I-S890QL Insimbi Ecishiwe Neqinile Yesakhiwo
Okushisayo-Ukwakha
Ukushisa okungaphezulu kuka-580°C kungenzeka. Ukucisha nokushisa okulandelayo kufanele kwenziwe ngokuya ngemibandela yokulethwa.
Ukugaya
Ukubhoboza ngezinsimbi ze-cobalt-alloyed high-speed HSSCO. Ijubane lokusika kufanele libe ngu-17 - 19 m/min. Uma kusetshenziswa imishini ye-HSS, isivinini sokusika kufanele sibe cishe ku-3 - 5 m/min.
I-Flame-Cutting
Izinga lokushisa lempahla kufanele okungenani libe yi-RT yokusika amalangabi. Ukwengeza, amazinga okushisa alandelayo okushisa alandelayo ayatuswa ngobugqinsi bepuleti elithile: Ngobukhulu bepuleti obungaphezu kuka-40mm, shisa kuqala uye ku-100°C futhi uma kunogqinsi olungaphezu kuka-80mm, shisa kuqala uye ku-150°C.
Ukushisela
Insimbi ye-S890QL ifanele zonke izindlela zokushisela zamanje. Izinga lokushisa impahla kufanele okungenani RT for Welding. Ngaphezu kwalokho, amazinga okushisa okushisa alandelayo anconywa ngokuqina kwepuleti elithile:
20mm – 40mm: 75°C
Ngaphezulu kuka-40mm: 100°C
60mm nangaphezulu: 150°C
Lezi zinkomba zingamagugu ajwayelekile kuphela, ngokomthetho, izinkomba ze-SEW 088 kufanele zilandelwe.
Izikhathi ze-t 8/5 kufanele zibe phakathi kuka-5 no-25 s, kuye ngokuthi inqubo yokushisela esetshenzisiwe. Uma kwenzeka ukuncishiswa kwe-stress annealing kudingekile ngenxa yezizathu zokwakha, lokhu kufanele kwenziwe ezingeni lokushisa elingu-530°C-580°C.
