S890QL Yozimitsidwa Ndi Chitsulo Chokhazikika
Kutentha-Kupanga
Kupanga kutentha pamwamba pa 580 ° C ndikotheka. Kuzimitsa ndi kutentha kotsatira kuyenera kuchitidwa molingana ndi momwe akuperekera.
Kugaya
Kubowola ndi zitsulo zothamanga kwambiri za cobalt HSSCO. Kudula kuyenera kukhala pafupifupi 17 - 19 m/min. Ngati mabowo a HSS agwiritsidwa ntchito, liwiro lodulira liyenera kukhala pafupifupi 3 - 5 m/min.
Kudula Moto
Kutentha kwa zinthuzo kuyenera kukhala osachepera RT pakuwotcha moto. Kuphatikiza apo, kutentha kotsatiraku kumalimbikitsidwa pa makulidwe ena a mbale: Pa makulidwe a mbale kupitirira 40mm, preheat mpaka 100°C ndi makulidwe a 80mm, preheat mpaka 150°C.
Kuwotcherera
Chitsulo cha S890QL ndichoyenera njira zonse zowotcherera. Kutentha kwa zinthuzo kuyenera kukhala osachepera RT pakuwotcherera. Kuphatikiza apo, kutentha kotsatiraku kumalimbikitsidwa pa makulidwe ena a mbale:
20mm - 40mm: 75°C
Kupitilira 40mm: 100°C
60mm ndi kupitirira: 150°C
Zizindikirozi ndizokhazikika zokhazokha, makamaka, zizindikiro za SEW 088 ziyenera kutsatiridwa.
Nthawi za t 8/5 ziyenera kukhala pakati pa 5 ndi 25 s, kutengera njira yowotcherera yomwe imagwiritsidwa ntchito. Kuchepetsa kupsinjika kwapakati pakakhala kofunikira pazifukwa zomanga, izi zikuyenera kuchitika pa kutentha kwa 530°C-580°C.
