Munguva pfupi yapfuura, iyo yenyika standard GB/T20878-2024 "Stainless Simbi Magiredhi uye Chemical Compositions", yakagadziriswa neMetallurgical Indasitiri Information Standards Research Institute uye yakatora chikamu naFujian Qingtuo Special Steel Technology Research Co., Ltd. uye zvimwe zvikamu, yakaburitswa uye ichaita ichaitwa muna Kukadzi 1, 2025. . Mushure memakore anoda kusvika matanhatu ekuedza kusingadzoreki, Qingtuo Boka rakazvimiririra rakagadzira nitrogen-ine yakanyanya kusimbiswa austenitic Stainless simbi QN yakatevedzana, kusanganisira S35250 (QN1701), S25230 (QN1801), S35657 (QN1803), S35656 (QN380 yakasiyana), S35656 (QN380) ngura kuramba mazinga akadai seQF1804), S35706 (QN2008), S35886 (QN1906) uye S35887 (QN2109) yakaverengerwa mune iyi chiyero, ichipfumisa simbi isina tsvina dhizaini uye ichipa yakakwira simba, huremu, uye yakakwirira corrosion kuramba kwendima yezvimiro zvinotakura. . Urongwa hwekuita hwemhando dzesimbi dzisina simbi dzine kuchengetedzwa kwepamusoro uye zvinodhura-zvinobudirira.
S35656 (QN1804) inovimba neayo yakanakisa corrosion kuramba, weldability uye yakaderera-tembiricha michina zvivakwa kuti zviiswe muGB/T150.2-2024 “Pressure Vessels Part 2: Materials” uye GB/T713.7-2023 “Simbi Plate neSimbi Zvekumanikidza Equipment” NeChikamu 7: Stainless Simbi uye Heat-Resistant Steel" uye mamwe maitiro maviri enyika ane hukama nemidziyo yekumanikidza. Mumakore mashoma apfuura, QN yakatevedzana simbi isina tsvina yakagadzira cheni yakagadzikana yemaindasitiri uye yakashandiswa mumabhechi mumisika yakawanda inotakura-inotakura zvimiro zvemusika senge high-speed njanji tunnel engineering, prefabricated zvivakwa, subway engineering, simba, ocean engineering uye. midziyo yekumanikidza.
Electropolishingielectrochemical finishing process inobvisa chidimbu chechinhu kubva muchikamu chesimbi, kazhinji simbi isina tsvina kana alloys akafanana. Iyo nzira inosiya inopenya, yakatsetseka, yakanyanya kuchena pamusoro pekupedzisira.
Uyewo anozivikanwa seelectrochemical polishing, anodic polishingkanaelectrolytic polishing, electropolishing inonyanya kubatsira pakukwenenzvera nekubvisa mativi asina kusimba kana ane geometries yakaoma. Electropolishing inonatsiridza kupera kwepasi nekudzikisa kushata kwepamusoro kusvika pa50%.
Electropolishing inogona kufungidzirwa sereverse electroplating. Panzvimbo pekuwedzera jira rakatetepa reiyoni yesimbi inochajiswa zvakanaka, electropolishing inoshandisa electric current kunyungudutsa nhete yeioni dzesimbi mumhinduro ye electrolyte.
Electropolishing yesimbi isina tsvina ndiyo inonyanya kushandiswa kwe electropolishing. Electropolished Stainless simbi ine yakatsetseka, inopenya, yakanyatsochenesesa inopedza ngura. Kunyangwe simbi chero ipi zvayo ichashanda, simbi dzinowanzoitwa nemagetsi ndeye 300- uye 400-yakatevedzana simbi isina tsvina.
Kupedzwa kwe electroplating kune zviyero zvakasiyana zvekushandisa mumashandisirwo akasiyana. Zvikumbiro izvi zvinoda pakati pekupedzisira. Electropolishing inzira kuburikidza nekukasharara kweElectropolished Stainless Steel Pipe inodzikiswa. Izvi zvinoita kuti mapaipi awedzere kurongeka muhukuru uye iyo EP Pipe inogona kuisirwa nekurongeka mumasisitimu anonzwisisika sengemishonga yemaindasitiri application.
Isu tine yedu yekupukuta michina uye tinogadzira electrolytic polishing machubhu anoenderana nezvinodiwa zveakasiyana minda pasi pekutungamirwa neKorea tekinoroji timu.
Yedu EP Tube mu ISO14644-1 Kirasi 5 yakachena kamuri mamiriro, imwe neimwe chubhu inocheneswa nayo.Kuchena kwepamusoro (UHP)nitrogen uye wozovharwa uye wakapetwa kaviri. Certification inokodzera kugadzirwa kwetubhing, kuumbwa kwemakemikari, kuteedzera zvinhu, uye kunyanyisa kwepamusoro kuomarara kunopihwa kune zvese zvinhu.
