Mark Ford, woyang'anira chitukuko chabodza ku AFG Industries, Inc., akufotokoza:
Galasi yotentha imakhala yamphamvu kuwirikiza kanayi kuposa galasi "wamba," kapena annealed, galasi. Ndipo mosiyana ndi magalasi opindika, omwe amatha kusweka kukhala tizigawo tating'onoting'ono akathyoka, magalasi osapsa aphwanyika kukhala tizidutswa tating'ono, topanda vuto lililonse. Zotsatira zake, magalasi otenthetsera amagwiritsidwa ntchito m'malo omwe chitetezo chamunthu chimakhala vuto. Mapulogalamuwa akuphatikiza mazenera am'mbali ndi akumbuyo m'magalimoto, zitseko zolowera, malo osambira ndi ma chubu, mabwalo amasewera a racquetball, mipando yapabwalo, mauvuni a microwave ndi ma skylights.
Kukonzekera galasi la kutentha, liyenera kudulidwa kaye kukula komwe mukufuna. (Kuchepetsa mphamvu kapena kulephera kwa mankhwala kumatha kuchitika ngati ntchito zilizonse zopangira, monga etching kapena edging, zimachitika pambuyo pa chithandizo cha kutentha.) Galasiyo imawunikidwa chifukwa cha zolakwika zomwe zingayambitse kusweka pa sitepe iliyonse panthawi ya kutentha. Chonyezimira chonga ngati sandpaper chimatenga mbali zakuthwa kuchokera pagalasi, zomwe pambuyo pake zimachapidwa.
KUTENGATSA
Kenaka, galasiyo imayamba ntchito yochizira kutentha yomwe imadutsa mu uvuni wotentha, kaya ndi batch kapena chakudya chopitirira. Uvuni umatenthetsa galasi mpaka kutentha kwa madigiri 600 Celsius. (Muyezo wamakampani ndi 620 digiri Celsius.) Galasiyo imadutsa njira yoziziritsa kwambiri yotchedwa "quenching." Panthawi imeneyi, yomwe imatenga masekondi pang'ono, mpweya wothamanga kwambiri umaphulika pamwamba pa galasi kuchokera kumatope osiyanasiyana omwe ali m'malo osiyanasiyana. Kuzimitsa kumazizira kunja kwa galasi mwachangu kwambiri kuposa pakati. Pamene pakatikati pa galasilo amazizira, amayesa kukokera kumbuyo kuchokera kunja. Chotsatira chake, pakati pamakhala chipwirikiti, ndipo malo akunja amapita kukanikizana, zomwe zimapereka galasi lotentha mphamvu yake.
Galasi yomwe ili ndi mphamvu imasweka pafupifupi kasanu kuposa momwe imachitira popanikiza. Magalasi a Annealed adzasweka pa 6,000 pounds per square inch (psi). Magalasi otenthedwa, malinga ndi zomwe boma likunena, liyenera kukhala ndi kuponderezedwa kwa 10,000 psi kapena kupitilira apo; nthawi zambiri imasweka pafupifupi 24,000 psi.
Njira ina yopangira magalasi otenthedwa ndi kutentha kwa mankhwala, komwe mankhwala osiyanasiyana amasinthanitsa ma ion pamwamba pa galasi kuti apange kuponderezana. Koma chifukwa chakuti njira imeneyi imawononga ndalama zambiri kuposa kugwiritsa ntchito uvuni wotenthetsera ndi kuzimitsa moto, siigwiritsidwa ntchito kwambiri.
