A ityhubhu yobheduIndlela yokulawula ukufudumeza I-tube yobhedu yokutshiza i-spray yokupholisa isixhobo sokupholisa isixhobo sokusebenza, isiphelo esisezantsi sebhentshi sixhotyiswe ngeenyawo ezixhasayo kumacala omabini, kwaye icala eliphezulu lasekhohlo lendawo yokusebenza lixhotyiswe ngepleyiti yokubeka, Itotshi yeplasma ifakwe kuyo. phezulu kweplate yokuxhasa, isihlalo esisisigxina sifakwe phezulu kwinkxaso, kwaye i-nozzle ifakwe ngaphakathi kwikhola ehleliweyo, kwaye i-nozzle ixhunywe kumpompo wamanzi ngombhobho wesikhokelo samanzi.
I-tube yobhedu ifafazwe nge-synchronously ngamanzi ukupholisa inkqubo yokusika.Xa i-torch yokusika i-plasma isetyenziselwa ukusika ityhubhu yobhedu, iibholiti zokulungisa zikhululekile, kwaye ipompo yamanzi ipompoza amanzi agcinwe kwitanki yokuqokelela amanzi ngaphakathi kumbhobho wesikhokelo samanzi.Amanzi atshizwe ngaphandle kwi-nozzle ukupholisa umlomo we-plasma cutting gun, eqinisekisa ukupholisa kwe-nozzle ye-plasma cut gun, inqanda isiganeko somonakalo wokushisa we-nozzle ye-plasma cut gun, iqinisekisa ukuba ukusika. Umthungo wetyhubhu yobhedu ugudile, kwaye uphucula ukusebenza kakuhle.s ukusebenza kakuhle.
Indlela yokulawula ukufudumeza kwe-slab kwi-steel rolling furnace, indlela yokulawula ukufudumala equka la manyathelo alandelayo: I-S1, ukufumanisa intsimi yokushisa kwexesha langempela le-slab kwisithando sokufudumala;I-S2, ukulawula iiparamitha zokusebenza zesixhobo sokutsha kwindawo yesithando somlilo we-slab.Ngelo xesha, i-steel rolling yokufudumeza i-slab yokulawula ukufudumeza inkqubo yokufudumala ngokwendlela yokulawula ukufudumeza okukhankanywe ngasentla ibonakaliswe.Ngokusebenzisa isikimu sobugcisa esikhankanywe ngasentla, ngokwexesha langempela lokulawula intsimi yokushisa kwe-slab Iiparamitha zokutsha zesixhobo sokutshisa ukufudumeza i-slab, ukwenzela ukuba uqaphele ukufudumeza okuchanekileyo kwee-slabs kwiiqondo ezahlukeneyo zokungena eziko, ukuphucula i-slab. lawula ukuchaneka kokushisa okujoliswe kuyo kwe-slab ngaphandle kwesithando somlilo, kunye nokunciphisa ukusetyenziswa kwamandla kunye nokulahlekelwa kwe-oxidation ngexesha elifanayo.Inkqubo yokugoba yeetyhubhu zobhedu ezinodonga olucekethekileyo kwizixhobo zomkhenkce, emva kokuhlalutya uxinzelelo kunye noxinzelelo kwinkqubo yokugoba kunye nezizathu zeengxaki ezahlukeneyo zomgangatho, iye yaqulunqa iinkqubo zokugoba, ukuthambisa, kunye netyhubhu yobhedu.Uyilo ngokweempawu deformation izinto Umbhobho ukugoba die yaphuhliswa, kunye groove anti-deformation kunye nombhobho ukugoba mandrel zasetyenziswa ukusombulula iziphene ukushwabana komphetho wangaphakathi kunye flattening komphetho wangaphandle ngexesha lenkqubo ukugoba.Ukwenziwa kwemveliso kubonakalise ukuba inkqubo yoyilo lwenkqubo lunengqiqo, isakhiwo sokubumba silula kwaye sisebenza, kunye neemveliso ezicutshungulwayo Umgangatho olungileyo, ufanelekile kwimveliso encinci yebhetshi.Intambo yokuwelda entywiliselweyo yentsimbi yombhobho wokuqina ophezulu kakhulu kunye nendlela yokuyilungisa.Inkqubo yobugcisa yile: amacandelo e-arc welding wire ephantsi kwamanzi: C yi-0.040.06wt%, i-Mn yi-1.402 .00wt%, i-Mo yi-0.701.10wt%, i-Ni yi-2.002.60wt%, i-Cr yi-0.801.20wt% I-Cu yi-0.100.30wt%, B≤0.0005wt%, S≤0.01wt%, P≤0.01wt%, Ibhalansi yi-Fe kunye nokungcola okungenakuphepheka;inkqubo yokulungiselela imi ngolu hlobo lulandelayo: yongeza i-0.010.5wt% izongezo ezidibeneyo kwi-smelting ngokwamacandelo angentla, iphoswe kwiibhilidi, i-hot-roll ibe yi-Φ5.5Φ7.5mm yocingo, kwaye ususe isikali somgangatho, utsalwe kwi-Φ3.2Φ4 .0mm ucingo welding, copper-plated.I-additive composite yongezwa ngendlela yocingo oludibeneyo.I-wire welding elungiselelwe kwi-invention yangoku ihambelana ne-SJ105 flux ye-welding, kunye nokuqina kokuqina kwentsimbi ye-weld yi-σ≥910MPa;i-weld metal- 30 °C impembelelo yokuqina kwe-A≥84J, ilungele i-arc ye-arc efakwe emanzini ye-t2 iityhubhu zobhedu.
