchito magetsi ndiye njira yodziwika kwambiri yopukuta chitsulo. Chitsulo chosapanga dzimbiri chopukutidwa ndi magetsi chili ndi mawonekedwe osalala, owala, komanso oyera kwambiri omwe amalimbana ndi dzimbiri. Ngakhale kuti pafupifupi chitsulo chilichonse chimagwira ntchito, zitsulo zomwe zimagwiritsidwa ntchito kwambiri ndi magetsi ndi zitsulo zosapanga dzimbiri za 300- ndi 400-series.

Kumaliza kwa electroplating kuli ndi miyezo yosiyanasiyana yogwiritsira ntchito m'mapulogalamu osiyanasiyana. Mapulogalamuwa amafuna kumaliza kwapakati. Kupukuta kwa electro ndi njira yomwe imachepetsa kuuma kwa chitoliro chachitsulo chosapanga dzimbiri chopukutidwa ndi Electropolished. Izi zimapangitsa kuti mapaipi akhale olondola kwambiri ndipo chitoliro cha EP chikhoza kuyikidwa molondola m'makina osavuta mongantchito zamafakitale opanga mankhwala.

Tili ndi zida zathu zopukutira ndipo timapanga machubu opukutira amagetsi omwe amakwaniritsa zofunikira m'magawo osiyanasiyana motsogozedwa ndi gulu laukadaulo la ku Korea.

Chubu chathu cha EP chili ndi ISO14644-1 Class 5 yoyera m'chipinda, chubu chilichonse chimatsukidwa ndikuyera kwambiri (UHP)nayitrogeni kenako nkuphimba ndi kuyika matumba awiri. Chitsimikizo chotsimikizira miyezo yopangira chubu, kapangidwe ka mankhwala, kulondola kwa zinthu, ndi kukhwima kwakukulu kwa pamwamba pa zinthu zonse zaperekedwa.
