S890QL Yakadzimwa uye Yakapfava Chimiro Chesimbi
Hot-Kuumba
Kupisa-kuumba pamusoro pe580 ° C kunogoneka. Kudzima kunotevera uye kupisa kunofanirwa kuitwa zvinoenderana nemamiriro ekutumira.
Kugaya
Kuchera necobalt-alloyed high-speed steels HSSCO. Kucheka kumhanya kunofanira kunge kuri 17 - 19 m/min. Kana madhiri eHSS akashandiswa, kumhanya kwekucheka kunofanirwa kunge kuri 3 - 5 m/min.
Kucheka-Murazvo
Tembiricha yechinhu chacho inofanira kunge iri RT yekucheka-murazvo. Pamusoro pezvo, tembiricha dzinotevera dzepamberi pekupisa dzinokurudzirwa kune mamwe makobvu eplate: Pakukora kwendiro inodarika 40mm, preheat kusvika 100°C uye pakukora kupfuura 80mm, preheat kusvika 150°C.
Welding
S890QL simbi inokodzera ese azvino welding nzira. Tembiricha yechinhu chacho inofanira kunge iri RT yewelding. Mukuwedzera, iyo inotevera preheating tembiricha inokurudzirwa kune mamwe maplate makobvu:
20mm - 40mm: 75°C
Kupfuura 40mm: 100°C
60mm uye pamusoro: 150°C
Aya maratidziro ndiwo akajairwa tsika chete, mumusimboti, zviratidzo zveSEW 088 zvinofanirwa kuteedzerwa.
Iyo t 8/5 nguva dzinofanira kunge dziri pakati pe5 ne25 s, zvichienderana nehunyanzvi hwekushongedza hunoshandiswa. Kana kudzikamisa kushushikana mupfungwa kuchidikanwa nekuda kwezvikonzero zvekuvaka, izvi zvinofanirwa kuitwa mukupisa kwe530°C-580°C.
