Incazelo emfushane:

I-molybdenum (TZM) yokubhoboza i-mandrel iyingxenye ebalulekile esetshenziswa ezinqubweni zokwenza insimbi yokushisa okuphezulu.Ivamise ukwenziwa ngengxubevange ye-molybdenum (TZM alloy), enamandla amakhulu ezinga lokushisa eliphezulu nokumelana ne-oxidation.I-mandrel yokubhoboza isetshenziswa ngokuyinhloko ekuqhumeni kwensimbi yesithando somlilo ukushaya umoya-mpilo esithandweni somlilo ukuze kuthuthukiswe i-oxidation nokuxubana kwensimbi.Ukuzinza kwezinga lokushisa eliphezulu nokumelana nokugqwala kwama-mandrels abhobozayo e-molybdenum (TZM) kuwenza abe yingxenye ebalulekile enqubweni yokwenza insimbi.
