Izinhlobonhlobo zezakhiwo zokucubungula zezinduku zethusi

Ama-Brass rods anokusebenza okubanzi kakhulu okuvumelana nezimo: ngesikhathi sokusebenza okushisayo (600-800℃), ipulasitiki yawo iphakeme kunethusi elimsulwa, okuwenza afanelekele ukukhipha amaphrofayela amakhulu. Ngesikhathi sokusebenza okubandayo (njengokudweba okubandayo nokugoqeka okubandayo), ubulukhuni bungalawulwa ngokulungisa okuqukethwe kwe-zinc ukuze kuhlangatshezwane nezidingo zokunemba kobukhulu bezingxenye ezinembayo. Ngaphezu kwalokho, ithusi linokusebenza okuhle kakhulu kokusika (ikakhulukazi ithusi eliqukethe umthofu), ngesivinini sokusika esifinyelela izikhathi ezingu-2 kuya kwezi-3 kunethusi elihlanzekile. Izinga lokugqoka lamathuluzi liphansi, lithuthukisa kakhulu ukusebenza kahle kokucutshungulwa kwemishini.
