Ukwandisa ukungqubuzana phakathi kwerola eyisiyingi nesigxobo esisele nokukhulisa i-engeli yomhlathi ochotshozayo kungenza ibhulokhi lensalela lebhola elinobubanzi obuyindilinga obukhudlwana lingene futhi lichoboze.Ngakho-ke, ama-flakes we-welding anobubanzi obungama-30 mm nobude obuyi-10 mm ahlanganiswe ngezikhathi ze-100 mm ebusweni be-roller ekhanyayo.Ngemuva kokuthi inqwaba esele ingene ekamelweni lokuchotshozwa, inqunywe ngaphansi kwesenzo sobuso bezinyo, futhi i-angle yomhlathi ochotshozayo yanda, futhi okusanhlamvu okujwayelekile kungatholakala.Ububanzi (6070mm) bukhulu futhi isigxobo esisele siphukile.
I-welding roller surface yenziwa ngokushisela i-arc manual, futhi ingaphezulu le-double-roller crusher lingaphezulu.Amaphuzu amqoka okubuka phezulu ami kanje.
(1) i-D-65, i-D-667 ne-506 ye-welding rods ikhethiwe.Ngaphambi kokushisela, ngokwemiyalo yezinduku zokushisela, izinduku zokushisela zomiswa bese zifakwa ku-incubator ukuze zisetshenziswe.
(2) Hlanza ungqimba lokukhathala lwe-roller surface, luhlanze nge-carbon arc gouging, bese uhlela ungqimba lokukhathala lwendawo yerola ukuze uveze i-roller kungqimba lwezinto eziyisisekelo.
(3) Sebenzisa umshini wokushisela we-DC, okufanele uguqulwe (induku yokushisela ixhunywe ku-electrode enhle).Uma uphezulu, umshini wokushisela we-AC udinga i-voltage engalayishiwe engu-70V, futhi yamanje ilawulwa cishe ku-200A.Uma i-voltage engekho umthwalo ingaphansi kuka-70V, okwamanje kufanele inyuswe, okusekelwe ekuhlanganiseni okugcwele kwe-electrode kanye nesisekelo sensimbi.Isilinganiso sobubanzi be-weld bead kuya ekuphakameni okungcono kakhulu ngu-31.
(4) Ngemva kokushisa kuqala umqulu, sebenzisa kuqala i-electrode engu-506 (i-alkaline electrode, elungele ukushisela impahla engu-16M, eshibhile, futhi ehlanganiswe kahle nesisekelo sensimbi) ukushisela izingqimba eziyi-13 ze-carbon steel, futhi uzungeleze umqulu.Bese ushisela ngokulinganayo izingqimba eziningana ze-D-667 (i-high-chromium cast iron surfacing rod ingamelana nomthelela omkhulu nokumelana nokugqoka, ukuqina kwe-HRC48 ngemva kokushisela, ukumelana nokugqokwa okuhle, ukumelana nokugqwala kanye nokumelana ne-cavitation ngaphansi kwezinga lokushisa eliphakeme elingu-500) Kufanele kube nogqinsi.Ngemuva kokuthi ungqimba olushiselayo lwe-D-667 luvele ngaphezulu, ungqimba lwe-D-65 (induku ephezulu yealloyi engaphezulu kwe-Cr-Si-Mo-B e-corrosion cast-iron ukumelana nokugqokwa kwensimbi engagqoki ingavela. Ingakwazi ukumelana Ukumelana nokuguga okuqinile, izinzuzo zale electrode zibukeka kahle, azikho i-slag ngemva kokushisela, ukumelana nokugqokwa okuphezulu. Ukuqina ngemva kokushisela i-HRC60. Thuthukisa impilo yokugqoka izikhathi ezingu-310), ukushuba kokungaphezulu kungu-35mm.Gqoka isendlalelo Ukucindezeleka kokuqina kufana ukuze i-roller ecindezelayo ihlale iyindilinga ngesikhathi sokusetshenziswa.
3 Isiphetho
Ngokuzijwayeza ukukhiqiza, isilinganiso sosayizi wezinhlayiyana ze-electrode eyinsalela ye-crusher iyakhuphuka isuka ku-40mm iye ku-60mm ngesikhathi sokuklama, okunciphisa umthwalo wokukhiqizwa kwemishini ekhuphuka nomfula, kuthuthukisa ukuguquguquka kwe-roller crusher, nempilo yesevisi i-roller crusher ifinyelela ku-10 Ngenyanga, isigxobo esisele esiphukile sibe amathani angama-50,000.
