I-S890QL Ecinyiweyo kunye neNtsimbi yoLwakhiwo oluPhumayo
Okushushu-Ukwenza
Ukutshisa okutshisa ngaphezu kwe-580 ° C kunokwenzeka. Ukucinywa okulandelayo kunye nokuthambisa kufuneka kuqhutywe ngokwemiqathango yokuhanjiswa.
Ukugaya
Ukugaya ngeentsimbi ze-cobalt-alloyed high-speed HSSCO. Isantya sokusika kufuneka sibe malunga ne-17 - 19 m/min. Ukuba i-HSS drills isetyenzisiweyo, isantya sokusika kufuneka sibe malunga ne-3 - 5 m/min.
Idangatye-Ukusika
Ubushushu bezinto eziphathekayo kufuneka bube yi-RT ubuncinane bokusika umlilo. Ukongeza, la maqondo obushushu alandelayo alandelayo ayacetyiswa kubunzima bepleyiti ethile: Kubunzima beepleyiti ezingaphezulu kwe-40mm, shushubeza ngaphambili ukuya kwi-100°C kunye nobukhulu obungaphezulu kwe-80mm, shushumbisa ukuya kwi-150°C.
Ukuwelda
Intsimbi ye-S890QL ifanelekile kuzo zonke iindlela ze-welding zangoku. Ubushushu bezinto eziphathekayo kufuneka bube ubuncinane be-RT ye-welding. Ukongeza, la maqondo obushushu alandelayo ayacetyiswa kubunzima bepleyiti ethile:
20mm – 40mm: 75°C
Ngaphezulu kwe-40mm: 100°C
60mm nangaphezulu: 150°C
Ezi zalathisi ziinqobo ezisemgangathweni kuphela, ngokomgaqo, iimpawu ze-SEW 088 kufuneka zithotyelwe.
Ixesha le-t 8/5 kufuneka libe phakathi kwe-5 kunye ne-25 s, kuxhomekeke kubuchule be-welding esetyenzisiweyo. Ukuba i-stress annealing iyimfuneko ngenxa yezizathu zokwakha, oku kufuneka kwenziwe kwiqondo lobushushu elingama-530°C-580°C.
