Munguva pfupi yapfuura, standard yenyika GB/T20878-2024 "Stainless Steel Grades and Chemical Compositions", yakagadziriswa neMetallurgical Industry Information Standards Research Institute uye yakatorwa neFujian Qingtuo Special Steel Technology Research Co., Ltd. nedzimwe mayuniti, yakaburitswa uye ichatanga kushanda musi wa1 Kukadzi, 2025. Mushure memakore anoda kusvika matanhatu ekuedza nekushingaira, Qingtuo Group yakagadzira yakazvimiririra mhando dzeQN dzesimbi isina ngura dzine nitrogen yakasimbiswa zvakanyanya, dzinosanganisira S35250 (QN1701), S25230 (QN1801), S35657 (QN1803), S35656 (QN1804), S35388 (Zvigadzirwa zvine mwero wakasiyana wekudzivirira ngura senge QF1804), S35706 (QN2008), S35886 (QN1906) uye S35887 (QN2109) zvakabatanidzwa muchiyero ichi, zvichiwedzera chimiro chesimbi isina ngura uye zvichipa simba rakawanda, rakareruka, uye kudzivirira ngura kwakanyanya mumunda wezvivakwa zvinotakura mutoro. Hurongwa hwekuzadzisa mhando dzesimbi dzisina ngura dzakachengeteka zvakanyanya uye dzinoshanda zvakanaka.
S35656 (QN1804) inovimba nekugona kwayo kudzikamisa ngura, kuchinjika kwayo uye hunhu hwayo hwemakanika husina kupisa zvakanyanya kuti huvepo muGB/T150.2-2024 "Midziyo Yekumanikidza Chikamu 2: Zvinhu" uye GB/T713.7-2023 "Ndege Yesimbi neSimbi Yemidziyo Yekumanikidza" Ine Chikamu 7: Simbi Isina Simba uye Simbi Inodzivirira Kupisa" uye mimwe mitemo miviri yenyika ine chekuita nemidziyo yekumanikidza. Mumakore mashoma apfuura, QN series stainless steel yakagadzira cheni yeindasitiri yakagadzikana uye yakashandiswa muzvikamu zvakasiyana-siyana mumisika yezvivakwa zvinotakura mutoro senge high-speed njanji tunnel engineering, zvivakwa zvakagadzirwa kare, subway engineering, simba, ocean engineering uye midziyo yekumanikidza.
Kupukuta kwemagetsiinzira yekupedzisa nemagetsi inobvisa jira rakatetepa resimbi, kazhinji simbi isina ngura kana zvimwe zvakafanana. Maitiro acho anosiya kupenya, kwakapfava, uye kwakachena zvakanyanya.
Inozivikanwawo sekupukuta kwemagetsi, kupukuta kweanodickanakukwesha kwemagetsi, electropolishing inonyanya kubatsira pakupukuta uye kubvisa maburi ezvikamu zvisina kusimba kana kuti zvine geometries dzakaoma. Electropolishing inovandudza kupenya kwenzvimbo nekuderedza kuomarara kwenzvimbo kusvika ku50%.
Kupolisha kwemagetsi kunogona kufungidzirwa seelectroplating yekumashurePanzvimbo pekuwedzera kufukidza kwakatetepa kwemaion esimbi ane chaji yakanaka, electropolishing inoshandisa magetsi emagetsi kunyungudutsa jira rakatetepa remaion esimbi kuita electrolyte solution.
Kupukuta simbi isina ngura nemagetsi ndiko kunonyanya kushandiswa pakupukuta simbi isina ngura nemagetsi. Simbi isina ngura ine ngura yakapfava, inopenya, uye yakachena zvikuru inodzivirira ngura. Kunyangwe simbi chero ipi zvayo ichizoshanda, simbi dzinonyanya kupukuta nemagetsi isimbi isina ngura ine 300- uye 400-series.
Kupedzisa kwe electroplating kune mwero wakasiyana wekushandiswa mumashandisirwo akasiyana. Mashandisirwo aya anoda kupedzisa kwepakati nepakati. Kugadzirisa electropolishing inzira ine electropolished Stainless Steel Pipe ine roughness yakakwana. Izvi zvinoita kuti mapaipi ave akarurama uye EP Pipe inogona kuiswa nemazvo mumasystem anonzwa sengekushandiswa kwemishonga mumaindasitiri.
Tine michina yedu yekupukuta uye tinogadzira machubhu ekupukuta emagetsi anoenderana nezvinodiwa neminda yakasiyana-siyana tichitungamirirwa nechikwata chehunyanzvi chekuKorea.
Tubhu yedu yeEP ine mamiriro ekunze emukamuri eISO14644-1 Kirasi 5, chubhu yega yega inocheneswa nekuchena kwakanyanya (UHP)nitrogen yozovharwa nevharo uye yoiswa mumabhegi maviri. Chitupa chinoratidza mwero wekugadzirwa kwechubhu, kuumbwa kwemakemikari, kutevedza zvinhu, uye kuomarara kwepamusoro pechinhu chose chinopihwa.
