Mafunso Ofunsidwa Kawirikawiri (FAQ) - Zonse zatsopano
Q: N’chifukwa chiyani miphika ikuluikulu ya slag iyenera kukhala yopangidwa ndi chinthu chimodzi osati yolumikizidwa?
Yankho: Misomali yolumikizidwa m'miphika ikuluikulu imakumana ndi kusiyana kwakukulu kwa kutentha (1,600°C mkati ndi kunja). Kusalingana kwa kutentha kumapangitsa kuti ming'alu ya kutopa ikhale pa zala za weld m'magawo ochepa ngati 2,000. Kuyika kwa Integral kumachotsa mizere yonse ya weld, ndikugawa kupsinjika mofanana kudzera mu chitsulo chofanana.
Q: Kodi mumayesa bwanji mphika wa slag wa matani 100 kuti muwone ngati pali zolakwika zobisika?
Yankho: Timaphatikiza mayeso odziyimira pawokha a ultrasound (AU) ndi phased array kuti tifufuze voliyumu 100%, kuphatikiza thermography panthawi yotenthetsera, komanso kuyang'anira tinthu tating'onoting'ono ta maginito pamalo onse. Malo a Trunnion amadutsa nthawi yowonjezera ya diffraction (TOFD) kuti azindikire ming'alu.
Q: Kodi tingagwiritse ntchito mphika womwewo wa slag pa ntchito zonse za BOF ndi EAF?
A: Sikoyenera. BOF slag ndi yothira madzi koma imakhala ndi mphamvu zambiri zamagetsi; EAF slag imakhala ndi kukhuthala kwakukulu ndipo imakhala ndi zitsulo. Timapanga ma ngodya a makoma a mphika ndi zipilala makamaka pa ntchito imodzi. Miphika yogwiritsidwa ntchito kawiri nthawi zambiri sigwira ntchito bwino.
Q: Kodi nthawi yotumizira ya mphika wa slag wa matani 70 ndi yotani?
A: Masabata 22-26 kuchokera pamene kujambula komaliza kuvomerezedwa. Izi zikuphatikizapo kupanga mapangidwe (masabata 4), kuyika ndi kutentha (masabata 6), NDT (masabata awiri), ndi kukonza/kuphimba (masabata awiri). Kuyitanitsa mwachangu n'kotheka ndi mapangidwe omwe alipo kale.
Q: Ndingathe kuyembekezera maulendo angati ndisanakonze koyamba?
A: Kutengera deta yathu kuchokera ku mill 38 yolumikizidwa, ma cycle apakati asanafike ming'alu iliyonse yodziwika pamwamba ndiMa cycle 8,200Kupera pang'ono kumatha kukulitsa moyo wa makinawa mpaka maulendo 12,000. Kukonzanso kwathunthu kumalimbikitsidwa zaka 10 zilizonse kapena maulendo 15,000.
Q: Kodi mungapereke miphika ya slag yokhala ndi njira yodziwira yokha slag kapena kuyang'anira kutentha?
Yankho: Inde. Tikhoza kuphatikiza ma thermocouple pansi pa mphika (ndi matumba oteteza) ndikuyika choyikira cha masensa a radar slag level. Ma waya amayikidwa mkati kuti apewe mabulaketi akunja.
Q: Kodi mulingo wakunja wotani womwe mungapange ndi wautali kwambiri?
Yankho: Chipangizo chathu chopangira zitsulo chimatha kuyika mphika m'mimba mwake mpaka mamita 3.6 (mainchesi 142). Miphika ikuluikulu imatha kupangidwa pogwiritsa ntchito kuyika ndi kuwotcherera m'magawo, koma tikukulimbikitsani kwambiri kuyika zinthu zonse kuti zigwire bwino ntchito.
Q: Kodi mumapereka chitsimikizo chowonjezera cha miphika yayikulu ya slag?
A: Timapereka chitsimikizo cha miyezi 18 / 5,000-cycle - chilichonse chomwe chimabwera poyamba. Ichi ndi kawiri kuposa muyezo wamakampani. Chitsimikizo chosankha chokhazikika pa magwiridwe antchito chingakambidwenso kuti mulandire maoda obwerezabwereza.
Q: Kodi mumatsimikiza bwanji mphamvu ya trunnion pambuyo pa maulendo angapo?
Yankho: Tikukulimbikitsani kuti muziyendetsa UT yonyamulika m'nyumba miyezi 12 iliyonse. Womic ikhoza kupereka zida zowunikira munda ndi maphunziro. Ngati zapezeka kuti zawonongeka kwambiri, ma trunnions amatha kuphimbidwa ndi chitsulo chosungunula ndikusinthidwa.
Q: Kodi mungapange mphika wa slag kuti ugwirizane ndi zokokera zathu za crane popanda kusintha crane?
A: Inde. Tikufuna kujambula mbiri ya mbedza ya crane (kuphatikiza m'lifupi mwa kutsegula mbedza, kuya kwa pakhosi, ndi utali wozungulira). Timagwirizanitsa mawonekedwe a trunnion ndi zida zanu zonyamulira zomwe zilipo.
Kodi mwakonzeka kukweza gulu lanu lalikulu la slag pot?
Lumikizanani ndi Womic Steel kuti mudziwe zambirindemanga yaukadaulo yopanda chikakamizoza makina anu ogwiritsira ntchito zinyalala omwe alipo panopa.
