Ukuveliswa kwemibhobho yentsimbi ye-alloy ephezulu
Indlela yokuvelisa ipayipi yensimbi engenamthungo ihlukaniswe ngokufanelekileyo kwindlela yokuwela (indlela yeMennesmann) kunye nendlela yokukhupha.Indlela ye-cross-rolling (indlela ye-Mennesmann) kukuqala ukubhobhoza i-tube engenanto kunye ne-cross-roller, kwaye emva koko iyandise nge-rolling mill.Le ndlela inesantya esikhawulezayo sokuvelisa, kodwa ifuna ukuchaneka okuphezulu kwetyhubhu engenanto, kwaye ilungele ukuveliswa kwentsimbi yekhabhoni kunye neetyhubhu zentsimbi ezisezantsi.
Indlela ye-extrusion kukubhobhoza i-tube engenanto okanye i-ingot ngomatshini wokubhoboza, kwaye emva koko uyikhuphe kumbhobho wentsimbi kunye ne-extruder.Le ndlela ayisebenzi kakuhle kunendlela ye-skew rolling kwaye ifanelekile ukuveliswa kwemibhobho yensimbi ye-alloy ephezulu.
Zombini indlela ye-skew rolling kunye ne-extrusion method kufuneka iqale ukutshisa i-tube engenanto okanye i-ingot, kwaye ityhubhu yensimbi eveliswayo ibizwa ngokuba ityhubhu eshushu.Imibhobho yentsimbi eveliswa ngeendlela zokusebenza ezishushu ngamanye amaxesha inokusetyenzwa ngokubanda njengoko kufuneka.
Kukho iindlela ezimbini zokusebenza okubandayo: enye yindlela yokudweba ebandayo, ekukuzoba umbhobho wentsimbi ngomzobo wokufa ukuze uncinci kwaye ukhulise umbhobho wensimbi;
Enye indlela yindlela yokuqengqeleka ebandayo, eyindlela yokugalela ilitye lokungqusha elishushu elenziwe ngabakwaMennesmann Brothers ekusebenzeni ngokubanda.Ukusebenza okubandayo kombhobho wensimbi engenamthungo kunokuphucula ukuchaneka kwe-dimensional kunye nokugqiba ukucutshungulwa kombhobho wensimbi, kunye nokuphucula iimpawu zomatshini zezinto.
Inkqubo yokuvelisa umbhobho wentsimbi engenamthungo (ipayipi yentsimbi eshushu-eshushu)
I-seamlessness yombhobho wentsimbi igqitywe ngokukodwa ngokucutha ukuxhatshazwa, kwaye inkqubo yokunciphisa uxinzelelo yinkqubo eqhubekayo yokuqengqeleka kwesiseko sesinyithi esingenanto ngaphandle kwe-mandrel.Phantsi komqathango wokuqinisekisa umgangatho wokuwelda wombhobho womzali, inkqubo yokunciphisa uxinzelelo lombhobho wokuwelda kukufudumeza umbhobho odityanisiweyo uphelele ukuya kumaqondo angaphezu kwama-950 ngokukaCelsius, uze uwuqengqele kwiidayamitha ezahlukeneyo zangaphandle neendonga ngesinciphisi soxinzelelo ( Iyonke i-24 ipasisiwe ye-tension reducer).Kwimibhobho egqitywe engqindilili, imibhobho yentsimbi eshushu eqengqelekayo eveliswa yile nkqubo yahluke kakhulu kwimibhobho eqhelekileyo edityanisiweyo ephezulu.Ukuqengqeleka koxinzelelo lwesibini kunye nolawulo oluzenzekelayo lwenza ukuchaneka komgangatho wombhobho wentsimbi (ngokukodwa ukujikeleza kunye nokuchaneka kodonga lomzimba wombhobho) ngcono kunoko lwemibhobho efanayo engenamthungo.
