2. Fetola mekhoa ea ho taka ea tanka ea metsi
Ho ea ka mokhoa o tiileng oa setšoantšo sa sekhahla sa khatello e fokolang ea li-multi-pass, tekanyo ea khatello ea kakaretso ke 96.48%, e fokotsang ho hlajoa ha lesela la zinki.Mohaho oohle oa terata o entsoe ka tungsten steel die le polycrystalline die.Angle ea khoune e sebetsang ea mochini oa terata ke 12 ° ~ 16 °, 'me bolelele ba lebanta la boholo ke 0.15 ea bophara ba terata, e le ho netefatsa hore deformation ea lesela la zinki e lumellana hantle le tšepe terata substrate.
Mokhoa oa ho potoloha o pholileng o sebelisa spray ho pholisa lefu la ho taka, 'me o tlosa mocheso o mongata o hlahisoang ke mochine oa ho taka ka lebelo le phahameng ka nako ho netefatsa boleng ba terata.Laola mehato ea ts'ebetso ea ho taka: lebelo la ho taka 10 ~ 12m / s;Maqhubu a tsitsipano 8 ~ 10N;Ho lekanya bolelele ba 30km;Karolo e boima ea mafura ke 3.5 ~ 4.5%;pH boleng ba lubricant 7 ~ 8;Lubricant mocheso 30 ~ 40 ℃.
Ka mor'a ho ntlafatsa ts'ebetso, tlhahiso ea boima ba 0.80mm electroterata ya tshepeElectro galvanized zinki lera boleng e laoloa ka hare ho 80 ~ 90g/m2, zinki lera boleng hasana e nyenyane haholo;Liphetho li bonts'a hore boima bo tloaelehileng ba lesela la zinki ke 14.5g / m2, tahlehelo ea lesela la zinki e ka tlase ho 5%, 'me matla a matla a terata ea tšepe ke 2300 ~ 2500MPa.Ha e laole hantle feela boleng ba zinki lera la terata e tala ea tšepe, empa hape e fokotsa litšila tse sa hlokahaleng le litšenyehelo tsa tlhahiso.
