A ithubhu yethusiIndlela yokulawula ukushisa I-copper tube synchronous spray water cooling cutting device ibhentshi yokusebenza, indawo engezansi yebhentshi ifakwe izinyawo ezisekela nhlangothi zombili, kanti ingxenye engaphezulu kwesokunxele yebhentshi ifakwe ipuleti lokubeka, Ithoshi ye-plasma ifakwe phezulu kwepuleti lokusekela, isihlalo esingaguquki sifakwe phezulu kwesisekelo, futhi i-nozzle ifakwe ngaphakathi kwekhola engaguquki, futhi umlomo wombhobho uxhunywe kwipompo yamanzi ngepayipi lokuqondisa amanzi.
Ithubhu yethusi ifafazwa ngokulinganayo ngamanzi ukuze ipholise inqubo yokusika.Lapho ithoshi yokusika i-plasma isetshenziselwa ukusika ithubhu yethusi, ama-bolts okulungisa akhululiwe, futhi ipompo yamanzi impompa amanzi agcinwe ku-tank yokuqoqa amanzi ngaphakathi kwepayipi yokuqondisa amanzi.Amanzi afafazwa nge-nozzle ukuze apholise umlomo wesibhamu sokusika i-plasma, okuqinisekisa ukupholisa kwesibhamu se-plasma cut cut, kugwema ukwenzeka kokulimala okushisayo kwesibhamu se-plasma cutting, kuqinisekisa ukuthi ukusika. umthungo weshubhu yethusi bushelelezi, futhi kuthuthukisa ukusebenza kahle komsebenzi.s ukusebenza kahle.
Indlela yokulawula ukushisa kwe-slab esithandweni sokushisa sensimbi, indlela yokulawula ukushisa ehlanganisa izinyathelo ezilandelayo: I-S1, ukuthola insimu yokushisa yesikhathi sangempela se-slab esithandweni sokushisa;I-S2, ilawula Imingcele yokusebenza yedivayisi evuthayo endaweni yomlilo we-slab.Ngesikhathi esifanayo, uhlelo lokulawula ukushisa kwesithando somlilo we-steel rolling lokushisa ngokusho kwendlela yokulawula ukushisa eshiwo ngenhla luyadalulwa.Ngohlelo lobuchwepheshe olubalulwe ngenhla, ngokusho kokulawulwa kwenkundla yokushisa kwesikhathi sangempela kwe-slab Imingcele yomlilo yedivayisi evuthayo yokushisisa i-slab, ukuze ubone ukushisa okunembile kwama-slabs emazingeni okushisa ahlukene okungena esithandweni, ukuthuthukisa lawula ukunemba kwezinga lokushisa eliqondiwe le-slab eliphuma esithandweni, futhi unciphise ukusetshenziswa kwamandla nokulahlekelwa kwe-oxidation ngesikhathi esifanayo.Inqubo yokugoba yamashubhu ethusi anezindonga ezincane ezinodonga oluncane emishinini yeqhwa, ngemva kokuhlaziya ingcindezi nokucindezeleka enqubweni yokugoba kanye nezimbangela zezinkinga ezihlukahlukene zekhwalithi, yenze izinqubo zokugoba, ukuthambisa, kanye nokugoba ishubhu yethusi.Idizayini ngokwezici zokuguquguquka kwezinto I-faying yokugoba ipayipi yasungulwa, futhi i-groove ephikisana ne-deformation kanye ne-pipe egoba i-mandrel yasetshenziselwa ukuxazulula iziphambeko zokushwabana konqenqema lwangaphakathi kanye nokucaba komphetho wangaphandle phakathi nenqubo yokugoba.Umkhuba wokukhiqiza ufakazele ukuthi umklamo wenqubo unengqondo, isakhiwo sesikhunta silula futhi siyasebenza, kanye nemikhiqizo ecutshungulwayo Ikhwalithi enhle, ifanele ukukhiqizwa kwenqwaba encane.Intambo yokushisela ye-arc engaphansi kwamanzi yensimbi yepayipi lamandla aphezulu kanye nendlela yayo yokulungiselela.Uhlelo lobuchwepheshe luwukuthi: izingxenye zocingo lokushisela i-arc olungaphansi kwamanzi yilezi: C ngu-0.040.06wt%, uMn ngu-1.402 .00wt%, i-Mo ingu-0.701.10wt%, i-Ni ingu-2.002.60wt%, i-Cr ingu-0.801.20wt% I-Cu ingu-0.100.30wt%, B≤0.0005wt%, S≤0.01wt%, P≤0.01wt%, Ibhalansi ingu-Fe nokungcola okungagwemeki;inqubo yokulungiselela imi kanje: engeza izithasiselo eziyinhlanganisela ezingu-0.010.5wt% ekuncibilikisweni ngokuvumelana nezingxenye ezingenhla, uphonswe ku-billet, i-hot-roll ibe yizintambo zezintambo ezingu-Φ5.5Φ7.5mm, bese ususa isikali esingaphezulu, esidonswe ku-Φ3.2Φ4 .0mm intambo yokushisela, efakwe ngethusi.Isengezo esihlanganisiwe sengezwa ngendlela yocingo olunezintambo.Intambo yokushisela elungiselelwe ekusungulweni kwamanje ifaniswe ne-SJ105 flux yokushisela, futhi amandla aqinile ensimbi yokushisela angu-σ≥910MPa;insimbi yokushisela- 30°C ukuqina komthelela A≥84J, ilungele ukushiselwa kwe-arc engaphansi kwamashubhu ekhopha angu-t2.
