Isici esinezibazi eshubhuni elingenamthungo eligoqekayo eliqhubekayo likhona endaweni engaphakathi yepayipi lensimbi, elifana nomgodi wosayizi wohlamvu lukabhontshisi wesoya. Iningi lezibazi zinento yangaphandle empunga-nsundu noma empunga-mnyama. Izici ezithonyayo zokulimala kwangaphakathi zihlanganisa: i-deoxidizer, inqubo yomjovo, i-mandrel lubrication nezinye izici. Ake silandele umkhiqizi wamashubhu ensimbi ye-carbon steel ukuze sibone ukuthi ungalawula kanjani ukukhubazeka kwangaphakathi kwamashubhu ensimbi angenamthungo:

1. I-Deoxidizer

I-oxide iyadingeka ukuze ibe sesimweni esincibilikisiwe lapho i-mandrel ibhobozwa ngaphambili. Amandla ayo nezinye izidingo eziqinile.

I-1) Usayizi wezinhlayiyana ze-deoxidizer powder ngokuvamile udingeka ukuthi ube ne-16 mesh.
I-2) Okuqukethwe kwe-sodium stearate ku-agent yokukhipha kufanele kufinyelele ngaphezu kwe-12%, ukuze kushise ngokugcwele ku-lumen ye-capillary.
I-3) Thola inani lomjovo we-deoxidizer ngokusho kwendawo yangaphakathi ye-capillary, ngokuvamile i-1.5-2.0g/dm2, futhi inani le-deoxidizer elifuthwe yi-capillary enobubanzi obuhlukene nobude buhlukile.

2. Imingcele yenqubo yokujova

I-1) Ukucindezela komjovo kufanele kuhambisane nobubanzi nobude be-capillary, okungagcini nje ngokuqinisekisa ukuvuthela okunamandla nokuvutha okwanele, kodwa futhi kuvimbele i-scavenger eshisiwe ngokungaphelele ukuba ikhishwe ku-capillary ngokugeleza komoya.
I-2) Isikhathi sokuhlanza somkhiqizi wepayipi lensimbi engenamthungo kufanele silungiswe ngokuvumelana nokuqondisa nobude be-capillary, futhi izinga liwukuthi ayikho i-oxide yensimbi emisiwe ku-capillary ngaphambi kokushaywa umoya.
I-3) Ukuphakama kwe-nozzle kufanele kulungiswe ngokuvumelana nobubanzi be-capillary ukuze kuqinisekiswe ukugxila okuhle. I-nozzle kufanele ihlanzwe kanye njalo njalo, futhi umlomo wombhobho kufanele ususwe ukuze uhlanzwe ngemva kokuvala isikhathi eside. Ukuze kuqinisekiswe ukuthi i-ejenti ekhipha i-deoxidizing ishaywa ngokulinganayo odongeni lwangaphakathi lwe-capillary, idivayisi yokuzikhethela isetshenziswa esiteshini ukuze kuqhunyiswe i-ejenti ye-deoxidizing, futhi ifakwe umfutho womoya ojikelezayo.

3. Mandrel Lubrication

Uma umphumela wokugcoba we-mandrel ungalungile noma izinga lokushisa le-lubricant ye-mandrel liphansi kakhulu, kuzokwenzeka izibazi zangaphakathi. Ukuze kwandiswe izinga lokushisa le-mandrel, kungenziwa indlela eyodwa kuphela yokupholisa amanzi okupholisa. Phakathi nenqubo yokukhiqiza, kuyadingeka ukulawula ngokuqinile izinga lokushisa le-mandrel ukuze uqinisekise ukuthi izinga lokushisa elingaphezulu le-mandrel lingu-80-120 ° C ngaphambi kokufafaza i-lubricant, futhi izinga lokushisa le-mandrel akufanele libe ngaphezu kuka-120 ° C. isikhathi eside, ukuze kuqinisekiswe ukuthi i-lubricant ebusweni yomile futhi iminyene ngaphambi kokubhoboza ngaphambili , Umqhubi kufanele ahlole njalo isimo sokugcoba se-mandrel.
